List of Major League Baseball career total bases leaders
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.
