Brad Miller homered twice and drove in a career-high seven runs, and the St. Louis Cardinals pounded Sonny Gray and the Cincinnati Reds 16-2 on Tuesday night.

Miller sparked St. Louis' six-run first inning against Gray with a two-run double that glanced off the glove of diving first baseman Joey Votto and bounced down the line. He hit a two-run shot in the second, an RBI single in the fifth and another two-run homer in the eighth, clanging a drive off the foul pole in right.

Kolten Wong went 4 for 4 and scored four times as the Cardinals set season highs for runs and hits with 23. St. Louis has won three straight games after a four-game losing streak.

It was the worst loss of the season for the free-falling Reds, who have dropped three straight and four of five. They have been outscored 33-8 during the losing streak.

St. Louis left-hander Kwang Hyun Kim (2-0) pitched five innings of three-hit ball, extending his scoreless streak against the Reds to 11 innings over two starts. No Reds baserunner got past second base against him.

Votto greeted Ryan Helsley with a leadoff home run in the sixth. Curt Casali added an RBI double in the ninth.

Archie Bradley and Brian Goodwin each made their debut for Cincinnati after they were acquired in a pair of trades on Monday. Bradley pitched 1 2/3 scoreless innings, and Goodwin went 1 for 3.

Gray (5-2) had been one of baseball's best pitchers so far this season, but he recorded just two outs in his worst start of the year. He permitted six runs and five hits, struck out one, and walked three.

Eleven Cardinals batted in the 27-minute first inning.

Johan Oviedo (0-1) makes his first career appearance against the Reds on Wednesday night.

Tyler Mahle (1-1) is 1-3 with a 5.40 ERA in six career starts against the Cardinals. He is 0-3 over his last five starts against St. Louis.
