The D-backs were able to break through against Royals starter Chris Young in the third inning as they sent 10 men to the plate, collecting five hits and scoring five runs.
Pollock, David Peralta, Jake Lamb, Yasmany Tomas and Rickie Weeks Jr. each collected RBIs in the frame.
Pollock was on third when Peralta hit a grounder to second base. Omar Infante threw home to try and get Pollock, who slid headfirst, touched home plate with his left hand and then grabbed his right elbow area in pain.
