The 50 Greatest Regular Seasons in MLB History

The first of Connie Mack's three consecutive AL pennant winners. Al Simmons, Jimmie Foxx, Mickey Cochrane, and Mule Haas formed one of the most explosive lineups of the era, scoring 901 runs. Lefty Grove went 20-6. The team led the AL in runs scored by over 100. The World Series against the Cubs featured one of the greatest comebacks in Fall Classic history - Game 4, with the Cubs leading 8-0 in the seventh inning, the Athletics scored 10 runs to win 10-8. The 1929-1931 Athletics dynasty - three consecutive pennants, two World Series titles, three seasons above .690 - is one of the most underrated stretches of sustained excellence in baseball history. The Ruth-era Yankees shadow followed them everywhere and still does.

The 1995 Cleveland Indians played only 144 games due to the lingering effects of the 1994 strike, but their .694 winning percentage ranks among the highest in the live-ball era. Albert Belle hit 50 home runs and drove in 126. Eddie Murray, Manny Ramirez, Jim Thome, Carlos Baerga, and Kenny Lofton surrounded him with a lineup that had no breaks in it. Orel Hershiser anchored the rotation. Cleveland dominated the AL Central by 30 games and swept through the playoffs. The World Series loss in six games to Greg Maddux's Braves was a painful end to a season of historic quality. In a full 162-game schedule, extrapolated from their rate, this team would have finished around 113-49 - good enough to rank considerably higher on this list.

One of the most overlooked dynasties in baseball history. The 1942 Cardinals won 106 games, led the NL in runs scored, batting average, on-base percentage, and slugging - then beat the heavily favoured Yankees in the World Series. Stan Musial was establishing himself as a force. Enos Slaughter was the offensive anchor. Mort Cooper went 22-7 and won the NL Cy Young equivalent. The pitching staff allowed fewer than 500 runs. What makes this extraordinary is the continuity: the following year, with several players departed for military service, they still went 105-49. The 1942-1944 Cardinals won 316 games in three seasons - a wartime dynasty that operated in the shadow of the Yankees mythology and has never received full historical credit.

The most recent 110-win team in baseball history and the closest anyone has come to the 116-win record since 2001. Freddie Freeman's first year in Los Angeles. Mookie Betts at his defensive best. Clayton Kershaw's finest final-act vintage. Julio Urias breaking out. The Dodgers led the NL in runs scored and ERA, won the NL West by 22 games, and looked in October like a team that would coast to the championship. Then the San Diego Padres - who had gone 89-73 in the regular season - eliminated them in five NLDS games. It was one of the most startling upsets of the analytics era. The 2022 Dodgers will be remembered primarily for what happened in October, but the regular season they produced was genuinely historic.

The third consecutive 100-win Cardinals season during the war years, and the second World Series title. Musial hit .347. Walker Cooper caught and hit .317. Marty Marion won the NL MVP award at shortstop - one of the few times in baseball history the prize went to a middle infielder on a team of this calibre. Mort Cooper, Harry Brecheen, and Max Lanier provided a three-headed rotation that was comfortably the best in the NL. The World Series was the only all-St. Louis Fall Classic in history, played at Sportsman's Park with the Cardinals defeating the Browns in six games. The 1942-1944 Cardinals represent arguably the most consistent three-year run in NL history - three seasons at .682 or better, three pennants, two World Series titles.

The middle year of the Cardinals' wartime dynasty, and in many ways the most remarkable: having beaten the Yankees in the 1942 World Series with most of their core roster intact, the 1943 Cardinals lost Stan Musial and several others to military service and still went 105-49. Mort Cooper led the NL with 21 wins. Marty Marion and Whitey Kurowski anchored the infield. The pitching staff allowed fewer than 490 runs - outstanding for the era. The Yankees got revenge in five World Series games, but the Cardinals' regular season achievement stood entirely on its own terms. Winning 105 games in the middle of a wartime baseball landscape, with a depleted roster, against competition that was also losing its best players, required a depth of organisational talent that the Cardinals of this era clearly possessed.

