LONDON –Alexander Zverev came from a break down in both sets to defeat Marin Cilic 7-6 (5), 7-6 (1) at the ATP Finals on Monday.
Facing each other in their opening match for a second straight year, Zverev produced the slightly steadier tennis in an error-strewn contest to extend his record against Cilic at the O2 Arena to 2-0.
The fifth-seeded Cilic broke at the first opportunity for 2-0 but then wasted break points in the German’s next two service games, before dropping his own serve when attempting to close out the set at 5-3.
Having struggled to that point, the third-seeded Zverev found some consistency to take the tiebreaker.
In the second set, once more fell he behind at 4-3.
However, Cilic, who amassed 46 unforced errors, allowed Zverev to break straight back.
Despite saving a match point at 4-5, Cilic wilted in another tiebreaker to fall to 1-9 across his four appearances at the tournament.
In the late match, top-ranked Novak Djokovic begins his campaign for a sixth ATP Finals title against American debutant John Isner.
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.
