Coco Gauff takes first major scalp in reaching last four of Upper Austria Ladies Linz

The 15-year-old American needed a lucky loser spot to get into the main draw but has taken her opportunity superbly, and a 7-6 (1) 6-4 victory over world number eight Kiki Bertens gave her the biggest win by ranking of her fledgling career.

Gauff, who was already guaranteed to break into the top 100 on Monday, is the youngest woman to reach a WTA Tour semi-final since Nicole Vaidisova won Tashkent in October 2004.
