"Everyone knows what he's doing and what he can do," said Roberts. "To his credit he continues to excel and dominate at Triple-A. Our guys, in terms of the farm system, it's kind of belaboring for me to ask for it. They know what he brings and what kind of an asset he is."
Roberts, however, said Hyun-Jin Ryu came out of a Friday night rehab start in good shape and will make his next one Wednesday at Triple-A. He is on a pace to return from last year's shoulder surgery in June.
Also, Brandon McCarthy has been slowed in his rehab from last year's Tommy John surgery.
