KISSIMMEE, Fla. -- Right-hander Alberto Arias left the Astros' game against the Yankees in Tampa on Saturday with a bruised right hand after being hit by a Hideki Matsui line drive. Arias will have X-rays taken to determine the severity of the damage.

Arias, a bullpen candidate, had not given up an earned run in five spring appearances this year. He yielded an unearned run to the Yankees on Saturday, allowing one hit over 1 1/3 innings with three strikeouts.

Arias surmised he would have the X-rays taken on Sunday.

"I feel a little pain," Arias said. "They think it's going to hurt a lot, but they don't think it's broken."

The Astros' schedule called for split-squad action on Saturday, with half the club traveling to Tampa, Fla., to play the Yankees and the other half staying behind to host the Phillies.

Left-hander Wandy Rodriguez started the game in Tampa, his first outing since straining a muscle on his left side during his first start in February. Rodriguez pitched two innings, allowed one run -- a solo homer -- on two hits with one strikeout. He threw 33 pitches, 25 for strikes.

Rodriguez also threw an additional 15 pitches in the bullpen. "I feel excellent," he said. "missed on location a couple of times, but I just need to pitch more to fix it. My arm felt really strong today."

Chris Sampson, who underwent offseason right elbow surgery, made his spring debut against the Yankees, allowing one hit over one inning, totaling 13 pitches.

"It was definitely good to be back," he said. "Now I can prove to the organization and to myself that I can let it go and all that [injury] is behind me now. I was pain-free and that's the most important thing."
