MIAMI GARDENS, Fla. — Indian Wells champion Bianca Andreescu retired from her fourth-round match at the Miami Open while trailing Anett Kontaveit 6-1, 2-0 Monday.
Andreescu called a medical timeout after the first set to receive treatment on her right shoulder. She received similar treatment during her third-round victory over Angelique Kerber, who afterward told Andreescu she was the “biggest drama queen ever.”
Andreescu, an 18-year-old Canadian, defeated Kerber in the Indian Wells final on March 17 for her first career title.
The No. 21-seeded Kontaveit was joined in the Miami quarterfinals by Petra Kvitova, who faced only one break point and beat Caroline Garcia 6-3, 6-3.
Kvitova, a two-time Wimbledon champion, is ranked a career-high No. 2 and will rise to No. 1 if she wins the title. No. 1 Naomi Osaka lost in the third round.
Kvitova’s match was halted because of rain for nearly two hours, and she took advantage.
“I had a quick nap, which was really helpful,” she said.
No. 12-seeded Ashleigh Barty also advanced by beating No. 7 Kiki Bertens 4-6, 6-3, 6-2.
In men’s play, No. 6 Kevin Anderson hit 13 aces and advanced to the fourth round by beating Joao Sousa 6-4, 7-6 (6).
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.
