The heart of the order needs to show the bottom of the order it can score, too. A 2-run lead is nice, but 3-4+ would be better. Don't make us sweat those last six outs.
Nice inning by Nerris against the bottom of the Yankees order. 2-3-4 up for the Astros. Time for a few insurance runs.
The other thing about this series with 7 games in 8 days, is that pitch counts for relivers matters almost more than pitch counts for starters.
