Carlos Alcaraz has been in scintillating form ever since returning from injury. He is yet to taste defeat in 2023 and has won all seven matches he has competed in.The Spaniard faced Dusan Lajovic in the quarterfinals of the Rio Open on Friday (February 25), where he regrouped after falling 2-4 in both the first and second sets to get the better of his opponent. Should he go on to clinch the title in Brazil, Alcaraz will join World No. 1 Novak Djokovic with 7,070 points in the ATP rankings. Having registered such an impressive and fast-paced comeback on tour, fans have expressed nothing but admiration for the youngster. One fan opined that Alcaraz was the "best thing to happen to men's tennis" and that he was a "total generational package.""Carlos Alcaraz is simply the best thing to happen to Men’s Tennis at the perfect time. He is capable of taking your breath away each time. The speed and court coverage is a joke. He’s explosive, exhilarating, youthful, & has a charismatic personality. Total generational package," a fan said.Vansh@vanshv2kCarlos Alcaraz is simply the best thing to happen to Men’s Tennis at the perfect time. He is capable of taking your breath away each time.

It will be the first meeting for the duo on tour.Jarry comes into the contest on the back of an impressive win against sixth-seed Sebastian Baez in the quarterfinals. Meanwhile, Alcaraz will be hoping to continue his perfect run in 2023 and will be keen to defend his title. He defeated Diego Schwartzman in the final last year to clinch the trophy.With second-seeded Cameron Norrie looking strong on the other side of the tie, a face-off between Alcaraz and the Brit for the second time in a final in as many weeks is well on the cards. The duo faced each other at the Argentina Open last week and it was the Spaniard who got the better of the top-ranked Brit (6-3, 7-5) to clinch the title.
