Lilly, on the 15-day disabled list with recurring neck pain, threw 83 pitches vs. Angels affiliate Inland Empire and was charged with seven runs (six earned) on eight hits, two of them home runs, one a grand slam by C.J. Cron.
Before hearing Lilly's line, manager Don Mattingly said the main goal of the rehab start was to build up Lilly's pitch count.
"Obviously, if he comes in and his neck is killing him, but more than anything it's just to build him up," he said. "We look at it that he's past the injury thing and has got to build up his arm."
Lilly is scheduled to return to the rotation for a Saturday start against San Diego.
