It only includes hits (not walks and hit-by-pitches) and assigns extra value to extra-base hits. This makes it a good measure of a player&#8217;s power.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-is-slg-used\">How is SLG used?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike batting average, SLG differentiates between kinds of hits. It values doubles more than singles; triples more than doubles; and home runs more than triples. Since extra-base hits are generally better than singles, it&#8217;s useful to have a stat that reflects that.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since the league average in SLG is usually around .400, a good slugging percentage is above .400. The best hitters will have at least a .500 SLG.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-slugging-percentage-formula\">Slugging Percentage Formula<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The slugging percentage formula is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>SLG = (Singles\u00a0+ (2 \u00d7\u00a0Doubles)\u00a0+ (3 \u00d7\u00a0Triples)\u00a0+ (4 \u00d7\u00a0Home Runs)) \u00f7\u00a0<a href=\"https:\/\/www.baseball-reference.com\/bullpen\/At_Bats\">At Bats<\/a><\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\"><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-slg-examples\">SLG Examples<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-using-slugging-percentage-formula-1\">Using Slugging Percentage Formula #1<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Let&#8217;s look a a real-life example to learn how to use the first slugging percentage formula. During the 2024 season, <a href=\"https:\/\/www.baseball-reference.com\/players\/gl.fcgi?id=judgeaa01&amp;t=b&amp;year=2024\">Aaron Judge<\/a> recorded 180 hits, 36 doubles, 1 triple, and 58 home runs in 559 at bats. First, we need to find how many singles Judge hit.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Subtract doubles, triples, and home runs from total hits. 180-(36+1+58) = 85.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Judge hit 85 singles. Now, let&#8217;s plug that into the slugging percentage formula.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Multiply Judge&#8217;s extra-base hits by their respective values. 2*36 = 72. 3*1 = 3. 4*58 = 232.<\/li>\n\n\n\n<li>Add up the total bases from Judge&#8217;s hits. 85+72+3+232 = 392.<\/li>\n\n\n\n<li>Divide Judge&#8217;s total bases by his at bats. 392\/559 = .701.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Judge had a .701 SLG in 2024.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-slugging-percentage-calculator\">Slugging Percentage Calculator<\/h2>\n\n\n<style>@media (max-width:480px){#cff-iframe-1{min-height:665px;}}@media (max-width:768px){#cff-iframe-1{min-height:568px;}}@media (max-width:1024px){#cff-iframe-1{min-height:439px;}}@media (min-width:1024px){#cff-iframe-1{min-height:392px;}}<\/style><script data-category=\"functional\" type=\"text\/javascript\">window.addEventListener(\"message\", function(e) {\n\t\t\t\t\t\t\tif (\"data\" in e && typeof e.data == \"object\" && !
