NEW YORK (Reuters) -Canadian teenager Leylah Fernandez continued her U.S. Open dream run on Tuesday by storming into her first Grand Slam semi-final with a battling 6-3 3-6 7-6(5) win over Ukrainian fifth seed Elina Svitolina.

It was yet another upset win for Fernandez but hardly a shock considering she had already knocked out four-time major champion Naomi Osaka in the third round and three-time Grand Slam winner Angelique Kerber in the fourth.
