Nick Kyrgios turned in a patchy performance to exit the Toronto Masters 7-6 (7/2), 3-6, 6-3 on Monday at the hands of Wimbledon junior winner Denis Shapovalov, reports BSS.
The 17-year-old Canadian set up a match point with his 12th ace, then calmly closed out the upset over the 19th-ranked Australian.
In his first match since losing to eventual champion Andy Murray in the Wimbledon fourth round, Kyrgios at times showed little interest in his on-court duties, serving at lightning speed with only a few seconds between points.
During one changeover, he was heard muttering to himself in dissatisfaction.
The Australian 11th seed somehow struck an ace as his racquet flew from his hand on one serve; he also double-faulted 18 times while managing 13 aces.
Shapovalov, playing in only his second ATP event, will take on Former top 10 contender Grigor Dimitrov, who is trying to claw his way back in what has been a disappointing season.
The Bulgarian reached the second round with a 5-7, 7-6 (7/5), 6-4 win over Yuichi Sugita.
Three other seeds advanced, with number nine John Isner coming back to eliminate Dudi Sela 4-6, 6-3, 6-2.
Australian 12th seed Bernard Tomic beat Alejandro Gonzalez 6-4, 7-6 (7/0) while Jack Sock, the number 16, defeated Denis Kudla 6-2, 6-2.
Dimitrov, ranked 48th, got out of danger against Sugita after trailing a set and a break.
Dimitrov, who lost six straight matches prior to Wimbledon, improved to 21-16 in 2016.
“It was a very tough match, I didn’t play my best tennis but I got through. It was great to hear some Bulgarian voices in the crowd when I got down on myself,” he said.
