The 2026 Rolex Monte-Carlo Masters is underway at the Monte-Carlo Country Club, and the clay-court action really heats up on the French Riviera. We’ve broken down the day’s best tennis betting picks for Monte-Carlo, digging into matchup tactics, surface tendencies, and current form to find the sharpest edges on the board. Whether you’re betting the moneyline, game spread, set spread, or total, our 2026 Monte-Carlo Masters best bets are built to help you profit. I’m dropping some of my favorite plays below, but make sure you also monitor the picks page throughout the day. I generally have a few more picks over there, plus I occasionally add plays based on how lines are moving. That’s also where Gill Alexander posts his best bets.

Stan Wawrinka vs. Sebastian Baez

Baez turned in some strong results to start the year, but he’s just 7-6 since the start of the Golden Swing. He has been somewhat disappointing on clay this year, dropping matches against players like Jaime Faria and Titouan Droguet. That has to give Wawrinka the belief he needs to go out there and give Baez a match. I’m a little worried about Baez’s ability to extend rallies and keep matches physical. He could ultimately tire a 41-year-old Wawrinka out. But I think Wawrinka has the power to push Baez around, and the slower conditions will make life easier on the three-time Grand Slam champion as a mover.

Bet: Wawrinka +1.5 Sets (-134 – 1.5 units) & Wawrinka ML (+200 – 0.5 units)

Daniel Altmaier vs. Tomas Machac

Altmaier likes slower clay-court conditions, as opponents aren’t able to easily break down his one-handed backhand. Altmaier is also good at playing with heavy topspin, and he’s comfortable playing from deep in the court. All of that has made him a dangerous player when working as a small underdog on this surface. Well, with that in mind, I’m taking a shot on Altmaier to eliminate Machac. The Czech is undoubtedly the more talented player here, but he’s just 8-7 since the start of the season. He’s underperforming given the weaponry he possesses, and he’s least reliable in ugly, physical matches. So, if Altmaier can muck this one up — and force a decider — the German can steal a win.

Bet: Altmaier ML (+131)

Matteo Arnaldi vs. Cristian Garin

Arnaldi really doesn’t belong in the main draw, as he lost his second qualifying match to Alexandre Muller. However, stuff happens. Arnaldi now has a shot at advancing to the Round of 32, and he probably likes this draw. However, Arnaldi hasn’t won a single main-draw match since the start of 2026. There’s nobody that played at a decent level in 2025 that is playing worse in 2026, and Garin should be able to take advantage of that. The Chilean has been playing a ton of clay-court matches dating back to the end of last year, and he looked great in a straight-set qualifying win over Nikoloz Basilashvili to book his spot in the main draw. I simply feel a little better about where Garin’s game is right now, and his 91 ATP-level clay-court victories speak for themselves.

Bet: Garin ML (-159)

Alexander Blockx vs. Denis Shapovalov

Every couple of weeks, we get a run from Shapovalov that makes it seem like the Canadian is back to performing like a top-20 player. However, the southpaw still struggles mightily with inconsistency, and he’s least reliable when playing in rough conditions. He needs a good deal of control in order to play his aggressive style of baseline tennis, and wind can give him issues with double-faults. With that in mind, I think this is a good draw for Blockx, who possesses some serious ball-striking ability.

Bet: Blockx ML (+100)

Francisco Comesana vs. Flavio Cobolli

Cobolli’s 2026 season hasn’t been as disappointing as Arnaldi’s, his fellow countryman. However, the Italian is just 9-8 since the start of 2026, his serving accuracy hasn’t been as sharp as it has been in previous seasons, and he’s really struggling to see the ball as a returner. Well, Cobolli will now play his first clay-court match of the season, and he’ll be doing it against a clay-court specialist. Comesana also happened to look awesome in qualifying, beating Romain Arneodo and Ethan Quinn in straight sets. I believe he’ll have what it takes to give Cobolli a tough match, making the Argentine a worthy flier at +130. Comesana can play defense, but he packs more punch than you’d think for a player his size.

Bet: Comesana ML (+130)
