This is what I would do...
1. Dump Chipper for Betemit/Quinlan platoon.
2. Grab Griffey, dump Tavares.
3. Since Jeter can lead off for you vs. RH's, grab E. Young to DH for you and lead off vs. LH's.
4. Grab Mauer if you can, dump Miller. Either keep Pratt and platoon him or grab Greene for the same reason. (I'd prefer Greene)
If this works out, you would have Mauer, Griff and Abreu plus Betemit to combat the RH's.
Betemit hit .345 for me in Fenway with a .392 OB. Mainly because he saw alot of RH's and because he's not park dependant.
I'd try to keep Turnbow.
