Pics: Teens Coco and Bibi try out Arthur Ashe

FLUSHING MEADOWS, NY – Saturday is a big moment in the careers of teenagers Bianca Andreescu and Coco Gauff.

Andreescu, the 19-year-old from Canada, will make her Arthur Ashe Stadium debut – in her US Open main draw debut – as she takes on No. 19 seed Caroline Wozniacki during the day session.

And on Saturday night, 15-year-old Gauff, who played her first two rounds in the (very large) Louis Armstrong Stadium – will also hit the biggest stage in tennis for a highly publicized match against defending champion Naomi Osaka.

On Saturday morning, they both got a bit of a taste of the big stadium.

And they even ran into each other on the crossover, and greeted each other warmly.

Here’s what it looked like.
