I do understand the concern - but...
The Sox have an outrageously good lineup vs LHP, with Pedrioa, Victorino, Gomes, Middlebrooks, Napoli, and Ross.
And these guys hit him well too -
Pedroia: 9/40 (.225, not good), but he's got 4 2B,
Victorino: 5/9, 1 HR
Gomes: 8/22 (.364 average), 1 HR, 7 RBI
WMB: No Appearances
Napoli: 6/12 (.500), 1 2B
Ross: 4/12, 1 2B, 1 3B
Others:
Ellsbury is 8/20 against him
Bradley and Iglesias obviously have no appearances.
Either way, the guys we have in our lineup tonight have some good success against Pettitte.
