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.[9]

In 2008, Vandeweghe played in her first Premier tournament at Miami, where she lost to Sabine Lisicki in the first round. At the US Open, where she would go on to win the girls' singles title, Vandeweghe made her debut in the main draw of a Grand Slam with the wildcard she received from reaching the finals of the USTA junior national championship. She would lose to second-seeded and eventual runner-up Jelena Janković in the first round.[9]

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. The trio would win the competition, with Vandeweghe partnering with Williams to win their doubles match in the final. In March, she was granted a wildcard to play at Miami, but lost in the first round. In Vandeweghe's second WTA tournament of the year, she recorded her first WTA Tour-level win at the LA Women's Tennis Championships, defeating world No. 58, Tathiana Garbin, in the first round.

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 the Stanford Classic 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.[11][12][13] 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.

In 2013, she 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 Stanford Classic.

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.[14] 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^(7–3), 2–6, 3–6, who spoke brightly of Vandeweghe following the match. Vandeweghe also became the fourth North American woman other than the Williams sisters to make the semifinals at an Australian Open in five years, following Sloane Stephens (2013), Bouchard (2014), and Madison Keys (2015). Following the tournament, Vandeweghe rose into the top 20 for the first time in her career. Seeded 19th at the French Open, she lost in the first round to Magdaléna Rybáriková.

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.

At the Australian Open, Vandeweghe was eliminated in the first round by the Hungarian Timea Babos. During the match, she was warned for delaying the start of the second set while she demanded that a banana be delivered to the court. Towards the end of the match, she was penalized a point for shouting expletives at her opponent. She was later fined $10,000.[15][16] The incident generated controversy in the press and on social media with tennis fans calling Vandeweghe's actions on the court "disgusting."[17] Vandeweghe's on-court behavior has been criticized in the past.[18][19]

Shortly after, Vandeweghe revealed that she had suffered from a severe virus during the Australian Open and was ordered by her doctor to limit her travel, due to recovery.

An early defeat in Nottingham to Petra Martic followed. At Wimbledon, Vandeweghe was defeated by Katerina Siniakova in three sets, but worse was that she injured her right ankle during the match. The injury meant that Vandeweghe and Barty had to withdraw from the doubles competition, and she was sidelined during the US Open Series.

Vandeweghe made her comeback at the Western & Southern in Cincinnati and had another defeat. To get more matches before the US Open, Vandeweghe received a wildcard for the Connecticut Open. She met Rybariková in the first round and was forced to retire from the match in the third set with pain in her injured ankle.
