The bad news for the National League Central team is it announced it placed Ian Happ on the 10-day injured list because of a left oblique strain. However, the good news was that it called up highly regarded prospect Moisés Ballesteros in a corresponding move.

The Chicago Cubs have promoted catching prospect Moisés Ballesteros for his MLB debut. Ballesteros is hitting seventh as the DH in Tuesday's game against the Miami Marlins. In a corresponding move, the Cubs have placed outfielder Ian Happ on the injured list on account of an oblique injury that has sidelined him since May 9.

One of the Cubs’ best hitters this season is heading to the injured list. Chicago announced Tuesday that outfielder Ian Happ has been placed on the 10-day IL with a left oblique strain.
