Comments on: WAR Data: Best Catcher Seasons Since 2000 http://www.baseball-reference.com/blog/archives/6302 This and that about baseball stats. Tue, 16 Jul 2013 17:01:55 +0000 hourly 1 https://wordpress.org/?v=4.6 By: Johnny Twisto http://www.baseball-reference.com/blog/archives/6302/comment-page-1#comment-21469 Tue, 25 May 2010 16:58:07 +0000 http://www.baseball-reference.com/blog/?p=6302#comment-21469 Lawrence, my guess is that it's partly because those guys caught a few less games each season than more recent guys do. And also their "Rpos," which is the number of runs added for playing a tough position, appears to be less than in recent times. I'm not sure why that is; maybe because there were a lot of good catchers at the time so the position was seen as stronger overall?

Nat, it comes from baseballprojection.com. I gotta say, I don't understand his rating of Mauer's '08. If Mauer's '08 hitting was 45 runs above average, how can his '09 be only 57 runs above average? B-R shows adjusted batting runs, which also agrees that Mauer 09 was 57 runs above average, but Mauer 08 at 32. That difference makes more sense, considering he was more than 30 points of OBP and more than 130 pts of SLG better in 09.

DavidRF, is there some sort of bias against pre-WWII catchers?? I do not see Mickey Cochrane, Bill Dickey or Gabby Hartnett listed (I looked them up to check). I just find it hard to believe that ALL the greatest seasons by a catcher happened after 1950...

This goes to show that there is not always agreement between different calculations of WAR. Where does the BBref WAR data come from?

WAR has components for fielding. I'm not sure how its done... and from what little I know catcher-fielding is especially hard to quantify.

Its in there though. You can check the old Piazza vs. Rodriguez debate as a sanity check. It says that Piazza cost his teams 70 runs over his career while Rodriguez saved 154. That's about a 22 WAR swing between the two players. The two Piazza seasons above didn't quantify that badly somehow. I can't explain why just looking at the SB/CS data. There must be other stuff in the mix as well. And of course, Piazza could really hit.

Pretty good company for Mauer... and a couple of surprises on the list as well.

Neil, I don't believe that WAR's positional replacement levels are based on single-season performance. (Even if they were, a 9-point change in OPS wouldn't make that much difference.) I think WAR sets the "Rpos" (positional scarcity) on a decade-by-decade basis. The other major thing is that Mauer played more than 30 games at DH last year.

He lost 7 Runs above average due to these factors which is the entire difference between the 2 seasons. The problem with the whole definition of "replacement level" is why I cannot buy into WAR. For example, in 2009 the Yankees had 54.3 wins - WAR, but the Twins had 52.3 wins - WAR, so I guess a team of replacement players for the Yankees are better than a team of replacement players for the Twins, yet they are supposed to be the players.
