Monte Carlo, April 12 -- Defending champion Carlos Alcaraz lined up a blockbuster Monte Carlo Masters final with chief rival Jannik Sinner after the Spaniard ended the run of local boy Valentin Vacherot with a 6-4, 6-4 win in the last four on Saturday. Earlier, Sinner eased his way into the final for the first time with a clinical 6-1, 6-4 semi-final win over world No.3 Alexander Zverev. It will be the first meeting this season between the world's top two players and will decide who will be world No.1. "I think it's the dream spot for everyone. I'm fighting for a second Monte Carlo title, he's fighting for his first one," said Alcaraz of Sunday's final. "It's going to be a really special one. The No.1 is on the line, which will make tomorrow even more special." The 22-year-old Alcaraz is trying to keep hold of top spot and holds a 10-6 lead over Sinner in the head-to-head series. Alcaraz broke Vacherot three times to wrap up victory in 84 minutes and is bidding for his third title of the season after winning the Australian Open and in Doha. The 24-year-old Italian becomes the first player to reach all three finals of the season's first three ATP Masters 1000 events since Novak Djokovic in 2015. Roger Federer, in 2006, and Rafael Nadal, 2011, are the only two other players to achieve the feat. As in Indian Wells and Miami, Sinner, 24, had the measure of Zverev who has not prevailed in their meetings since the round of 16 at the 2023 US Open. Sinner has lost only one set in his last 21 matches at Masters 1000 events....
