Carlos Alcaraz vs Casper Ruud Prediction: Alcaraz favoured — will Ruud spring a shock?

Carlos Alcaraz vs Casper Ruud Prediction, Odds, and Betting Tips | Japan Open 2025

The semi-final of the Kinoshita Group / Japan Open (ATP 500) will be held in Tokyo’s Ariake Coliseum between World No. 1 Carlos Alcaraz and Norway’s Casper Ruud – a vital late-season ATP 500 battle that could have both ranking and confidence effects before the Asian tour. After winning at the US Open, Alcaraz is expected to bring his best form to the tournament; on the other hand, Ruud has been steady and threatening on his hard court game during this swing. The bettors who are interested in the best odds should track the pace of the game, early breaks, and the live market for value.

🇪🇸 Carlos Alcaraz

Carlos Alcaraz is the tournament favourite: he still holds the world No.1 spot and a few days ago won the 2025 US Open, which gives him an incredible form going to Tokyo. Furthermore, he has made it possible for him to win a lot of matches this season (he even equalled his personal best of the number of victories for a season with 65 wins in 2025 in Tokyo) and has been very impressive in his last few matches.Aside from that, Alcaraz had a foot/ankle incident... the medical staff was called quite early during the Baez interaction but he retrieved his power to move on and beat Brandon Nakashima 6-2, 6-4 to reach the semis — delivering a mix of heavy forehand winners, perfect movement, and aggressive net play. On hard courts he is one of the most skillful players as he can combine the speed and angle of his aggression with the serve that has been getting better lately; that is why when his footwork and forehand come together he gives so little room to the opponent to strike a mistake, however if he is a bit rusty at the beginning of the match or if he feels tightness after the injury scare then he could possibly lose a set. 

🇳🇴 Casper Ruud

Casper Ruud reached Tokyo as the No.4 seed and has been very solid throughout the draw to the semifinals, where he defeated Aleksandar Vukic 6-3, 6-2. Ruud's tennis is a combination of perfectly and consistently hitting the ball, patiently playing through the points, and being at the top of his defensive positioning; basically, he applies pressure on opponents by prolonging rallies and forcing them to make mistakes. Once only a clay-court specialist, Ruud has progressively improved his hard-court results and shown the ability to break serve when given the opportunity and also to end long rallies if he wants. Additionally, he has a big win over Alcaraz at the 2024 Nitto ATP Finals (a straight-sets upset), which testifies to him being able to give a high-level performance on indoor/hard surfaces, and in important moments. I would guess that Ruud will probably be trying to keep the rallies going, weakening Alcaraz's forehand with depth and waiting for a quick ball opportunity.
