Casper Ruud defeated Matteo Berrettini 7–6, 6–2 in the second round of the ATP 250 Tokyo tournament on hard court, confirming his status as pre-match favourite with odds of 1.71 to Berrettini's 2.27. The Norwegian secured a tight opening set via tiebreak before taking control in the second, where he broke serve twice to close out the match comfortably. Ruud's composed performance, particularly his conversion of set-point opportunities in the first set and his dominance thereafter, underlined his superior ranking and recent form on the hard court. The victory advances him to the quarter-finals and maintains his momentum in the Asian swing.
