Videos - Ruud to Kyrgios: "Who would have thought?"
The World Tennis League is an exhibition unlike any other. The team competition features original confrontations, each played over a single set.
So, after seeing Iga Swiatek and Paula Badosa team up in doubles, spectators were treated to a pair no one ever thought they'd see: Nick Kyrgios and Casper Ruud.
Asked about the situation on court, the Norwegian quipped: "When we started the match, we thought: 'Who'd have thought we'd be playing doubles together?'"
