Total Bases TB
TB stands for total bases in baseball. Every base a hitter reached on his hits: one for a single, two for a double, three for a triple, four for a home run.
How TB is calculated
Total bases divided by at-bats is slugging percentage. Walks and hit-by-pitches earn no total bases, which is the gap OPS closes by adding OBP.
