Rafael Nadal was left concerned by a breathing problem and sad at the end of his remarkable winning run after a final defeat to Taylor Fritz in Indian Wells.

The 35-year-old had won his first 20 matches of the season, claiming three titles including a 21st grand slam crown at the Australian Open, and was the favourite to win the first Masters event in 2022.
