"Being No.1 is pretty cool" - Gauff on becoming number one doubles player in the world

Coco Gauff captured the Toronto doubles trophy with Jessica Pegula and it allowed the young American to debut her new doubles rankings - number one.

Gauff emerged ahead of Shuai Zhang as the best doubles player in the world after another strong run for the American. She's won a couple of trophies, played in two finals (US Open last year and French Open this year) and it's something she thinks is pretty cool:

"Being No.1 is pretty cool. I have no words. ... I didn't really know it was coming this week and what I had to do. But [Pegula] told me yesterday. As a kid, I'm going to be honest with you, I didn't even know there was separate rankings for singles and doubles. But when I got on tour and when I realized I could do well in doubles, yes. ... I wanted to. I mean, who wouldn't want to be No.1 in anything?"

Her partner Pegula was rather happy about it too and she's not too shabby herself being ranked in the top 10 of both singles and doubles as of today:

"I'm so glad that I could help [Gauff] get there today. I think we're No. 1 in the Race and the top two Americans in singles. So it's been a pretty cool little journey that we're on together, even though I'm ten years older."
