Kyrgios' best chance as top seeds tumble at the US Open
The tennis world is in shock after three of the top 10 male stars have tumbled at the US Open in the beginning round.
Dominic Thiem (4), Stefanos Tsitsipas (8) and Roberto Bautista Agut (10) all faced unthinkable lossed in New York on Tuesday.
World number 43, Russian Audrey Rublev upset eighth-seeded Tsitsipas on 6-4, 6-7(5), 7-6(7), 7-5 Tuesday and knocked him out and will go on to the second round.
Fourth seed Dominic Thiem, who was dubbed the young gun, went down in four sets to Italy’s Thomas Fabbiano 6-4 3-6 6-3 6-2 - meaning Gael Monfils is the highest-ranked player remaining in his quarter of the draw.
What left crowds stunned was the death of 10th seed Roberto Bautista Agut.
The Spanish star made it to the quarter finals of the Australian Open and the semi-finals at Wimbledon this year, however he fell five sets to Mikhail Kukushkin 3-6 6-1 6-4 3-6 6-3.
Thiem and Tsitsipas’ incredible losses meant they both had first-round defeats in back-to-back grand slams - similarly to Wimbledon.
Nick Kyrgios who is one of the toughest opponents, will continue on to compete for the championship title.
The 24-year-old Australian has an even wider door to make it to a major semifinal.
The knock out of three of the top ten seeds in the opening rounds could mean Nadal's path to the US open crown becomes much easier.
