Although rublev

John Newcombe Group: Spain's Carlos Alcaraz brought his trademark energy back to the court on Wednesday at the ATP Finals, overcoming Andrey Rublev 6-3, 7-6(8) in a preliminary group match. The win was a vital response from the Spaniard, who had dropped his opening match to Casper Ruud after dealing with a stomach issue.

This year Alcaraz has won two Grand Slam singles titles, the French Open and Wimbledon, within a few weeks. But had an up-and-down performance in the second half of the season.

On Wednesday, despite not feeling fully recovered, Alcaraz's performance was all about resilience as he lifted his game to clinch victory in 96 minutes.
