Slugging percentage
From BR Bullpen
(Redirected from Slugging Percentage)
Slugging percentage (abbreviated SLG and also called Slugging average) is the number of total bases divided by the number of at bats.
Its formula is ([Singles] + [Doubles x 2] + [Triples x 3] + [Home Runs x 4])/[At Bats]
At bats are different than plate appearances.
An equivalent formula is ([Hits] + [Doubles] + [Triples x 2] + [Home Runs x 3])/At Bats
This formula is not as intuitive, but is often more convenient, as singles are often not given (although they could easily be deduced). Singles can be figured fom the following equation because they are simply hits that are not for extra bases: (Hits - [Doubles + Triples + Home Runs])
