In
baseball statistics, total bases (TBs) refers to the number of bases a player has gained with
hits, i.e., the sum of his hits
weighted by 1 for a
single, 2 for a
double, 3 for a
triple and 4 for a
home run. Only bases attained from
hits count toward this total. After a player collects a hit, whether it be a single, double, triple or home run, the total bases stat can be applied. Whether or not this player advances further during the inning, by stealing a base or advancing off another players hit, does not increase his/her total base number.
