Carlos Alcaraz vs Casper Ruud Prediction & Picks - ATP Japan Open

Prediction published on 9/29/25, 3:18 AM  by Tyler Doty | Modified on 10/10/25 at 10:19 AM in Tennis Picks

Carlos Alcaraz will face his first real test in this ATP tournament in Tokyo in the semi-finals. The Spaniard managed his efforts well in the first three rounds to reach the last four in the Japanese capital. He cruised past Argentina's Sebastian Baez, Belgium's Zizou Bergs, and America's Brandon Nakashima without dropping a single set. The world number one is on a roll, having conceded an average of just over six games to his opponents. But on Monday, Carlos Alcaraz will face a tougher challenge on paper in the form of Casper Ruud.

Casper Ruud's ambition is to regain his place in the top 10 by the end of the year. His mission for the moment is on schedule, as he will be playing for a place in the final in Tokyo on Monday. The world number 12 has gradually gained momentum as the tournament has progressed, despite a difficult start against Japan's Shintaro Mochizuki, whom he defeated in three sets. Since then, the Scandinavian has played his best tennis to dominate Italy's Matteo Berrettini and Australia's Aleksandar Vukic. Confident and in good form after a strong week of tennis, Casper Ruud now wants to try to unsettle Carlos Alcaraz on Monday, as he did at the Masters a year ago!
