Bills Mafia must double as the Jessica Pegula fan club.
Pegula — heiress to Buffalo’s multibillion-dollar sporting empire — has yet to drop a set at this year’s U.S. Open, after the 31-year-old advanced to the quarterfinals with a 6-1, 6-2 victory over fellow American Ann Li inside Arthur Ashe Stadium on Sunday.
The 2024 U.S. Open runner-up apparently felt the love from her hometown.
“Do we have any Bills fans in here?” Pegula asked the crowd after her win.

“I mean, there’s so many Bills fans when I come here,” she continued. “I think it’s so cool that I’ve been able to take football fans and bring them into the tennis world. Because, in my Buffalo, there’s not really a lot of tennis. So that’s been really cool. And everyone kind of roots for me, so I feel like I’m basically part of the team and part of Bills Mafia, even when I’m out here on the tennis court. And I always feel that, I swear, every city I go to.
“Whether it’s Australia, here, the Middle East, Europe, wherever — I always run into Bills fans. It’s really, really cool. I’m hoping we have a great season, so that’s all I can say.”
Her parents, Terry and Kim Pegula, own the NFL’s Buffalo Bills, the NHL’s Buffalo Sabres, the AHL’s Rochester Americans and the Buffalo Bandits of the National Lacrosse League.
In his first three matches, Novak Djokovic showed vulnerability.
He dropped a few sets.
He wasn’t at his best.
Sunday night was a different story.
The 24-time Grand Slam champion and seventh seed had no trouble with Jan-Lennard Struff, cruising into the quarterfinals of the US Open with a 6-3, 6-3, 6-2 victory at Arthur Ashe Stadium.

The win sets up a blockbuster quarterfinal against American Taylor Fritz, the fourth seed.
Djokovic is undefeated in 10 meetings against Fritz.
This was Djokovic, 38, excelling on his serve (12 aces, no double faults), breaking Struff six times, winning a high percentage at the net (15 of 18 points) and tallying 33 winners.
The result was never in doubt, Djokovic racing out to a four-love lead in the first set to set the tone for the quick one-hour and 49-minute match.
Thievery has reportedly crept into the drama of the U.S. Open.
Romania’s Sorana Cirstea has claimed her singles trophy from the Tennis in the Land hard court tournament in Cleveland was stolen from her hotel room in New York while she was playing in the year’s final Grand Slam tournament, per the Associated Press.

She had pleaded for the trophy to be found from the hotel on Saturday night, which was two days after she was eliminated from the singles draw in Flushing, Queens.
Cirstea is staying at The Fifty Sonesta Hotel New York in Midtown Manhattan.
Looking to reach the quarterfinals of a Grand Slam tournament for the first time in her singles career, Taylor Townsend fell just short.
The 29-year-old American lost her way in a 6-1, 6-7 (13), 3-6 loss to Barbora Krejcikova on Sunday evening, blowing a one-set lead and eight match points inside a jam-packed Louis Armstrong Stadium.

Krejcikova will face another American in Jessica Pegula on Tuesday.
After a viral postmatch exchange with second-round opponent Jelena Ostapenko, in which the Latvian hurled insults across the net, Townsend quickly became the player of the tournament.
In her fourth-round match at Arthur Ashe Stadium, the world No. 4 American cruised to a 6-1, 6-2 win in just 54 minutes against fellow American Ann Li on a forehand winner down the line that came with a yell in victory.
The reigning U.S. Open women’s singles finalist is the first quarterfinalist of the 2025 U.S. Open where she will play either American Taylor Townsend or Czech Barbora Krejčíková on Tuesday.
