World number two Carlos Alcaraz retained his Madrid Open title with a three-set victory over Germany’s Jan-Lennard Struff.

The 20-year-old Spaniard won 6-4 3-6 6-3 for his fourth trophy on the ATP Tour this season, and 10th overall.

Alcaraz is the second man to defend his title in Madrid, after compatriot Rafael Nadal did so in 2014.

Alcaraz’s victory in Madrid means he has won back-to-back tournaments, having won the Barcelona Open in April. He will replace Novak Djokovic at the top of the world rankings by simply playing in Rome next week.
