Denis Shapovalov defeats Stan Wawrinka at Japan Open
Denis Shapovalov knocked out former champion Stan Wawrinka in a hard-hitting contest to reach the quarter-finals of the Japan Open.
The Canadian secured a comeback 4-6 6-1 6-4 victory over the three-time Grand Slam champion in Tokyo, eventually sealing the win on his fifth match point.
World No 31 Shapovalov only faced two break points in the one hour and 49-minute encounter as the 19-year-old defeated Wawrinka in their first career meeting.
Wawrinka started strongly as the former world No 3 broke in the third game of the match before taking the initiative as he won the first set without facing a break point.
But Shapovalov responded with back-to-back breaks of his own early in the second set as he forced a deciding set.
The final set was well contested with Shapovalov finally securing the pivotal breakthrough on his fourth break point of the set and despite failing to close out the match from 40-0 on Wawrinka's serve, made no mistake in the following game.
