Mboko reaches Miami quarters

Victoria Mboko’s rapid rise has the Canadian teenager poised for Grand Slam success, former U.S. Open champion Andy Roddick said after she beat fellow teenager Mirra Andreeva 7-6(4) 4-6 6-0 ‌on Monday to reach the Miami Open quarter-finals.
Mboko picked up her first WTA Tour-level win in Miami last year and has enjoyed a string of deep runs at tournaments in 2026 highlighted by a fourth-round appearance at the Australian Open in January.
“Mboko is going to win ⁠a slam in the next two years,” Roddick said on his Served with Andy Roddick podcast.
“She’s making the quarters or better in every single event. She gets through tough three-set matches all the time,” he added.
Mboko’s losses at the Australian Open and in the Indian Wells quarter-finals both came against world number one Aryna Sabalenka, but Roddick said those defeats did little to dent his assessment of her potential.
“She plays well every single week. Losing to ‌Sabalenka, ⁠that doesn’t bother me at all. She’s physically strong and can withstand the stress test of big tennis,” he said.
“I’m just more and more impressed with her.”
Seeded 10th in Miami, Mboko turned in another assured display against doubles partner and emerging rival ⁠Andreeva on the sun-drenched hard courts, overcoming a second-set lapse to pull away in dominant fashion.
The Canadian Open champion broke the hard-serving Russian – who received treatment on her ⁠back during the match – three times in the decider and sealed victory with a blistering inside-out forehand on match point for her fifth top-10 ⁠win of the season.
Mboko will face Karolina Muchova for a place in the semi-finals after the in-form Czech crushed Alexandra Eala 6-0 6-2 earlier on Monday.

Swiatek splits with coach Fissette

World number three Iga Swiatek has ended her coaching partnership with Wim Fissette, she said on Monday, following a disappointing ‌start to the season that culminated in a shock early exit at the Miami Open.
The 24-year-old, who hired the Belgian in October 2024, said she had decided to take ⁠a different path after a 17-month stint that included her maiden Wimbledon title last year. However, Thursday’s loss to world number 50 and Polish compatriot Magda Linette at the Miami Open proved a turning point for the six-times Grand Slam winner.
“Miami was challenging for me. I feel disappointment, bitterness and responsibility ‌for ⁠my performance on the court,” Swiatek wrote in a social media post. “I’m grateful for (Fissette’s) support, experience, and everything we achieved together—including one of my biggest dreams ⁠in sport.”
Under Fissette’s guidance, Swiatek adapted her game to faster surfaces, winning titles in Cincinnati and Seoul in addition to her ⁠2025 triumph on the London grass
