Lilly came out of Saturday night's start in Colorado with a neck that Mattingly said had more to do with the way he slept on it than an actual injury. Lilly is likely to throw a bullpen session Tuesday.
Casey Blake and Dee Gordon took the next step in their recoveries from neck and shoulder injuries, respectively, by taking live batting practice Monday.
If Blake's neck continues to show improvement, he said he could play as early as Tuesday night.
Gordon appeared tentative taking his swings. He is scheduled to take batting practice with the club Tuesday and Wednesday. If the club feels he's ready, he would go out for at least two games on a Minor League rehab assignment before being activated.
Reliever Kenley Jansen, on the disabled list with an irregular heartbeat, came out of his two-strikeout rehab inning for Class A Rancho Cucamonga on Sunday night with no problems and is scheduled for another outing Tuesday night. He could be activated for Friday night's game.
