Luke Gregerson recently spent close to a week away from his teammates in order to deal with a personal matter, but returned to the hill yesterday in a scoreless inning of work. However, the 31-year-old right-hander once again left the team tonight to deal with an undisclosed personal matter, leaving Chad Qualls to fend off the Blue Jays in the ninth-inning in a save situation. And that he did, on just 12 pitches. Qualls retired Toronto’s 5-6-7 hitters consecutively — two by ground out, one via strikeout — to notch his fourth save in five opportunities this season. Gregerson is expected back with the team tomorrow (Friday, 5/15) and should assume the closer’s role, unless the Astros’ brass decides to provide the righty with an opportunity to get some work in during a lower leverage situation.
