SAN ANTONIO — Sloane Stephens beat Timea Bacsinzsky after Viktorija Golubic upset Madison Keys in straight sets Saturday, leaving the United States and Switzerland tied 1-1 in their Fed Cup World Group playoff.
Stephens, the No. 8 player in the world, won 6-4, 6-3 on the hard court inside Freeman Coliseum. Her win for the Americans was crucial after the 80th-ranked Golubic was in control throughout in a 6-2, 6-3 victory over the No. 14 Keys.
Stephens is scheduled to play Golubic on Sunday, followed by Keys against Bacsinzsky. If necessary, Sophia Kenin and Jessica Pegula of the United States would play Ylena In-Albon and Conny Perrin in doubles.
The winning team moves to the 2020 World Group draw. The losing team is relegated to World Group II next season.
Stephens came back from deficits of 3-1 in the first set and 2-0 in the second against Bacsinzsky.
Stephens broke Bacsinzky in the seventh game of the second set to take the lead, and Bacsinzky became error prone after she was called for a questionable double hit in the eighth game.
In the first match, Keys made 47 unforced errors and was 0 for 4 on break points against the soft serving Golubic.
Golubic broke Keys twice in the first set and never let her wrest the momentum after dropping the first game of the second. With the score 3-3, Golubic rallied from down 40-15 in the seventh game to break Keys, who dropped to 4-5 in Fed Cup singles matches.
The Americans have won all eight meetings against Switzerland in Fed Cup play.
DALLAS – Marcos Giron advanced to the second round of the Dallas Open with a 6-4, 6-7 (1), 6-1 victory over Alex Rybakov on Tuesday.
The seventh-seeded Giron, who reached the semifinals of the inaugural event a year ago, responded quickly after failing to close out the second set, winning the first five games of the deciding set.
Rybakov broke his fellow American when Giron was serving for the match in the second set. Then Rybakov won the first six points of the second-set tiebreaker.
“I’m really happy with how I was able to reset in the third and just get back to the game plan from the beginning and elevate,” Giron said. “He played well and served well and kind of hung in there.”
Eighth-seeded Adrian Mannarino of France won the final five points of a first-set tiebreaker and the last four games of the second to beat American Steve Johnson 7-6 (6), 6-2.
J.J. Wolf, the No. 6 seed, had little trouble in a 6-3, 6-3 victory over fellow American Brandon Holt.
John Isner, the fifth seed and unofficial tournament host in his hometown event, played later Tuesday. Like Giron, Isner lost in the semifinals last year.
DALLAS – Wild-card entry Jack Sock opened with a 7-6 (2), 4-6, 6-4 victory over Ilya Ivashka at the Dallas Open, setting up a second-round meeting with top-seeded fellow American Taylor Fritz.
Sock broke Ivashka’s serve in the final game to win the match. Ivashka fell behind 2-0 to start the final set but broke Sock to get back on serve.
Down a break early in the second set, Ivashka rallied to force the deciding set after Sock cruised in the first-set tiebreaker.
The eighth-ranked Fritz is back for the second Dallas Open after losing in the semifinals as the top seed in the inaugural edition of the indoor hard-court event last year. Defending champion Reilly Opelka isn’t in the field.
