Giants pitcher Tristan Beck to have surgery on throwing arm

SCOTTSDALE, Ariz. --San Francisco Giants right-hander Tristan Beck is scheduled to have surgery Monday to remove an aneurysm in the upper part of his pitching arm.

He will have the procedure at Stanford, where he was examined by a vascular specialist this week, and the timetable for his return to the mound is unclear until after the surgery -- but his availability for opening day is in doubt.

Beck was competing for a spot in the back end of the rotation for San Francisco, which has been out of the playoffs the past two seasons and hired new manager Bob Melvin to replace Gabe Kapler.

"Disappointment is definitely the operative word," Beck said. "Devastation. All that. But it's interesting. This feels different. I've had injuries in the past, and there's definitely two sides to this. Obviously, I came in with an opportunity to go out there and compete for a really meaningful role on this team. That meant a lot to me. ... It's disappointing to not be able to follow through on that, at least early.

"Then there's kind of the flip side," he continued. "This is something that could have been a little more serious. Something that kind of feels like it has more off-the-field implications. I'm just really thankful for the great people we have around. The fact that this was just absolutely textbook by the Giants' medical [staff] and all parties."

He was placed on the 60-day injured list on Sunday.

Beck, 27, went 3-3 with a 3.92 ERA over 33 appearances with three starts as a rookie last season.
