I'm not sure how much I like Crawford in the #3 spot. I didn't love that it was common knowledge that he would hit 3rd. Never made much sense.
After he was initially signed I proposed (along with a few others here) the idea of having him hit #2 with Pedroia hitting 3rd, and I think I'm still in favor of that idea:
Ellsbury
Crawford
Pedroia
Gonzalez
Youkilis
Ortiz
Drew/Cameron
Salty
Scutaro
It just seems like the #3 hitter's job in this lineup should be to drive the ball and be a really tough out, especially with such tremendous hitters behind him. That's Pedroia, not Crawford. Crawford can give up outs, put pressure on the defense, as a lefty he can move Ellsbury over if he's at 2nd by pulling the ball, rather than hitting it the other way. He won't hit into double plays and he should be able to be aggressive on the basepaths with Pedroia at the plate. Seems like there's a lot of good reasons.
To me, Ellsbury seems to be a much better hitter than he was when he first came up. All through ST, in today's game, and even at the end of the 2009 season he was getting beat by fewer fastballs, able to foul pitches off, responding well to offspeed stuff, etc., I think that he and Crawford could more than hold their own against a LHP brought in to face them.
What do others think? Pedroia and Crawford are both pretty ideal #2 hitters, but to me Pedroia is the better #3 hitter of the two.
