Dude, I know what your point is. If you want to point out that Lester's k/9 in 2008 wasn't exactly stellar, just say so.
My point is a legitimate response to yours, so get off your high horse.
Fenway is a terrible park to hit homers in. It is slightly less terrible for righties, but the part you're ignoring that I've pointed out repeatedly is that it's a bigger piece of a MUCH smaller pie. There just aren't a lot of long ones hit here compared to the league average, especially considering both the quality of our own lineup and the fact that we face the Yankees so often.
On the other hand, once again, Fenway is quite a good ballpark for overall righthanded power and average -- because of the short, and also very high, wall. But not because of home runs.
The fact is that the short wall in left is also a very high wall in left. There's plentty of righthanded power bonus, but no, it is not that easy for a righthander to homer in Fenway. Maybe easier than for a lefthander at the same park, but not easy compared to the rest of the league.
