Shakeup: Cubs planning to demote Kyle Schwarber to Triple-A Iowa and put Jason Heyward on DL

MIAMI - The Cubs are preparing for a major shakeup that would send struggling World Series hero Kyle Schwarber to Triple-A Iowa and put Gold Glove outfielder Jason Heyward on the disabled list.

Stuck in a 36-35 pattern but still only 1.5 games out of first place, the Cubs are expected to add outfielder Mark Zagunis and reliever Dylan Floro from Iowa before Thursday night's game at Marlins Park.

Schwarber will try to regain his confidence on a Triple-A level he almost skipped while skyrocketing through the farm system as the No. 4 overall pick in the 2014 draft. While still showing flashes of the power (12 homers) that made him a Wrigleyville favorite, his .171 batting average ranked last among qualified big-league hitters this season.

Unable to grip a bat, Heyward has been waiting for a nasty cut on his left hand to heal after trying to make a diving catch on Sunday in PNC Park's foul territory.

For a banged-up Cubs team, Heyward would join a World Series MVP (Ben Zobrist) and a Cy Young Award finalist (Kyle Hendricks) on the disabled list.
