Cubs' Duane Underwood: Returns to action Friday

Underwood (elbow) returned to the hill Friday for Double-A Tennessee, allowing one run on four hits and one walk while striking out two over four innings.

The Cubs' top pitching prospect appears to be past the elbow stiffness that kept him back at extended spring training for the first month of the season. This is excellent news, as dynasty-league owners no longer have to worry about the injury turning into something more serious. Underwood should stay with Tennessee for most of the season, but could be heard from in single-season leagues in 2017.
