Usain Bolt is the fastest man in history. But the sprinting legend is used to running for the finish line, not a tennis ball.

Bolt got some practice with the latter on Thursday at the Rolex Monte-Carlo Masters, where he was in the stands for Jannik Sinner‘s win against Hubert Hurkacz. When Hurkacz mishit a forehand that soared into the crowd, it was Bolt who searched for and secured the ball, quickly returning it to Court Rainier III. 

On your marks, set, GO 🚦

Bolt also met Holger Rune at the Monte-Carlo Country Club. The Dane will play Daniil Medvedev or Alexander Zverev in the quarter-finals.

“How cool is this 🤗 an honor to meet you
@usainbolt,” Rune tweeted.

It was not the first celebrity appearance of the week at the ATP Masters 1000 event. Novak Djokovic met Formula 1 star George Russell on Tuesday.
