Carlos Alcaraz made light of his condition as he dispatched Andrey Rublev in impressive fashion to revive his ATP Finals hopes on Wednesday.

The Spanish four-time Grand Slam champion has been suffering with respiratory issues in Turin and wore pink nasal tape against Rublev during his resounding 6-3, 7-6 (10-8) victory.

In the late match in the John Newcombe group, two-time former champion Alexander Zverev, the world No. 2, underlined his superb late-season form to beat Casper Ruud 7-6 (7-3) 6-3 for his second victory of the week.
