			In [[baseball statistics]], '''slugging percentage''' (abbreviated '''SLG''') is a popular measure of the power of a [[batting (baseball)\|hitter]]. It is calculated as [[total bases]] divided by [[at bat]]s:

			<math>SLG = \frac{(\mathit{1B}) + (2 \times \mathit{2B}) + (3 \times \mathit{3B}) + (4 \times \mathit{HR})}{AB}</math>

			where ''AB'' is the number of at-bats for a given player, and ''1B'', ''2B'', ''3B'', and ''HR'' are the number of [[single (baseball)\|singles]], [[double (baseball)\|doubles]], [[triple (baseball)\|triples]], and [[home run]]s, respectively. [[Base on balls\|Walks]] are specifically excluded from this calculation. The name is a [[misnomer]], as the statistic is not a [[percentage]] but a scale of [[Measure (mathematics)\|measure]] whose computed value is a [[real number]] in the [[Interval (mathematics)\|interval]] <math>\left[0, 4\right]</math>.

			For example, in 1920, [[Babe Ruth]] played his first season for the [[New York Yankees]]. In 458 at bats, Ruth had 172 hits, comprising 73 singles, 36 doubles, 9 triples, and 54 home runs, which brings the total base count to (73 × 1) + (36 × 2) + (9 × 3) + (54 × 4) = 388. His total number of bases (388) divided by his total at-bats (458) is .847, his slugging percentage for the season. The next year he slugged .846, and these records went unbroken until [[2001 in baseball\|2001]], when [[Barry Bonds]] achieved 411 bases in 476 at-bats, bringing his slugging percentage to .863, unmatched since.

			==Significance==
			[[File:IMG 9762 Carlos Beltrán.jpg\|thumb\|[[Carlos Beltrán]] holds the highest slugging percentage in the history of the [[Major League Baseball postseason]].]]
			Long after it was first invented, slugging percentage gained new significance when baseball analysts realized that it combined with [[on-base percentage]] (OBP) to form a very good measure of a player's overall offensive production (in fact, OBP + SLG was originally referred to as "production" by baseball writer and statistician [[Bill James]]). A predecessor metric was developed by [[Branch Rickey]] in 1954. Rickey, in ''[[Life (magazine)\|Life]]'' magazine, suggested that combining OBP with what he called "extra base power" (EBP) would give a better indicator of player performance than typical [[Triple Crown (baseball)\|Triple Crown]] stats. EBP was a predecessor to slugging percentage.<ref>{{cite web\|url= http://old.nationalreview.com/weekend/play-ball/pb-lewis033101.shtml \|title= Lies, Damn Lies, and RBIs\|accessdate=2012-07-01\|date=2001-03-31\|first=Dan\|last=Lewis \|publisher= nationalreview.com}}</ref>

			[[Allen Barra]] and [[George Ignatin]] were early adopters in combining the two modern-day statistics, multiplying them together to form what is now known as "SLOB" (Slugging × On-Base).<ref>{{cite web\|url=http://www.salon.com/news/sports/col/barra/2001/06/20/bonds/print.html\|title=The best season ever?\|accessdate= 2007-07-15\|date= 2001-06-20\|first=Allen\|last= Barra\|publisher=Salon.com}}</ref> [[Bill James]] applied this principle to his [[runs created]] formula several years later (and perhaps independently), essentially multiplying SLOB × At-Bats to create the formula:

			<math>RC=\frac{(Hits+Walks)(Total Bases)}{At Bats+Walks}</math>

			In 1984, [[Pete Palmer]] and [[John Thorn]] developed perhaps the most widespread means of combining slugging and on-base percentage: [[On-base plus slugging\|OPS]]. "OPS" simply stands for "on-base plus slugging", and is a simple addition of the two values. Because it is easy to calculate, OPS has been used with increased frequency in recent years as a shorthand form to evaluate contributions as a [[Batting (baseball)\|batter]].

			==Perfect slugging percentage==
			The maximum numerically possible slugging percentage is 4.000. A few dozen players throughout history (107 as of August 2010) have momentarily had a 4.0 career average by homering in their first major league at-bat.

			No player has ever retired with a 4.000 slugging percentage, but five players tripled in their only at-bat and therefore share the ML record, when calculated without respect to games played or plate appearances, of a career slugging percentage of 3.000. The players (and the seasons in which they had their only at-bat) were: [[Eric Cammack]] (2000 Mets); [[Scott Munninghoff]] (1980 Phillies); [[Eduardo Rodríguez (baseball)\|Eduardo Rodriguez]] (1973 Brewers); and [[Charlie Lindstrom]] (1958 White Sox)<ref>{{cite news\| url=http://www.nydailynews.com/sports/baseball/2010/05/29/2010-05-29_baseballs_triple_threats.html \| location=New York \| work=Daily News \| title=Ex-Met Eric Cammack is one of only four players to post career slugging percentage of 3.000 \| first=Jesse \| last=Spector \| date=2010-05-29}}</ref>
