Mattingly replaced Yasiel Puig with Skip Schumaker who finished the game in the outfield in Puig's place.
Puig showed no effort in the first inning of breaking up a double play, and in the third inning after striking out, slammed his bat in frustration.
Puig and Mattingly after the game had a closed door, one-on-one meeting regarding his antics during the game.
"I wanted to finish the game, but I agreed with the explanation," Puig said. "The meeting went well. We talked about what every player needs to do to prepare for every pitch."
The Dodgers wasted no time offensively, when Hanley Ramirez knocked out a solo home run deep to left center for the 1-0 lead in the first inning.
Andre Ethier crushed another home run off of Edwin Jackson in the fourth inning for the 2-0 lead.
Jackson committed an error in the fifth inning that allowed Juan Uribe to score after Nolasco bunted into a fielder's choice play.
Schumaker who replaced Puig, connected n an RBI single that scored Tim Federowicz for the 4-0 lead.
Kenley Jansen pitched three consecutive strike outs to end the game in the ninth inning.
This was not the first time that Puig was benched for questionable behavior. While on the road in Miami, Mattingly benched him for undisclosed reasons.
Nolasco's bright performance was dimmed by the Puig discipline.
"What he did today wasn't acceptable," said Nolasco on Puig. "He's young, he's going to have to learn. It's not going to be a distraction. He's going to help this team way more than what he did today."
Edwin Jackson (7-14) gave six hits and two runs in the loss. "That's a tough lineup, and the pitching staff is doing well, too," Jackson said.
The Dodgers get ready after a day off on Thursday, for a weekend series against the San Diego Padres. Puig is scheduled to be in the line up for that series according to Mattingly.
