Cubs' Duane Underwood: Struggles continue with Double-A Tennessee

Underwood gave up one run in four innings against Double-A Jackson on Friday, but he also gave up four hits, two walks, and hit a batter.

Underwood got off to a late start this year due to an elbow injury, but he's struggled all season for Tennessee. He's 0-4 with a 5.12 ERA in 10 starts and has walked 24 in 45.2 innings. Though he's still considered one of the best pitching prospects in the Cubs' system, Underwood appears to have a lot of work to do.
