Page "Baseball statistics" Paragraph 7

Some sabermetric statistics have entered the mainstream baseball world that measure a batter's overall performance including On-base plus slugging, commonly referred to as OPS.

OPS adds the hitter's on base percentage ( number of times reached base by any means divided by total plate appearances ) to his slugging percentage ( total bases divided by at bats ).

Some argue that the OPS formula is flawed and that more weight should be shifted towards OBP ( on base percentage ).
