• US 18-year-old dismantles Putintseva in dazzling win

• Alcaraz to face De Minaur in men’s quarter-finals

Iva Jovic became the youngest American woman to reach the quarter-finals of the Australian Open since Venus Williams in 1998, by dismantling the Kazakhstani veteran Yulia Putintseva 6-0, 6-1 on Sunday.

At 18, Jovic arrived in Melbourne as the youngest player inside the top 100 and the 27th seed has dominated all opposition, rolling through her four matches without dropping a set. Jovic’s third-round win against the No 7 seed, Jasmine Paolini, was the first top-20 win of her career. Still, Jovic rejected the notion that she is swinging freely with nothing to lose.

• World No 1 claims 7-6 (6), 6-4, 7-5 victory over 19th seed

• Player been making significant changes to service motion

Carlos Alcaraz spent the final 52 minutes of his fourth-round match at the Australian Open chasing down his prey, determined to convert his two-set lead into a straightforward win against Tommy Paul.

As he worked hard to secure the decisive break in set three, Alcaraz put together a flawless serving performance. He won 86% of his first serve points in the set, landing 76% of his first serves. He did not even come close to facing a break point, losing just five service points in total. Alcaraz, the world No 1, closed out his 7-6 (6), 6-4, 7-5 win over the 19th seed Paul with an unreturned serve. He will play Australian Alex de Minaur in the quarter-finals.
