Pete Alonso’s dream rookie season will end Sunday, but he isn’t going quietly.

The Mets first baseman cleared the left-field fence at Citi Field in his first at-bat in the Mets’ 4-2 win over the Braves on Friday night for homer No. 52, tying him with Aaron Judge for the MLB rookie record. Judge hit 52 homers for the Yankees in 2017.

Alonso, who went 1-for-3, smashed a line drive off Dallas Keuchel that hit a blue retaining wall behind the left-field fence. Alonso thrust both arms into the air as he rounded first base.

Already this season, Alonso had broken Cody Bellinger’s NL rookie record for homers (39) and shattered the previous franchise single-season mark of 41, shared by Todd Hundley and Carlos Beltran.

Alonso began the night as the MLB leader in homers and is attempting to become the first Mets player to wear that crown. Alonso’s 119 RBIs tied Wally Berger in 1930 for the second-most by a National League rookie. Albert Pujols established the record with 130 RBIs as a Cardinals rookie in 2001.

Marcus Stroman allowed two runs on six hits and struck out eight over six innings to get the win.

Manager Mickey Callaway was asked whether he could envision himself as a pitching coach at 82 years old like Phil Regan, who is filling the role on an interim basis for the Mets.

“When I am 82?” Callaway said. “I don’t even picture myself being alive.”

Robinson Cano was on the bench for a scheduled day off, a night after he was drilled in the hand/wrist. Callaway expects Cano back in the lineup on Saturday.

How does the Braves’ young nucleus compare with that of the Mets?

“They have a young core that came up together and play very well together,” Callaway said. “I feel we have that same young core, but ours are probably a little bit older. They are still young, but I think we can compete with anybody when we put the sum of ours parts together.”
