Caroline Wozniacki

Caroline Wozniacki is a Danish professional tennis player. She was ranked world No. 1 in singles for a total of 71 weeks, including at the end of 2010 and 2011. She achieved the top ranking for the first time on 11 October 2010, becoming the 20th player in the Open Era and the first from a Scandinavian country to hold the top position. In 2018, she became the first Dane to win a major singles title, at the Australian Open.

Known for her footwork and defensive abilities, Wozniacki won 30 WTA Tour singles titles (including six in both 2010 and 2011, the most in a year by a WTA player from 2008–2011) and two doubles titles. A junior major champion, she won the 2006 Wimbledon girls' singles title over Magdaléna Rybáriková and was voted the WTA Newcomer of the Year in 2008. Before her victory at the 2018 Australian Open over Simona Halep, she had reached two major finals at the US Open, falling to Kim Clijsters in 2009 and to Serena Williams in 2014. Wozniacki also won the season-ending WTA Finals in 2017, beating Venus Williams, after previously finishing runner-up to Clijsters at the event in 2010. Other career highlights include winning three Premier Mandatory and three Premier 5 titles, reaching four major semifinals (the 2011 Australian Open and the 2010, 2011 and 2016 US Opens), three major quarterfinals (the 2012 Australian Open and the 2010 and 2017 French Opens), and the quarterfinals at the 2012 London Olympics.

Wozniacki retired on 24 January 2020, following a third-round loss at the Australian Open. She became an ESPN commentator in 2022. In June 2023, Wozniacki announced in a first-person essay in Vogue her return to pro tennis, starting in the North American summer hard court swing. She accepted main draw wild cards for two big warm-up events in Montreal and Cincinnati before heading to New York for the US Open. At the US Open, Wozniacki reached the fourth round, where she lost to later winner Coco Gauff in three sets.
