Hunter Pence returns to the lineup for the Astros after being given a day off to "clear his head." Pence is hitting just .180 this year without a homerun. Pence was widely considered the leading rookie of the year candidate last year until Ryan Braun of the Brewers went off.
Brad Ausmus will catch Shawn Chacon tonight. JR Towles had been doing most of the catching, but Ausmus will return to the lineup tonight. Ausmus is hitting just .200 this year. The 'Stros catcher is just 1-8 against Adam Eaton all time.
One last note, ESPN's accu-score has the Philies as 60% favorites. Take that for what it's worth. Thought I would mention it.
