These averages are defined as: formula_2 and formula_3 where: Rewriting the expression to account for the different denominators yields the final expression title: Baseball statistics text: 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). The statistic wOBA (weighted on-base average) attempts to correct for this. OPS is also useful when determining a pitcher's level of success. "Opponent On-base Plus Slugging" (OOPS) is becoming title: Batting average (baseball) text: causing it to have little predictive value. Batting average does not take into account walks or power, whereas other statistics such as on-base percentage and slugging percentage have been specifically designed to measure such concepts. Adding these statistics together form a player's On-base plus slugging or "OPS". This is commonly seen as a much better, though not perfect, indicator of a player's overall batting ability as it is a measure of hitting for average, hitting for power and drawing bases on balls. In 1887, Major League Baseball counted bases on balls as hits. This skyrocketed batting averages, including some near title: On-base percentage text: increase when the batter reaches base due to fielding error, fielder's choice, dropped/uncaught third strike, fielder's obstruction, or catcher's interference. On-base percentage is added to slugging average to determine on-base plus slugging (OPS). The on-base percentage of all batters faced by one pitcher or team is referred to as on-base against. Traditionally, players with the best on-base percentages bat as leadoff hitter, unless they are power hitters, who traditionally bat slightly lower in the batting order. The league average for on-base percentage in Major League Baseball has varied considerably over time; at its peak in the late 1990s, it was
