Jessica Pegula

On August 30, 2011, Pegula was granted a wildcard into the main draw of the US Open doubles tournament, where she was paired with Taylor Townsend. They eventually lost in the third round to the third-seeded team of Vania King and Yaroslava Shvedova. In March 2012, Pegula was handed a wildcard to the qualifying draw in Indian Wells and surprised higher ranked players Bojana Jovanovski and Paula Ormaechea to qualify for the main draw where she lost to Magdaléna Rybáriková in three sets.

Pegula made her major singles debut at the US Open as a qualifier. She defeated Shuko Aoyama, Margarita Gasparyan, and Melanie Oudin to reach the main draw, where she beat Alison Van Uytvanck in the first round. In the second, Pegula was defeated by Dominika Cibulková in three sets.

In 2018, Pegula reached her first WTA singles final at the Tournoi de Québec in September as a qualifier. She beat Kristýna Plíšková, Ons Jabeur, second seed Petra Martić and fifth seed Sofia Kenin en route to the final, where she lost to eighth seed Pauline Parmentier in straight sets. This brought her ranking back inside the top 200 and helped her finish the year inside the top 125.

Pegula began the year primarily playing on the ITF Circuit, before cracking inside the top 100 in February for the first time in her career. This allowed her to enter several larger WTA Tour events, including in Indian Wells and Miami. Her best result during the early clay court season came in Charleston, where she upset world No. 12, Anastasija Sevastova, en route to the third round. This helped her break inside the top 75 for the first time. She also competed in the main draw of a Grand Slam tournament other than the US Open for the first time. She was defeated in the first round of the French Open by eventual champion Ashleigh Barty, before falling in the same stage at Wimbledon to Mihaela Buzărnescu.

Pegula achieved the best result of her career at the start of the North American hardcourt season when she won her first career singles title at the Washington Open, defeating Camila Giorgi in the final. This took her to a new career-high ranking of world No. 55. Despite failing to win another main-draw match the rest of the season, Pegula finished the year ranked inside the top 100 for the first time, at No. 76.

Pegula started her 2020 tennis season at the Auckland Open where she defeated CiCi Bellis in the first round. She followed this up with two more straight-set victories over Tamara Zidanšek and Alizé Cornet to reach the semifinals. There she beat Caroline Wozniacki in three sets to advance to her third Tour singles final. Facing off against 23-time Grand Slam singles winner Serena Williams for the first time, Pegula lost in straight sets. She then competed at the Australian Open for the first time, where she was defeated by another American, Taylor Townsend, in straight sets in the first round.

Pegula's next big triumph came at the Cincinnati Open, a Premier 5 tournament. Having already beaten two Russians to qualify for the main draw, she opened her campaign with a straight-sets win over American Jennifer Brady followed by a win over another fellow American, 2019 French Open semifinalist Amanda Anisimova. She then caused a huge upset by defeating fifth seed and world No. 11, Aryna Sabalenka, in the third round, thus advancing to her first quarterfinal at any WTA Premier level event. Her run came to an end with a straight-sets loss to 14th seed Elise Mertens.

At the US Open, Pegula recovered from a set down to record her first Grand Slam main-draw win since the 2015 US Open, defeating Marie Bouzková in a third-set tiebreak. She then beat Kirsten Flipkens to advance to the third round of a Grand Slam event for the first time, where she lost to sixth seed and former world No. 2, Petra Kvitová.

Pegula attained success at the Australian Open, defeating former Australian Open champion and 12th seed Victoria Azarenka, Kristina Mladenovic, former US Open champion Samantha Stosur and fifth seed Elina Svitolina to reach her first major quarterfinal where she lost to eventual runner-up, Jennifer Brady, despite winning the first set. This strong showing allowed Pegula to enter top 50 for the first time, and took her to a new career-high ranking of No. 43 in the world.

Later in April, she achieved another career-high of No. 32, after reaching the semifinals at the Qatar Ladies Open as a qualifier where she lost to the eventual champion, Petra Kvitová, and a fourth-round run as a seeded player at the Miami Open, losing to Maria Sakkari in a tight three-set match. Her third-round win over Karolína Plíšková in Miami was the third win in a row in three tournaments over the same player.

In May, at the Italian Open, where she participated for the first time, she recorded the biggest victory of her career over world No. 2, Naomi Osaka, in the second round. This was her fifth top-ten win in 2021. She next prevailed over Ekaterina Alexandrova to set up a quarterfinal match with Petra Martić. Thanks to this great showing at her second WTA 1000 quarterfinal in 2021, after the one at Dubai, she entered top 30 for the first time.

On her debut at the WTA Finals, Pegula lost all her matches of the group stage, winning only one set in three matches.

She then beat Harriet Dart in the first knockout stage before scoring the biggest win of her career with a straight sets victory over Iga Świątek, her first win over a current world No. 1 and first against the Pole since the 2019 Washington Open. In the finals, she beat 2022 French Open semifinalist Martina Trevisan to help the United States win the first ever United Cup title.

Coming off the heels of her win over Świątek and consistency throughout the 2022 season, Pegula was considered one of the favorites for the Australian Open title. She breezed through her first three matches with straight set wins over Jaqueline Cristian, Aliaksandra Sasnovich, and Marta Kostyuk. In the fourth round, Pegula faced off against 2021 French Open champion Barbora Krejčíková for the first time, defeating the 20th seed in straight sets to advance to her third consecutive Australian Open quarterfinal.

She repeated the feat at Miami where again she came back from a set down and won against 26th seed Potapova, saving two match points, to reach this time the semifinals, after several match postponements due to a four hours rain delay. She became the first American woman to reach back to back semifinals in Miami since Serena Williams in 2014 and 2015. In doubles at the same tournament, she won her fifth overall and third WTA 1000 team title with her partner, Coco Gauff. They became the first all-American duo to win the Miami Open doubles title in 22 years, defeating Leylah Fernandez and Taylor Townsend in the final. At the WTA 1000 Madrid Open, Pegula and Gauff reached again the final where they lost to Azarenka and Beatriz Haddad Maia. The match was followed by controversy as none of the participating players were allowed to make a speech on the podium during the awards ceremony. The organizers subsequently apologized for the mistake. At the next WTA 1000 in Rome, the pair played their third consecutive final. As a result, Pegula reached a new career-high of No. 2 in doubles.

At the WTA Finals, where she qualified for a second year in a row, she recorded her first win ever at this tournament, and her 40th singles hardcourt win over Elena Rybakina in straight sets, the most of anyone in the season. It was a fourth straight win over a top 10 player extending her personal best.

She also became the first American to claim three wins in a season against the WTA's No. 1 since Serena Williams in 2012.
