Lowry slated for elbow surgery

Giants expect left-hander to be ready for Spring Training

SAN FRANCISCO -- Giants left-hander Noah Lowry will undergo arthroscopic surgery Tuesday to remove a bone spur from his throwing elbow, although he's expected to be ready for Spring Training.

The surgery will prevent Lowry from throwing for at least six weeks and likely will knock him out of participating in winter ball. Lowry, who has been sidelined all season while trying to rebound from forearm surgery in March, had hoped to pitch for Mazatlan in the Mexican Pacific League.

The procedure, to be performed by Dr. Lewis Yocum in Los Angeles, was described as "diagnostic arthroscopy," indicating that Yocum will search for other possible maladies within Lowry's elbow. Lowry underwent an MRI and was examined earlier this week by Yocum, who discussed the issue with Giants team orthopedist Ken Akizuki.

It remains to be seen whether the Giants will try to add depth to their starting rotation in the offseason or assume that Lowry, their leading winner in two of the previous three seasons, will return physically whole. On Friday, manager Bruce Bochy took the upbeat view.

"We're being optimistic that we can count on him and this surgery will clean up everything and give him peace of mind," Bochy said. "Hopefully this is the last step to his being recovered."

Lowry, 27, was 40-31 with a 4.03 ERA in 106 appearances (100 starts) from 2003-07 with the Giants.
