Dayana Yastremska

Junior career

Her career-high junior ranking was No. 6 and, as a 15 year old, she reached the quarterfinals of the junior girls' singles event and the final of the girls' doubles event at the 2016 Australian Open. She followed that up by reaching the final of the girls' singles at Wimbledon, losing to Anastasia Potapova of Russia in straight sets.

2016: Senior debut

After winning her first ITF title in Brazil, Yastremska made her WTA main-draw debut at the İstanbul Cup, where she received a singles wildcard. However, she lost a close first-round match against sixth seed Nao Hibino 6–2, 4–6, 3–6.

2017: First WTA win

Yastremska won her first career WTA match at the İstanbul Cup, where she beat the eighth seed Andrea Petkovic 3–6, 6–0, 6–3. She then on went on to win her second-round match 6–1, 6–4 against Anna Kalinskaya, but lost her quarterfinal against Jana Čepelová in three sets after leading 5–2 in the second set and serving for the match. Later in the season, she and Potapova teamed up to win their first ITF doubles title together, in Prague. She followed that up with her most important win yet, in the ITF tournament in Dunakeszi, Hungary, before finishing runner-up to Belinda Bencic in the Neva Cup in Saint Petersburg.

2018: Top 100 debut, first WTA title

Yastremska made her senior Grand Slam debut in the qualifying rounds of the Australian Open, where she won her first match against 17th seed Misaki Doi, but was knocked out in the second round by Alexandra Dulgheru, 7–6(6), 6–0. She then qualified for the main draw in Acapulco, but injured an ankle during her first round match against Monica Puig and had to retire.

Her next significant tournament was in Cagnes-sur-Mer, France, in May. She had to qualify for the main draw, and went all the way to the final, where she lost in straight sets to Rebecca Peterson. She also reached the singles final in the equivalent tournament in Ilkley, Yorkshire, going down in three sets to qualifier Tereza Smitková. Yastremska was serving for the first set at 5–4 but couldn't hold on, the set eventually going to a tie-break. Although she won the second set, the third also went to a tie-break after both players dropped serve twice. Down 3–4, Smitková was able to force Yastremska into errors as she won four consecutive points to take the match.

The following week Yastremska was in Roehampton, attempting to qualify for Wimbledon. She beat Magdalena Fręch in the first round of qualifying, but was then beaten in the second round by Barbara Haas. She moved on to Rome a few days later, and the ITF Tiro A Volo tournament, where she was dominant throughout the preliminary rounds and destroyed Anastasia Potapova in the final, winning 6–1, 6–0, in just 45 minutes. In Budapest the following week she reached the semifinals of the 2018 Hungarian Pro Circuit Ladies Open, losing to Ekaterina Alexandrova in three sets.

After a strong summer on the ITF Pro Circuit, Yastremska became the first woman born in the 2000s to crack the top 100 on the WTA rankings, reaching No. 100 in July 2018.^[1]

In October, she competed in the International event at Hong Kong. She defeated Fanny Stollár, Zheng Saisai, Kristína Kučová, and Zhang Shuai to reach her first final on the WTA circuit. There she faced sixth seed Wang Qiang, defeating her decisively 6–2, 6–1 to win her first WTA title. She thus rose 36 ranking places to No. 66, easily beating her previous high of No. 96. With this victory she became the youngest Ukrainian winner of a WTA title.^[2]

Notes

• ¹ The first Premier 5 event of the year has switched back and forth between the Dubai Tennis Championships and the Qatar Total Open since 2009. Dubai was classified as a Premier 5 event from 2009–2011 before being succeeded by Doha for the 2012–2014 period. In 2015, Dubai regained its Premier 5 status while Doha was demoted to Premier status. The two tournaments have since alternated status every year.
