KISSIMMEE, Fla. -- Several pitchers, including Roy Oswalt and Mike Hampton, threw batting practice to hitters for the first time on Thursday.

Oswalt said he probably threw at about 90 percent, up from the 70-75 percent more common for this early in the spring season.

"I felt better than usual for the first time out," Oswalt said. "I probably threw a little harder today, just because I'm ahead of schedule."

Hampton faced Miguel Tejada and Lance Berkman, both of whom offered positive feedback when the session was complete.

"For the first day, it was pretty nice," Tejada said. "The ball was moving good on the outside corner. He threw just on the outside corner today."

Added Berkman: "With Hampton, it doesn't matter, as long as he stays healthy. If he's healthy, he's going to be good. The ball was coming out of his hand nicely."

Hampton has resumed his regular routine that he was following prior to a health scare that necessitated a return trip to Houston. His batting practice session on Thursday was a positive sign that things are returning back to normal.

"I just threw some fastballs, trying to get comfortable," Hampton said. "I've thrown two days in a row twice, so I just have to make sure i get through it. I'm trying to catch up for the days I missed."

The list of pitchers who also threw live batting practice sessions included: Alberto Arias, Brandon Backe, Tim Byrdak, Gilbert De La Vara, Jeff Fulchino, Danny Graves, LaTroy Hawkins, Tyler Lumsden, Fernando Nieve, Wandy Rodriguez, Polin Trinidad and Wesley Wright.
