World number 12 Belinda Bencic dug deep to overpower Czech Republic’s Marketa Vondrousova 7-5 2-6 6-3 on Saturday and win the Tokyo Olympics women’s singles title, becoming the first Swiss woman to earn an Olympic Games tennis gold.

Bencic, who prevailed in two hours and 30 minutes, can now complete a set of gold medals when she and Viktorija Golubic face Czech No. 1 seeds Barbora Krejcikova/Katerina Siniakova in the doubles final on Sunday.

Despite coming back in the second set, which she won with six points to two, Vondroušová ran into trouble in the third, decisive set of the game.

She managed to get to deuce when Bencic was serving to win the game at 5:3, but the Swiss player managed to press the advantage and won the game.
