PHOENIX — Arizona Diamondbacks pitcher Brandon Webb has elected to have arthroscopic surgery for his right shoulder.

"We support his decision to have surgery," Diamondbacks executive vice president and general manager Josh Byrnes said. "Obviously, we exhausted every other course of treatment."

The surgery will take place Monday in Arlington Tex., by Dr. Keith Meister. Meister is the team physician for the Texas Rangers.

Webb has missed 99 games after being placed on the disabled list after making one start, receiving a no-decision in the season opener.

The 2006 Cy Young Award winner is 87-62 with a 3.27 ERA over 199 games in seven seasons.
