Definition of Home Runs O/U

What is the definition of the term "Home Runs O/U"? What is meant by the term "Home Runs O/U"?

The term "Home Runs O/U" refers to the Over/Under betting line for whether a specific player will hit a home run in a given game.

Sportsbooks typically set this line at 0.5 home runs, meaning you're betting on whether the player will hit at least one home run (Over) or none at all (Under).

This is a straightforward player prop bet:

Take the Over - you need the player to hit a home run.

Take the Under - any game without a home run is a winning bet.

The odds are shaped by recent performance and matchup context. For example:

Blaze Alexander might be listed at 10.50 to hit Over 0.5 HRs and 1.058 for the Under, signaling a low probability of a home run.

Corbin Carroll, with one home run in his last five games, might be offered at 4.00 for the Over and 1.26 for the Under.

Lourdes Gurriel, with no homers in his last five, could have odds of 8.00 on the Over and 1.09 on the Under.

These numbers reflect both the implied probability and potential payout if the player does or doesn't go deep. Because the line is always set at 0.5, there's no chance of a push - it's a simple yes-or-no outcome.

This market is popular with baseball fans and bettors who follow player form, pitcher matchups, and ballpark factors. It's also frequently included in Same Game Parlays, where bettors look to build a story around a single contest.
