Perez underwent season-ending surgery Wednesday to repair his right rotator cuff, Danny Emerman of KNBR 680 San Francisco reports.
Perez suffered a severe strain of his right rotator cuff in just his second week with the Giants after starting behind the plate in five of their first seven games. He'll be a free agent this winter. Joey Bart now has another opportunity to establish himself as the immediate and long-term answer at catcher in San Francisco, though Rule 5 pick Blake Sabol has also been a factor in the early going. Gary Sanchez is currently getting built up at Triple-A Sacramento after recently joining the organization on a minor-league deal.
