Abel (elbow/triceps) is expected to throw live batting practice Thursday and could soon start up a rehab assignment, MLB.com reports.
Abel landed on the injured list in mid-April due to elbow inflammation and then received a cortisone injection for soreness in his triceps in early May. The 24-year-old is likely to require a handful of rehab starts in the minors to build his arm back up, so he should not be expected to be back with the Twins until late June at the earliest.
