SAN FRANCISCO -- Giants manager Bruce Bochy maintains there is a "50-50" chance Freddy Sanchez could return to the lineup sometime in May.
"He's doing his throwing and trying to get back to his rehab," Bochy said. "He's doing better."
Sanchez has had a few setbacks in his attempt to return from right shoulder surgery last August. He was originally on track to be in the Opening Day lineup but was shut down after appearing in five Spring Training games.
Sanchez said he felt something in his arm during a recent rehab stint with the San Jose Giants and was again shut down.
After spending several days with the big club, Sanchez was sent to Arizona for additional treatment and workouts before resuming his rehab assignment.
"In his time here, he made some progress," Bochy said. "We're still hopeful we will get him back in May."
Meanwhile, the Giants have used Emmanuel Burriss, Ryan Theriot and Joaquin Arias at second base. The trio has combined to hit .256 with no home runs and nine RBIs.
