Scooter Gennett has tied a major league record by homering four times for the Cincinnati Reds against the St. Louis Cardinals tonight. Gennett, who drove in 10 runs, connected for his second career grand slam off Adam Wainwright, then had a solo homer and two two-run shots as he became the 17th major leaguer with four in a game and the first since Josh Hamilton in 2012. No player has ever hit more than four in a game. Gennett singled his first time up and then homered in four straight at bats as Cincinnati hammered the Cards 13-1. His 10 RBIs matched the club record.
