Lilly, who is coming off shoulder surgery, rejoined the club on Tuesday but was told by pitching coach Rick Honeycutt to play catch as he regains his strength. Lilly is tentatively scheduled to pitch on Friday, Honeycutt said. Lilly is one of eight established starting pitchers on the roster, with five spots available. Four of the slots are expected to go to Kershaw, Greinke, Chad Billingsley and Josh Beckett. That leaves Lilly, Ryu, Chris Capuano and Aaron Harang battling for the final spot.
Greinke has had minor forearm tightness and skipped a bullpen session Sunday. Ryu, demonstrating the independence of a six-time All-Star in Korea, has rejected staff suggestions to even throw bullpen sessions between appearances.
Greinke told Honeycutt he's had similar discomfort in the spring and merely needed a day of rest. He starts against Team Mexico at Camelback Ranch.
Ryu has told the staff that he never threw bullpen sessions in Korea and he didn't plan to in the Major Leagues. He starts at Goodyear, Ariz., against Cleveland.
Mattingly said he would attend Ryu's game because five days earlier, with squads also split, he watched Greinke and missed Ryu.
But there seems to be some general concern within the organization about Ryu's willingness to accept advice as he makes the transition from Korea to the Major Leagues, where the competition is tougher, starters pitch with one fewer day of rest and the season lasts one month longer than in Korea.
"I want to see Ryu this time," said Mattingly. "I didn't see him last time and I'd like to see if it's getting better."
The Dodgers, with an excess of starting pitchers, have stated that Ryu does not have a rotation spot locked up, despite the club's $62 million commitment to him. His contract prevents a Minor League demotion without his consent, but he could wind up in the bullpen if Mattingly and Honeycutt believe they have five better starters.
Harang was scouted by the Brewers and Orioles when he pitched three innings in a Minor League game on Monday.
Beckett's next start has been moved up a day and switched to a Minor League game so he can work on mechanics without impacting the big league club.
And Scott Elbert, coming off a pair of elbow operations, has been cleared to resume playing catch, starting on Wednesday. Elbert will open the season on the disabled list.
