They put relievers Tyson Miller (left hip impingement, retroactive to March 21) and Ryan Brasier (strained left groin, retroactive to March 25) on the 15-day IL, freeing up room on the active roster for Keller and Eli Morgan, who the Cubs recalled from Triple-A Iowa.

From there, the Cubs will be part of the itinerant Athletics’ home opener at a Triple-A ballpark in Sacramento, Calif. Another West Coast trip is scheduled for the middle of April, and by that point the Cubs will have played the San Diego Padres six times.