The Boys of Summer at their offensive peak. The 1953 Dodgers scored 955 runs - more than any NL team since the 1930s slugging era. Roy Campanella won his second MVP award, hitting .312 with 41 home runs and 142 RBI. Carl Furillo won the batting title at .344. Duke Snider, Gil Hodges, Pee Wee Reese, Jackie Robinson, Jim Gilliam - the lineup was a Hall of Fame ballot in progress. Carl Erskine went 20-6 on the mound. The October heartbreak, as so often with Brooklyn in this era, came against the Yankees - beaten in six games, the fifth time in seven attempts that Brooklyn reached the World Series against New York and came up short. "Wait till next year" would have to wait two more years. The 1953 season was the finest regular season the Dodgers franchise produced in Brooklyn.

Ted Williams returned from military service for 1946 and the results were immediate: a .342 average, the AL MVP award, and 104 wins for the Boston Red Sox. They finished 12 games ahead of Detroit. Tex Hughson, Dave Ferriss, and Joe Dobson gave Boston a formidable rotation. The World Series loss to the Cardinals in seven games is one of the most painful in Red Sox history - defined by Enos Slaughter's famous "mad dash" home from first base in the eighth inning of Game 7 on a single, while shortstop Johnny Pesky appeared to hold his relay throw. Williams hit just .200 against St. Louis's shift. It was the beginning of another chapter in what Red Sox fans would come to call the Curse. The talent was genuine. The October ending was not.

Earl Weaver's first full season as manager produced a 109-win team that was an overwhelming World Series favourite. Boog Powell, Frank Robinson, and Brooks Robinson anchored the lineup. Mike Cuellar, Dave McNally, and Jim Palmer gave Baltimore a rotation that was arguably the best in the AL. The Orioles finished 19 games ahead of Detroit. The World Series loss to the "Miracle Mets" in five games - with Tommie Agee making two outstanding catches in Game 3 and the Mets running the table from Game 1 onwards - stands as one of the great upsets in Fall Classic history. The fact that the 1970 Orioles came back with essentially the same roster and won the World Series the following year confirms the quality was real. The Mets were just better in that particular October.

The 1970 Orioles returned after the heartbreak of the 1969 World Series with a point to prove. The core was identical: Boog Powell, Frank Robinson, Brooks Robinson - who would deliver the most famous defensive World Series performance in history - and the rotation of McNally, Cuellar, and Palmer. Baltimore finished 15 games ahead of the Yankees and won the AL East with something approaching contempt for the competition. They beat the Reds in five games in the World Series, with Brooks Robinson making catch after catch at third base that turned the series into something that has been replayed on highlight reels ever since. It was the redemption the 1969 team deserved, one year too late.

The Big Red Machine. Pete Rose, Johnny Bench, Joe Morgan, Tony Perez - a lineup that has entered baseball mythology alongside Murderers' Row and the Boys of Summer. The 1975 Reds won 108 games and won the NL pennant by 20 games. They led the NL in runs scored. The World Series against the Red Sox produced one of the greatest games in baseball history in Game 6 - Carlton Fisk's waving-fair home run in the 12th inning - before the Reds won Game 7 the following night. Joe Morgan's ninth-inning single drove in the deciding run. The 1975-1976 Reds won back-to-back championships across 210 combined wins - the most dominant two-year stretch of the modern era until the late-1990s Yankees matched and exceeded it.

The 1986 Mets were 108-54 and the most feared team in baseball - not always for the right reasons, but feared nonetheless. Dwight Gooden was 17-6 coming off his 24-4, 1.53 ERA Cy Young season the previous year. Ron Darling and Bob Ojeda added depth to the rotation. Darryl Strawberry and Keith Hernandez anchored a lineup that led the NL in runs scored. The team won the NL East by 21.5 games. The World Series against the Red Sox produced one of the most dramatic moments in October history - Mookie Wilson's grounder through Bill Buckner's legs in Game 6 to extend the series, followed by a Game 7 Mets victory. It was the most complete Mets team ever assembled, and arguably the only New York Mets team that legitimately belonged on a list like this one.

The 2018 Red Sox are the best team Alex Cora ever managed and one of the finest in Boston history. Mookie Betts won the AL MVP and played Gold Glove right field. J.D. Martinez drove in 130 runs in his first Boston season. Chris Sale, David Price, and Rick Porcello gave the rotation genuine depth. They won the AL East by eight games in a division that housed three 90-win clubs. In the postseason they beat the Yankees, Astros, and Dodgers - three teams that had combined for 314 wins during the regular season - losing just four games across eleven playoff series games. The World Series victory in five games over the Dodgers made this one of the most complete seasons in Red Sox history, and one of only a handful of modern teams to convert a 108-win regular season into a championship.

