Next man up. We're paying for the excellent health we had in the starting pitching last year now. Hopefully these are rather minor injuries and we can get them out of the way early in the season (and it takes innings off of them for the post season).
Too bad Forrest Whitley has been terrible recently. He'd probably have his chance. J.P. France may be the best option.
I thought so too, however: .216 with a .632 OPS vs current Astros .237 with a .717 overall I know he's had a few big hits against us, I guess that's why he stands out
