Riley went 1-for-4 with a solo home run in Thursday's win over the Marlins.
The third baseman got Atlanta on the board by taking Max Meyer deep in the first inning. Riley is coming off a strong July that saw him slash .280/.324/.527 with five homers and 14 RBI in 24 games, but with only 15 long balls on the year, he'll need to stay hot down the stretch to reach 30 for a fourth straight season.
