The US Open swing is shaping up to be a summer of love as the game’s biggest names find themselves awash in good vibes and compliments.

It all began at the National Bank Open in Canada, as players received encouraging postcards from fans—or, in the case of Paula Badosa, a fellow player.

“I know who this is from,” said the Spaniard before reading a note from good friend Aryna Sabalenka.

Naomi Osaka was particularly moved by a note from one of her No. 1 fans.

“This is me being real,” admitted the four-time Grand Slam champion, “but whenever people tell me I’m their favorite player it’s like, honestly the most flattering thing ever. I always think there’s so many other players and it’s like, ‘Wow, you chose me out of all the other players? That’s crazy!’”

The players were then tasked with sending postcards of their own, and Venus Williams’ clearly won the day.

“To whom it may concern,” read the jokingly serious former No. 1. “Bet on yourself because you’re your best bet.”

As the field headed south for the Western & Southern Open in Cincinnati, the positivity kept flowing as players exchanged compliments with colleagues.

“Practicing next to Andrey Rublev and seeing how hard he hits the ball, it was funny because I was stopping to watch him practice and trying to hit my forehand that fast too,” said Emma Raducanu, who is in the midst of a phenomenal week after scoring back-to-back wins over Serena Williams and Victoria Azarenka.

“It sort of helped and I was hitting it bigger! Not Rublev big, though.”

While other players got similarly deep, Tommy Paul kept things hilariously simple when complimenting fellow New Balance athlete Coco Gauff.

“I always love the NB ‘fits she’s got on,” he said, causing the producer to laugh off-camera. “Are we supposed to go into detail? You were waiting and I felt so awkward!”

Here’s hoping the summer of love culminates with an unforgettable US Open.
