The 15-year-old American Coco Gauff beat Jelena Ostapenko 6-3 1-6 6-2 to becomes the youngest ver tour winner and will shoot up the rankings to 75 in the world.
Gauff only qualified for the main draw as a lucky loser after losing in the final round of qualifying.
Her father and coach, Corey Gauff, then came onto court to give his daughter some encouragement. He said: “Just relax, you’re not going to sprint to the finish line, you’re going to walk to the finish line.
“Trust your shots. Calm down, take your mind to another place, to a practice match. Just play, don’t think about negatives just think about positives. Yesterday if you know you had 5-2 you’d take that, you’re in control.”
She immediately broke back, winning the match and title when Ostapenko sent a forehand long.
“Thank you so much to my family and team for their support, you are always with me every step of the way,” she said.
