Weighted Runs Created Plus (wRC+)

wRC+ takes the statistic Runs Created and adjusts that number to account for important external factors — like ballpark or era. It’s adjusted, so a wRC+ of 100 is league average and 150 would be 50 percent above league average.

If you play your home games for the Rockies at Coors Field then it will produce a lower wRC+ than if you play at many others stadiums that are pitcher friendly.

The formula
(((wRAA per PA + league runs per PA) + (league runs per PA – ballpark factor x league runs per PA) / league wRC per plate appearance, not including pitchers)) x 100.

Weighted Runs Created Plus- Why Use it?


Because it is a great comparison tool. It is similar to WAR and RBI in that it is a counting statistic that grows over the length of a baseball season. It is not helpful to pay attention to this number except after a season is complete. But if a player is hurt or misses some games it doesn’t penalize them for that.

Upon closer examination, it grabs a player’s wOBA and adds it with what the league average player is expected to have per plate appearance and throws that into the mix with different ballparks. This gives us a number which is multiplied by 100. The scale is listed below:

Again this is not a projection tat but rather a look at the end product for assessment of a player and his complete season.
