Yankees slugger Brett Gardner has reportedly asked a Bronx judge to keep a crazed fan — who calls herself the baseball player’s “future wife” — away from him and his family.

An attorney for Gardner filed an order of protection against Gina Devasahayam last week in Bronx civil court, according to NJ.com, which reported Monday that the Yankees want her banned from all MLB ballparks.

Devasahayam, 46, who says she’s the founder of an anti-aging biotechnology company, sued Gardner, the Yankees and MLB last year after she was booted out of Yankee Stadium during a playoff game in October.

“I request the Court to grant me access to the Stadium in accordance with MLB fan policy and also in accordance with ‘Significant other’ of MLB player Brett Gardner,” Devasahayam wrote in the lawsuit, according to the news outlet. “I am a Yankees fan and also the future wife of Brett Gardner.”

The Yankees have sought to get the lawsuit thrown out.

Before Devasahayam was turned away from Yankee Stadium, she tried to sneak into the visitors clubhouse at Oriole Park at Camden Yards in August to see Gardner, but was subsequently booted from the stadium.

Though Devasahayam and Gardner, 36, have never met, she has claimed in her lawsuit that the outfielder has hinted that he is interested in her.

Devasahayam says in the suit that a video of Gardner in the dugout shows that he “motions with his hip on the stairs as though he is having sexual intercourse with me,” according to NJ.com.

She also claimed that Gardner makes “a sad face” during home games when she does not attend, and that after “3 years of romancing online,” she started going to games “because I see that Brett desires this.”

A Twitter account for Devasahayam is riddled with references to Gardner.

On Valentine’s Day, she tweeted: “Happy Valentine’s day mi amor Gardy @Yankees.”

“Congrats Gardy on your renewed deal with @Yankees I look forward to seeing you soon!” a tweet from December reads.

An October tweet says: “I have never seen you angry at me Gardy, I will claim you play the role of my husband, that is my first right, my second right is to allow me inside the Stadium.”

During an interview with Devasahayam, an NJ.com reporter pointed out that Gardner is married to Jessica Clendenin.

“That is not of importance,” Devasahayam told the news outlet.

Devasahayam told NJ.com that the league is painting her as a “deranged rambling woman on the loose” and arguing that she is a “threat to order and safety.”

But she insists that Gardner wants her around, despite him filing an order of protection and despite the Yankees seeking to ban her from stadiums.

“You know, when he plays, he signals,” Devasahayam told the news outlet. “They have their own signals, first of all, for pitch type and all that. … And then there’s another thing called romantically and sexually signaling toward me. That is how our relationship has progressed because he has started sexually signaling toward me.”

The Yankees did not immediately respond to a request for comment by The Post on Monday.
