Kenin began playing low-level tournaments on the ITF circuit in 2013 and won her first two professional matches at the age of 14.
With her wild card from winning the USTA junior national championship, she made her Grand Slam debut at the 2015 US Open, losing her opening match to Mariana Duque-Mariño.
The following year, Kenin won her first two ITF titles, the first at a $25K event in Wesley Chapel in Florida and the second at a $50K event in Sacramento in California.
The latter title helped her win the US Open Wild Card Challenge to earn a wild card into the main draw of the US Open for the second time.
At the US Open, she lost her first round match to Karolína Plíšková, her only WTA Tour-level match of the year.

After beginning the 2017 season ranked outside the top 200, Kenin steadily rose up the WTA rankings throughout the year while playing exclusively on the professional circuit.
She progressed into the top 150 in August after a string of successful results during the summer, including winning an ITF $60K tournament at Stockton and finishing runner-up at the Lexington $60K event.
These ITF performances helped her win the US Open Wild Card Challenge for the second straight year.
At the 2017 US Open, Kenin advanced beyond the first round of a Grand Slam tournament for the first time, defeating compatriots Lauren Davis and Sachia Vickery before losing to the 2006 champion Maria Sharapova in the third round.
These were also her first two match wins on the WTA Tour.
Kenin's success at the US Open helped convince her to turn professional in September, foregoing a scholarship to attend the University of Miami.
She finished the year ranked No.
108 in the world.
