Kyrgios shocks Medvedev as Serena bows out at US Open

Canada beat Australia in the final of the Davis Cup in Malaga to win the event for the first time in their history. They got off to a strong start as Denis Shapovalov beat Thanasi Kokkinakis in straight sets 6-2 6-4.

Wimbledon runner-up Nick Kyrgios beat Daniil Medvedev in an enthralling match in New York 7-6 (13-11) 3-6 6-3 6-2 to reach the quarter finals of the US Open. Medvedev was the defending Champion and current World No 1 and was the favourite heading into the match. However, Kyrgios was able to produce some scintillating tennis which proved to be a extremely entertaining encounter in front of 24,000 people in the Arthur Ashe Stadium.

Kyrgios is yet to win a major tournament but he has been in impressive form recently and will be hoping he can finally claim a maiden Grand Slam. He will now face Russian 27th seed Karen Khachanov for a place in the semi finals.

After losing the match Medvedev will lose his World No 1 status when the rankings are updated next week.

Meanwhile Serena Williams waved farewell to the sport after losing to Australia’s Ajla Tomlijanovic 7-5 6-7 (4-7) 6-1. Williams announced before the tournament that the US Open will be her last competitive event. Her retirement brings to an end an illustrious 27-year professional career which includes 23 major titles. The former World No 1 received a standing ovation at the end of the match which sparked an emotional reaction from Williams. She will be recognised as one of the greatest female tennis players of all time.
