Teenager Coco Gauff became the youngest player to win a WTA title in 15 years with victory in the Linz Open.
The 15-year-old American beat Jelena Ostapenko 6-3 1-6 6-2 and is projected to move inside the world's top 75.
Gauff qualified for the main draw as a lucky loser after losing in the final round of qualifying.
"It has been an amazing week, I hope to come back here again. I will remember this moment for the rest of my life," said Atlanta-born Gauff.
The youngster, who rose to fame at Wimbledon this year when she beat Venus Williams in the first round, emulates Nicole Vadisova, who was 15 when she won her maiden WTA title in Tashkent in 2004.
