Warming up to start the third, Houston starter J.A. Happ felt a twinge in his right side.
Happ pitched through the inning, retiring the side in order before leaving the game before the fourth.
Happ suffered a strained right oblique that throws into question whether he’ll be able to start Sunday in Philadelphia.
“I’m sort of delirious with frustration right now,” Happ said.
Happ went 6-4 with a 3.40 ERA last season,, splitting time between Philadelphia and Houston.
The 28-year-old suffered an intercostal strain in 2009 which kept him out three weeks.
“I don’t plan on doing that again,” Happ said. “My goal is still to start Sunday but my body, it’ll tell me.”
Happ said he held back in the third after feeling the initial pull before it tightened up between innings.
“I was being tentative,” Happ said. “It’s on my right side so it’s kind of where your strength is. I wasn’t pushing it too hard there. I got through that inning. I just think it’s a good thing I came out at that point without doing more damage to it.”
Happ, who was acquired in the deal last year that sent Roy Oswalt to Philadelphia, said the chilly weather wasn’t too blame.
“I don’t think that was a factor,” he said.
