Derek Jeter and Alex Rodriguez thought they were going to be talking about a charity event during a CNBC interview on Tuesday, but instead, they were thrown a few unexpected curve balls.

Rodriguez and Jeter, Yankees teammates for 10 years and stock traders for a day at a BTIG global financial services company’s “Charity Day” in midtown, talked on “Squawk Alley” about their foundations and how they believe baseball could evolve.

But that wasn’t really what CNBC reporter Bob Pisani wanted to chat about. He was more interested in the A-Rod-Jeter relationship, Jeter’s interest in owning the Marlins and A-Rod’s love life with Jennifer Lopez.

“This is a treat to see you guys together. You guys are friends now?” Pisani asked an annoyed Rodriguez and Jeter, at the BTIG offices.

It has been well documented that the retired Yankees captain and the steroid-tainted Rodriguez have had a rough relationship dating back to when A-Rod dissed Jeter in a 2001 Esquire magazine interview which strained their previously close friendship.

“Shortstop, third base. This is exactly how we were back in the day,” said Rodriguez, desperately hoping the stock answer would stop the line of questioning.

But Pisani was having none of it.

“The press made a little thing about the back-and-forth between you two. Was that real?” asked Pisani.

“You’re bringing up stories from about 20 years ago, huh?” Jeter said. Rodriguez then chimed in: “History Channel,” mocking Pisani’s CNBC employer.

The dig didn’t stop Pisani, however.

“We were going to talk to you about the charity events, but you sort of moved everything around here with what happened [Monday] night at the Met, the gala,” Pisani said. “People were talking about it.”

“Wow,” Rodriguez said. “This interview is going all types of places. We had a great time [Monday] night. It was a celebration of art and fashion. And I was looking for my boy Derek, but he wasn’t there this year.”

But that wasn’t enough for Pisani, who pressed: “You showed up with J.Lo, of course.”

“What channel is this?” asked Jeter in mock surprise. “E! Channel,” said Rodriguez.

“People want to know,” Pisani said.

“That’s great,” a peeved Rodriguez said.

If Jeter thought he was off the hook, he was wrong. Pisani questioned the soon-to-be Hall of Famer about his interest in buying the Marlins. Jeter is reportedly a part of a group — with former Florida governor and presidential candidate Jeb Bush — to buy the Marlins from owner Jeffrey Loria, who is looking to sell the team.

Baseball commissioner Rob Manfred said last week that two groups — not just Jeter’s — are bidding for the Marlins.

“Now you’ve been in the news recently. Not at the Met Gala, but your interest in buying the Marlins,” Pisani said.

“There’s absolutely nothing to add to that,” Jeter said. “I think the media ran with a story.

“We’re here today for the BTIG Charity Day.”

“But 1.3 billion — a lot of money to buy a big league baseball team. You’re going to be involved in that if we get the deal done?” Pisani asked Jeter.

“Like I said, we’re here for the charity event today,” Jeter said. “We’re not here to talk about anything else.”
