Pirates placed RHP Kirby Yates on the 15-day injured list with a right shoulder impingement.

Yates, who had a 2.19 ERA in 13 games since being acquired by the Pirates on August 3, will miss at least a few weeks. Shoulder injuries for a pitcher aren’t good. The 39-year-old has been a stabilizing force in the pen and will now yield his spot to Khristian Curtis.
