Buchholz could have rehab start Sunday

SAN FRANCISCO -- Clay Buchholz threw three innings in a simulated game on Tuesday. He used all of his pitches and said his recovering shoulder felt very good.

Buchholz is set to throw off the mound again on Friday, and Farrell said Buchholz could pitch in a minor league rehab game Sunday if he continues to feel good.

Right now, Farrell figures Buchholz will need three rehab starts before returning to the major league rotation.

Buchholz has not pitched since June 8 because of shoulder soreness.

* First baseman Mike Napoli’s injured left foot is doing better. Farrell considered him available for defensive or pinch-hitting purposes Tuesday night.

Napoli hasn’t played since Friday.

* Reliever Matt Thornton (oblique) will throw a simulated game Friday, and Farrell said it’s possible he gets activated from the disabled list without going on a rehab assignment.
