"He did OK," said Mattingly. "The key will be tomorrow. We'll see if it gets sore when he gets on the field. Stan [Conte, trainer] is a little more confident. We feel it's minor; we don't want to turn it into major."
Hyun-Jin Ryu (left shoulder blade inflammation), meanwhile, was able to play catch with more velocity, and Mattingly said his stint on the disabled list should not be long-lasting. But Ryu will not be able to return on Tuesday, when he's eligible.
Catcher A.J. Ellis (left knee surgery) will begin a Minor League rehab assignment for Triple-A Albuquerque on Sunday, and he could be activated next week. Ellis took an additional 15 at-bats in an extended spring game on Saturday.
