Stewart (shoulder) has been playing catch from 90 feet and is scheduled to throw from 120 feet Wednesday, Do-Hyoung Park of MLB.com reports.
The right-hander landed on the injured list with shoulder tendinitis in early May and received a PRP injection a couple weeks later, but his recovery progress over the past month has been slow. Stewart will need to resume mound work before a rehab assignment is considered, and he's likely at least a couple weeks away from rejoining the Twins.
