PHOENIX - Diamondbacks ace Brandon Webb threw off the mound on Tuesday for the first time since undergoing right shoulder surgery.
Webb said he was pleased with how he felt after throwing between 20 and 25 pitches in the Chase Field bullpen.
Webb made one start last year, on opening day, then underwent surgery on Aug. 4. The club exercised an $8.5 million option for 2010 in hopes that the former NL Cy Young Award winner would return to dominance.
"I'm right where I expected to be," Webb said in a statement. "Having not been on the mound in a year, I am pleased with how I felt."
It's not clear when Webb, who turns 31 in May, will throw again. The club has not released a timetable for his return to the rotation.
Webb had been a stalwart of the Arizona staff, pitching at least 200 innings every year from 2004 to 2008. He won the 2006 NL Cy Young Award and finished second in 2007 and 2008.
Webb is 87-62 with a 3.27 ERA in seven seasons.
"It was good to get him into the next phase of his rehabilitation," manager A.J. Hinch said. "He looked comfortable. This is a positive sign as we're getting close to spring training."
• Left-hander Mark Hendrickson agreed Tuesday to a one-year contract with the Orioles that guarantees him $1.4 million after pitching well out of Baltimore's bullpen last season.
The 35-year-old Hendrickson went 6-5 with a 4.37 ERA in 53 games with Baltimore last year. He was most effective in relief, going 4-0 with a 3.44 ERA.
• Speedy outfielder Willy Taveras has been released by the Oakland Athletics, eight days after he was acquired from Cincinnati with infielder Adam Rosales for infielder Aaron Miles and a player to be named.
Taveras had been designated for assignment immediately following the Feb. 1 trade. The A's owe his $4 million salary in the final season of a $6.25 million, two-year contract that he signed with the Reds.
• Yorvit Torrealba and the Padres have finalized a one-year contract that guarantees the catcher $1.25 million. He figures to share playing time with ex-Wildcat Nick Hundley, who started 71 games last year and hit .238 with eight homers and 30 RBIs.
• Astros reliever Brandon Lyon had surgery to drain a small cyst in his pitching shoulder but is expected to be ready for spring training. The team said in a statement Tuesday that Lyon had the cyst drained two weeks ago and has been throwing without discomfort since.
• Left-hander Scott Schoeneweis has agreed to a minor-league contract with the Brewers and was invited to spring training.
• Jacque Jones has returned to the Twins, agreeing to a minor-league contract. Jones began his major-league career with Minnesota in 1999. The outfielder's best season was 2002, when he hit .300 with 27 homers and 85 RBIs while the Twins advanced to the AL championship series.
