Brewers activated LHP Jared Koenig from the 15-day injured list.
He takes the spot of Craig Yoho, who was sent down Thursday. Koenig had been out since early April with an elbow sprain. The Brewers had him spend nearly a full month on a rehab assignment in Triple-A, during which time he had a 3.72 ERA in 11 appearances. Koenig had a 2.87 ERA, two saves and 27 holds as one of the Brewers’ key relievers last year.
