Next on was US Open champion Sloane Stephens against Belarus’ No. 1 Aryna Sabalenka. The young Belarusian came out firing to a 3-0 lead, as Stephens struggled to settle down, playing with tape on her left knee. Boosted by Stephens' shakiness, Sabalenka kept connecting on all the right shots to seal the opening set, 6-3.
While Vandeweghe came into the Fed Cup on a hot streak after reaching the Zhuhai final, world No. 13 Stephens hasn't won a match since the US Open. Sabalenka reached her first WTA final recently in Tianjin (losing to Maria Sharapova), rising to a career-high of No. 76 in October.
Stephens settled in, as the teenager lost her rhythm, with the moment seemingly overwhelming her. The American cruised to a 6-3 set to push the match into a decider. Both women were dealing with nerves in the third set, but it was the 19-year-old local hero that edged ahead 5-4. Stephens would save three match points before Sabalenka broke to secure the biggest win of her career, 6-3, 3-6, 6-4.
