'''On-base percentage''' (abbreviated '''OBP''') is a [[baseball]] [[statistic]] designed to track the rate at which a hitter reaches base as a result of his own actions (as opposed to, for example, defensive lapses). Another way to interpret OBP is the percentage of a player's plate appearances that he does not make an out.

The formula for on-base percentage is

<math>OBP = \frac{H+BB+HBP}{AB+BB+HBP+SF}</math>

where

*''H'' is Hits

*''BB'' is Walks

*''HBP'' is times hit by a pitch

*''AB'' is At bats

*''SF'' is Sacrifice Flies

Because there is a high correlation between OBP and runs scored, the use of on-base percentage in player evaluation has gained favor among baseball enthusiasts and front offices in recent years.
