Arrieta pitched neatly into the ninth inning, Scott Kingery and Cesar Hernandez hit solo homers and the Philadelphia Phillies beat the New York Mets 3-2 Wednesday.
Hector Neris blew a 95 mph fastball past Keon Broxton with a 3-2 count and the bases loaded for the final out and his second save.
Arrieta (3-1) allowed two runs and six hits, inducing three double-play grounders. The veteran righty has pitched like the guy who won the 2015 NL Cy Young Award with the Cubs. He's thrown at least seven innings in three straight starts and has a 2.25 ERA after going 10-11 with a 3.96 ERA in his first season in Philadelphia last year.
"He has a different mindset," Phillies manager Gabe Kapler said. "He understands everybody is looking to him for leadership and he's taken the bull by the horns."
The Phillies, off to an 11-6 start, are counting on Arrieta, especially since All-Star Aaron Nola is struggling and Nick Pivetta was demoted to the minors after opening the season as the No. 2 starter.
"I feel good and I've been able to spin the ball well," Arrieta said. "The timing of my delivery now is really good."
Zack Wheeler (1-2) gave up three runs and five hits in seven innings.
Arrieta took the mound to start the ninth aiming for his first complete game since tossing a no-hitter on April 21, 2016, against Cincinnati. But he exited after Pete Alonso reached on an infield single that glanced off Arrieta to begin the inning.
Adam Morgan entered and hit Robinson Cano in the back with a fastball. After Morgan retired Michael Conforto on a fly to right, Neris struck out J.D. Davis. But Amed Rosario reached on an infield single that drove in a run and Neris hit pinch-hitter Wilson Ramos near his left elbow to load the bases.
With the crowd standing and cheering, Neris then struck out Broxton and pumped his fist jumping off the mound in celebration.
Maikel Franco's sacrifice fly in the second gave the Phillies a 1-0 lead.
Kingery hit an opposite-field drive out to right-center for his second homer in two games to give the Phillies a 2-0 lead in the fifth.
Hernandez drove his second homer into the right-field seats in the sixth to make it 3-0.
Conforto connected in the seventh, launching his fifth homer inside the right-field foul pole to cut it to 3-1. He has 16 homers and 46 RBI in only 51 career games against the Phillies.
"We had opportunities all game and didn't come up with enough runs," Conforto said. "We have to do more. We have to put it all together."
The Phillies have lost the season series to the Mets seven straight seasons, but took two out of three to start this year. The teams meet again in New York next week.
