Tennis player Coco Gauff, 15, reaches her first WTA final

American teenager Coco Gauff advanced to her first WTA final by beating Andrea Petkovic 6-4, 6-4 on Saturday at the Upper Austria Ladies in Linz.

The 15-year-old Gauff saved nine of 10 break points against her German opponent.

Gauff did so with a straight-sets victory over the eighth-ranked Kiki Bertens, the first time she has beaten a top-10 opponent.

Gauff faces 2017 French Open champion Jelena Ostapenko in the final. The Latvian saved three match points to beat eighth-seeded Ekaterina Alexandrova 1-6, 7-6 (5), 7-5.

Zverev ended 11th-seeded Italian Matteo Berrettini’s run by taking their semifinal 6-3, 6-4, ending the match on an ace, one of 11 he had.
