CoCo Vandeweghe

At the beginning of 2019, Vandeweghe was forced to withdraw from several tournaments, including the Australian Open, due to injury. Shortly after, she published a video on her social profile accounts how serious her ankle injury was. The ankle injury had plagued her since Wimbledon 2018 and kept her out through the early hardcourt season, as well as the entire clay and grass court seasons, including the French Open and Wimbledon.

Vandeweghe made her first Final of 2019 in September at the Central Coast Pro Tennis Open, which is an ITF $60,000 level event. She fell to fellow American Shelby Rogers 4–6, 6–2, 6–3. In November, she made the Final at the Houston Oracle Challenger Series, a WTA 125K Series event. This final was Vandeweghe's biggest since her return from injury. She fell to Kirsten Flipkens 6–7, 4–6.

Vandeweghe made her return in the end of July at the Silicon Valley Classic in San Jose, where she was awarded a wild card. At this point, her singles ranking had dropped to 636 in the world, having not played a tournament in ten months. She defeated the young Czech Marie Bouzková in the first round to record her first match win since June 2018. Vandeweghe revealed after her comeback match that her ankle problem was diagnosed as Complex Regional Pain Syndrome, a nervous disease in the system who occur after a injury. Vandeweghe also added what she went through after the nerves had calmed down. She was defeated by second seed and world No. 10 Aryna Sabalenka in the second round. In August, she reached the doubles Semifinals at the Western & Southern Open with Bethanie Mattek-Sands.

Vandeweghe's prowess at both singles and doubles helped her win all eight of her Fed Cup rubbers in 2017 across three different ties to lead the US team to its first Fed Cup championship since 2000.

Vandeweghe traveled to Brisbane, where she represented the US at Fed Cup. Her decisive win over Samantha Stosur meant that the US team would return to World Group stages in 2017. After Fed Cup, Vandeweghe lost in the first rounds of Madrid and Rome. At the French Open, she won her first clay-court match of the season, beating Naomi Broady in three sets. In her round two match, she faced Irina-Camelia Begu, where she lost in 3 hours and 37 minutes despite serving for the match. In mixed doubles, Vandeweghe paired up with Bob Bryan. They reached the quarterfinals, where they lost to French duo Kristina Mladenovic and Pierre-Hugues Herbert.

Vandeweghe represented the United States at the 2017 Hopman Cup and Fed Cup. She won all eight matches she played in the Fed Cup as the US team won the tournament.

Despite being predominantly a singles player, she also excels at doubles. In 2016, she partnered with Martina Hingis in much of the second half of the season and reached the semifinals of the US Open, a performance that lifted her to a then-career-high ranking of No. 18 in the world. In that year, she also reached two Grand Slam mixed doubles finals at the Australian Open and the US Open. In 2018, Vandeweghe won her first Grand Slam title, and, partnering Ashleigh Barty, she won the women's doubles title at the US Open. Later on, they reached the semifinals at the 2018 WTA Finals, lifting Vandeweghe to a new career-high ranking of No. 14.

Vandeweghe got off to a rough start in 2016. She commenced her season at the ASB Classic, where she was the seventh seed but lost to her compatriot and good friend Irina Falconi in the first round 7–5, 4–6, 3–6, despite being up a break in the final set. An alternate for Sydney, Vandeweghe lost in the first round to Jelena Jankovic 3–6, 4–6. She then traveled to Melbourne to compete at the 2016 Australian Open, where she drew her countrywoman Madison Brengle in the first round, again losing 3–6, 4–6. However, Vandeweghe enjoyed some success in women's doubles, where she and her partner, Anna-Lena Grönefeld, reached the quarterfinals and losing to world number ones Sania Mirza and Martina Hingis in three sets. Vandeweghe teamed up with Romania's Horia Tecău in the mixed doubles event where they made the final, falling just short to Elena Vesnina and Bruno Soares.

