A superb performance on Friday from world number 2 Carlos Alcaraz earned the Spaniard a 6-4, 6-4 victory over Russian Daniil Medvedev to secure his place in the last four of the ATP Finals. Despite losing to Alexander Zverev in the opening match, Alcaraz tops the Red Group and will face Green Group runner-up Novak Djokovic in a mouth-watering semi-final. The other semi-final will pit Medvedev against local favorite Jannik Sinner.
