Mueller at 2B? Why? Millar batting 6th, ahead of Nixon and Varitek? I know Varitek's slumping, but he's still better than Millar. That also leaves us with a bench of Kapler, McCarty, Pokey, Mirabelli, and Bellhorn. We could pinch run or have defensive substitutions, but no solid pinch hitting (not a big market for pinch walking). That's kinda scary.
My suggestion:
1) Damon CF
2) Bellhorn 2B
3) Ortiz DH
4) Manny LF
5) Nixon RF
6) Nomar SS
7) Varitek C
8) Mueller 3B
9) Millar 1B
Flip Trot/Nomar as you see fit, but I get annoyed with having 1-pitch outs too high in the order. I'm also not sold on Nomar getting his power back. Millar is easily the worst hitter in this lineup (could argue Bellhorn, but only by ignoring OBP), so I want him 9th. This also leaves a bench of Kapler, McCarty, Pokey, Youkilis, and Mirabelli. Gives the bench defensive options (Pokey, Kapler, McCarty), running options (Pokey, Kapler if desperate), and more than one solid pinch hitter (Youk, Mirabelli).
