Paging Luis Castillo.

In a play reminiscent of the former Mets second baseman’s infamous error in the Subway Series, rookie Carson Benge made an ugly miscue in the top of the seventh with the Mets up by three runs over the Yankees at Citi Field.

After Aaron Judge opened the inning with a double off Brooks Raley, Cody Bellinger sent a fly ball to right field, where Benge was ready to make a routine catch.

But Benge, who had made some highlight-worthy plays and some head-scratchers, dropped the ball for a two-base error that allowed Judge to score and Bellinger to reach second.

It gave the Yankees a big chance to spark a rally with the Mets already reeling in the wake of Clay Holmes’ injury on Friday night.

But former Yankees reliever Luke Weaver entered and struck out Amed Rosario and Trent Grisham before Anthony Volpe grounded out with the bases loaded to end the inning.

That turned out to be the key moment in the Mets’ 6-3 win over their crosstown rivals. Game 3 of the Subway series is on Sunday.
