World number 13 Denis Shapovalov crashed out of the ATP Auckland Classic Thursday, beaten in straight sets by French qualifier Ugo Humbert.
There was only one break in each set of the evenly contested clash with Humbert winning 7-5 6-4, clinching the victory with the Canadian's sixth double fault.
"I'm really, really, happy, it's one of the biggest wins of my career," the 57th-ranked Humbert said as he advanced to a semi-final showdown big-serving American John Isner.
"I tried to play each ball, I tried to stay focused and my plans were working."
"That match point, I played it very aggressively and very well. Winning a match like this can give me a lot of confidence going forward for the rest of this tournament, the Australian Open and for the rest of the year."
