SF@COL: Casilla injures leg on groundout to short

CINCINNATI -- Giants right-hander Santiago Casilla threw a 25-pitch bullpen session Thursday in Cincinnati and is scheduled to throw another Saturday.

San Francisco manager Bruce Bochy said Casilla could begin a Minor League rehabilitation assignment in 10 days to two weeks "if all goes well."

The Giants' top setup man injured his right hamstring while running to first base after batting during the ninth inning of a 5-1 loss May 21 at Colorado. An MRI revealed a Grade 2 (medium) strain.

Belt slated to get pins out of broken thumb

SF@LAD: Belt takes pitch to hand, leaves game

CINCINNATI -- San Francisco first baseman Brandon Belt is scheduled to visit a doctor Friday and have two pins removed from his fractured left thumb, Giants manager Bruce Bochy said Thursday.

"It will depend on how the next 10 days to two weeks go as far as when he can start rehab," Bochy said.

Belt, 26, had the pins inserted May 13. He was hit on the hand by an 87 mph fastball from Dodgers starter Paul Maholm during a May 9 game at Los Angeles.

Worth noting

• Giants bench coach Ron Wotus had to leave the club Thursday to attend to a family matter. Bochy said Wotus would rejoin the club Friday in San Francisco.

• Injured second baseman Marco Scutaro is performing light conditioning activities in Arizona. Scutaro is on the 60-day disabled list with a nagging back injury.
