SCOTTSDALE, Ariz. — Giants infielder Freddy Sanchez took ground balls at second base and threw to first Wednesday for the first time since he dislocated his right shoulder on June 10, a significant moment in his rehab.

Sanchez returned to the field two days after feeling some soreness in his back. He’s not too worried about his short-term prognosis though. He’s looking forward to being ready by opening day.

“That’s the main goal,” Sanchez said. “I’m just anxious to get out there. Anxious is an understatement.”

San Francisco manager Bruce Bochy said he hopes to have Sanchez ready to play in a game by the second week of March.

Sanchez and catcher Buster Posey, also coming off surgery, figure to improve both the Giants’ anemic offense and shoddy defense.