After the Australian Open, Vandeweghe participated at Dubai Duty-Free Tennis Championships, where she scored her first win of 2016, knocking out the sixth seed Karolína Plíšková. She went on to reach the quarterfinals of Dubai, with another strong win over Kristina Mladenovic, before losing to Elina Svitolina in three sets. At the Qatar Total Open, Vandeweghe made it to the third round, with straight-set wins over Kirsten Flipkens and Belinda Bencic, obtaining her first top-ten victory of 2016.

In March, Vandeweghe made the third round at Indian Wells, beating Kiki Bertens and Svetlana Kuznetsova before losing to Jelena Jankovic for the second time in 2016. In doubles, Vandeweghe teamed up with fellow American Bethanie Mattek-Sands, where they unprecedentedly claimed the doubles title. En route to the title, they beat Dabrowski/Martínez Sánchez, the second seeds Chan/Chan, the eighth seeds Spears/Atawo, the third seeds Babos/Shvedova in the semifinals, and Görges/Plíšková in the final. It was Vandeweghe's first doubles title. After Indian Wells, Vandeweghe participated at the Miami Open, where she also reached the third round after defeating Samantha Crawford and world No. 6 Carla Suárez Navarro before losing to Monica Niculescu in straight sets.

She then played at the Aegon Classic, where she beat world No. 3 and top seed Agnieszka Radwańska, Christina McHale and Yanina Wickmayer, before losing to Barbora Strýcová and thus ending her eight-match winning streak. After this tournament, her ranking rose to a career-high of No. 30. At the Wimbledon Championships, Vandeweghe was seeded at a Grand Slam tournament for the first time as No. 27. She made the second week for the second straight year. She beat Bondarenko, Babos, and sixth-seeded Vinci before losing to eventual quarterfinalist and 21st seed Anastasia Pavlyuchenkova in the fourth round. Her win over Vinci was her fourth top-ten victory in 2016.

Vandeweghe struggled for the remainder of the 2016 season, registering just two more wins; over Nicole Gibbs in Stanford at the Bank of the West Classic, where she was the fourth seed, and over Sara Errani in Cincinnati.

Vandeweghe has played in the World TeamTennis pro league for seven seasons. She was a wildcard player for the Philadelphia Freedoms in 2016, after appearing as a roster player for them in 2015.

In 2015, just three days before the French Open, Vandeweghe and coach Maciej Synowka parted ways, having worked with each other for over a year. Vandeweghe is now coached by Craig Kardon, who has previously worked with star players like Martina Navratilova, Lindsay Davenport, Jennifer Capriati, and Ana Ivanovic.

Seeded 20th at the US Open, Vandeweghe recovered from a set down to beat compatriot Alison Riske in the first round then conquered Ons Jabeur for her first victory on Arthur Ashe stadium and to advance to the third round of the US Open for the first time in her career. She then defeated tenth seed Agnieszka Radwanska in three tight sets followed by a victory over 2015 French Open finalist Lucie Safarova to reach her third Grand Slam quarterfinal of the year, where she stunned top seed and world No. 1, Karolina Pliskova in straight sets to advance to her second major semifinal, where Keys defeated her, thus being denied of the chance to reach her first Grand Slam final. Following the tournament, Vandeweghe rose to a career-high ranking of No. 16. She concluded the season by reaching the final of the Elite Trophy in Zhuhai. This result helped her break into the top 10 for the first time, ending the season as No. 10.

Vandeweghe is known to have one of the strongest serves on tour. In 2014, she hit 306 aces, third-highest on tour. She plays very aggressively, and likes to take the ball early and on the rise on both sides. Her groundstrokes are heavy and are delivered flat and powerful. Vandeweghe is efficient at the net and enjoys moving forward to avoid extended rallies. Because of her consistent serve, she has a solid mental game. Overall fitness and movement are cited as her weaknesses. Her favorite shot is her forehand down the line, and her preferred surfaces are hard and grass courts. Previously, she was coached by Robert Van't Hof in Newport Beach, California, and Adam Peterson on the road. Pat Cash currently coaches her.

