British youngster Jack Draper claimed another memorable scalp in the 2022 season as he defeated world number five Stefanos Tsitsipas in the second round of the Canadian Open.
The 20-year-old eased past fellow qualifier Hugo Gaston in the first round before being paired with third seed Tsitsipas, whose glut of errors would cost him in a straight-sets defeat.
Draper won 7-5 7-6 [7-4] on the night, as his Greek counterpart could not kick on after losing the mini-break in the tie-break, posting 36 unforced errors in total during the contest.
World number 82 Draper - who will now meet Gael Monfils of France in the third round - said on the court: "This is why I put in all the hard work, for nights like this on stages like this.
"Last week [after] Washington, me and my coach probably were thinking we weren't even going to come here. We were going to maybe train a week, get a bit of confidence. But it paid off coming.
"I didn't really have much of a game plan. I just thought I needed to play good tennis to beat Stefanos. He's at the top of the game for a reason. [He's] someone I've looked up to the last few years. It's just good to be out here and try to express myself on this stage."
Posting a stellar 85% win rate on his first serve, the world number 39 took three of the five break points available to him in the match to win 6-4 6-4 and set up a third-round battle with Taylor Fritz.
Evans and Draper will also be joined in the third round by British number one Cameron Norrie, who also enjoyed a straight-sets victory in far simpler fashion against Botic van de Zandschulp of the Netherlands.
Despite only posting two aces compared to Van de Zandschulp's six, Norrie eased to a 6-1 6-2 victory on Court Rogers, with his Dutch counterpart only managing a 19% win rate on his second serve.
Home favourite Felix Auger-Aliassime will await Norrie in the third round after closing the day's action with a 7-6 [8-6] 6-4 win over Japan's Yoshihito Nishioka, and there were more shocks to be had on Wednesday.
Defending champion Daniil Medvedev will soon lose his grip on the crown after a 7-6 [7-1] 4-6 2-6 defeat to Wimbledon runner-up Nick Kyrgios, while second seed Carlos Alcaraz Garfia was beaten in three sets by Tommy Paul.
In the women's tournament, Serena Williams's run came to an end in a 2-6 4-6 defeat to Belinda Bencic as she prepares to retire after the US Open, while Iga Swiatek, Simona Halep and 2021 champion Camila Giorgi - who beat Emma Raducanu in round one - all advanced.
