Simulated game may be next step for Ryu

LOS ANGELES -- Hyun-Jin Ryu's return to the Dodgers' starting rotation likely will be sooner than later after his 45-pitch bullpen session on Tuesday.

Ryu threw all the pitches in his repertoire, and showed no signs of the left shoulder blade soreness that put him on the disabled list after an April 27 start.

Manager Don Mattingly, who watched the session, was evasive about the next step for Ryu, assuming he comes out of this workout without a setback.

"There's talk of having him do something to pitch here," said Mattingly. "Exactly what that will be, we have a good idea, but we'd rather wait till tomorrow."

Translated, that seems to mean a simulated game is most likely the next step, perhaps as soon as Friday in Arizona. At the soonest, Ryu could slide back into Paul Maholm's spot in the rotation next Wednesday in New York, unless the decision is made to send him out for a Minor League rehab start.

Prior to Ryu's bullpen session, Chad Billingsley threw 20 pitches off the mound as he rebounds after a setback during his rehab from Tommy John surgery.

Uribe cleared, but still may sit until Friday

LOS ANGELES -- Juan Uribe wasn't starting Tuesday night, and A.J. Ellis wasn't activated, but the Dodgers' lineup could be at full strength in a matter of days.

Manager Don Mattingly said Uribe was cleared for all activities after suffering a mild hamstring strain last week. But Mattingly said he'd prefer to hold Uribe out of the lineup until Friday in Arizona just to be sure.

"He thinks he can play today," Mattingly said. "[Trainer] Stan [Conte] thinks he can play today. But hamstring injuries are dangerous. I'd like to buy him through the off-day [Thursday]. I explained to him. We're in a tough spot when he's not in there."

Justin Turner has filled most of the playing time at third base since Uribe has been out.

Meanwhile, Ellis returned from his two-game Minor League rehab assignment on Tuesday, but was not activated.

"He feels good after catching the last two games," Mattingly said, without indicating when Ellis would be activated.

It will probably be Wednesday. Whenever it is, Miguel Olivo is expected to be optioned back to Triple-A Albuquerque after signing a 45-day advance-consent assignment. Drew Butera has filled most of the playing time behind the plate in Ellis' absence since Tim Federowicz was optioned to Albuquerque.
