CHARLESTON, S.C. — Madison Keys rallied late to down top-seeded Sloane Stephens for the first time in four career meetings to reach the Volvo Car Open semifinals on Friday.
Keys pulled away from her American countrywoman to win 7-6 (6), 4-6, 6-2. Keys, seeded eighth and ranked 18th in the world, will take on Monica Puig of Puerto Rico for a spot in Sunday’s finals. The unseeded Puig defeated her third consecutive seeded opponent, topping No. 11 Danielle Collins of the United States 6-3, 6-2.
Stephens had not lost a set in three previous matches against her good friend, including in the 2017 U.S. Open finals and last year’s French Open semifinals before dropping the opening set tiebreaker. Keys dug in once again down the stretch after Stephens won the second set.
No. 5 seed Caroline Wozniacki of Denmark, the 2011 Volvo champion, also made the final four after defeating 15th-seeded Maria Sakkari of Greece 6-2, 6-2. Wozniacki will face No. 16 seed Petra Martic of Croatia, who ousted ninth-seeded Belinda Bencic of Switzerland 6-3, 6-4.
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.
