Baseball stats school: lesson 1
How is a .269 hitter just as effective as a .350 hitter
and Mike Cameron kicks ass
As we all know, Ichiro was an absolute phenomenon last year, coming from Japan ball to only lead the AL in batting average, and he's one of those players, with his sheer athleticism, that pegs the "intangibles" meter. Nothing I say in this rant is meant to take ANYTHING away from his god-like baseball prowess. BUT....
BA (batting average) is severely over-rated. ESPN has developed a great stat, which I believe is a as good a measure of a players at-the-plate productivity as any single number can be: The OPS. It's simple, add a player's On Base Percentage to his Slugging Percentage (SLG) and get his OPS (On Base % Plus Slugging %). I'll save you the nuances of these numbers, but click here for a simple explanation)
And here we go. Click here for the 2001 Regular season batting numbers, and come to your own conclusions.
And if you follow my reasoning, and see Mike Cameron has a OPS a mere .006 less than Ichiro, and you see that for many practical purposes, Cameron was essentially just as effective with a bat as 2001 AL MVP Ichiro, and you also understand that Cameron won a Gold Glove -- as well as Ichiro -- and you just begin to understand: a) how good Cameron is; and b) how it is the Mariners could win 116 games last year (can you say "mind-bogglingly good defense").
So, lets look at AL centerfielders, who played in a majority of their teams games last year, on ESPN's sortable fielding stats.
The stat explanations are at the bottom of the page, as well as qualification standards. I think "Fielding %" is a little misleading, especially when Mike Cameron is 8th on this list, but only .012 (1 in 83.3 -- over a 162 game season) "worse" than the best in the AL, so I have chosen Range Factor, and it is also good to look at "Zone Rating."
Anyhow, lets cross-reference those ratings with these players OPS's: here's 2001 AL OPS ratings
Bernie Williams: 917
Carlos Beltran: 876
Jose Cruz: 857
Mike Cameron: 832
these represent the top offensive every-day center-fielders in the AL.
Now how do we quantify defensive prowess? And how important is defense to the quality of a centerfielder? Well, in this man's humble opinion, the rankings of "defensive importance" to the eight positions (excluding pitcher) are as follows:
1) catcher
2) shortstop
3) 2nd base
4 Centerfielder
so defense is very important to centerfielder rankings. much more important than, say, a first baseman, or even left fielder (two traditional dumping grounds for one-dimensional players).
Now, I remind you Cameron won a Gold Glove last year, and looking at the fielding stats, I'd say he rates pretty favorably defensively with all three of the AL CF's ahead of him on the OPS chart. And to mitigate the OPS standing: Cameron led AL CF's in RBI (110); was 3rd in runs (106 for Beltran, 102 for Williams, 99 for Cameron); and led in stolen bases (6th in the AL, w/ 2 more than Cruz).
Okay, I'm rambling, put here's the point behind all these numbers: Cameron was rated as one of the top three outfielders in defense last year (judged by his Gold Glove) and was a offensivley productive as any other AL centerfielder. That has ME saying "Ken Griffey WHO???
Don't get me wrong, folks, I'd be willing to take him back... go ahead and stick him in left.
