Austin Riley brought his home-run swing with him to Atlanta.
Riley, who hit 13 home runs in his past 18 games for Triple-A Gwinnett before being promoted to the big leagues, homered on his second at-bat Wednesday night at SunTrust Park.
His solo home run in the fourth inning of the Braves’ game against St. Louis was estimated to travel 438 feet into the left-center field stands at a 109.1-mph exit velocity. It came against Cardinals starting pitcher Michael Wacha.
Riley, making his MLB debut, struck out in his first at-bat in the second inning.
