Carlos Alcaraz sets the internet on fire with shirtless training session

Spanish tennis superstar Carlos Alcaraz set the internet on fire with a shirtless training session after defeating China's Yibing Wu in straight sets on Friday.

As the defending champion from Murcia continues his run at the US Open, the season's fourth and final Grand Slam, played on hard court, his videos without a T-shirt have gone viral.

Alcaraz has now reached the last 16 of the New York major and will aim for a quarterfinal spot in what promises to be a stern test against American Tommy Paul, the first-seeded player (No. 20) Alcaraz will face in the tournament.
