Djokovic's Rogers Cup hopes crushed by teenager Tsitipas
Wimbledon champion Novak Djokovic saw his bid for a fifth Rogers Cup triumph ended by a shock third-round defeat at the hands of Greek teenager Stefanos Tsitsipas in Toronto.
Tsitipas, who turns 20 on Sunday, beat the 13-time Grand Slam champion 6-3 6-7 (5-7) 6-3 in two hours 18 minutes.
The World No.27 is through to the first ATP World Tour Masters 1000 quarter-final of his career.
Kevin Anderson and Grigor Dimitrov are also through to the last eight.
South Africa's Anderson, who Djokovic beat in this year's Wimbledon final, saw off Belarus' Ilya Ivashka 7-5 6-3.
Dimitrov beat Frances Tiafoe of the United States 7-6 (7-1) 3-6 7-6 (7-4).
British No.1 Johanna Konta moved into the Rogers Cup third round by beating two-time Grand Slam champion Victoria Azarenka in a match that was halted by rain on Wednesday.
Konta led 6-3 3-0 when play was stopped in Montreal, and completed a comfortable victory yesterday. The 27-year-old went on to win 6-3 6-1 after immediately breaking Azarenka's serve once play was resumed.
