Carlos Alcaraz had his drop shot working and overcame physical issues to claim a 6-3, 7-6 victory over Andrey Rublev at the ATP Finals.

The ATP Finals’ organizers have already published the order of play for Day 6: Alcaraz and Zverev will face each other in the day session, while Ruud and Rublev will clash in the night session.

The ATP has listed various scenarios that could help Alcaraz qualify for the final four. The most intriguing one is that if Alcaraz defeats Zverev in straight sets and Ruud beats Rublev in three sets, the Spaniard would win the group and Zverev would finish second.
