The Red Sox ended up sweeping the Yankees at the beginning of August, and Rodriguez had to pay his dues by working at Wahlberg's own Wahlburgers restaurant.

"It was time to me to hold up my end of the deal and report for duty to the @Wahlburgers location near Fenway Park," Rodriguez wrote in an Instagram post.

Rodriguez said he did anything and everything, between greeting customers, flipping burgers, clearing tables and mopping floors.

The former Rangers and Yankees star posted video of his day on Instagram, just in case any future employers needed to see examples of his work.

"What I thought was going to be a tough day turned out to be a day I really enjoyed," Rodriguez wrote. "The people in New England were incredibly hospitable. I'm sure they were in a great mood with both the Red Sox at home today and the @Patriots opening their season here, too."

Rodriguez said he was grateful for how he was treated, and even got some employee discounts on some food while he was there.

"Now, I need to double down and hopefully get Mark in the Bronx sometime," Rodriguez said.
