This week I’ve been playing around with some pitching stats and this just blew me away: Rockies RHP Aaron Cook has an ERA/WHIP/BAA of 4.26/1.56/.297 on the road… but 2.33/.88/.215 at home! That defies all conventional logic with Coors being on of the biggest hitter-friendly parks in Major League Baseball.

So for Cook, he is pitching much better in one of the best hitter’s parks than elsewhere. What gives? I just can’t figure this one out… the law of averages would suggest that since Colorado batters are hitting thirteen points higher at home than on the road… then opposing hitters should be doing similarly? But they aren’t… Colorado pitchers, as an entire staff, have a lower ERA/WHIP/BAA line at home of 4.74/1.41/.274; compare that to the road line of 5.18/1.59/.275. I’d say that this is the humidor at work… but it still doesn’t explain why the Rocks hitters are not subject to the same laws of physics as their opponents…
