CoCo Vandeweghe

Coco's maternal grandparents are 1952 Miss America Colleen Kay Hutchins and former New York Knicks basketball player Ernie Vandeweghe.

Her uncle, her mother's brother, is basketball player Kiki VanDeWeghe, and her grandmother's brother was NBA player Mel Hutchins.

Coco first started playing tennis with her elder brother, Beau, at the age of eleven.

Tennis was the last sport she chose in her early life, after trying, among other things, basketball and wrestling.

Born to 1976 Olympic swimmer Tauna Vandeweghe and her then-husband, Robert Mullarkey.

Coco Vandeweghe (born Colleen Mullarkey; December 6, 1991) is an American former professional tennis player.

A former junior US Open champion and top 10 singles player, she won two WTA Tour titles, both at the Rosmalen Grass Court Championships.

Vandeweghe made her WTA Tour debut at the 2006 San Diego Classic at the age of 14, losing in the first round to Kateryna Bondarenko.

The following year, she played there again as a wildcard and still lost in the first round.

Vandeweghe eventually turned pro in April 2008.

Self-described as a "total California girl", she spends most of her off-season at the beach with her family.

She is good friends with fellow American players Madison Keys, Irina Falconi, and Shelby Rogers.

Vandeweghe is known to have one of the strongest serves on tour.

In 2008, she reached the singles final of the USTA Girls 18s national championship as the 3rd-seed, losing to top-seeded Gail Brodsky.

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.

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, particularly her forehand.

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 main weaknesses, although they have been steadily improved.

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 also coached her.

As a junior, Vandeweghe was coached by Guy Fritz, the father of Taylor Fritz.

In addition, Vandeweghe twice reached the quarterfinals at Wimbledon in both 2015 and 2017.

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.

She is also a two-time Grand Slam finalist in mixed doubles, reaching the final at the 2016 Australian Open with Horia Tecău and the 2016 US Open with compatriot Rajeev Ram.

In 2017, she reached two major semifinals and the final of the WTA Elite Trophy to enter the top 10, reaching her career-high singles ranking of world No. 9 in January 2018.

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 U.S. team to its first championship since 2000.

Her best surface was grass.

Vandeweghe also won one major doubles title, which she won at the 2018 US Open with partner Ashleigh Barty.

Despite being predominantly a singles player, she also exceled at doubles.

In 2018, Vandeweghe won her first Grand Slam title, partnering Ashleigh Barty 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.
