After a rehab start Tuesday at Triple-A Oklahoma City, the Astros felt McHugh was ready to go, rather than start Brett Oberholtzer, who had been throwing in McHugh's place.
"It feels great," McHugh said. "It looks good, feels good."
Oberholtzer has been the odd man out of the Astros' rotation despite his strong pitching of late -- a 2-1 record and 3.00 ERA in six starts -- as he's bounced back and forth between the Minor and Major Leagues.
"Oberholtzer has done a tremendous job," Porter said. "He's been kind of the odd man out the last few times, and each time in which we've called him back up, he's performed at a level that would make you consider keeping him in the rotation. He hasn't done anything to hurt his chances of staying here."
Porter announced after Saturday's 7-3 loss that Oberholtzer will start Monday against the A's.
