June 7 (UPI) -- Cincinnati Reds left fielder Scooter Gennett hit a historic four home runs Tuesday at Great American Ball Park.
Gennett's achievement was a first for the oldest franchise in Major League Baseball.
The five-year veteran entered the game with just three home runs and 20 RBI. He plated 10 runs Tuesday in the Reds' 13-1 win against the St. Louis Cardinals. The Reds have won the first two games of the four-game series.
Gennett's night began with a blooper RBI single in the first inning.
In the third inning, he smacked a grand slam off of Adam Wainwright. That shot went halfway up the right field bleachers. The hit gave the Reds a 5-0 advantage. The home run traveled 424 feet, according to ESPN's home run tracker.
In the fourth inning, he returned for a two-run blast off of John Grant. That homer went to dead center and gave the Reds a 10-0 lead. His second dinger traveled an identical 424 feet.
Gennett smashed a 375-foot solo shot off of Gant in the sixth. His third home run of the game went to left field and made the score 11-0.
His last home run was a two-run laser off of John Brebbia in the eighth inning. He pulled the 378-foot homer to right field. His final shot also left the stadium the quickest, with a speed of 106.2 mph off of his bat, according to the home run tracker.
"Just the whole game I was trying to relax," Gennett told MLB Network after the game. "You are talking to me after this game but you didn't want to talk to me when I was 0-for-19 a couple of weeks ago. I was just trying to relax and get good pitches to hit."
"It's baseball man. When you don't expect to get something, that's when you get it."
Gennett was the 17th player to hit four home runs in one game. He is the 14th guy to plate 10 runs in a single game.
Gennett is now included on a list of Lou Gehrig, Rocky Colavito, Mike Schmidt, Mike Cameron and Carlos Delgado as the only players in baseball history to hit four home runs in four consecutive plate appearances.
The 27-year-old's third inning homer was his first since April 11. Gennett is now hitting .302 this season. The outfielder played the first four years of his career with the Milwaukee Brewers before joining the Reds in March off of waivers.
A record seven grand slams were hit on Saturday in Major League Baseball, including Albert Pujols' 600th career long ball.
