Carlos Alcaraz and Jannik Sinner are set to meet for the third time on the ATP tour on Sunday, facing off against each other in the final of the 2022 Croatia Open in Umag.While Alcaraz held off a spirited display from Italian Giulio Zeppieri in the semifinals to advance to the summit clash, Sinner had a much easier time taking care of compatriot Franco Agamenone in his penultimate match.With their head-to-head record tied at 1-1, tennis fans on social media are more than excited to see what the showdown in Croatia between two of the best youngsters on tour at the moment has to offer. Interestingly, this is the first time the duo will be squaring off on clay, as their first encounter came on hardcourt -- at the 2021 Paris Masters, where the World No. 5 prevailed in straight sets.Tennis TV@TennisTVMOUTHWATERING FINAL @carlosalcaraz @janniksin #CroatiaOpenUmag1302110MOUTHWATERING FINAL 😍@carlosalcaraz @janniksin #CroatiaOpenUmag https://t.co/LysNd7ez23Their second clash came much more recently -- earlier this month at the Wimbledon Championships, where Sinner powered through in four sets. The Italian, therefore, has a lot of backing to do the same on Sunday as well, despite the fact that clay is often considered to be the Spaniard's best surface.Most fans were excited about the clash regardless of who turned out to be the eventual winner, saying that it was good to see the youngsters stepping up and proving that they have what it takes to become the next big thing.
