## wRC+

*Weighted Runs Created (wRC) is an improved version of Bill James’ Runs Created (RC) statistic, which attempted to quantify a player’s total offensive value and measure it by runs. In Runs Created, instead of looking at a player’s line and listing out all the details (e.g. 23 2B, 15 HR, 55 BB, 110 K, 19 SB, 5 CS), the information is synthesized into one metric in order to say, “Player X was worth 24 runs to his team last year.” While the idea was sound, James’ formula has since been superseded by Tom Tango’s wRC , which is based off Weighted On-Base Average (wOBA).*

*If wRC sounds similar to Weighted Runs Above Average (wRAA) or Batting Runs, that’s a good thing. wRAA is simply wRC with league average scaled to zero, while Batting Runs is the park and league adjusted version of wRAA.*

*Similar to OPS+, Weighted Runs Created Plus (wRC+) measures how a player’s wRC compares with league average after controlling for park effects. League average for position players is 100, and every point above 100 is a percentage point above league average. For example, a 125 wRC+ means a player created 25% more runs than a league average hitter would have in the same number of plate appearances. Similarly, every point below 100 is a percentage point below league average, so a 80 wRC+ means a player created 20% fewer runs than league average.*

*wRC+ is park and league-adjusted, allowing one to to compare players who played in different years, parks, and leagues. Want to know how Ted Williams compares with Albert Pujols in terms of offensive abilities? This is your statistic. wRC+ is the most comprehensive rate statistic used to measure hitting performance because it takes into account the varying weights of each offensive action and then adjusts them for the park and league context in which they took place. **(Text, stats courtesy of Fangraphs).*

Key: Bolded players are currently in majors

It's June 23. The San Francisco Giants are 75 games into a dreadful season where they've won just 27 games. Mark Melancon, the closer who the Giants inked for 62 million dollars in the offseason, has appeared in just 31.7 percent of games in which he was on the active roster...
