World No. 1 Jannik Sinner is chasing history at the US Open 2025, showing both resilience and dominance as he defends his title. His on-court brilliance has made headlines, but so has his personal life—with the Sinner Kalinskaya breakup earlier this year and new rumors involving Danish model Laila Hasanovic.
Jannik Sinner’s US Open Progress
Round 1: Commanding Start
The Jannik Sinner US Open 2025 campaign began with a resounding 6-1, 6-1, 6-2 win over Vit Kopriva. The Italian star never lost serve and converted seven of ten break points, setting the tone for his title defense.
Round 2: Smooth Progression
He followed up with another straight-sets win over Alexei Popyrin, 6-3, 6-2, 6-2, proving his form remains sharp.
Round 3: A Resilient Rescue
In a tougher test, Sinner dropped the first set to Denis Shapovalov before storming back for a 5-7, 6-4, 6-3, 6-3 victory. His ability to rally from 0-3 down in the third set showed why he is the sport’s leading man. This Sinner US Open progress keeps him on track for another deep run at Flushing Meadows.
Season Context & Motivation
So far in 2025, he has already won the Australian Open and Wimbledon, while finishing runner-up at the French Open. If he reaches the US Open final, he would join a select few to play in all four Slam finals in a single year.
Off-Court Spotlight: Jannik Sinner Girlfriend Talk
Off court, the Jannik Sinner girlfriend chatter has kept social media buzzing.
The Sinner Kalinskaya Breakup
His relationship with Russian player Anna Kalinskaya ended in May 2025. The Anna Kalinskaya Jannik Sinner story concluded with both admitting that the demanding men’s and women’s tour schedules made it too hard to continue.
Since the Sinner Kalinskaya breakup, Kalinskaya has focused solely on her own career and has not been linked to a new partner.
The Laila Hasanovic Sinner Rumors
Meanwhile, fans have connected Sinner with Danish model Laila Hasanovic. Courtside appearances and a phone wallpaper incident sparked the Laila Hasanovic Sinner rumors, though he has avoided confirming anything, saying only that he is “in love.”
Hasanovic herself has been tight-lipped about disclosing her partner, as is evident from the Instagram post below, where she shared a serene update without hinting at any relationship details.
Anna Kalinskaya’s US Open 2025 Run
While much of the focus has been on the Sinner Kalinskaya breakup, Anna Kalinskaya has been making strides on the court. At the US Open 2025, she advanced to the third round before meeting world No. 2 Iga Swiatek. Kalinskaya put up a strong fight but eventually lost in straight sets, 6-7(2), 4-6.
This result marks her second consecutive third-round appearance at Flushing Meadows and underlines her steady improvement on the tour. Even with personal changes off court, her focus on tennis remains clear.
She also reflected on her form earlier in the summer with an Instagram post after reaching the final in Washington, DC, writing: “What a week it’s been in DC 🙂↔️ not the result I wanted but still making the final is a nice feeling 💪🏽🥈 soon ✈️ 🇨🇦.”
Looking Ahead: What’s Next?
| Stage | Opponent | Challenge |
|---|---|---|
| Round of 16 | Alexander Bublik | One of the few players to beat him this season; unpredictable, dangerous, and a genuine test. |
Final Thoughts
Sinner remains the headline act in tennis news, combining excellence on the court with constant attention off it. The Sinner personal life angle has become part of the narrative, but it’s clear his primary focus is winning matches.
The breakup with Kalinskaya and rumors with Hasanovic highlight how tough it is for athletes to balance careers and relationships. Players deserve privacy, but with paparazzi following top stars around the clock, that balance is fragile.
For now, Jannik Sinner is fully focused on chasing another US Open crown—while the world continues to watch both his tennis and his private journey.
