COCO GAUFF is a Grand Slam champion in singles and doubles, something she did not expect to happen so soon.

The 20-year-old American won her first major doubles title today by teaming with Katerina Siniakova for the French Open trophy. They defeated Italians Jasmine Paolini and Sara Errani 7-6 (5), 6-3, giving Gauff her second major after winning the US Open singles last year.

“I think it’s just one of those things that when you least expect it to happen, it happens,” Gauff said, reflecting on her doubles triumph.