The second of Connie Mack's three consecutive pennant-winning Athletics clubs. The 1930 season is notable for being played during one of the most offensively inflated environments in baseball history - the entire NL hit .303 as a league - which is why the Athletics' run total of 951 needs context. Lefty Grove was magnificent again: 28-5 with a 2.54 ERA in a year when pitching was being devastated across the game. Mickey Cochrane, Al Simmons, and Jimmie Foxx formed one of the most powerful lineups in baseball. The World Series win over the Cardinals in six games was a championship that often gets overlooked because the 1929 and 1931 editions of the same dynasty are more frequently discussed. As a regular season, it sits comfortably in the top 30.

The 2019 Houston Astros won 107 games with one of the most powerful lineups in the modern game: Alex Bregman, Jose Altuve, Carlos Correa, Yordan Alvarez, George Springer, and Michael Brantley gave Houston an eight-through-lineup that had virtually no weak spots. Gerrit Cole, Justin Verlander, and Zack Greinke made them the heaviest World Series favourites in years. The World Series loss to the Washington Nationals - in which the road team won every game of a seven-game series, a first in World Series history - was a genuinely stunning result. The subsequent revelation of Houston's sign-stealing system in 2017 cast a retrospective shadow over the entire dynasty, but the 2019 regular season was played under the scrutiny that followed 2017's revelations and still produced 107 wins on the strength of genuine talent.

The 2021 Giants were the great baseball surprise story of the modern analytics era. A team whose best player, Buster Posey, was 34 years old and coming out of a year away from the game. A team managed by Gabe Kapler with a depth chart that nobody feared in April. They went out and won 107 games - more than any Giants team since the pre-World War II era - by playing the most complete, consistent baseball in the National League. Brandon Crawford had an MVP-calibre season. Brandon Belt found his best form. The pitching staff was deep and varied. They finished one game ahead of the Dodgers in the NL West, then lost to them in five games in the NLDS. The run differential of +155 is the lowest on this list, which suggests some fortune was involved. But 107 wins earns its place regardless.

The 2019 Dodgers won 106 games and had the best run differential in the NL by a considerable margin. Cody Bellinger won the NL MVP. Clayton Kershaw, Walker Buehler, and Hyun-Jin Ryu anchored a rotation that was collectively the best in the NL. The bullpen was a rotating cast of specialists who between them produced one of the lowest combined ERA figures in the modern game. The NLCS loss to the Washington Nationals - who had finished 19 games behind Los Angeles in the regular season - was the second consecutive October underperformance for a Dodgers team that clearly had the talent to win a championship. They would finally claim it the following year in the bubble World Series of 2020. The 2019 regular season, with a +250 run differential and 106 wins, was the finest they produced in the decade.

Tony La Russa's 2004 Cardinals won 105 games and dominated the NL Central. Albert Pujols was at the absolute peak of his powers, putting up numbers - .331 average, 46 home runs, 123 RBI - that would be career highlights for most players. Scott Rolen added 34 home runs. Jim Edmonds, Larry Walker, and Reggie Sanders gave La Russa depth that other managers could only envy. Chris Carpenter, Jason Marquis, and Matt Morris anchored a rotation that kept opponents under control. The World Series loss to the Red Sox was emphatic - swept in four games by a Boston team on a historic tear after their remarkable ALCS comeback. But the 2004 Cardinals built one of the finest regular seasons in modern NL history. Pujols was simply otherworldly that year.

Tony La Russa's Oakland Athletics were the most feared team in baseball by 1988. Jose Canseco became the first player in history to hit 40 home runs and steal 40 bases in the same season - the 40-40 club. Dave Stewart went 21-12. Dennis Eckersley saved 45 games with an ERA of 2.35 and became the prototype for the modern closer role. The A's won the AL West by 13 games and were overwhelming World Series favourites. The loss to the Dodgers - sparked by Kirk Gibson's iconic hobbling home run off Eckersley in Game 1, a pinch-hit shot that shifted the entire series in one swing - is one of the great October upsets of the modern era. The A's would come back in 1989 and 1990, winning it in 1989. But 1988 should have been the first of three titles.

