Leylah Fernandez has done it again. The 19-year-old took down fifth-seeded Elina Svitolina in the quarterfinals at the US Open on Tuesday to reach her first Grand Slam semifinal.

Fernandez won the first set 6-3 before losing the next 3-6. In the third, Svitolina refused to go quietly, fighting Fernandez all the way to a third set tiebreak.

It was in that tiebreak that Fernandez took the match 7-6(7).

With the win, Fernandez becomes just the third Canadian to reach a Grand Slam semifinal. She’s also the youngest player to defeat two WTA Top-5 players at the same major since 17-year-old Serena Williams at the 1999 US Open.
