On base percentage
(Redirected from On base average)
<math>OBP = \frac{H+BB+HBP}{AB+BB+HBP+SF}<math>
In baseball statistics, on base percentage (OBP) (sometimes referred to as on base average (OBA)) is a measure of how often a batter gets to first base for any reason other than a fielding error or a fielder's choice.
Though extremely unlikely, it is possible for a player's on base percentage to be lower than his batting average (H/AB). If a player had 2 hits and 5 at bats with a sacrifice fly, his batting average would be .400, but his on base percentage would be .333.
