Iga Świątek and Jannik Sinner, threatening title aspirants, reaffirmed their reputations with their brilliant performances in the fourth round as both eliminated their respective opponents in straight sets. 

Sinner Dismantles Bublik in 81 Minutes

In an exhibition of high-class tennis by the world number one Sinner and defending champion, he saw his opponent Alexander Bublik in 6-1, 6-1, 6-1 for the 81-minute romp. He swapped Bublik with the counter of eight breaks of serve, with Sinner striking a total of 24 ground-stroke winners, not having a sweat on Bublik's serve all evening. This would imply that Sinner had one aim and one target in mind: his own serve.

There's a high chance of Sinner facing yet another paint-marking quarter-final against Lorenzo Musetti, with pride and panache as the likely contenders. 

He has, however, slipped only a single set here and remains incorrigible at last year's title in deathly sharpness. 

Świątek Steps Up Against Alexandrova

At first, Iga was a little shaky on her serve but thereafter found her rhythm to dispatch Ekaterina Alexandrova swiftly, 6-3, 6-1. The Polish star dictated rallies with her bomb serves, cracking forehands with intent and leaving Alexandrova mostly playing defense. 

Iga has shown definition this year in her ability to seize and adapt; her mixing pressure with calm authority has only made Monday's win that much stronger. She will face Amanda Anisimova in the quarter finals.

Świątek has now passed the incredible mark of losing only 14 games in total throughout her four matches in this US Open, thus further enhancing her record. 

Both Sinner and Świątek have booked their eighth spots in the guaranteed blockbusters coming up. For Sinner, it is the title defense, and for Świątek, yet another try at a major, both growing larger in context this year, given their form.
