Nice start for the Astros tonight - Pettitte has cruied through 3 innings, and our offense is showing signs of life:

Top 1

Taveras flies out.
Biggio singles. (Should have been called out at 1st - close play though)
Bagwell walks (Biggio steals 2nd on a 3-0 pitch)
Lamb singles, Biggio scores.
Lane flies out to deep center, Bagwell to 3rd, Lamb to 2nd.
Ensberg doubles to LF on a 3-2 pitch, Bagwell and Lamb score.
Everett grounds out

We haven't done much since then, but that's a pretty good start to a game. If Lamb keeps swinging the bat this well it's going to be tough to sit him when Lance comes back. But who do you sit out of Ensberg / Lane / Bagwell? I guess give any of them the occasional day off, and clearly Lamb would be the top pinch hitter off the bench.
