ATLANTA >> Dodgers manager Don Mattingly was hoping to use an off-day in the schedule on Monday to give his starters an extra day of rest.

Now, the possibility exists that Roberto Hernandez, Zack Greinke and Clayton Kershaw will all pitch on regular rest in the three-game series against the San Diego Padres beginning Tuesday at Dodger Stadium.

That’s because Hyun-Jin Ryu left last night’s game with a strained right gluteal muscle, putting his next start in jeopardy.

“I don’t feel like his chances are very good of pitching on his turn,” Mattingly said of Ryu. “Let’s say he can’t pitch on his turn, if we’re going to go hypothetically. He may be ready to go next time.”

That would be either Saturday, August 23, or Sunday, August 24, at home against the New York Mets. In either case, placing Ryu on the 15-day disabled list would prevent Ryu from making the start. The Dodgers aren’t ready to make a DL decision on Ryu because he hasn’t had an MRI or an examination with team physician Dr. Neal ElAttrache.

It’s also possible that Kevin Correia will start Tuesday’s game against the Padres. In that case, Hernandez and Greinke would then start Wednesday and Thursday, respectively. Kershaw would start Friday, August 22, against the Mets.

On Monday, Mattingly left open the possibility that Correia would get another turn if another starting pitcher was injured. Correia was the winning pitcher in his Dodgers debut against the Braves, pitching six innings and allowing two runs.

However, the manager also said Thursday that Correia could pitch today in case of an emergency.

Stay tuned. It’s doubtful we’ll know more today unless Ryu gets his MRI and the Dodgers learn the results during the game.
