MIAMI — A.J. Ewing’s late-summer siesta at the plate might finally be behind him. 

A day after collecting only his second multihit game over the past month, the rookie went a step further with a 3-for-5 performance that included three RBIs in the Mets’ 9-4 victory over the Marlins on Monday. 

Did Ewing change his approach following an August in which he produced a .463 OPS? 

“A little bit,” Ewing said. “I would just say that I am not chasing results and kind of sticking to an approach and a plan and just being pitch to pitch.” 

Ewing’s two-run double in the fifth inning extended the Mets lead to 7-4 and was among the big hits of the 16 the Mets collected. Ewing also delivered an RBI single later in the game. 

“The at-bats are outstanding,” interim manager Andy Green said. “He’s hitting the ball all over the field. He’s hitting with authority.” 

Ewing’s only blemish on this day was getting picked off first base in the third inning. 

“He got a little far off the base,” Green said. “But he can apply so much pressure with his speed, so getting him back on the bases really causes our offense to churn.”

Robert Stock will start Wednesday’s series finale, according to Green. The right-hander pitched in relief Friday — facing two batters — after his best career start four days earlier, when he pitched 5 ¹/₃ scoreless innings against the Rays. 

Reed Garrett, who is rehabbing from internal brace elbow surgery, will throw from a mound Tuesday in front of team officials. The right-hander has spent most of this season rehabbing in Port St. Lucie. 

Jared Young was on the bench for a second straight game after fouling a ball off his foot Saturday. Brett Baty started at first base. 

Justin Hagenman was optioned to Triple-A Syracuse to create roster space for Jonah Tong.
