CHICAGO — The first test of the Chicago Cubs starting pitching depth has arrived.
Jameson Taillon, who was scheduled to start Thursday at Wrigley Field, was placed on the 15-day injured list with a left groin strain.
The move was retroactive to Monday, and the Cubs believe the right-hander will be ready to return soon after he is eligible. The Cubs called up Javier Assad from Triple-A Iowa to take Taillon’s place in the rotation, and Assad started Thursday against the Los Angeles Dodgers.
