CLEVELAND -- Left-handed reliever Aroldis Chapman is slated to begin a Minor League rehabilitation assignment with Triple-A Louisville on Monday.
Chapman, on the 15-day disabled list with left shoulder inflammation since May 16, threw on flat ground in the outfield on Sunday morning with pitching coach Bryan Price.
"If everything goes OK today through the course of the day, as we anticipate, he's scheduled to pitch an inning [Monday] in Norfolk," Price said.
Chapman threw a bullpen session and long tossed on Friday without issue. Price has worked with the 23-year-old on his mechanics after a stretch of wildness following the arm discomfort.
The plan is to give Chapman a couple of days off after his Monday appearance and then possibly have him throw two innings and about 40 pitches. One more outing might come after that.
"If he's throwing the ball well and pain free, we'll be able to activate him towards the end of the month or first of June," Price said.
The club determined that Chapman should have the rehab assignment as opposed to having him throw in simulated games vs. Reds hitters.
"We're not going to wait until the end of the month to have him face hitters for the first time," Price said. "We're pretty confident the delivery is where it needs to be right now. Now we just have to see if No. 1, the arm feels good and No. 2, that the pitch consistency is there. We're better suited to do that in a regular game setting as opposed to a simulated game."
