Manny Ramirez might not be ready to play for the Athletics by May 30 when his suspension ends. Bob Melvin says Oakland wants to make sure Ramirez is fully prepared and comfortable with his swing before he plays in Major League games following his stint with Triple-A Sacramento. Ramirez was held out of Sunday's game with the River Cats because of a wrist injury that Melvin called "a little setback." "We want to get him close to 40 at-bats and, whether or not we get there in 10 days, I don't know," Melvin said. "We're not locked into the 30th. We want to make sure he's productive, he's feeling good about his swing, he's getting his hits - all of those things you want to see when, potentially, he gets here. I'm not sure on the 30th, and it's going to be a progression each and every day. We certainly hope that's the case."
