Shapovalov suffers 1st-round loss at Wimbledon, fellow Canadian Mboko upsets Frech after late entry

Victoria Mboko wasn't even supposed to be in the draw, and then she delivered a Canada Day stunner at Wimbledon.

The 18-year-old from Toronto was added to the tournament just three hours before her match after Anastasia Potapova withdrew.

She made the most of it, upsetting 25th-seeded Magdalena Frech of Poland 6-3, 6-2 in Tuesday's first round.

Frech entered the tournament ranked No. 24 in the world, while Mboko sits at No. 97.

Mboko had originally fallen short of qualifying with a three-set loss to Australia's Priscilla Hon in her final match last Thursday.

After Frech pulled even at 2-2 in the second set, Mboko reeled off four straight games, closing out the match with a backhand unforced error from Frech.

Mboko fired three aces to three double faults, won 77 per cent of her first-serve points and converted five of 10 break chances.

The rising Canadian star, who reached the third round of the French Open in May, moves on to face 23-year-old American Hailey Baptiste in the second round at London's All England Club.

Earlier, Denis Shapovalov, of Richmond Hill, Ont., was upset in the first round, falling 3-6, 6-4, 6-1, 6-4 to Argentina's Mariano Navone.

The 27th seed double-faulted 11 times and won just 53 per cent of his second-serve points.

Navone, ranked No. 41 in the world, broke Shapovalov six times in the match.

It's Shapovalov's earliest exit at Wimbledon since 2019.

Fellow Canadians Leylah Fernandez, Felix Auger-Aliassime and Gabriel Diallo remain in singles competition.

Fernandez, of Laval, Que., faces Laura Siegemund on Wednesday, while Montreal's Auger-Aliassime meets Jan-Lennard Struff, and Diallo, also of Montreal, takes on No. 5 Taylor Fritz.

Ottawa's Gabriela Dabrowski and partner Erin Routliffe of New Zealand, the No. 2 seeds in women's doubles, are set to open their Wimbledon campaign Wednesday against China's Saisai Zheng and Xinyu Wang.

Third-seeded Alexander Zverev lost to 72nd-ranked Arthur Rinderknech 7-6 (3), 6-7 (8), 6-3, 6-7 (5), 6-4 in the first round at Wimbledon on Tuesday in a match that was suspended overnight.

It was Zverev's earliest exit at a Grand Slam tournament since 2019 — also at the All England Club.

Rinderknech, a 29-year-old Frenchman, had only one other career victory at Wimbledon — that was last year.

In the buildup to the tournament, Rinderknech reached the quarterfinals at Queen's Club, where he beat Ben Shelton and Reilly Opelka.

Zverev has reached the fourth round at Wimbledon three times, including last year, but never beyond that point. He lost to Fritz in five sets a year ago.

Top-ranked Jannik Sinner got his Wimbledon campaign off to an ideal start by beating Luca Nardi 6-4, 6-3, 6-0 in an all-Italian matchup on Tuesday.

The three-time Grand Slam champion, who lost a five-set French Open final to Carlos Alcaraz, is in search of his first Wimbledon title. He was a semifinalist at the All England Club in 2023.

"First matches are never easy so I'm very happy about my performance," he said in his on-court interview. "It's a new tournament, new chances, new challenges. You have one opponent at a time."

Sinner will play Aleksandar Vukic of Australia in the second round.

In other men's results, Fritz dealt with an overnight suspension before the fifth set to finish off a 6-7 (6), 6-7 (8), 6-4, 7-6 (6), 6-4 first-round win over Giovanni Mpetshi Perricard when they resumed Tuesday.

Mpetshi Perricard hit a tournament-record 153 mph serve in the opening game.

Third-ranked Jessica Pegula thought she was done with first-round hiccups.

Then she faced Elisabetta Cocciaretto, who needed just 58 minutes to stun the American 6-2, 6-3 on Tuesday.

It was the third-seeded Pegula's earliest exit at a Grand Slam tournament in five years.

And it came days after Pegula won the the grass-court Bad Homburg Open in Germany on Saturday, beating Iga Swiatek in straight sets.

"This is definitely probably the worst result I've had all year," she said.

Pegula, a quarterfinalist at Wimbledon in 2023, hit only five winners and made 24 unforced errors.
