Carlos Alcaraz said Saturday his burgeoning rivalry with Jannik Sinner brought out the best in him, with the Spanish star driven by winning more Grand Slam titles and toppling the Italian as World No. 1. 

The 21-year-old clinched both Roland-Garros and Wimbledon last year and is preparing to take Melbourne Park by storm and lift the Australian Open to complete a career Grand Slam of all four majors. “When I’m facing him, I just know that I have to play my best if I want to win. That’s it. Probably if I have a bad day against Jannik, it’s 99 percent that you’re going to lose,” said the Spaniard.
