OAKLAND -- Ryan Cook is "pretty close" to being deemed ready for big league action, manager Bob Melvin said Wednesday.
The right-handed reliever, slowed in spring by shoulder inflammation, will make a rehab appearance with Class A Advanced Stockton on Thursday, and that could be Cook's final outing before coming off the disabled list when eligible Saturday.
Outfielder Craig Gentry can be activated on the same day, but it's not yet known if that will happen. Gentry's wife, Jordan, gave birth to a girl on Tuesday night in the Bay Area, and the A's will have to decide whether he needs any more Minor League at-bats following his return.
"I think I'll leave that up to the training staff and whether we feel like this period creates a gap where we feel like he needs another game," said Melvin. "I'm not certain yet."
When Gentry does return, the A's will have to designate Sam Fuld for assignment. Cook's reinstatement will force them to option either Evan Scribner or Drew Pomeranz to Triple-A Sacramento.
