Offense

  • OPS+ – All this is is a standardized version of OPS (on-base plus slugging percentage). 100 is league-average, above is better, below is worse. Mike Trout led the league last year with a 187 OPS+; Rhys Hoskins finished his breakout rookie campaign with a 163 OPS+.
  • Weighted On-Base Average (wOBA) – Like OPS, wOBA attempts to measure a player’s overall effectiveness at the plate. wOBA favors getting on base while OPS favors hitting for extra bases. According to Fangraphs, an average player will have a .320 wOBA, while a great one will have a .400 wOBA. Trout also led the league with a .437 wOBA last year, while Andrew Knapp had a .321 wOBA.
  • Weighted Runs Created (wRC) – wRC is based off wOBA and measures a player’s offensive values in terms of runs. For example, Odubel Herrera was worth 72 weighted runs created last year. wRC+ is the standardized version of wRC, like OPS+ and OPS. Herrera had a 100 wRC+ last year.
  • Weighted Runs Above Average (wRAA) – This stat is also derived from wOBA and indicates how much better or worse a player is compared to the league average. Cincinnati’s Joey Votto was the most valuable player offensively according to wRAA at 64, meaning he was worth 64 runs more than the average major-leaguer over the course of the season.
  • Batted Ball Data – This is a broad category as it accounts for where players hit the ball, how hard they hit it, and how long the ball is in the air. The Phillies lean on this heavily to determine where to position their fielders for defensive shifts.
