Matt Wallner Injury: Set to start rehab assignment

Wallner (hamstring) will begin a rehab assignment with Triple-A St. Paul on Wednesday, Aaron Gleeman of The Athletic reports.

Wallner landed on the 10-day injured list April 17 due to a Grade 3 left hamstring strain. He progressed enough in his recovery to resume running in early May, and he's ready to take the next step in his rehab program by playing in games at Triple-A. Given how long he's been out, Wallner will likely need multiple games in the minors to get his timing back at the plate before the Twins activate him. Before he was shut down with the injury, Wallner slashed .263/.373/3474 with one home run and three RBI over 67 plate appearances.
