A Chicago Cubs trade idea sends two top-ten prospects to the Arizona Diamondbacks for starting pitcher Zac Gallen, following the season-ending injury to Corbin Burnes.

Arizona Diamondbacks right-hander Corbin Burnes will have Tommy John surgery next week, manager Torey Lovullo announced prior to Friday's series opener with the Cincinnati Reds at Great American Ball Park. Burnes exited his start this past weekend with an elbow injury and tests this week revealed a UCL tear significant enough to require surgery.

Diamondbacks starter Ryne Nelson is back in the rotation with Corbin Burnes' season-ending elbow injury. But first, Friday's suspended game resumes.
