CINCINNATI — Streaking Salvador Pérez had three more hits, including a homer and RBI double, Reds left-hander Wade Miley made another early exit after a misstep, and the Kansas City Royals beat Cincinnati 5-4 on Wednesday for their fifth victory in six games.

The Royals’ offense has led the way during the surge. It scored one run at a time to keep it going, led by Pérez’s homer, double and single.

Brad Keller (2-0) allowed two singles in six shutout innings. He was acquired from Cincinnati in the 2017 Rule 5 Draft.

The bullpen barely held on.

Jesse Winker, Freddy Galvis and Josh VanMeter homered in the seventh, cutting it to 5-4. Josh Staumont escaped a two-on threat in the eighth with a pair of called third strikes.

Trevor Rosenthal walked the bases loaded with one out in the ninth but got Christian Colón to ground into a double play, earning his fourth save in as many chances.

The Reds wasted a chance to get back to .500 and lost their only left-handed starter after less than two innings.

They signed Miley (0-2) to a two-year, $15 million deal in the offseason. He retired only five batters during his Reds debut, giving up six runs in a loss to the Cubs on July 27. He went on the injured list with a sore groin afterward.

Miley returned and appeared to hurt himself when he stepped awkwardly while covering first base in the second inning. After talking to a trainer, Miley stayed in the game, walked the next batter and left after only 1 2/3 innings again. There was no information about his condition.

Pérez connected for his fourth homer off Tyler Mahle, extending his hitting streak to 10 games — his longest since 2017. He’s batting .429 (18 for 42) during the streak.

The Royals are 17-10 all-time vs. the Reds, including 12-4 since the start of 2009. They’re 8-4 at Great American Ball Park, the best mark by a team with at least 10 games.
