The Pittsburgh Pirates have an important piece of their bullpen working his way back from a recent injury. Pirates left-handed pitcher Ryan Borucki struggled in his most recent appearance out of the bullpen in the series opener vs. the Texas Rangers at PNC Park on June 20. Borucki left with Pirates assistant athletic trainer Tony Leo in the middle of the inning, with fellow left-handed pitcher Caleb Ferguson coming in for him. The Pirates placed Borucki on the 15-day injured list on June 21 with low back inflammation and brought up right-handed pitcher Hunter Stratton in replacement.
