Novak Djokovic swatted aside Alexander Zverev to become the oldest French Open semi-finalist in 57 years. The 38-year-old was trailing Zverev by a set when the German accidentally swallowed a fly. Zverev, who lost in last year’s final to Carlos Alcaraz despite leading two sets to one, promptly choked again as Djokovic won 4-6 6-3 6-2 6-4.

Novak Djokovic and Alexander Zverev are bugging out during their French Open quarterfinal. Both players have been bothered by little flies that are zooming around Court Philippe-Chatrier as they compete Wednesday night.

Novak Djokovic said beating Alexander Zverev on Wednesday was a "testament" to his ability to compete at the highest level as the 38-year-old reached the semi-finals at Roland Garros to inch closer to a record 25th Grand Slam title.
