Alex Rodriguez’s girlfriend models date night look while watching the Yankees

Alex Rodriguez and girlfriend Jaclyn Cordeiro enjoy the last weeks of summer together.

Cordeiro showed off a sexy little black dress in a post on Instagram on Monday titled “Date Night,” in which the fitness enthusiast struck a series of poses in platform sandals and aviator sunglasses. She tagged designer Tom Ford in the caption.

Rodriguez, who was first linked to Cordeiro in October 2022, dropped a trio of fire emojis in the comments.

Shortly after sharing the “Date Night” post on her Instagram Stories, Cordeiro uploaded another slide on Monday of herself recording a Yankees game on a tablet while sitting by the water.

Cordeiro, 44, tagged Rodriguez, 48, in the post, which apparently showed the former hitter watching Monday’s 5-2 road win over the Nationals.

Rodriguez, who spent 12 seasons with the Yankees and won the 2009 World Series, returned to the Bronx on Saturday for the team’s Old-Timers’ Day.

“It’s my first time here and I’m excited to be back. I’m very proud of my time in New York and I’m very proud to be part of a championship team,” said Rodriguez, who hit 351 home runs and 1,096 RBIs and had a .283 batting average during his time in the pinstripes.

Rodriguez’s performance at Yankee Stadium came weeks after he and Cordeiro toured Europe on a dream summer vacation.

The couple was spotted taking a walk on the beach in Sardinia (Italy) at the end of July.

Rodriguez leaned on Cordeiro during his health struggle, telling The Post in April that “she was a good influence on me.”

“I’ve worked hard and tried to stay in shape and continue to try to copy some of her great work ethic and health and wellness practices,” Rodriguez said at the time.

Rodriguez made his relationship with Cordeiro public in December 2022.

They got together after his separation from fitness expert Kathryne Padgett.

Rodriguez was previously engaged to Jennifer Lopez.
