Actually, this is a much better doubles park than it is a HR park. In fact Fenway is consistently THE doubles park. That wall may be shallow, but you lose a lot of the benefit of that from a HR perspective by having it be freaking 100 feet tall. On the other hand, it's a great park for line drive hitters, and the more contact and more line drives, the better.
That's why a guy like Mike Lowell, who hits a lot of line drives, hits for a high average, but isn't a huge HR hitter, thrives here -- while guys like Wily Mo Pena or Jeremy Giambi who are dependent on the long bomb, tend to struggle a bit.
Also it's a testament to just how awesome Big Papi really was that he hit all those HR's here in his prime, even with the park factors... well... factored in.
What that means in real terms is that Derek Jeter would have probably been about the best Fenway hitter in the history of ever. It's why Youkilis has thrived here, and ditto for Pedroia -- they're the kind of hitter that will do well here. Guys like Beltre, or Adrian Gonzalez -- or, yes, Adam LaRoche -- will probably NOT perform up to their averages here, because they're dependent on something that isn't easy to hit.
And, ironically enough given our team's history, we might have one of the best parks ever to put a speedy fast lineup into, one that can score from first on a double consistently.
