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.
STUTTGART, Germany — Matteo Berrettini beat Canadian teenager Felix Auger-Aliassime 6-4, 7-6 (11) to win the Stuttgart Open and his third tour-level title on Sunday.
The Italian saved five set points in a second-set tiebreaker and clinched his first title on grass. His other titles came at Budapest in April, and Gstaad, Switzerland, last year.
The 18-year-old Auger-Aliassime previously reached championship matches in Rio de Janeiro in February and the Lyon Open in May – both on clay.
Berrettini won all 50 of his service games during the week in Stuttgart. He did not face a break point against Auger-Aliassime.
Auger-Aliassime progressed to the final in his first professional grass tournament without playing Saturday as compatriot Milos Raonic withdrew ahead of their semifinal due to back problems.
NOTTINGHAM, England — Former champion Donna Vekic finally got to play on grass at the Nottingham Open on Friday but had to overcome multiple rain delays and another switch indoors before reaching the semifinals.
The second-seeded Vekic defeated Kristina Mladenovic 7-5, 6-4 in a match played on two surfaces as rain again played havoc with the schedule.
The opening two days were completely washed out before organizers decided to switch the first and second rounds indoors as rain fell for four consecutive days.
Vekic, who won the tournament in 2017, will play Germany’s Tatjana Maria in her third straight semifinal in Nottingham. Maria earlier defeated Ajla Tomljanovic 6-3, 7-6 (7) in the only match completed on grass so far at the tournament.
Also Friday, American Jennifer Brady defeated fourth-seeded Maria Sakkari of Greece 7-5, 6-3 to set up a semifinal against top-seeded Caroline Garcia.
Garcia rallied to beat Romanian qualifier Elena-Gabriela Ruse 4-6, 7-6, 6-1 in the last quarterfinal.
