Tennis: Can Jannik Sinner overtake Carlos Alcaraz and become world No. 1 in Monte-Carlo?

The start of the clay tennis season provides the perfect battleground for Jannik Sinner to challenge Carlos Alcaraz for the men’s world No. 1 ranking.

Having trailed by more than 3,000 points after the Australian Open, Sinner’s ‘Sunshine Double’ – victories at Indian Wells and the Miami Open - have put him in touching distance of top spot heading to the next ATP Masters 1000 event in Monte-Carlo.

The Italian arrives on the French Riviera with a deficit of 1,190 points and nothing to defend, after missing the 2025 edition due to his three-month suspension for failed doping tests. Reigning champion Alcaraz, meanwhile, has the maximum 1,000 points to reclaim.

Sinner and Alcaraz’s duel for the top spot always carries significance, even more so with the need to reacclimatise to the clay for the next Grand Slam, Roland-Garros, in late May.

The top-seed confidence boost would be crucial for Sinner, returning to the site of his crushing French Open defeat last season. That should not take away from his prowess on clay, where he won 11 matches in 2025 and lost only twice, both times to Alcaraz.

Tennis’ duopoly have yet to cross paths this year after six tour-level meetings in the 2025 campaign. Alcaraz remains on top after two titles in February, but a second-round exit in Miami and Sinner’s U.S. delight have opened up the race to the top.

Monte-Carlo Masters – how Sinner can reclaim world No. 1 ranking

As players switch from the hard surface to red clay, could we also see a switch in the top-ranked men’s singles player? The short answer is yes: Sinner could reclaim the No. 1 ranking spot for the first time since November 2025.

First, the Monte-Carlo second seed must at least reach the semi-finals in Monaco, otherwise Alcaraz returns home for the Spanish tournaments in Barcelona and Madrid as No. 1.

From thereon, Sinner can outperform his rival and claim the top spot – for example, if he were to reach the ATP Masters 1000 final and Alcaraz did not. That also applies to the final and a possible earliest showdown on Court Rainier III on Sunday (12 April).

To avoid worrying about permutations, Sinner can focus on winning his maiden Monte-Carlo title – victory in the final would return the 24-year-old to the summit of the ATP rankings come next week.

The world No. 2 currently holds a 19-2 record in the 2025 campaign going into the clay swing, yet he has just one tour-level title on the surface. That came four years ago at the ATP 250 event in Umag, against none other than Alcaraz.

There is plenty more tennis to play across the season, though what a boost it would be for Italy’s history maker to reclaim his ranking crown at this stage. With two trophies from his last two outings, Sinner will go for a Masters hat-trick in Monte-Carlo.
