Red Sox pitchers (Schilling, Beckett, Wakefield, Clement, Lester, Papelbon, Hansen, Delcarmen, Timlin, Tavarez, Seanez) vs. the NL, in 142.2 IP:
16-1, 3.15 ERA, 0.93 K/9IP
Pedro, Lowe, and Arroyo all have worse numbers than these against the NL. Sanchez has a better ERA (2.44), but his other numbers are worse.
Now: Pedro/Lowe/Arroyo/Sanchez vs. the AL, in 69 IP:
3-4, 5.22 ERA, 0.71 K/9IP
Whoop-dee-doo. Sure sucks we got rid of them.
[Interesting side note: all those interleague games really inflated Red Sox pitchers' stats. Taking out games against the NL, Beckett's, Delcarmen's, Timlin's and Hansen's ERAs jump up about 0.4; Lester's jumps up 0.7, to 5.46. Yikes.]
