In baseball statistics, the term times on base (TOB), is the cumulative total number of times a batter has reached base as a result of a hit, base on balls, or hit by pitch. This statistic does not include times reaching base by way of an error, uncaught third strike, fielder's obstruction or a fielder's choice, making the statistic somewhat of a misnomer.
