Robles (4-1) retired just two batters while allowing five runs on four hits and a walk during Monday's loss to Arizona.
Robles has now allowed nine runs over 1.2 innings through his past two appearances. He entered the recent two-game funk with a 1.42 ERA, 1.05 WHIP and 9.5 K/9 over his previous 18 outings (19 innings), though, so there's a good chance he bounces back sooner than later.
