Jay Bruce homered, doubled and knocked in four runs for the Reds, giving him nine RBIs in four games. Brandon Phillips returned from left thumb surgery wearing a brace and was 0 for 4 with a walk.
Logan Ondrusek (2-3) entered with one out in the 10th and gave up consecutive singles to Matt Holliday, Matt Adams and Peralta. Ondrusek (strained right shoulder) was activated from the disabled list earlier in the day.
Peralta's RBI single in the first was just his second in 32 at-bats against the Reds this season. He also doubled and scored the tying run on A.J. Pierzynski's hit off Jumbo Diaz in the eighth.
