Ashleigh Barty, Australian tennis player
Ashleigh Barty (born 24 April 1996) is an Australian retired professional tennis player and cricketer. She was the second Australian tennis player to be ranked No. 1 in the world in singles by the Women's Tennis Association (WTA) after fellow Indigenous Australian Evonne Goolagong Cawley, holding the ranking for 121 weeks overall. She was also a top-10 player in doubles, having achieved a career-high ranking of No. 5 in the world. Barty is a three-time Grand Slam singles champion, and the reigning champion at Wimbledon and the Australian Open. She is also a Grand Slam doubles champion, having won the 2018 US Open with CoCo Vandeweghe. Barty won 15 singles titles and 12 doubles titles on the WTA Tour.

Born in Ipswich, Queensland, Barty began playing tennis at the age of four in nearby Brisbane. She had a promising junior career, reaching a career-high ranking of No. 2 in the world after winning the 2011 Wimbledon girls' singles title. As a teenager, Barty had early success in doubles on the WTA Tour in 2013, finishing runner-up at three Grand Slam doubles events with veteran Casey Dellacqua, including at the 2013 Australian Open while 16 years old. Late in the 2014 season, Barty decided to take an indefinite break from tennis. She ended up playing cricket during this hiatus, signing with the Brisbane Heat for the inaugural Women's Big Bash League season despite having no formal training in the sport.

Barty returned to tennis in early 2016. She had a breakthrough year in singles in 2017, winning her first WTA title at the Malaysian Open and rising to No. 17 in the world despite having never been ranked inside the top 100 before her time off. She also had another prolific year in doubles with Dellacqua, culminating in her first appearance at the WTA Finals in doubles. Barty then won her first Premier Mandatory and Grand Slam tournament titles in doubles in 2018 before accomplishing the same feat in singles in 2019, highlighted by her victory at the 2019 French Open. Barty won five more titles in 2021, including a second major singles title at the 2021 Wimbledon Championships and two WTA 1000 titles. With her title at the 2022 Australian Open, she won a major in singles on all three surfaces. Barty has also led Australia to a runner-up finish at the 2019 Fed Cup and won a bronze medal in mixed doubles at the Tokyo Olympics in 2021.

Barty was an all-court player with a wide variety of shots. Despite her short stature for a professional tennis player, she was an excellent server, regularly ranking among the WTA Tour's leaders in aces and percentage of service points won. She serves as the National Indigenous Tennis Ambassador for Tennis Australia. Barty announced her retirement from tennis in March 2022, two months after her Australian Open title and still ranked No. 1 in singles at the time, having held the ranking for all but four weeks between June 2019 and April 2022 when she will relinquish the ranking. Her 114 consecutive weeks at No. 1 (not including when rankings were frozen between March and August 2020 due to the COVID-19 pandemic) is the fourth-longest streak in WTA history.
