San Francisco Giants: Santiago Casilla to Undergo Knee Surgery

Bad news for the San Francisco Giants bullpen.

Right-haned relief pitcher Santiago Casilla will undergo surgery later in the week to repair his injured right knee. He has a cyst growing in his right tibia, according to Alex Pavlovic of the Bay Area News Group, and trainer Dave Groeschner says he will be “immobilized at least a few weeks.”

Casilla was placed on the 15-day disabled list last week week. He was having a strong season for the Giants, going 3-2 with a 1.89 ERA and one save in 19 innings.

Casilla has been an absolute rock in the back end of the bullpen for the Giants since being called up from the minors in 2010. He played a key role in their first run to the World Series, recording seven wins and a 1.95 ERA in 52 games down the stretch.

Casilla was the team’s closer for much of the 2012 campaign after Brian Wilson went down early in the season (by the way, the “bearded one” is still a free agent), and converted 25 saves before being replaced by Sergio Romo.

He signed a three-year deal worth $15 million, with a club/vesting option for 2016 last offseason. The righty is in his final year of arbitration, meaning that this contract will buy out two of his free agent years.
