**How to Calculate:**

BB + (TB – H) + (SB – CS) / AB = Secondary Average

BB – Walks

TB – Total Bases

H – Hits

SB – Stolen Bases

CS – Caught Stealing

AB – At Bats

**About Secondary Average:**

Secondary Average is a stat created by Bill James, which measures a hitter’s performance and looks to evaluate the number of bases a player has gained separate of batting average. Secondary average, unlike batting average, calculates power, plate discipline and speed.
