OPS is a stat that combines two major functions in a baseball player's every day life, getting on base and hitting for power. OPS is basically your on base percentage (OBP) added with your slugging percentage (SLG).


Like I said in the intro to this series no sabermetric stat is perfect and no sabermetric stat is a "tell all" stat. The biggest beef with OPS is how it weighs on base and slugging equally, which seems "unfair" for those who are not big power hitters. Slugging percentage numbers average between 75-100 points higher then on base numbers traditionally in baseball over a full season. I do not believe in totally disqualifying stats because they are not "fair" because you have to know what stat to use for each situation and each player. You do not define Derek Jeter by his OPS because he is not a power hitter, he is a lead off hitter. A lead off hitter is defined mainly by their ability to get on base (OBP) and set the tone for the rest of the team. You want your best hitter, the #3 hitter traditionally, and your clean up hitter to have higher OPS numbers.
