For the first time in his career, Astros reliever Luke Gregerson says he’s making quality pitches and not getting the results he’s had in the past. Gregerson gave up a two-out, game-tying homer to the A’s Jed Lowrie in the ninth inning Saturday for his fifth blown save in his past 11 outings, forcing manager A.J. Hinch to make a switch at the closer role.
