MADRID: World number two Aryna Sabalenka made light work of 16-year-old Mirra Andreeva on Monday (May 1) with a 6-3, 6-1 win to reach the Madrid Open quarter-finals.
In the men's tournament world number three Daniil Medvedev beat his friend and Russian compatriot Alexander Shevchenko, while Frances Tiafoe crashed out against Pedro Cachin.
Russian youngster Andreeva, a wildcard, became only the third 15-year-old to win a WTA 1000 main draw match when she beat 2021 US Open finalist Leylah Fernandez last week.
She went on to beat two top 20 players in Beatriz Haddad Maia and, on her 16th birthday, Magda Linette, but overcoming 2021 Madrid winner Sabalenka was a bridge too far.
"Of course I'm happy with the win, I wish I would have played at Madrid when I was 16," said Sabalenka.
"I think my first few games I was trying to adjust for her rhythm and her game, and then I kept trying to play my game, be aggressive and fight for every point."
Sabalenka broke Andreeva in the first game but the world number 194 immediately responded to get back on serve.
The Belarusian converted her second break point in the fifth game for a 3-2 lead after Andreeva double faulted, and again broke to clinch the first set 6-3.
Sabalenka, second seed in Madrid, won 67 per cent of points in a convincing second set to reach the last eight.
The Australian Open champion will face Egyptian Mayar Sherif in the next round after she beat Elise Mertens 6-4, 0-6, 6-4 earlier Monday.
Sherif, 26, is the first Egyptian to reach a WTA 1000 quarter-final.
World number nine Maria Sakkari beat home favourite Paula Badosa 6-4, 6-4 to set up a quarter-final clash with Romanian Irina-Camelia Begu.
Veronika Kudermetova beat Daria Kasatkina in a tight all-Russian battle 7-5, 1-6, 7-2 (7/2) and will face world number three Jessica Pegula or Martina Trevisan on Wednesday.
MEDVEDEV THROUGH
In the men's competition second seed Medvedev, 27, edged out his friend Shevchenko 4-6, 6-1, 7-5 on Monday to reach the Madrid Open fourth round.
The Russian duo enjoyed six years of online gaming sessions together before they eventually met last year, facing off against each other in the Spanish capital for the first time in a thrilling two hour 42 minute clash.
Medvedev, who readily admits he struggles on clay, started slowly but showed his quality to win back-to-back matches in Madrid for the first time.
Shevchenko, 22, saved one match point but Medvedev triumphed with a forehand winner to reach the last 16, where he will face Aslan Karatsev, who beat Alex de Minaur 6-3, 4-6, 6-4.
"When you win 7-5 in the third, it's always mentally a brutal match, so I'm happy that I managed to win it," said 2021 US Open winner Medvedev.
"I don't have a title on clay yet, I really want to make it.
"But I'm also trying to play only the best tournaments, so it's tougher because all the best tennis players in the world (are there)."
Argentine player Cachin, ranked 67th, took out world number 11 Tiafoe with a 6-1, 7-6 (7/2) victory and will face lucky loser Jan-Lennard Struff in the next round.
Tiafoe's countryman US baseliner Taylor Fritz saw off Cristian Garin 6-1, 7-6 (7/4).
