As the weather cools in Canada, and Novak Djokovic and Filip Krajinovic do battle in Vienna, a flashback to warmer, simpler days.
Two years ago at the Rogers Cup, the two countrymen took to the practice court ahead of the tournament.
It was a … stifling hot day. Absolutely brutal.
(As it happened, you can see some random Spanish lefty practicing on the next court – and how sweat-soaked his shirt was).
Here’s what it looked like.
As you can see, Krajinovic was feeling it a whole lot more than his countryman, who was sweaty but looked like he could go another two hours while Krajinovic looked like he was about to keel over.
