(Reuters) - Carlos Alcaraz said he surprised himself by staying focused despite being stung on the forehead at Indian Wells on Thursday after the Spaniard's quarter-final against Alexander Zverev was interrupted by a swarm of bees.

The world number two was serving in the third game of the match when the bees descended upon him. The 20-year-old tried swatting them away with his racket but eventually ran for cover after being stung.
