A measure of a baseball player's ability to hit for power, and along with on-base percentage, one of the two most important statistics for measuring the ability of a hitter. Usually abbreviated .SLG, it is a more useful stat than the RBI, because it's an isolated statistic (it doesn't rely on other players).

To calculate slugging percentage... use the following formula:

 TB/AB 

 TB = total bases (3*HR + 2*3B + 1*2B + H)
 AB = at-bats
The word "percentage" is a little misleading, as the maximum value is not 1.000, but rather 4.000.
