The 26-year-old, 11-time Grand Slam champ will learn the game from current PokerStars pros and help promote online poker in Spain following the recent awarding of government licenses to online poker sites.
“It’s no secret that I love to compete," Nadal said in a release, "and try my very best in everything, whether that’s tennis, golf or video games.
“When I discovered the game of poker, I chose to join PokerStars because they understand what it takes to be the best and associate themselves with the qualities of champions.
"I’m very happy to be working with them.”
Nadal will stick to tennis for most of the summer but when his schedule frees up in the fall he'll start representing PokerStars in online poker tournaments, appear in more advertising campaigns and play in charity poker events.
Fans can join Rafa on his poker journey on his own page at PokerStars and Twitter followers can use the #nadalpoker hashtag to send messages his way.
