The 2019 FIFA Women's World Cup just started on Friday, and the WTA's top players paid tribute by trying to do their best at keepy ups. The goal was to juggle using their body and feet, but with a slight twist, instead of a soccer ball they used something a little more familiar.

Simona Halep crushed the competition with her fancy footwork and a smaller ball, juggling 51 in a row. Sloane Stephens didn't fare too well. She only managed one, but ended the challenge with a great kick.

The United States women's soccer team is slated to play against Thailand on Tuesday in their opening match.
