All time, the Phils are 18-26 at the Astros' home, including dropping two of the first three games of this series.
Philadelphia's .409 winning percentage at Minute Maid is the team's third lowest at any of the current National League parks (minimum 10 games). They have only fared poorer at AT&T Park (18-27) and PNC Park (14-24).
"They play us tough here," manager Charlie Manuel said. "They show up and they play."
The Phils have been swept four times at Minute Maid Park (2002, '04, '05 and '09).
