After the game, L.A. slugger Max Muncy claimed Neris yelled "F--- you" toward the Dodgers' dugout.
"He's blown about eight saves against us over the last two years," Muncy told Pedro Moura of The Athletic. "I guess he was finally excited he got one."
It was the latest in a string of run-ins between Neris and the Dodgers. During the second contest of the four-game set on Tuesday, Neris blew a one-run lead in the ninth inning by giving up a three-run home run to Matt Beaty. In the subsequent at-bat, Neris hit David Freese in the upper back with a pitch and was promptly ejected by home plate umpire Chris Conroy.
Neris earned a three-game suspension for the antics, which the right-hander is currently appealing.
"To look in our dugout and to taunt in any way, I think it's unacceptable." Dodgers skipper Dave Roberts said.
Entering Thursday, Neris had made two appearances against the Dodgers this season, allowing four runs while recording two total outs for one loss and one blown save.
Neris only made one appearance against the Dodgers in 2018, allowing one run on three hits while recording one out in a no-decision. In 2017, Neris went 2-for-3 in save opportunities against the Dodgers, surrendering five runs on six hits over 3 1/3 innings.
The 30-year-old had a career 8.49 ERA over 11 2/3 frames against L.A. coming into Thursday.
"The emotion of the series, you know," Neris told Scott Lauber of the Philly Inquirer. "It's a great win for my team and just I let my emotion get out. That's all I have to say about that."
