Understand Sabermetrics : Slugging Percentage (SLG)
Slugging percentage is another one of those "oldie but a goodie" kind of SABR stats because it seems like it has been around forever, and is still commonly used. SLG is obviously used to measure power hitters and their ability to get extra base hits and home runs.
The highest single season SLG% was recorded in 2001 when Barry Bonds posted an .863 SLG%. The highest career SLG% is Babe Ruth's mark of .690. The highest possible SLG% you can have is 4.000, although you would have to hit a grand slam in your ONLY MLB at bat to achieve this.
