Heading into Wednesday's game, Troy Tulowitzki leads all qualified hitters in batting average (.354), on-base percentage (.447) and slugging percentage (.634). We can call that the triple-slash Triple Crown. And if you're doing that, you're the best hitter in the game. (Jerry Crasnick has a story here on the game's best pure hitters worth checking out.)
Except ... of course, Coors Field. But we can adjust for the advantage that Tulo and all Rockies hitters possess, by park-adjusting their stats. FanGraphs has a rate stat called wRC+, which adjusts for home-park environment. Tulo is first in the majors, just ahead of Mike Trout, Giancarlo Stanton and Andrew McCutchen.
And yet, I'm still bothered by these facts:
--Tulowitzki is 92nd in the majors in road batting average (.252).
--He's 39th in road OBP (.355).
What Tulowitzki has done is destroy pitchers at home: .457/.539/.803, with 11 of his 18 home runs and 22 of his 34 extra-base hits, in the same number of plate appearances. That said, Tulo does appear to be an improved hitter this season; he's always struck out more than he walked, except in his shortened 47-game 2012 season, but this year he has 42 walks and 43 strikeouts. Back in May, Richard Bergstrom of the RockiesZingers site pointed out that Tulowitzki has changed his stance a bit this year. His BABIP (average on balls in play) is .365, well above his career mark of .320, and according to Baseball-Reference.com, his line-drive rate the past two years has increased dramatically over his career norms (30 percent last year and 28 percent this year, compared to 21 percent over his career).
Still, those road numbers don't scream "best hitter in baseball." There are various factors in play there, however. The Rockies do play in a division with three pitcher's parks in San Francisco, Los Angeles and San Diego, so that's going to hurt his road stats. There appears to be a Coors Field side effect that hurts Rockies hitters when they go on the road. All of that makes it difficult to evaluate Rockies hitters. In other words, what would Tulowitzki do on another team? That's the unknown.
One thing I've wondered: Are good hitters able to take a bigger advantage of Coors Field than their less talented teammates? When adjusting for Coors, a generic park effect is established, based on the results of all Rockies hitters.
As a team, the Rockies are hitting .328/.377/.529 at home and .237/.290/.387 on the road. Using another advanced metric called weighted On-Base Average (wOBA), the Rockies have a .384 wOBA at home and .291 on the road, a difference of 93 points. Tulo's spread is 203 points, so he's been much better at home even compared to his teammates.
What about recent years? Between 2009 and 2013, the Rockies had a .356 wOBA at home and .295 on the road, a difference of 61 points. Over those seasons, Tulowitzki had a .412 wOBA at home and .368 on the road, a difference of 44 points. So before this year, he didn't improve at Coors as much as his teammates.
So far, however, in 2014 Coors has been a better run-scoring environment than its recent past. That could change as the season evolves. Different sites will come up with different park factors but most use a multi-season park factor. FanGraphs appears to use a five-year factor, so the fact that Coors has been even more extreme than normal in 2014 won't "penalize" Tulowitzki as much.
Back to the question at hand: Is Tulowitzki the best hitter in the game? I'm still skeptical, even if an altered stance (and good health) has led to better numbers. Even his home numbers are skewed by his hot start: He hit .608 in his first 15 home games but .355 since. I guess I'd like to see what kind of numbers Miguel Cabrera or Mike Trout would put up in Colorado before declaring Tulo the best in the game. Or Giancarlo Stanton. How many more home runs would he hit if he got to play there?
What do you think? Who is the game's best hitter right now?
