(Redirected from Adjusted OPS)
"I don't understand. All of a sudden, it's not just BA and Runs Scored, it's OBA. And what is it with O P S ?" - Harold Reynolds in 2004
OPS is the abbreviation for On-Base Plus Slugging (occasionally referred to as Offensive Production Statistic), a common statistic used by sabermetricians to judge a player's overall offensive performance. OPS is the sum of on-base percentage and slugging percentage.
There are many variations on OPS that try to account for the different values of getting on base and slugging, with the most prominent being Gross Production Average.
An important modification of OPS is Adjusted OPS or OPS+, which adjusts the OPS to account for the ballpark and the league that the player played in. In addition, the number is "normalized", so that the median is 100, with better-than-average scores above 100. A single-season OPS+ performance of 140 or higher could be considered a Hall of Fame level performance for that season. As an example, the 2006 American League leader in OPS+ was Travis Hafner, with a 179. In terms of career performance, the top 100 players have a career OPS+ of 136 or higher. Baseball-reference.com includes "OPS+" among the stats that can be viewed for each batter, and some serious fans consider it the best quick way to get a sense of a batter's quality.
The formula for OPS+ is OPS+ = 100*((OBP/lgOBP)+(SLG/lgSLG) -1), whith lgOBP and lgSLG representing the league average for that statistic in that year.
