Romero (5-2) allowed one run on one hit over 1.1 innings Thursday to take the loss versus the Rays.
Romero also allowed an inherited runner to score on a two-run home run by Brandon Lowe, which put the Rays ahead for good. Since the start of July, Romero has allowed just two runs over 11 innings, but he's been charged with three blown saves in that span while adding three holds. He remains the Cardinals' top lefty setup man, posting a 2.44 ERA, 0.98 WHIP and 39:9 K:BB with 28 holds and six blown saves over 48 innings this season.
