Mike Adams happy with first 'pen session

SURPRISE, Ariz. -- Mike Adams threw off a mound for the first time on Tuesday and was pleased with how he felt. He threw 30 pitches that included both fastballs and changeups.

The 33-year-old reliever had surgery to repair a hernia in early January and figures he's "a week or two" behind the other pitchers as spring training begins.

"Most guys have been throwing off a mound before they get here and I just did it for the first time," Adams said. "But I'll be fully caught up by mid-March. I feel good. I just have to get the arm strength up."

Adams felt back painduring and after the season and had it checked out when it was discovered that it was a hernia. He doesn't feel any pain now and is focused on the 2012 season.

Adams was 2-3 with a 2.10 ERA in 27 games with the Rangers after he was traded from San Diego to Texas at the trade deadline. He gave up 11 hits (two of those homers) and six walks in 8 1/3 innings in the postseason and admitted that he was fighting fatigue. He wasn't happy with the way he pitched down the stretch and has resolved to improve this season.

"I know I can pitch better and that's my focus," Adams said.

While most of the staff will throw to live hitters this week, Adams will continue to build up arm strength.

"I'm not worried about being ready," Adams said. "I'll be caught up with them soon."
