LONDON, July 5 (Reuters) - Canadian Denis Shapovalov put in a near flawless show to defeat eighth seed Roberto Bautista Agut of Spain 6-1 6-3 7-5 on Monday to book a maiden Wimbledon quarter-final spot.

A single break of serve in the eighth game was enough for a two-set lead for Shapovalov. Both players lost their serve twice at the beginning of the third set before the left-hander surged ahead with a break in the 11th game and then consolidated his advantage to complete the win on his first match point. "I played some really high level tennis today," Shapovalov told reporters. "It"s really, really tough to pick on many things. "Obviously, I got a little bit nervous in the third set. I think it"s completely normal. I dealt with that really, really well. Other than that, I played really, really flawless. Super happy with myself." Next up for the Canadian will be Russian 25th seed Karen Khachanov, who outlasted Wimbledon debutant Sebastian Korda in five sets. read more "I"m very happy with my game. Obviously Roberto is a very, very tough player to play against. To beat him in straight sets at a tournament like this, it backs up my level from Andy"s match," Shapovalov added. "I"m just happy that I feel like I"m improving every single match. Honestly, it"s been really, really fun out there. I feel like everything"s kind of working for me. "Obviously it"s not a guarantee that it"s going to continue like this. But I"m super, super happy with the way I"ve been able to play the last two matches."
