TORONTO (AP) Denis Shapovalov upset Australia's Nick Kyrgios 7-6 (2), 3-6, 6-3 on Monday night in the first round of the Rogers Cup men's tennis tournament.
Shapovalov said afterward that he didn't expect to win.
Backed by a hometown crowd, the Richmond Hill, Ontario, native took advantage of world No. 19 Kyrgios's unforced errors on a beautiful evening that featured a light breeze at Aviva Centre.
In a late match, American Sam Querrey defeated 7-6 (5), 6-4 Frank Dancevic, of Niagara Falls, Ontario.
Shapovalov, who is a wild card in the tournament, was coming off a boys' singles title win at Wimbledon earlier this month. The tournament's youngest player will face Grigor Dimitrov of Bulgaria in the second round.
