Giants first baseman Brandon Belt will undergo season-ending arthroscopic surgery on his right knee Saturday in San Francisco.

Dr. Ken Akizuki will perform the procedure.

"It's obviously disappointing for Brandon and for all of us," manager Gabe Kapler said Friday. "We've been trending in this direction and Brandon has fought it so hard and wanted to be out there for his teammates and for all of us, and we just weren't able to get over the hump."
