WASHINGTON (TNND) — From friendly matches in the park to championship-level play, pickleball has evolved into one of the most premier and popular sports for all ages.

A recent USA Pickleball annual growth report notes, "Pickleball continued to dominate the headlines in 2024, maintaining its status as the fastest-growing sport in America for the fourth consecutive year."

So, it is no surprise that the sport often intermingles with another racket sport, bringing some of the largest names from tennis to a new court.

Andre Agassi is a former world No. 1 tennis player and Grand Slam champion who's taking the leap to professional pickleball play. Agassi's name has recently become synonymous with not just tennis, but pickleball too, with appearances in the Pickleball Slam and an endorsement with popular pickler brand JOOLA.

Agassi will team up with teen pro Anna Leigh Waters, who, according to Tennis.com, is "highly regarded at being the greatest women's player of all time," to compete at the Minto U.S. Open Pickleball Championships in Naples, Fla.

Waters has 173 Professional Pickleball Association (PPA) titles across singles, doubles and mixed doubles matches, with 148 of those titles being gold.

Agassi and Waters will debut in the mixed doubles category in the tournament running from April 26 to May 3 at East Naples Community Park. The tournament is expected to draw more than 50,000 spectators.

“We’ve broken all records this year,” Ben Weinberger, U.S. Open tournament director, told a Cape Coral television station. “We have almost 3,500 competitors from all 50 states and 40 countries."

When announcing their partnership, Agassi had great praise for Waters' success in the sport.

It was very apparent that Anna Leigh was tired of winning. She’s right up there with the greatest ever in what she does and the idea of challenging myself to not screw things up for her is daunting," Agassi said.

Waters is the defending women's doubles champion at the U.S. Open.

Their first match is on Wednesday at noon EST. The tournament is airing on CBS Sports Network.
