Thome giddy over first step at first base

CLEARWATER, Fla. -- Jim Thome could not wipe the smile from his face Sunday afternoon at Bright House Field.

He had just played five innings at first base in a Grapefruit League game against Baltimore, the first time he had played first in the big leagues since 2007 with the White Sox.

"The adrenaline was pretty awesome," said Thome, standing in front of his locker, wearing a red "Beast Mode" T-shirt. "I haven't had adrenaline like that in quite a while. Getting close to 600 [home runs]. But this was very, very good. Very good."

Thome had three putouts and was involved in a rundown play, but had no ground balls hit to him. Those might come next time. Phillies manager Charlie Manuel said Thome might play first base again Tuesday or Wednesday.

"It felt good to be back," Thome said. "The hard work we have been putting in the back field in what we're trying to accomplish here, moving forward with what we're trying to accomplish, it was great. And we have a lot more to do. By no means are we where we want to be. But we're headed in that direction. So hopefully we can continue the path, the program we've been on and keep it going.

"I think the main thing is my body has felt pretty good. That has been the big thing. I didn't really know going in how my body was going to feel as I got going. ... I played five innings today, so we've got more to do."

Sharp Halladay on track for Opening Day

CLEARWATER, Fla. -- Roy Halladay believes he is on course for Opening Day.

The Phillies' ace allowed seven hits, two runs, two walks and one home run while striking out nine in 6 1/3 innings Sunday in a 3-3 tie with the Orioles at Bright House Field. Halladay will have one abbreviated start before pitching in the 2012 opener on April 5 in Pittsburgh.

"Repetition-wise, it's getting better," Halladay said. "I feel like I can throw any of the pitches for strikes when I need to. I'll take that right now."

Said Phillies pitching coach Rich Dubee: "He's fine. He's missing certain pitches in certain areas that aren't clicked in yet. But arm-wise, stuff-wise, I thought he threw some exceptional front-door cutters to righties. His curveball was outstanding. His split was really good. Roy was fine."

Worth noting

• Third baseman Placido Polanco played Sunday for the first time since he sprained his left ring finger March 17. He went 1-for-2 with one RBI.

• Right-hander Jose Contreras allowed two hits, one run and struck out two in one inning. He is recovering from right elbow surgery and has a 19.29 ERA in just three appearances. "Jose is coming along fine," pitching coach Rich Dubee said. "I'm very pleased."

Dubee said Contreras still has a chance to be ready by Opening Day.

"Jose has been a real bright spot this camp," he said. "I'm not concerned about the runs. I like the way the ball is coming out of his hand."

• Left-hander Antonio Bastardo pitched for the first time since March 18. He blanked the Orioles for two-thirds of an inning. He had been out because of tightness in his left elbow, which the Phillies said came from dehydration. "I feel good," Bastardo said. "I should be fine for the season."
