AP - Brandon Webb, who won the NL Cy Young Award in 2006 and was one of the top pitchers in baseball before being beset by arm injuries, is retiring.

The right-hander's agents, Mike Montana and Jonathan Maurer of Millennium Sports Management, confirmed Monday night that Webb was calling it a career.

The 33-year-old Webb hasn't pitched in the majors since 2009 because of shoulder problems. He came up with Arizona in 2003 and had a 2.84 ERA in 180 innings. He pitched more than 200 innings each of the next five seasons, using his heavy sinker to win a Cy Young and earn three All-Star selections.

He threw four innings with the Diamondbacks in 2009. In 2011, he signed with the Texas Rangers, but never pitched in a regular-season game.
