French Open Tennis Picks: Upset Alert
Moise Kouame (+249) vs. Adolfo Daniel Vallejo
Kouame became the youngest man since 1991 to win a main-draw match at the French Open, and the 17-year-old Frenchman did so in convincing fashion, beating former Grand Slam champion Marin Cilic, 7-6 (4), 6-2, 6-1, while saving all seven break points faced. He'll have the adrenaline flowing again playing in Paris and can continue to swing freely against the 22-year-old Vallejo, who is also in uncharted territory in the first Grand Slam second-round match for both players. Vallejo's first-round win came thanks to a Cameron Norrie rib injury, as Norrie retired in the second set, so the 71st-ranked Paraguayan has yet to prove himself in a full best-of-five set match.
Diane Parry (+198) vs. Ann Li
Parry has played some strong tennis in her home country this month, as she won a WTA 125-level event at the Clarins Open in Paris and notched a top-40 win over Emma Raducanu in Strasbourg before overcoming a first-set bagel to beat Anhelina Kalinina 0-6, 6-2, 6-4 in the first round here. The 23-year-old Frenchwoman has reached the third round at all four Grand Slams, so she's certainly capable of outplaying her current ranking of No. 92, while the 29th-ranked Li has found limited success on the biggest stage, with a 3-3 career record at Roland Garros and a 14-16 mark in Grand Slams overall.
Honorable Mention
Jan-Lennard Struff (+150) vs. Jaime Faria
French Open Tennis Odds: Lock It In
Flavio Cobolli (-288) vs. Yibing Wu
Cobolli has climbed into the top 15 thanks to strong all-court play, but clay remains his best surface, as he is 10-5 on clay this year and 38-24 on this surface in his career. The 24-year-old Italian is a sleeper pick to make the semifinals here in a winnable section of the draw after experiencing the second week of a major by reaching the quarterfinals of Wimbledon last year. He has a 78-spot ranking edge over the 92nd-ranked Wu, who has just a 5-6 career Grand Slam main-draw record at age 26 and hadn't won a match at the French Open in his career prior to beating American Marcos Giron in the first round here.
Oleksandra Oliynykova (-233) vs. Kimberly Birrell
Oliynykova has quietly climbed up to a career-best 65th in the rankings thanks to some strong results since the Australian Open, as she reached a WTA 250 semifinal on hard courts at the Transylvania Open before putting together a solid clay-court swing that included a WTA 125 final at the Megasaray Open, a third-round result at the WTA 1000 in Rome and three match wins (including qualifying) at the WTA 500 in Strasbourg. The 25-year-old Ukrainian's playing the best tennis of her career, while the same can't be said for the 28-year-old Birrell, who came into this tournament on a four-match losing streak that lasted over two months. Birrell shocked fifth-seeded American Jessica Pegula in the first round, but that match was lost by Pegula more than it was won by the 83-ranked Aussie, as Pegula racked up 38 unforced errors, half of which came in the deciding set.
Honorable Mention
Learner Tien (-317) vs. Facundo Diaz Acosta
French Open Tennis Predictions: Value Bets
Frances Tiafoe (+128) vs. Hubert Hurkacz
Frances has found success before in France, reaching the quarterfinals here last year, and he has better clay-court results than most Americans, as Tiafoe has a career win rate over .500 on clay and has played in five ATP Tour-level finals on this surface, winning one. The big-serving Hurkacz prefers faster surfaces, and while his career numbers are strong everywhere, the former world No. 6 hasn't been the same player since undergoing knee surgery a year ago. Hurkacz has dropped to No. 99 in the rankings and is just 9-10 in 2026, while Tiafoe has a 20-10 record this year. Tiafoe has also played Hurkacz well over the years, as the 22nd-ranked American holds a 4-3 career head-to-head edge, though all seven of those meetings were on hard courts.
Adam Walton (-103) vs. Zachary Svajda
Walton is riding high after his five-set win over No. 6 seed Daniil Medvedev in the first round. Both the 97th-ranked Walton and the 85th-ranked Svajda have a chance to reach a Grand Slam third round for the first time, so this match could come down to which player holds his nerve better. The 27-year-old Walton at least has an edge in big-match experience, as he made it to the Round of 16 at last year's Miami Open and is making a 10th consecutive Grand Slam main draw appearance, while the 23-year-old Svajda is in the French Open main draw for the first time and hasn't been past the second round of a Grand Slam or Masters 1000 event in his career.
Honorable Mention
Yulia Putintseva (+121) vs. Camila Osorio
