Former D-backs catcher Miguel Montero, who was dealt to the Cubs in December, pinch-hit in the fifth and received a nice ovation from the crowd.
Trumbo went 2-for-3 with a pair of RBIs for the D-backs.
Up next: The D-backs are taking their final roster decisions down to the wire as they wrap up the exhibition season Saturday with a 1:10 p.m. MST contest against the Cubs (watch free on MLB.TV). Trevor Cahill had been scheduled to start, but the right-hander was dealt Thursday to the Braves. Left-hander Vidal Nuno, who will open the season in the bullpen, gets the starting nod Saturday.
