OAKLAND -- Infielder Adam Rosales, on the disabled list with a strained rib cage, began a Minor League rehab assignment with Class A Stockton on Wednesday night at San Jose.
Rosales had been doing full activity in recent days, and throwing without pain was the final hurdle for him to overcome.
"We'll get him out on a rehab assignment and see how many games that will take," A's manager Bob Melvin said before Wednesday's game. "You like to bring a guy up when he's playing well. When we get back from the road trip we'll see how he's doing."
The A's begin a six-game road trip on Friday and return for their next homestand on April 25. Injured outfielder Yoenis Cespedes has been running and throwing, but he's still not swinging a bat until his left hand feels better.
