McHugh (arm) threw 25-30 pitches off a mound at about 70 percent Monday, Jake Kaplan of the Houston Chronicle reports.
The 29-year-old reportedly felt good after throwing his first bullpen session of spring training, and he's hoping to progress to live batting practice soon in a Grapefruit League game. Despite being delayed considerably due to a dead arm at the beginning of camp, the Astros and McHugh feel optimistic that he'll be in their rotation come Opening Day.
