CLEARWATER, Fla. -- Roy Halladay didn't feel well, and it had little to do with his pitching.

The two-time Cy Young Award winner left after one inning Sunday, forced out of the Philadelphia Phillies' 5-3 win over a Baltimore Orioles' split squad because of a stomach virus.

Halladay allowed one hit and a walk. He was sweating profusely when he was pitching and at one point bent over behind the mound.

"He was throwing up a little bit," Philadelphia manager Charlie Manuel said. "He threw up after he came out after the first inning. He was sick before (the game), but he's hardheaded. He wanted to pitch, and he threw up and we took him out of the game."

Halladay, who did not speak with reporters, was roughed up in his previous start and said he felt "lethargic" afterward. He insisted he had no injury. Halladay missed almost two months last year with a shoulder problem.

Phillies catcher Erik Kratz, who caught Halladay both times this week, said his batterymate looked good in the abbreviated outing, aside from the sickness.

"He was executing his pitches," Kratz said. "His cutter was cutting. His sinker was sinking, and he was throwing them on the corners. For him, that's huge. I don't have any idea what his velocity was, and that's neither here nor there, because when he's on, he's locating his pitches. And he was able to do that."

The 35-year-old Halladay went 11-8 with a 4.49 ERA in 25 starts last year. He entered spring training confident he had overcome the lower back and shoulder issues that began to plague him last spring. Although his progress has been slowed this week, Halladay could pitch up to three more times in exhibitions.

Zach Miner took over for Halladay in the second inning and allowed one run and four hits in two innings. Freddy Galvis hit a two-run homer for the Phillies -- homering on St. Patrick's Day for the third straight year.

Baltimore's Jason Hammel allowed four runs and six hits in 4 2-3 innings.
