US Open finalist Leylah Fernandez out of Roland Garros

Unseeded Italian Martina Trevisan has dumped US Open finalist Leylah Fernandez out of the French Open.

Trevisan beat the 17th seeded Canadian 6-2, 6-7 (3), 6-3 to progress to her first grand slam semi-final.

Trevisan had every one of the responses as she ruled the majority of the match against a less than impressive Fernandez

 who battled to rehash the structure that took her to last year's US Open last.

The world No.59 might have won in straight sets however faltered while serving for the match at 5-4 ... the second as individual left-hander Fernandez dug profound to remain in the challenge

Fernandez comfortably claimed the tiebreak to become the first player to take a set off Trevisan at Roland Garros this year, but it was to prove only a brief respite.

Trevisan dashed into a 3-0 lead in the choice set and won a furiously challenged fourth game to procure a twofold break.

Fernandez, who was treated for a foot injury in the first set, was never going to go away quietly though, and broke serve twice herself to claw back to 3-5.

The nerves were clear as Trevisan again served for the match yet this time she wouldn't be denied as she secured the win with an angled crosscourt forehand.
