2026 French Open men's semifinal predictions

Onorato has analyzed both men's semifinal matches. One bet he is targeting is Over 37.5 games in Cobolli vs. Arnaldi: "The fatigue angle is real but it cuts both ways for the totals," Onorato said. "Arnaldi plays long matches not because he wants to, but because his game invites them. He grinds, he scraps, he resets, and his opponents have consistently needed four and five sets to get past him. Cobolli is a different profile but not a blowout artist either. He plays physical, athletic clay-court tennis and has been tested in multiple matches at this tournament. Two Italians who know each other's games, competing on the biggest stage of their careers, with a Grand Slam final on the line. This match does not stay short."  See the rest of Onorato's picks here .
