Peralta (4-4) blew the save and took the loss in Thursday's 4-2 loss against Miami. He allowed four runs on three hits and one walk while striking out three over 1.2 innings.
Peralta entered Thursday's game up 2-0 in the seventh inning as a reliever and set down the side in order, but he cost the Brewers the game with a mistake to Avisail Garcia in the eighth. The 26-year-old loaded the bases on a couple of hits and a walk, and Garcia then tagged him for a grand slam to put the Marlins up 4-2 and saddle Peralta with his fourth loss of the season. Peralta has a 3.77 ERA, 1.07 WHIP and 82:27 K:BB over 74 innings and is closing the campaign in a relief role.
