Last night's game between the Cubs and Rockies was postponed due to rain and hail at Coors Field. It will be made up as part of a doubleheader today. Chicago's Jake Arrieta will oppose rookie Antonio Senzatela in the opener. John Lackey and Colorado's Kyle Freeland will start on the mound in the nightcap.
The Cubs are placing outfielder Jason Heyward on the 10-day disabled list due to a knuckle injury. The move is retroactive to May 6th. Heyward is hitting .253 with three homers and 17 RBI this season. The Cubs recalled pitcher Dylan Floro from Triple-A Iowa in a corresponding roster move.
The Cubs also traded outfielder Matt Szczur to San Diego for a minor league pitcher.