The 1984 Tigers were one of the most dominant teams of the modern era to finish the job. They started 35-5 - still among the hottest starts in baseball history - and never really looked back. Sparky Anderson managed a team built around Jack Morris on the mound, Alan Trammell and Lou Whitaker in the middle infield, Kirk Gibson in the outfield, and Lance Parrish behind the plate. Morris went 19-11 and was the ace of a rotation that gave up runs sparingly. They won the AL East by 15 games and beat the Padres in five World Series games, with Morris winning Game 4. It was the Tigers' first championship since 1968 and the only one they've won since. The 1984 season remains the finest the franchise has produced since the live-ball era began.

The 2017 Dodgers won 104 games, won the NL West by 11 games, and reached the World Series for the first time since 1988. Clayton Kershaw was still at the height of his powers. Cody Bellinger won the NL Rookie of the Year. Justin Turner, Corey Seager, and Chris Taylor formed a lineup that was relentless. The World Series against the Astros was one of the greatest in history - five of the seven games decided in the final at-bat, three walk-offs, and a Game 5 featuring multiple lead changes that lasted over five hours. Houston won Game 7 at Dodger Stadium. The subsequent sign-stealing revelations gave the 2017 World Series a permanently asterisked quality, but the Dodgers' regular season excellence was clean and real.

"Next Year" finally arrived. The 1955 Brooklyn Dodgers won 98 games, their best total in the live-ball era, and then accomplished what five previous Brooklyn teams had failed to do: beat the Yankees in the World Series. Roy Campanella won his third MVP award at .318 with 32 home runs. Duke Snider hit 42. The core of Robinson, Reese, Hodges, Furillo, and Gilliam remained largely the same as the 1953 team that had broken hearts again. Don Newcombe went 20-5 on the mound. Johnny Podres shut out the Yankees in Game 7, with Sandy Amoros making a miraculous running catch in the sixth inning that preserved the lead. The championship captured a city, delivered a franchise's only title, and has remained one of baseball's most emotionally complete stories ever since.

The 2016 Cubs ended a 108-year championship drought, and the regular season they put together was worthy of the occasion. With Jon Lester, Jake Arrieta, Kyle Hendricks, and John Lackey in the rotation, this was arguably the deepest pitching staff in the NL. Kris Bryant won the NL MVP. Anthony Rizzo anchored first base and the lineup. Addison Russell, Ben Zobrist, and Dexter Fowler completed a team that had no obvious vulnerabilities on paper. They won the NL Central by 17.5 games and had the best run differential in the NL. The World Series against Cleveland went seven games, with the Cubs trailing three games to one before winning three straight including a rain-delayed, extra-innings Game 7 on the road. A run differential of +252 in the regular season makes this one of the more dominant 103-win teams in history.

The third consecutive American League pennant for Tony La Russa's Oakland Athletics, and the third consecutive year in which a team with every reason to win the World Series did not. After being upset by the Dodgers in 1988 and winning it all in 1989, the 1990 A's went 103-59 and were again among the sport's heaviest October favourites. Dave Stewart won 22 games. Bob Welch won the Cy Young with 27 wins. Rickey Henderson won the AL MVP. Dennis Eckersley saved 48 games. The four-game World Series sweep by the Reds - featuring a Jose Rijo masterclass and an Eric Davis home run in Game 1 - was one of the most shocking in Fall Classic history. Three pennants, one championship - the 1988-1990 A's dynasty produced regular season excellence that October never properly rewarded.

The 1971 Orioles achieved one of the most extraordinary pitching feats in baseball history: four 20-game winners in the same rotation. Dave McNally (21-5), Mike Cuellar (20-9), Pat Dobson (20-8), and Jim Palmer (20-9) all cleared 20 wins - a rotation record that has never been matched. Baltimore won 100 games and dominated the AL East. The World Series loss to the Pittsburgh Pirates in seven games is remembered for Roberto Clemente's extraordinary performance across the series and Frank Robinson's home run in Game 2. The 1971 Orioles are third in a remarkable three-year run for the franchise (1969-1971) that produced a combined record of 318-140 and one World Series title, with two losses in the others. The pitching depth alone earns them a place on this list.

