UPDATE: Jonathan Sanchez placed on disabled list with biceps tendinitis

UPDATE: Well, Jonathan Sanchez was pulled from the Giants’ rotation. Just not for the reason we thought.

According to Andrew Baggarly of the San Jose Mercury News, Sanchez has been placed on the disabled list with left biceps tendinitis. Zito will be activated from the disabled list to start the second game of a doubleheader Tuesday and figures to remain in the starting rotation until Sanchez is healthy and (more likely) effective.

9:32 AM: Remember what I wrote last night about Barry Zito going to the bullpen following Tuesday’s spot start?

Perhaps that talk was premature.

After Jonathan Sanchez allowed three runs and walked since over just 4 2/3 innings last night against the Indians, Giants manager Bruce Bochy told Andrew Baggarly of the San Jose Mercury News that the struggling southpaw may get a break from the starting rotation.

“Just watching him, I can tell he’s lost some confidence,” Bochy said. “It’s just not happening. He’s all over the board, and that’s not him. We may keep throwing him out there. We may back him off. We’ll see. But getting (Barry) Zito back does give us that option.”

Sanchez has a 3.81 ERA through 16 starts this season, which doesn’t sound too bad on the surface, but he currently leads the majors with 59 walks over 89 2/3 innings. He has walked at least five batters in four out of his last five starts and hasn’t completed seven innings in a start since May 28.
