MIAMI GARDENS, Fla. – Former U.S. Open champions Emma Raducanu and Sloane Stephens were knocked out of the Miami Open hours after No. 1-ranked and defending champion Iga Swiatek pulled out of the tournament because of a rib injury.

Bianca Andreescu – the 2019 U.S. Open champ – defeated Raducanu 6-3, 3-6, 6-2. Andreescu improved to 2-0 lifetime against Raducanu, the 2021 winner at Flushing Meadows.

“Miami has a special place in my heart,” Andreescu said. “I’ve been coming here since I was I think 12 years old, whether it’s for vacation or training or, yeah, Orange Bowl. I love that tournament very much. Yeah, coming back here, I think it’s just good vibes overall.”

Andreescu moves on to face 10th-ranked Maria Sakkari, who had a first-round bye.

Shelby Rogers beat Stephens 6-4, 3-6, 6-2. Stephens has six hard-court titles, including the U.S. Open in 2017 and Miami in 2018.

Rogers will face Australian Open champion and world No. 2 Aryna Sabalenka, who beat Rogers in the second round at Melbourne Park. Sabalenka is coming off a loss in the final at Indian Wells, California, last week.

On the men’s side, Dusan Lajovic beat three-time Grand Slam champion Andy Murray 6-4, 7-5.

“I served pretty well, but the rest of the game was a bit of a problem today,” the 35-year-old Murray said. “Made a number of errors that obviously I wouldn’t expect to be making. I didn’t really feel like I moved particularly well, which is really important for me.”

Lajovic, a 32-year-old Serbian, will face Maxime Cressy, who had a first-round bye.

Swiatek withdrew because of a rib injury that she is hoping will heal during a break from competition. The 21-year-old from Poland also will sit out her country’s Billie Jean King Cup qualifier matches against Kazakhstan on April 13-14.

“I wanted to wait ’til the last minute” to decide whether to play in Miami, Swiatek said at a news conference at the site of the hard-court tournament that began Tuesday. “We were kind of checking if this is the kind of injury you can still play with or this is kind when you can get things worse. So I think the smart move for me is to pull out of this tournament because I want to rest and take care of it properly.”

In other action, 24-year-old American J.J. Wolf defeated Alexander Bublik 7-5, 6-3. He’ll face No. 7-ranked Andrey Rublev, who had a first-round bye.

Gael Monfils retired from his match against Ugo Humbert due to a persistent wrist injury.

MIAMI GARDENS, Fla. – Camila Giorgi hit 14 double-faults, blew a 5-0 lead in the final set and needed four match points before finally pulling out a 7-6 (4), 6-7 (4), 7-6 (4) victory against Kaia Kanepi in the first round of the Miami Open.

The match lasted 3 hours, 32 minutes, tying for the longest on the WTA Tour this season. The players combined for 30 aces – 19 by Kanepi, who also had seven double-faults.

In the third set, Kanepi was not moving well, and Giorgi raced to a big edge. But after dropping just two of her initial 15 service games, the Italian got broken twice in a row while serving for the victory at 5-1 and 5-3 in the third set.

Kanepi saved one match point at 5-3, another at 5-4 and another in the concluding tiebreaker. Giorgi finally ended things on her next chance with a cross-court forehand winner. She’ll next face 14th-seeded Victoria Azarenka, a three-time champion in Miami and two-time winner at the Australian Open.

All seeded players at the hard-court tournament received first-round byes. Women’s matches in the main draw began Tuesday; the men start Wednesday.

It was a rough afternoon for the Czech teenage sisters Brenda and Linda Fruhvirtova. First Brenda, who turns 16 on April 2, lost the initial nine games of a 6-0, 7-5 loss to Wang Xiyu. And then Linda, 17, exited with a 6-2, 4-6, 6-4 loss against qualifier Katherine Sebov, who now meets No. 3 Jessica Pegula.

In other action, Rebecca Marino eliminated Yulia Putintseva 7-6 (4), 6-2 to set up a second-round match against 2022 French Open runner-up Coco Gauff; Irina-Camelia Begu trailed 2-0 in the first set and then 5-1 in the second before coming back in both to beat wild-card entry Alexandra Eala 6-2, 7-5; and Marta Kostyuk was a 6-3, 6-2 winner against Elisabetta Cocciaretto.

Claire Liu, an American who is ranked 59th, advanced to a second-round meeting against defending champion and No. 1-ranked Iga Swiatek when Katerina Siniakova stopped playing in the second set Tuesday because of an injured wrist.
