Gregerson struggled Sunday, allowing three runs on four hits while blowing the save and taking the loss against the Blue Jays. After enduring a rough May (5.91 ERA in 11 appearances), the 31-year-old looked strong in recent outings prior to Sunday's hiccup. With Pat Neshek (2.08 ERA), Josh Fields (2.40 ERA) and Will Harris (0.65 ERA) pitching well for the Astros, and Chad Qualls (4.43 ERA) lurking with prior closing experience, Gregerson's role likely isn't as secure as it was in April. However, manager A.J. Hinch has not given any indication that he's prepared to make a switch in the ninth inning. Consider Gregerson's role safe for now.
