Alcaraz swatted at the bees buzzing around him before running for cover and the match was suspended 19 minutes in with Alcaraz serving tied at 1-1.
Dozens of bees attached themselves to the overhead spider camera that traverses the court and a man without any protective covering used a vacuum to clean them off.The players left the court during the delay. When they returned, the chair umpire told them there were still some bees around and Zverev joked that he was fine to play on his side of the court.
The bee vacuumer was summoned back to the court with a spray bottle and was cheered wildly by the crowd. He posed for selfies with fans, causing Alcaraz and Zverev to laugh as they watched him wander the seats spraying for bees. The man also doused the walls around the court.A bee also landed on a player's towel. Alcaraz expressed ongoing concern that the bees would swarm again on his side, but an ATP Tour supervisor encouraged him to give it a try during the warmup.
The match resumed after a delay of one hour, 48 minutes, and Alcaraz went on to a 6-3, 6-1 victory over Zverev to reach the Indian Wells semifinals. Tournament owner and billionaire Larry Ellison and former Microsoft CEO Bill Gates were watching the match from Ellison's box.
