Maeda (arm/groin) will begin a rehab assignment with Triple-A St. Paul on Wednesday.
Maeda threw 35 pitches in a bullpen session Sunday, and he'll return to game action during his rehab start Wednesday. The right-hander still doesn't have a clear timetable to return to the major-league rotation, but he could be reinstated from the injured list as early as next week if all goes well.
