Rafael Nadal has found an unlikely doubles partner…

The 31-year-old Spanish tennis star joined forces with longtime rival Roger Federer to win a doubles match in the new Laver Cup on Saturday.

Nadal and Federer teamed up for the first time to defeat Sam Querrey and Jack Sock 6-4, 1-6, 10-5 in the team event between Europe and the rest of the world.

“It was unbelievable,” Nadal said.

The inaugural Laver Cup is taking place at Prague’s O2 Arena on an unusual black hard court.

Alexander Zverev, Marin Cilic, Dominic Thiem and Tomas Berdych also form the European team.

John Isner, Nick Kyrgios, Denis Shapovalov and Frances Tiafoe play for the world.

Europe needs two more victories from Sunday’s four games to win.
