The 'stros now lead the NL wild card race. They've won 6 games in a row and 17 games in a row at home.
Since the Astros lead, if they lose tomorrow to close the regular season and the Giants win, then they will play a one game playoff in San Fran.
Roger Clemens pitches tomorrow for the Astros on only 3 days rest. Manager Phil Garner decided he wanted to give it his best shot, so he's putting Clemens on the mound.
Personally I'd rather give Clemens the day off and save him for a possible onegame playoff.
