McHugh (elbow) threw a successful session of live batting practice Wednesday, Brian McTaggart of MLB.com reports.

It's a major step in the right direction for McHugh, who has been out since experiencing discomfort in spring training. The next step appears to be a simulated game earlier this week, which should give trainers a better estimate as to when the righty will be able to begin a full rehab assignment. McHugh is looking to improve after posting a somewhat disappointing 4.34 ERA and 1.41 WHIP last season.
