The Arizona Diamondbacks reinstated RHP Taijuan Walker from the Paternity Leave List. To make room on the 25-man roster, Arizona optioned LHP Anthony Banda following last night's game.
 
Walker, 24, left the team on Thursday to be with his wife, Heather, for the birth of their first child. He has gone 6-4 with a 3.61 ERA (35 ER in 87.1 IP) in 15 starts for the D-backs this season.
