On-base percentage

In baseball statistics, on-base percentage (OBP), also known as on-base average/OBA, measures how frequently a batter reaches base. It is the ratio of the batter's times-on-base (TOB) (the sum of hits, walks, and times hit by pitch) to their number of plate appearances. OBP does not credit the batter for reaching base due to fielding error, fielder's choice, dropped/uncaught third strike, fielder's obstruction, or catcher's interference. An official MLB statistic since 1984, it is sometimes referred to as on-base average/OBA, as it is rarely presented as a true percentage.
