Game Report: Reds 13, Cardinals 1

Scooter Gennett came into Tuesday night’s game against the Cardinals with one hit in his last 20 at-bats and three home runs in 111 at-bats for the Reds this season.

He might have been one of the least likely players to do what he accomplished at the Great American Ballpark, turning in the greatest individual game in history against the Cardinals.

Gennett became the first player to ever hit four home runs or drive in 10 runs in a game against the Cardinals. He hit a grand slam off Adam Wainwright in the third, a two-run homer in the fourth and a solo homer off John Gant in the sixth and capped his night with another two-run homer off John Brebbia in the eighth.

Gennett’s night also included an RBI single in his first at-bat in the first inning.

The grand slam came after the Cardinals challenged a call when they had recorded an out. The umpires ruled that Stephen Piscotty caught a foul ball in the right field corner but a run scored on the play, and the Cardinals challenged the call. The call was overturned, sending the runner back to third. The hitter, Eugenio Suarez, then drew a walk to load the bases and bring Gennett to the plate.

The big night by Gennett sent the Cardinals to their fifth consecutive loss.

Here is how the game broke down:

At the plate: The Cardinals’ only run scored on a homer by Piscotty leading off the seventh, just their third hit of the game … They have scored three runs or less in six of their last seven games … Dexter Fowler was 0-of-2 before coming out of the game and Matt Carpenter was 0-of-4, making the two a combined 6-of-42 in the six games when Carpenter has hit in the second spot in the batting order … Fowler is now hitting .220 for the year while Carpenter’s average has dropped to .209.

On the mound: Wainwright had allowed only one run in his previous 26 innings coming into the game but did not make it through the fourth inning. He was charged with nine runs, the most he has allowed in a game since the Reds also scored nine against him on Aug. 28, 2013 … Suarez knocked Wainwright out of the game with a bases-loaded triple in the fourth … Gennett’s grand slam was the third allowed by Wainwright in his career, the last hit by Bryan LaHair of the Cubs on April 13, 2012 … Gant made his Cardinals debut in relief of Wainwright and was greeted by Gennett’s second homer. He pitched 3 1/3 innings, allowing three hits, two of them Gennett home runs … Brebbia pitched the eighth, and a one-out walk made sure Gennett got his final at-bat of the night.

Key stat: The record for most RBIs in game against the Cardinals had been nine, set by Johnny Rizzo of the Pirates in the second game of a doubleheader on May 30, 1939. The last player to hit three homers in a game against the Cardinals was Casey McGehee of the Brewers on Aug. 3, 2011.

Worth noting: The last Cardinal pitcher to allow a home run to the first batter he faced was Evan MacLane on July 7, 2010 against Colorado, the first of only two games he pitched in his career … Kolten Wong played the complete game at second base for the Peoria Chiefs on Tuesday night and went 0-for-3 with a walk and also was hit by a pitch. He also stole a base … Randal Grichuk’s game at Palm Beach was rained out … Zac Gallen, the Cardinals’ fourth-round pick in last year’s draft, made his Double A debut on Tuesday night and allowed one run in 5 2/3 innings. Magneuris Sierra returned to the Double A club and was 4-of-4 plus a walk.

Looking ahead: Lance Lynn will get the start on Wednesday night in the third game of the series.
