Casper Ruud vs Aleksandar Vukic prediction
Ruud has a 58 percent win rate on hard courts, with the Norwegian reaching seven finals on the surface, with his only title being at the San Diego Open in 2021, and his last hard-court final being at Dallas this year.
Vukic has not won any title on the ATP Tour, but his only final came on a hard court at the 2023 Atlanta Open, where he lost 5-7, 7-6 (5), 4-6 against Taylor Fritz, alongside which the Australian has also reached eight hard-court finals on the Challenger Tour, winning two titles on the surface.
Even though Vukic has won the only match he has played against Ruud, the Norwegian is the favorite for the upcoming match as he is the higher-seeded and ranked player.
Pick- Ruud to win in straight sets
