Cubs Demote Clemson's Colvin
The Cubs are giving outfielder Tyler Colvin a chance to try to work out of his hitting funk in the minor leagues. Chicago optioned the struggling outfielder to triple-A Iowa on Tuesday before the second game of a series against the Cincinnati Reds. The Cubs called up outfielder Tony Campana to take his spot. They also swapped relievers, replacing Marcos Mateo with Scott Maine.
