The Chicago Cubs have placed closer Brandon Morrow on the 10-day disabled list with right biceps inflammation.
Morrow has 22 saves and a 1.47 ERA in 35 games in his first season with the Cubs. The DL stint is retroactive to Monday.
Morrow, who turns 34 on July 26, also spent time on the DL earlier this season with lower back tightness.
The Cubs also activated outfielder Albert Almora Jr. and relievers Carl Edwards Jr. and Anthony Bass before Thursday night's game against St. Louis. Almora was placed on the family medical emergency list on Sunday. Edwards was on the paternity list, and Bass was sidelined by an illness.
Infielder David Bote and reliever Rob Zastryzny were sent down to Triple-A Iowa.
