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."

Phillips still holding down Reds' cleanup spot

CLEVELAND -- Second baseman Brandon Phillips' tenure in the cleanup spot of the Reds' lineup once seemed close to winding down when Scott Rolen came off the disabled list.

That was May 13. Reds manager Dusty Baker, who originally wanted to give Rolen some time to get re-acclimated upon his return by batting him sixth, hasn't yet made the switch to return him to fourth. Phillips, who batted second before Rolen was injured, isn't complaining.

"It doesn't matter what I want. It matters what the skip wants," Phillips said. "I'm going to try and do my job wherever I'm at. If we're winning, I understand that I will stay in the four-hole.

"I always love hitting in the two-spot. I felt comfortable there. I feel like it's more suitable to me and the type of player I am. I can use all my tools. I'm just happy driving in runners right now and doing my job. Even though [Saturday] I didn't get a hit, I did score a run. As long as I do something positive every day, that's my goal."

Phillips entered Sunday batting .323 with five home runs and 26 RBIs and he batted .395 during an 11-game hitting streak that ended on Saturday vs. the Indians.

"You always feel good when you're producing the way that you're supposed to," Phillips said. "I'm having a good time and I'm trying to have some hard AB's and do what's best for the team. As long as I'm doing my job driving in runners, I think I'm OK."

Struggling Gomes sits in Sunday's finale

CLEVELAND -- Batting only .171 and mired in a 0-for-13 stretch, Jonny Gomes did not start as the designated hitter on Sunday for the Reds vs. the Indians. Gomes was 0-for-4 with three strikeouts during Saturday's 2-1 loss to Cleveland.

Fred Lewis, who played left field on Saturday, was the DH for the Reds on Sunday. Lewis came in with limited DH experience and batted .211 (8-for-38) in nine games.

"I try to stay loose as much as possible and try not to let one at-bat linger into the next. It's basically a mind game you play with yourself," Lewis said. "It's different when you haven't done it a lot."

Worth noting

The Reds' series winning streak vs. the Indians ended at seven. Cleveland hadn't won a series over Cincinnati since May 2007.
