Helsley (elbow) threw batting practice against live hitters Monday, Matt Weyrich of The Baltimore Sun reports.
Helsley had already completed multiple bullpen sessions over the last two weeks, but his ability to face hitters Monday means that he's checked off another box in the recovery process for his inflamed right elbow, which sent him to the injured list May 1. If Helsley checks out fine following the workout, the Orioles could clear him to head out on a rehab assignment later this week.
