Meet the newest addition to Aryna Sabalenka's entourage: her puppy, Ash

Aryna Sabalenka treats her longtime support team, which includes coach Anton Dubrov and physiotherapist Jason Stacy, like family when they travel around the globe-trotting tennis tour.

But on the eve of the BNP Paribas Open, the world No. 1's inner circle is expanding—and this new teammate comes with floppy ears and four legs.

Sabalenka revealed her new Cavalier King Charles spaniel, a good boy named Ash, on Monday to her nearly 5 million followers on Instagram. The brown-and-white pup can be seen in the series of snapshots cuddling Sabalenka and her boyfriend Georgios Frangulis in various locations, including in the car and on-site at the Indian Wells Tennis Garden.

The newest member of "Team Tiger" quickly built a fan club.

Less than an hour after Ash's hard launch into the world, Sabalenka's post had already racked up more than 50,000 likes.

But Ash isn't the only four-legged friend enjoying the tour's annual visit Tennis Paradise.

Defending champion Mirra Andreeva, who beat Sabalenka in three thrilling sets in last year's final, is back at the site of her triumph with Rassy in tow.

The 18-year-old's dream of becoming a dog mom came true in November after nearly two years, with her mom famously first promising her a dog as a reward for reaching the Top 20 in 2024.

Stay tuned for more dispatches from the BNP Paw-ribas Open as more players hit the practice court ahead of the first day of main-draw play later this week.
