It makes sense given that the best the 19-year-old Canadian has done in Grand Slam singles is a third-round finish. Watch that incredible moment ahead, and see it captured in powerful photos as well. "I was only thinking of trusting myself, trusting my game," Fernandez said in a post-match press conference.
