Definition – What is Times on Base?

TOB is a hitting metric. The higher the number, the more times the batter has gotten on base.

TOB is the number of times a batter has gotten on base through a hit, walk, or being hit by the pitch. It does not include arriving on base through any other method (errors, uncaught third strikes, fielder’s choice, or fielder’s obstruction).

Formula – How to calculate TOB

TOB = Hits + Walks + Hit by Pitch

Example

If a batter has 164 hits, 22 walks, and 4 times being hit by a pitch, then:
TOB = 164 + 22 + 4
TOB = 190
This batter has been on base 190 times according to this statistic (they may have been on base more times through other methods, however).
