This loss would cause Kerber to fall outside the top ten in the WTA rankings for the first time since 2015. Sloane Stephens won her first Grand Slam title, defeating Madison Keys in the final, 6 -- 3, 6 -- 0. It was the first all - American women 's final at the US Open since 2002, and the second time in three years that the final featured two first - time Grand Slam singles finalists from the same country. Stephens became the second unseeded woman in the Open era to win the US Open after Kim Clijsters in 2009. For the first time since 1981 at the US Open -- and at any Grand Slam event since the 1985 Wimbledon Championships -- all four semifinalists were American. Both occasions were also the last time that four players from the same country accomplished these feats. In addition, Kaia Kanepi became the first qualifier to reach the US Open quarterfinals since Barbara Gerken, also in 1981. This was Maria Sharapova 's first Grand Slam appearance since the 2016 Australian Open, following a suspension for violating the anti-doping rules. Sharapova was awarded a wildcard into the main draw and advanced to the fourth round, where she lost to Anastasija Sevastova. Garbiñe Muguruza became the new WTA No. 1 player at the end of the tournament despite losing in the fourth round, after Karolína Plíšková ( who held the top ranking at the start of the tournament ) failed to defend her finalist points from 2016. Eight of the top nine seeds ( with the exception of Kerber ) were in contention for the no. 1 ranking at the start of the tournament.
