Acton (shoulder) was expected to resume facing hitters last week, MLB.com reports.
The Twins haven't confirmed whether Acton has completed a live batting practice, but he was on track to take the next step forward in his rehab process after he tossed four bullpen sessions without issue since landing on the injured list April 28. Given the length of his stint on the shelf due to a right shoulder strain, Acton could need an extended rehab assignment before rejoining the Minnesota bullpen.
