Spain’s Carlos Alcaraz got back on track at the ATP Finals with victory over a tormented Andrey Rublev before Daniil Medvedev became the first player through to the semi-finals with victory over Germany’s Alexander Zverev.

Alcaraz eased to a 7-5, 6-2 win to revive his hopes in Red Group after he had opened with a loss to Zverev.

The 20-year-old will need to beat Medvedev in his final group game on Friday although the Russian is guaranteed to progress from the group thanks to a 7-6(7), 6-4 win against Zverev whose last group game is against Rublev.

Questions have been asked about the state of Alcaraz’s game after a slump in from since winning Wimbledon.

But he responded to a three-match losing streak with a confident display, albeit against an unravelling Russian.

“It was a totally different match and level from me. This is the level I have to play if I want to give myself a chance in this amazing tournament,” Alcaraz said after his first win at the tournament.
