Final Preview: Alcaraz & Sinner In Winner-Takes-All Showdown

Like the great tennis rivalries that have come before, whenever we get a new chapter in the Carlos Alcaraz vs. Jannik Sinner head-to-head series, history is typically on the line.

But seldom do we get a meeting with stakes as high as those in Sunday’s Rolex Monte-Carlo Masters final (3 p.m. CEST/9 a.m. ET).

For just the fifth time in the past 10 years, one match will decide which of the two competing players emerges World No. 1. Both the incumbent, Carlos Alcaraz, and the challenger, Jannik Sinner, have spent 66 weeks atop the PIF ATP Rankings during their careers. Sunday’s championship match will break that tie.

When No. 1 was on the line in last year’s US Open championship match, Alcaraz won in four sets and would go on to finish the year as World No. 1.

“I think it’s the dream [final] for everyone,” Alcaraz said after his semi-final victory against Valentin Vacherot Saturday. “I’m fighting for a second Monte-Carlo title, he’s fighting for his first one.”

“It’s going to be a really special one. The No. 1 is on the line, which will make tomorrow even more special.”

When Alcaraz completed the career Grand Slam at the Australian Open and won Doha as part of a 16-match winning streak to start the year, he led Sinner by more than 3,000 points. Sinner would not have expected to be in a position to wrestle back No. 1 this early in the season. But back-to-back titles in Indian Wells and Miami and a run to his first Monte-Carlo final – where Alcaraz is defending 1000 points – have made the dream a reality.

Carlos. Jannik. Monte-Carlo Final.

Sinner is attempting to become the first player since Novak Djokovic in 2015 to sweep the first three Masters 1000 titles of the season and to join Djokovic and Rafael Nadal in winning four straight, given that he won the Rolex Paris Masters late last year.

When the pair last met on clay, Alcaraz saved three championship points to win the Roland Garros final in a fifth-set tie-break. As Sinner also looks to complete his career Grand Slam in Paris this year, he will be highly motivated to claim victory over Alcaraz in Sunday’s final.

“It would be good for me before Paris to play at least once against him, seeing where my level is on this surface and where we need to work on, which gives me hopefully good feedback,” Sinner said. “In any case, if I win or lose, it’s going to be good feedback and a good point where we need to improve.”

Astonishingly, the players have both won 1,651 points against each other. But Alcaraz’s 10-6 lead in their rivalry — including 3-1 on clay — is what matters most. Both players have won 26 titles.

Alcaraz and Sinner have combined to win the past 19 tournaments in which both of them have been entered. On Sunday, that streak will hit 20.

The only question is which player will be the one to extend it.
