Diaz, who went 0-for-4 with an RBI ground out in his major league debut behind the plate Sunday, impressed manager Clint Hurdle with his defense. "I thought Diaz caught a fantastic game," Hurdle told the Pittsburgh Tribune-Review.
A game after Philadelphia stole five bases with Francisco Cervelli catching, Diaz picked off a runner at second base and nailed the only would-be base stealer. It remains to be seen whether Pittsburgh will keep Diaz after backup Eric Fryer returns from paternity leave, but he's already left a positive impression with his manager.
