Aryna Sabalenka: Tragedy, Triumph, and No.1 Ranking

Few athletes have followed a Grand Slam title with a visit to their boyfriend’s grave, but Aryna Sabalenka carried that weight through the 2024 season and kept winning. The Belarusian powerhouse has turned personal grief into an unprecedented run at the top of women’s tennis, stacking four major titles while navigating a private life marked by sudden loss and new beginnings.

Age: 28 (born May 5, 1998) ·
Height: 5’11” (1.82 m) ·
Current ranking: World No. 1 (WTA) ·
Grand Slam titles: 4 (Australian Open 2023, 2024; US Open 2024; Wimbledon 2025) ·
Country: Belarus

“I’m just so happy to have my team here with me,” Sabalenka said after winning the 2024 Australian Open, reflecting on the support system that helped her through loss.

Key facts about the Belarusian star tell the story of a player who turned professional at 17 and reached world No. 1 by age 25.

The implication: Sabalenka’s statistical profile matches a player at peak physical maturity — tall, powerful, and already holding a dominant ranking at 28, the typical sweet spot for tennis longevity.

Is Aryna Sabalenka in a relationship?

• Sabalenka was in a relationship with Konstantin Koltsov from 2021 until his death in March 2024, as confirmed by Wikipedia (Spanish).
• She is currently dating Brazilian entrepreneur Georgios Frangulis, founder of Oakberry, according to Tennis Majors (WTA news outlet).
• There is no public evidence she ever dated a married man; her relationship with Koltsov was publicly acknowledged and he was not married at the time, as noted by Gala (French celebrity magazine).

Did Sabalenka date a married man?

No. The claim that Sabalenka dated a married man appears to originate from social media speculation. Gala’s profile states Koltsov was her partner, and neither the WTA nor Sabalenka herself has referenced any marriage on his part.

Who is Aryna Sabalenka’s partner?

As of 2025, Sabalenka’s partner is Georgios Frangulis, the founder of the acai bowl chain Oakberry, as reported by Tennis Majors. He has been spotted in her player box at tournaments including the 2025 Australian Open.

The trade-off: public scrutiny of her private life increased after Koltsov’s death, but Sabalenka has kept subsequent relationships low-profile — a tactical choice for someone whose ranking leaves no room for distraction.

What happened to Sabalenka’s husband?

• Konstantin Koltsov, Sabalenka’s long-term partner, died in March 2024 in Miami, Florida, at age 42, according to Wikipedia (biographical entry).
• His death was reported by authorities as an apparent suicide. The Miami Police Department investigated and found no foul play, as cited by Gala.
• Sabalenka referred to Koltsov as her “husband” in social media posts after his death, though they were not legally married, as noted by Tennis Majors.

“We ask that you respect the privacy of the family during this difficult time,” the Koltsov family said in a statement after his death, as reported by multiple outlets.

Who is Konstantin Koltsov?

Koltsov was a Belarusian professional ice hockey player who spent parts of three seasons in the NHL with the Pittsburgh Penguins from 2002-2006, and later played in the KHL, as detailed by Wikipedia. He and Sabalenka began dating in 2021 and lived together in Miami.

How did Konstantin Koltsov die?

Koltsov died on March 18, 2024, in Miami. The Miami-Dade Medical Examiner’s Office ruled the death a suicide. Sabalenka continued playing in the Miami Open the following week, a decision she later said was “the hardest thing I’ve ever done,” as reported by Gala.

The pattern: Sabalenka’s response to Koltsov’s death — staying on tour, winning tournaments — mirrors her response to earlier adversity. She won the Australian Open just weeks before his death and the US Open months after, demonstrating a compartmentalization that coaches describe as both a strength and a concern.

Does Sabalenka have any children?

No. Aryna Sabalenka does not have any children as of 2025, according to Wikipedia (biographical entry). She has not publicly addressed plans for motherhood.

The catch: fans who compare her to fellow WTA players who balanced motherhood and tennis (like Serena Williams or Victoria Azarenka) may see Sabalenka’s child-free status as a strategic advantage — uninterrupted training and travel at her peak earning years.

Is Sabalenka a US citizen?

• No. Sabalenka is a Belarusian citizen and has not acquired US citizenship, as stated by WTA Official (players database).
• She resides part-time in Miami, Florida, for training and tournament access, but holds Belarusian nationality, per Roland-Garros (official tournament site).

What is Aryna Sabalenka’s nationality?

Sabalenka is a Belarusian national, born in Minsk. She has not publicly indicated plans to pursue US citizenship, though her long-term residence in Florida and English fluency have fueled fan speculation, as noted by Tennis Majors.

The implication: Sabalenka’s residency status remains a topic of speculation, but her competitive focus stays on the court.

Who is the richest woman in tennis?

• The richest woman in tennis by net worth is Serena Williams, with an estimated $300 million from prize money and endorsements, per Gala (celebrity finance analysis).
• The “billionaire daughter” often mentioned in tennis circles is Jessica Pegula, whose parents own the Buffalo Bills, with a family net worth exceeding $7 billion, as noted by Tennis Majors.

Who is the billionaire daughter in tennis?

Jessica Pegula, the world No. 3-ranked American, is the daughter of Terry and Kim Pegula, owners of the Buffalo Bills, with a family net worth exceeding $7 billion.
