Giants observe moment of silence for Robin Williams

SAN FRANCISCO -- The Giants honored the late actor Robin Williams with a moment of silence before Tuesday night's game against the White Sox.

A brief video tribute accompanied the observance.

Williams committed suicide Monday at his home in Tiburon, about 20 miles north of AT&T Park, where the famed funnyman occasionally appeared to root for the Giants.

Manager Bruce Bochy had keen memories of Williams' appearance in the Giants dugout before a 2007 Interleague game against the New York Yankees. Actor Billy Crystal, a lifelong Yankees fan, accompanied Williams.

"He was his usual self -- full of energy, bouncing around, pulling for his Giants," Bochy said. "He said, 'Hey, we have to take care of these Yankees. I've got a lot on this game.' "

Williams, 63, was very much a northern Californian, with a home in San Francisco's Sea Cliff district and a reported estate in Napa besides his Tiburon residence. This prompted Bochy to say, "It's a sad day for everybody, not just the entertainment business but (also) the Bay Area. ... This guy entertained us for years with his amazing talent. I was shocked. I was stunned. He's as good as there ever was, I think, in the entertainment business. We're going to miss him."

Cain starts rehab process after elbow surgery

SAN FRANCISCO -- Giants right-hander Matt Cain will require three months of rehabilitation following surgery on his throwing elbow, manager Bruce Bochy said Tuesday.

Cain had bone chips and bone spurs removed from his elbow on Monday by Dr. Ken Akizuki, the Giants' team orthopedist. A three-time All-Star, Cain is expected to be fully recovered by the start of Spring Training next February.

"I think he's excited for the fact that he got his elbow cleaned out," Bochy said of Cain, 29.

Bochy related that Cain saved some of the bone fragments in a jar, as players often do. Cain pitched successfully with the chips in his elbow for years.

"It's amazing this guy was pitching, when you look at the jar," Bochy said.

In other injury-related news, Bochy said that catcher Hector Sanchez, whose recovery from post-concussion syndrome was slowed recently when he was struck by another dangerous foul tip, was expected to serve as Triple-A Fresno's designated hitter Tuesday night and go back behind the plate Wednesday. Both games are against Oklahoma City.

Giants fans support Pence with own signs

SAN FRANCISCO -- The Hunter Pence sign craze continued Tuesday, with fans toting humorous, ironic or enigmatic declarations scrawled on cardboard about their beloved Giants right fielder.

Because the fad started in New York during the team's recent three-city trip, this marked the home fans' first chance to join the Pence phenomenon.

Pence himself perpetuated the trend by posing with right-hander Tim Hudson in the Giants clubhouse before the game against the White Sox. The sign they clutched read, "Hunter Pence plays fantasy football with Tim Hudson!!!" The photo received plenty of exposure on Twitter.

Signs brought by fans included, "Hunter Pence knows Victoria's Secret" and "Hunter Pence gives king size bars for Halloween." Away from AT&T Park, SB Nation tweeted a photo of former Major League slugger Jose Canseco holding a piece of paper reading, "Hunter Pence loves Jose Canseco."
