"He feels as good about this one as he did about the last one, maybe even better," manager Bob Melvin said. "I wasn't out there for this one, but he came in with a smile on his face and said he was nastier this time than he was last time."
The plan is for Anderson to throw another bullpen session before week's end. Should all go well, it's likely he'll then throw to hitters, possibly in a simulated game or simply live batting practice, before the A's decide if he's ready for a rehab assignment.
"Just depends if everything goes well," Melvin said. "We want to make sure every step that we take with him goes accordingly."
