NEW YORK -- David Huff was back on the mound Monday morning, less than 48 hours after an Alex Rodriguez line drive struck the left-hander in the head and sent him to the hospital.

Huff threw a bullpen session before the series finale at Yankee Stadium. Manager Manny Acta called it the "first step" in determining whether Huff will make his next scheduled start, Thursday at Detroit's Comerica Park, and all indications are that Huff will get the ball that day.

"He had no aftermath feeling or anything like that," Acta said. "He's on target, unless he shows up [feeling] something different."

Huff said he couldn't feel better. He has had no dizziness or headaches in the wake of the blow to the head, and he hopes to make Thursday's start.

"I threw the bullpen I usually throw," he said. "I didn't take time off or throw less pitches. It was a good feeling."

The Indians will continue to evaluate Huff's medical condition to ensure he is not showing any concussive symptoms. Head athletic trainer Lonnie Soloff said the Tribe will "err on the side of caution" in the determination. But Huff never lost consciousness, has shown no signs of memory loss and did not suffer any brain damage or bleeding as a result of the ball striking his head, just above the left ear.

Huff (2-6, 5.54 ERA) said he is not concerned about feeling fearful of another line drive the next time he takes the mound in a game situation.

"I'm fine, I feel fine and hopefully I'll bounce back," he said. "I'm going to try not to think about it."

Slumping Choo gets first day off

NEW YORK -- There was a strange sight on the Indians' lineup card Monday. Shin-Soo Choo was listed as an available bat off the bench, not the starting right fielder.

For the first time in 2010, Choo was given a day off by manager Manny Acta. And the timing certainly seemed about right, as Choo was mired in an 0-for-17 funk. The Yankees started left-hander Andy Pettitte, so Choo was given a break against a fellow southpaw.

"He deserves one," Acta said. "He's a guy who wants to be out there every day, but he deserves the chance to clear his mind and reload."

Aside from Choo's 0-for-4 performance Sunday, Acta felt Choo, whose average has dropped to .280, hit the ball hard the first two games of this series.

"Just right at people," Acta said. "He came back to the dugout and asked if he should hit the ball softer. He's handled it well. He's been in a good mood. He's hit the ball hard, and that's what we want to see. It's not like he's been overmatched at the plate and been getting jammed."

Hagadone promoted to Double-A Akron

NEW YORK -- The Indians have a lot to like about prospect Nick Hagadone. He's 6-foot-5, 230 pounds, has a fastball in the upper 90s and is left-handed.

And Hagadone, acquired in last summer's Victor Martinez trade with the Red Sox, is climbing the Minor League ladder. He has been promoted to Double-A Akron, where he'll get the starting nod Tuesday against Erie.

"Obviously, he's a big part of what we're trying to accomplish here," manager Manny Acta said. "You keep an eye on a guy like that."

Hagadone, 24, was 1-3 with a 2.39 ERA in 10 starts for Class A Kinston. He struck out 45 and walked 29 in 37 2/3 innings, holding opponents to a .206 batting average. He tossed five scoreless innings against Potomac in his previous start.

The Indians have to be careful with Hagadone's innings pitched this season. He was limited to 45 innings at the Class A level last season, following reconstructive elbow surgery in June 2008.

Worth noting

Manager Manny Acta liked what he saw from Lou Marson, Jason Donald and Trevor Crowe over the weekend. "I feel like this series has helped them grow a little bit," Acta said. "That's something positive we'll take out of it, regardless of the wins and losses." ...