The "Year of the Pitcher" in MLB - 1968 saw Bob Gibson post a 1.12 ERA and Denny McLain win 31 games, two achievements so extreme they triggered rule changes the following season. McLain's 31 wins remains the last time any starter cleared 30 - a mark that will almost certainly never be reached again. The Tigers won 103 games behind McLain and Mickey Lolich, with Al Kaline and Willie Horton anchoring the lineup. The World Series against the Cardinals featured one of the great individual performances in October history by Lolich, who won three complete games including Game 7. McLain won only once despite his regular season dominance. Gibson and Lolich together produced the most spectacular pitching duel the Fall Classic had seen in decades. Detroit's championship was earned over a brutal season in a year when pitchers ruled the sport.

The 2017 Houston Astros won their first World Series championship and produced one of the most talented rosters in the modern game - a lineup built through years of deliberate tanking and drafting that was vilified when the losses were piling up and celebrated when the wins arrived. Jose Altuve won the AL MVP. Carlos Correa, Alex Bregman, and George Springer surrounded him. Justin Verlander, acquired at the trade deadline, was perhaps the single most important deadline addition in baseball history - winning five of his seven Houston regular season starts at a combined 1.06 ERA. The subsequent sign-stealing scandal has permanently complicated how this season and this team are viewed historically. The wins were real. So was the cheating. History will continue to argue about where the 2017 Astros belong.

The second of the Big Red Machine's back-to-back championships. The 1976 Reds were perhaps slightly less dominant in the regular season than the 1975 version - 102 wins versus 108 - but more efficient in October, sweeping both the Phillies in the NLCS and the Yankees in the World Series without losing a game. Joe Morgan won his second consecutive NL MVP award. Pete Rose, Johnny Bench, Ken Griffey Sr., George Foster, and Tony Perez made this one of the deepest batting orders of the decade. The sweep of the Yankees - in their first World Series since 1964, Reggie Jackson's debut season in New York - was a reminder that the Reds were genuinely the best team in baseball across two years, not a single-season wonder. Combined, the 1975-76 Reds won 210 games - a benchmark of sustained team excellence.

Bob Gibson's Cardinals were the class of the NL in the second half of the 1960s. The 1967 team won 101 games and completed the job with a World Series victory over the "Impossible Dream" Red Sox - the classic October confrontation between the game's most dominant pitcher and one of the most romantic underdog stories in baseball history. Gibson won three World Series games and posted a 1.00 ERA across 27 innings. Orlando Cepeda won the NL MVP. Lou Brock stole seven bases in the Fall Classic. Mike Shannon, Roger Maris in his final season, and Julian Javier gave La Russa - wait, given Red Schoendienst - a balanced lineup. The run differential of +138 is the second lowest on this list, suggesting the Cardinals won more close games than their talent strictly warranted. But 101 wins earns the spot.

The 1948 Cleveland Indians won the World Series in what remains one of the more complete team performances of the post-war decade. Bob Feller, Bob Lemon, and Gene Bearden formed one of the finest rotations in the AL. Larry Doby became a genuine force. Lou Boudreau, the player-manager, had one of the finest seasons of his career - hitting .355 with 18 home runs and winning the AL MVP. The Indians finished tied with the Red Sox after 154 games, requiring a one-game playoff - which Cleveland won on the strength of Bearden's complete game. The subsequent World Series sweep of the Braves in six games was convincing. It was the last time the Indians franchise won a World Series, a drought that stretched to the franchise's Cleveland era-ending move. The +272 run differential makes this one of the most dominant teams on the lower half of this list.

The 1969 Mets are the only team on this list ranked primarily on the basis of what they meant rather than what their numbers said. A run differential of +91 is by far the lowest on the list, and .617 is the lowest winning percentage. But 100 wins is 100 wins, and the Mets won theirs as a team that had finished ninth in the NL just three years earlier. Tom Seaver (25-7) and Jerry Koosman formed a two-ace tandem that was legitimately elite. Tug McGraw from the bullpen. Cleon Jones, Tommie Agee, and Donn Clendenon providing enough offence. The World Series upset of the Baltimore Orioles - a team with 109 regular season wins and every rational advantage - was one of the great results in baseball history. The Mets earned their place here not by dominating but by becoming the definitive proof that October baseball follows no rules.
