Cueto takes a 3-0 record into Sunday's start against Milwaukee, his first since a 6-0 win at Pittsburgh on May 31. He was placed on the DL on June 5 for the second time this season, on both occasions with a strained muscle in his right shoulder.
Villareal's second stint with the Reds this season lasted one day. He was recalled Saturday when right-hander Jonathan Broxton was placed on the 15-day DL. Villareal did not pitch in Saturday's 7-0 loss to the Brewers.
