Sloane Stephens Bio
Sloane Stephens is an American professional tennis player born on March 20, 1993, in Plantation, Florida. She has reached a career-high singles ranking of world No. 3 and has won eight WTA singles titles, including the 2017 US Open. Known for her athleticism and all-court game, she earned the WTA Comeback Player of the Year award in 2017. She resides in Fort Lauderdale, Florida, and is married to United States men’s national soccer team player Jozy Altidore.
Early Life and Background
Sloane Stephens was born to Sybil Smith and John Stephens, both accomplished athletes. Her mother, Sybil Smith, was the first African-American woman to be named a first-team All-American swimmer in Division I history and is enshrined in the Boston University Athletic Hall of Fame. Her biological father, John Stephens, was a Pro Bowl running back for the New England Patriots. Following her parents’ separation, Stephens was raised by her mother and her stepfather, Sheldon Farrell, who married Smith in 1997. After her stepfather passed away from cancer in 2007, and her biological father died in a car crash in 2009, she leaned on her mother and her maternal family for support.
Stephens moved to her mother’s hometown of Fresno, California, at the age of two and first picked up a racket at the Sierra Sport and Racquet Club at age nine. Former top 100 player Francisco González recognized her talent and recommended that she pursue elite training. At 11, she relocated to Boca Raton, Florida, where she trained at the Evert Tennis Academy for a year before moving to the Nick Saviano High Performance Tennis Academy, where she also began online homeschooling. She continued splitting time between California and Florida throughout her development years.
Path to Professional Tennis
Stephens began competing on the ITF Junior Circuit in 2006 and quickly rose through the ranks. By 2009, she had captured two notable junior titles, including a Grade A event, and reached a career-high junior ranking of world No. 5. In 2010, partnering with Tímea Babos, she won the girls’ doubles titles at three Grand Slam tournaments, becoming only the second pair to achieve that feat in a single season. That same year, she turned professional, made her WTA Tour main-draw debut at the Indian Wells Open, and was named the youngest player in the top 50 at year-end by the time she was 18 years old.
Her early professional years were marked by steady improvement under coach Roger Smith, who helped her crack the WTA top 100. She later worked with David Nainkin, Paul Annacone, and briefly Thomas Högstedt, before returning to longtime junior coach Nick Saviano in 2015. Her career trajectory changed dramatically when she hired Kamau Murray in late 2015. Under Murray, she transformed into one of the best players in women’s tennis, capturing her first major at the 2017 US Open and reaching a career-high ranking of world No. 3 in 2018.
Sloane Stephens Career
Early Career (2007–2011)
Stephens made her professional debut in late 2007 on the ITF Women’s Circuit and earned her first WTA Tour main-draw appearance at the 2010 Indian Wells Open just before turning 17. After posting a year-end ranking of No. 198 in 2010, she climbed the rankings with consistent results on clay and hardcourts. Her first WTA Tour quarterfinal came at the 2011 Southern California Open, and her first Grand Slam main-draw win in singles came at the 2011 US Open, where she advanced to the third round and entered the WTA top 100.
In 2012, she reached her first tour semifinal at Strasbourg, advanced to the fourth round at the French Open, and posted a third-round showing on her Wimbledon main-draw debut. She finished that season as the youngest player in the top 50 at world No. 38, establishing herself as one of the most promising young Americans on tour.
WTA Tour Breakthrough (2013)
Stephens announced her arrival on the global stage at the 2013 Australian Open, where, as a 19-year-old, she upset world No. 3 Serena Williams in the semifinals to reach her first Grand Slam singles semifinal. The victory was the first top-ten win of her career and earned her international recognition. She continued her strong form at the French Open, reaching the fourth round, and at Wimbledon, where she advanced to the quarterfinals before falling to eventual champion Marion Bartoli. She finished 2013 at world No. 12, the second-highest-ranked American, and was one of only three players to reach the second week of all four Grand Slam tournaments that year.
