Grigor Dimitrov was put the test in 'Five To Win', with the Bulgarian fielding a range of questions about his ATP Tour career and more.
The quiz has a few simple rules, but it's not clear how well Dimitrov understood them: While they were being explained, the fan favourite broke into a laughing fit that set the stage for a fun examination.
"I've got the giggles!" Dimitrov told the producer, before he composed himself for the task at hand.
With the help of a hint, Dimitrov correctly guessed his longest ATP Tour match. But he was not convinced the stat was true: "Check those facts, maybe," he said.
