Puig went 3-for-5 with a homer and double Tuesday night, but Mattingly was still marveling over the right fielder's full-speed sprinting catch of Nolan Arenado's foul ball on the warning track between the Colorado dugout and the foul pole.
"He made a cut like a running back," said Mattingly. "It was unbelievable. It's gotten to [the point where] you expect him to do something all the time. If he doesn't get a hit or get on base, it's like, 'What's going on?'"
While Puig's debut is being compared to that of Joe DiMaggio, Mattingly was asked if he had seen any comparable player who made an immediate impact and kept it up to be a great player.
"Junior Griffey was like that," he said. "He tore it up and kept tearing it up. You see the highlights, great plays at the wall, throwing guys out, stealing bags. That kind of guy. Yasiel is a guy that does everything."
