2011 US Open when she was 15 years old and reached the third round with her compatriot
Jessica Pegula. She also received a wildcard into the singles qualifying draw and defeated world No. 122,
Arantxa Parra Santonja, in the first round. The following year, Townsend requested another wildcard into the
US Open and was declined because of the USTA's concerns about her fitness. The USTA received
widespread criticism for this decision. where Townsend made her major singles debut ranked No. 205. She defeated fellow American No. 65,
Vania King, and upset the top-ranked French woman, world No. 21
Alizé Cornet, to advance to the third round, in which she lost to No. 15,
Carla Suárez Navarro.
Sloane Stephens was the only other American woman to make it that far in the tournament. Townsend also received wildcards to make her main-draw debuts at the last two major events of the year,
Wimbledon and the
US Open, but lost in the first round at each tournament. The latter loss was to
Serena Williams, who went on to win the title.
2015: Top 100 debut, and decline Townsend broke into the top 100 at the very start of the season, after reaching the second round at the

Caroline Wozniacki in the first round. In February, she made her
Fed Cup debut against

2016: Doubles dominance on the ITF Circuit With a lower ranking, Townsend returned to playing ITF events almost exclusively. Her decision to switch back to her childhood coach, Donald Young sr. after the 2015 French Open eventually began to pay off as she regained her form in the spring. In April, she repeated her feat from 2014 of winning both the singles and doubles titles at the

Miami Open as a qualifier, her best result at a
Premier tier tournament to date. In the spring, Townsend had a quieter clay-court season compared to the previous year, but still won a match at the
French Open yet again. She produced another solid performance at a premier tournament in August, making it to the second round at the
2017 Cincinnati Open, after needing to qualify for the main draw. Towards the end of the season, she won both the singles and doubles events at back-to-back tournaments for the second time in her career, this time at the $25k level. In her final tournament of the year, Townsend played in the
