MLB Pseudo-Season 2020: Roger, Dodgers

Serious question for our resident SABRmetricians. What is Weighted Runs Created Plus?

Basically, it provides weighting and quantification that takes into account various macro factors such as park effects, the era the player has played in (say, measuring a deadball-era hitter to one after the mound was lowered after the Dodgers were breaking baseball in the '60s). Much like OPS+ and ERA+, it's normalized, so a stat of 100 is precisely league average in that particular year. But to take park effects into account, for example, let's say a guy socks 40 dingers while playing half his games at Safeco Field, where fly balls go to die, and then another guy hits 40 while playing at a launching pad like Coors Field. The guy playing in Seattle is going to have a higher wRC+, because of the weighting.

I think I've got it but how does the park figure in? Does it take into account crappy or excellent pitching?

No, because wRC+ is simply measuring runs actually created. ERA+ can be used, in conjunction, to factor in pitching quality.

The park effect is a simple formula:
Ballpark factor, at its most basic, takes the runs scored by Team X (and its competitors) in Team X's home ballpark and divides the figure by the runs scored by Team X and its competitors in Team X's road contests. Often times, that number will be ever-so-slightly adjusted if a team doesn't play the same opponents at home as on the road.

For example: In 2018, 849 runs were scored at Coors Field, and 676 runs were scored in Rockies games away from Coors Field. Coors Field had a park factor of 1.271, when looking at runs scored.

Another example is 1999, when Greg Maddux had a relatively poor season (by his meteoric standards), and it turned out that for that particular season, Turner Field turned into a rocket launching pad.

There is no one be-all, end-all advanced statistic. They all blend together to form a more coherent depiction of a player's qualities and a team's qualities.

CANCEL THE FUCKING SEASON YOU STUPID FUCKS
If they were to dump the season, I trust they'll dismantle all of Rob's fucked up rule changes. In particular, the magic double and the three hitter rules have to go. Those rules actually mess with the way teams play the game. With the magic double, one team may have the top of their order up with a man on second and others may only have the bottom of the order coming up. The three hitter rule deprives managers of tactical and strategic options. As a traditionalist, I have only recently come to accept the DH. All this new crap is frying my brain. The 7-inning double header may end up being okay. We'll have to see.
