Astros left-hander Erik Bedard said Wednesday he hopes to soon return to the mound but does not have an official timetable for his activation. Bedard pulled a right gluteal muscle during his only spring training start, a Feb. 26 two-inning appearance against Detroit. The 33-year-old felt a tweak during his last couple pitches, then awoke the next day in pain. Bedard wore a wrap around his waist Wednesday morning. He’s making progress during his recovery but is taking a cautious approach, since he wants to be fully healthy for the start of the Astros’ regular season. “Might as well be more careful now,” said Bedard, who’ll throw a bullpen session before returning to the mound. “If you keep trying to aggravate it, it’s not going to be good.”
