Puig played a central role in the clinching Game 4 victory, too. He doubled leading off the eighth inning and scored on Juan Uribe's go-ahead two-run homer.
But Mattingly was more impressed by Puig's decision-making than his numbers.
"I was really proud of him this last series," Mattingly said Wednesday before the club's Dodger Stadium workout. "A lot of good decisions from Yasiel this last series. He made a couple of hard turns at first where he didn't go and it was the right play. I saw him hit the cutoff man a lot. We saw patience at the plate for the most part through the series. Just really proud of him.
"I think everybody questioned -- was he going to be able to make good decisions? He may still get excited and do something that we don't want. But I felt like he showed a lot of maturity in that series."
That's a good sign for the Dodgers as they prepare for Game 1 of the NL Championship Series on Friday on TBS.
