Caroline Wozniacki is one of ten players making a comeback at the 2023 US Open

Some are back from retirement, like Caroline Wozniacki, Barbora Strycova and Kevin Anderson. Others are rounding back into form after long-term injuries, including the likes of Jennifer Brady, Gael Monfils, Alexander Zverev, Kei Nishikori, Milos Raonic and Wimbledon champion Marketa Vondrousova. And we can't forget Elina Svitolina, who returns after she and Monfils welcomed their first child last year.

A US Open finalist in 2009 and 2014, Wozniacki announced her return from retirement less than two months ago in a Vogue essay. The 33-year-old retired following the 2020 Australian Open and has had two children since then with former NBA star David Lee.

The 2018 Australian Open women's singles champion made a winning return to professional tennis in Montreal, where she beat Aussie Kimberly Birrell, and enters New York with three matches under her belt.

"I think the more I play, the better it's going to be for me," Wozniacki said after losing to Wimbledon champion Marketa Vondrousova in Canada. "I think it's a great learning curve, and I'm happy that I know where I am, and I don't feel like I'm that far away from where I want to be."

After making her Grand Slam breakthrough on home soil by reaching the 2020 US Open semis, Brady backed it up with a run to the 2021 Australian Open final. She broke into the WTA's Top 15 and made her Olympic debut that summer in Tokyo, but suffered a major knee injury just before the 2021 US Open at the Cincinnati event-a devastating blow that kept her out of action for nearly two full years.

Brady returned to the WTA Tour this summer. She quickly notched first-round singles wins in Washington DC and Montreal, saving two match points against Jelena Ostapenko in Canada. The American entered the US Open field with a protected ranking.

The husband-and-wife duo return to the US Open as parents, having welcomed their first child in October.

Both fan favorites missed out on four majors in a row beginning with Roland Garros last season; Monfils sidelined with heel and foot injuries, and Svitolina absent due to her pregnancy. Monfils made his comeback this season at Indian Wells, but had to wait until Roland Garros for his first tour-level win. A quarterfinal run in Montreal and a third-round showing in Cincinnati, with three Top 20 wins across the two events, provide the perfect on-ramp for the 36-year-old's US Open return.

Svitolina returned in February and, in addition to winning a WTA 250 in Strasbourg in May, the Ukrainian saved her best results for the majors. The 28-year-old reached the Roland Garros quarterfinals and the Wimbledon semis, matching her best runs at both Slams. She has enjoyed similar success at the US Open in recent years, reaching the 2019 semis and the 2021 quarters in her past two appearances.

Zverev was playing some of the best tennis of his career when he suffered a gruesome ankle injury during his 2022 Roland Garros semifinal against Rafael Nadal. After sitting out the rest of the year, the German has steadily built up his form in 2023. This year, he's reached six semifinals, including at Roland Garros and last week in Cincinnati.

The 26-year-old claimed his 20th tour-level title on home soil in Hamburg this July without dropping a set. It was his first singles crown since won the 2021 ATP Finals.

The 2014 US Open finalist missed the entire 2022 season following hip surgery, then suffered a bad ankle sprain during his preparations for 2023. The Japanese star said he almost thought about retirement following the second setback, but he persevered and made his return this June on the ATP Challenger Tour, where he won his first tournament back in Puerto Rico.

Nishikori notched two wins in Atlanta this summer, his lone tour-level event of the season prior to the US Open, but pulled out of Washington DC this month with a left knee injury.

After a wrist surgery kept her out of the last three majors of 2022, Vondrousova returns to the US Open as a Grand Slam singles champion following her surprise Wimbledon run. The Czech defeated last year's US Open runner-up Ons Jabeur in the London final to became the first unseeded Wimbledon champion in the Open Era and the event's lowest-ranked winner in the Open Era at world No. 42.

She returns to New York as a Top 10 player with a career-high WTA ranking of No. 9.

A series of injuries, beginning with an Achilles problem, kept Raonic sidelined from July 2021 to June 2023. The Canadian has played three tournaments in a measured comeback, advancing to the second round at Wimbledon and notching a Top 10 win against Frances Tiafoe in Montreal.

The 37-year-old Czech retired in May of 2021 and gave birth to her first child during her time away from the game. She returned this April in Madrid and made a major splash at Wimbledon, winning her second women's doubles title alongside Hsieh Su-wei-with whom she also won the London doubles crown in 2019.

The 2017 US Open finalist announced his comeback from retirement in July and enjoyed a successful return in Newport, reaching the quarterfinals. In the New York qualifying draw, the former world No. 5 played in his third event since returning to the ATP Tour as he bids for a 12th US Open main-draw appearance.
