Riley went 2-for-5 with a three-run home run in Wednesday's 7-6 extra-innings loss to the Brewers.
The third baseman took Corbin Burnes deep in the third to get Atlanta on the board. The blast snapped a 13-game homer drought for Riley, a stretch during which he hit only .157 (8-for-51) with a single RBI. He carries a .799 OPS with eight home runs and 18 RBI through 37 games.
