The Twins were intentionally vague about the plan for Nathan to test it this weekend. Manager Ron Gardenhire says he doesn't want it "to become a media circus."
Tests showed a torn ulnar collateral ligament on March 9. The injury could require season-ending Tommy John surgery. But Nathan wants to test it out first to see if he can pitch through the pain and not miss what was shaping up as a promising season for the Twins in their new ballpark.
Gardenhire would not say what day, or where, Nathan will play catch.