Vandeweghe commenced her 2014 season at the ASB Classic, where she was the top seed in the qualifying rounds. She beat Valeria Solovyeva and Irena Pavlovic in straight sets before losing to Kristýna Plíšková in three sets.

In 2013, Vandeweghe began the season with another slow start. When her ranking fell outside the top 200, she began to rebound by reaching the quarterfinals at the Bank of the West Classic. Later in the season, Vandeweghe was able to qualify for the US Open and beat another qualifier in the first round to lift her ranking back closer to the top 100.

Vandeweghe found form in the grass-court season. She won her second WTA title at the Ricoh Open.

At the Australian Open, Vandeweghe easily defeated 15th seed Roberta Vinci in the first round 6–1, 7–6. After cruising through her match against Pauline Parmentier, Vandeweghe battled to defeat the 2014 Wimbledon finalist Eugenie Bouchard in three tight sets. In the fourth round, she pulled off the biggest upset of the tournament as she defeated defending champion and world No. 1 Angelique Kerber in straight sets. This victory, her first against a No. 1 player, advanced Vandeweghe to her first quarterfinal at the Australian Open and only her second quarterfinal at a Grand Slam tournament, the first being at Wimbledon in 2015. She then defeated seventh seed Garbine Muguruza in straight sets to advance to her first-ever semifinal of a Grand Slam, where she went head-to-head with the 2003 finalist Venus Williams. Despite winning the first set in a tiebreak and delivering a brilliant performance, Vandeweghe was defeated by Williams 7–6, 2–6, 3–6, who spoke brightly of Vandeweghe following the match.

In the final, they defeated second-seeded Timea Babos and Kristina Mladenovic 3–6, 7–6, 7–6. Vandeweghe and Barty held three championship points in the third set before they converted it on a double fault from the serve of Mladenovic.

Vandeweghe got off to a slow start in the 2012 season but started to gain some momentum in the grass-court season when she reached the final of the $75K event at Nottingham. She followed this up by qualifying for Wimbledon, but she ended up losing the first round. At her next tournament, Vandeweghe entered the main draw of Bank of the West Classic at Stanford as a lucky loser and made it to her first career WTA final. In the semifinal, she upset fifth-seeded Yanina Wickmayer before falling to top-seeded Serena Williams in straight sets. She was the first lucky loser to reach a final since Melinda Czink in early 2005 and also rose to a then career-high ranking of No. 69 in the world. Vandeweghe's best result in the rest of the year was a quarterfinal at the Citi Open.

Her next event was the Bank of the West Classic in Stanford, where she made the final in 2012 as a lucky loser. She made the second round with a comfortable win against fellow American Kristie Ahn before losing to third seed Angelique Kerber.

Towards the end of the season, Vandeweghe won first career match in the main draw of a Grand Slam tournament at the US Open, defeating world No. 56 Alberta Brianti in the first round.

In 2010, Vandeweghe received a wildcard to the Australian Open, but she lost in the first round. In the spring, Vandeweghe won two back-to-back ITF tournaments at Carson and El Paso to see her WTA ranking climb from outside the top 300 to inside the top 200.

In 2009, Vandeweghe obtained an invitation from the Hong Kong Tennis Patrons' Association to play the JB Group Classic exhibition tournament with compatriot Venus Williams and Argentine Gisela Dulko in January.

Vandeweghe also won the doubles event with Jamie Hampton, defeating the top-seeded pair of Brodsky and Mallory Cecil in the final. With these results, she earned wildcards into the main draws of the singles and doubles events at the US Open.

In general, Vandeweghe did not play many junior events and needed a wildcard to enter the 2008 US Open girls' singles tournament. Nonetheless, she would go on to win the championship without dropping a set. Vandeweghe moved up to the ITF circuit after the event, and this would end up being her last junior tournament. With the victory, she rose to a career-best junior ranking of No. 15 in the world.
