Sloane Stephens' comeback from injury will keep going all the way to the U.S. Open semifinals.
Stephens edged No. 16 seed Anastasija Sevastova of Latvia 6-3, 3-6, 7-6 (4) this morning to reach the final four of a major tournament for the first time since 2013.
Sidelined from tennis for nearly a year and unsure what she could accomplish just last month, the unseeded American advanced to face the winner of the match between Grand Slam champions Venus Williams and Petra Kvitova later this morning.
The 2016 ASB Classic Champion had left foot surgery in January and didn't return to the tour until Wimbledon until June. Her ranking fell to 934th before she reached consecutive semifinals at hard-court tournaments in Toronto and Cincinnati in August.
"When I started my comeback at Wimbledon, I could have never even dreamed of something like this happening, having these results," Stephens said in an interview on the court after the match.
She's No. 83 now with 13 wins in her last 15 matches, becoming just the seventh player outside the top 50 to reach the U.S. Open women's semifinals since the rankings began in 1975.
Her only previous Grand Slam semi was at the Australian Open four years ago.
Sevastova beat Maria Sharapova in the fourth round and was trying to reach the first major semifinal of her career. She received treatment from a trainer late in the first set for a problem with her upper right leg.
