Costa Rica Goalie Keylor Navas Practices By Saving Tennis Balls

Costa Rica have been the surprise of the World Cup this far, thanks large in part to goalie Keylor Navas. His heroics lifted the small country past Greece in a shootout and earned a date with juggernaut Netherlands in the quarterfinals.

Navas will have his hands full with the Dutch squad, so he enlisted the help of pro tennis player Pablo Andujar to help him train.

Saving a blistering tennis shot is much more difficult than a soccer ball — and much more hilarious.

We will see if the unorthodox drill paid off on Saturday.*

*Spoiler alert: The Netherlands are going to roll.
