Luisa Stefani

Luisa Veras Stefani (born 9 August 1997) is a Brazilian professional tennis player, and the first Brazilian woman to reach the WTA top 10. She reached the milestone on 1 November 2021 when she rose to world No. 9 in doubles. On 20 May 2019, she reached a career-high WTA singles ranking of 431. She had a career-high combined junior ranking of No. 10, on 30 March 2015.

She won the mixed-doubles competition at the 2023 Australian Open with Rafael Matos, becoming the first Brazilian pair to win a Grand Slam title.

Stefani is a bronze medalist in women's doubles from the 2020 Tokyo Olympics. Representing Brazil, she partnered with Laura Pigossi to defeat Veronika Kudermetova and defending gold medalist Elena Vesnina in the bronze medal match. Stefani and Pigossi were only granted entry to the Olympics one week before the 2020 Games opened, with Stefani ranked world No. 23 in the doubles ranking and Pigossi at No. 190, and had played together once, a defeat at the 2020 Fed Cup, and yet became the first Brazilians to obtain an Olympic tennis medal, surpassing the performance of Fernando Meligeni that took 4th place in men's singles in 1996. During the campaign, they saved eight match points: four in the bronze medal match and another four against Czech players Karolína Plíšková and Markéta Vondroušová in the round of 16.

Professional career
At the age of 14, Stefani's family moved to the United States, where it was hoped she would develop herself better in tennis. She started training at Saddlebrook Tennis Academy, and eventually reached two junior Grand Slam semifinals in doubles: the 2014 French Open and the 2015 US Open. As she attended Pepperdine University, Stefani was ranked as high as No. 2 in the ITA rankings, and was also named the 2015 ITA National Rookie of the Year, having compiled a 40–6 record in her freshman season and reached the semifinals of the 2016 NCAA Singles Championships, where she lost to eventual champion Danielle Collins. Stefani made her WTA Tour main-draw debut at the 2015 Brasil Tennis Cup where she received a singles main-draw wildcard.

2019
Until 2019, Stefani tried to play both singles and doubles. The doubles kept being more productive, and once an invitation to make her tour debut in the 2019 Monterrey Open with Giuliana Olmos led to the semifinals and a ranking increase, she decided to stop playing singles to have more chances at appearing in bigger events. Soon afterward, Stefani made her Grand Slam main-draw debut at French Open, partnering Australian Astra Sharma in doubles.

In September, with Hayley Carter as partner, she reached the first WTA doubles final at the Korea Open and, the following week, won the first WTA Tour title at the Tashkent Open.

At the Italian Open, she reached the semifinals, losing only to the top seeds. In October, she entered her first Premier final in Ostrava, playing with Gabriela Dabrowski.

2021: Olympic bronze medal, WTA 1000 title, world No. 9 & injury

They beat Russians Elena Vesnina and Veronika Kudermetova after saving four match points in the final super tiebreak. Pigossi and Stefani became the first Brazilians in history to obtain an Olympic medal in tennis, surpassing Fernando Meligeni's campaign that took 4th place in 1996.

Following the Olympics, seeded fifth, Stefani won her first WTA 1000, partnering Dabrowski, at the Canadian Open avenging their loss in the Silicon Valley Classic final to Darija Jurak and Andreja Klepač.

Also during the Australian Open, Stefani and Brazilian partner Rafael Matos were crowned champions, after defeating the Indian duo of Sania Mirza and Rohan Bopanna in straight sets. It was her first Grand Slam title and also the first for a Brazilian pair at a major.

Along with Zhang Shuai, Stefani won the WTA 500 in Abu Dhabi, returning to the top 30 in doubles.