US Open Title and Comeback (2015–2017)
After inconsistent results in 2014 and a coaching change, Stephens won her first WTA singles title at the 2015 Washington Open without dropping a set, vaulting her back into the top 30. In 2016, she won three titles under new coach Kamau Murray, including the Auckland Open, the Mexican Open, and the Charleston Open. Her momentum was halted by a stress fracture in her left foot, which required surgery and kept her sidelined for eleven months.
Stephens returned in July 2017 with a ranking of No. 957. Within weeks, she surged back into the top 100 and capped her comeback by winning the 2017 US Open as the world No. 83, defeating close friend Madison Keys in the final. She became the lowest-ranked US Open champion in history and the first American woman other than a Williams sister to win a major since Jennifer Capriati in 2002. She was later named WTA Comeback Player of the Year and helped the United States win the 2017 Fed Cup title.
Career Peak (2018)
Stephens opened 2018 by winning the Miami Open, her first Premier Mandatory title, defeating three top-ten players en route to the championship. She then advanced to her second Grand Slam final at the French Open, where she pushed world No. 1 Simona Halep to three sets. Reaching a career-high ranking of world No. 3, she qualified for her first WTA Finals and finished as runner-up in Singapore. She ended the season ranked world No. 6, her best year-end ranking to date.
Driving Style and Strengths
Stephens is widely regarded as an all-court player whose strongest results have come on hard courts. Her game is built on elite athleticism, court coverage, and the ability to turn defense into offense with powerful counter-punching. She has been praised for her “easy power,” capable of hitting first serves above 110 miles per hour and producing flat, stinging forehand winners. While her forehand is her preferred weapon, she employs a more compact two-handed backhand and varies her patterns to disrupt opponents’ rhythm.
Notable Events and Milestones
Her 2017 US Open title stands as the defining moment of her career, highlighted by straight-sets wins over Venus Williams in the semifinals and Madison Keys in the final. She also reached the 2018 French Open final and the 2018 WTA Finals championship match. In 2024, she captured her eighth career WTA singles title at the Rouen Open, and in December 2025, she received a wildcard into the 2026 ASB Classic as she worked her way back from a period outside the top 100.

Sloane Stephens Family
Family Background and Tennis Lineage
Sloane Stephens comes from a deeply athletic family. Her mother, Sybil Smith, was a pioneer in collegiate swimming, and her late biological father, John Stephens, starred in the NFL. She also has a younger half-brother, John Stephens Jr., who plays tight end in the NFL, and another half-brother, Shawn Farrell, who played multiple sports at Notre Dame High School. Through her maternal grandfather Noel Smith, who emigrated from Trinidad to the United States to practice medicine, Stephens is of Trinidadian descent.
Personal Life
Stephens married United States men’s national soccer team player Jozy Altidore on January 1, 2022. The two had been childhood friends in Florida before reconnecting later in life. She has been active in charitable work through the Sloane Stephens Foundation, which builds tennis courts and runs after-school tennis and tutoring programs for underserved youth in Compton, Fresno, and Fort Lauderdale. She earned a bachelor’s degree in communications studies from Indiana University East in 2017 and later completed an MBA at DeVry University in 2020. She is also pursuing a Doctor of Business Administration at Keiser University.
2025 Season Performance
The 2025 season was a difficult stretch for Sloane Stephens. After a first-round loss to defending champion Aryna Sabalenka at the Australian Open, she did not appear on the WTA Tour between February and September. Her ranking fell outside the top 100, a position she had not occupied in several years. When she returned to competition at the 2025 Guadalajara Open Akron, she was eliminated in the opening round by Italy’s Lucrezia Stefanini in a match that stretched over two days.
Despite the challenges, Stephens remained focused on rebuilding her form. In December 2025, she received a wildcard into the 2026 ASB Classic in Auckland, signaling her intent to return to regular competition. The early 2026 schedule, including a return to the Australian hardcourt swing, is expected to provide her with opportunities to climb back up the rankings.
Heading into 2026, Stephens continues to work on her game and fitness. With the help of a wildcard in Auckland, she is aiming to steadily improve her ranking and rediscover the form that once took her to world No. 3. Her focus remains on consistency and rebuilding momentum, with the goal of competing in the latter stages of WTA events throughout the year.
