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.
"He has worked so hard over the past three years to come back but his shoulder just wouldn't allow it to happen," Montana said in an email. "He's a first class guy with a great family that he'll get to spend more time with now."
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 for the Diamondbacks, using his heavy sinker to win a Cy Young and earn three All-Star selections. He finished second in the Cy Young voting in both 2007 and '08, winning a total of 40 games those seasons.
Webb threw four innings with the Diamondbacks in 2009, leaving his first start of the season with an aching shoulder and missing the rest of the season. In 2011, he signed with the Texas Rangers, but never pitched in a regular-season game.
