Felix Auger-Aliassime vs Billy Harris Preview, Predictions and Betting Odds for 2025 US Open Round 1

Felix Auger-Aliassime gets ready to start his US Open journey with a matchup with Billy Harris

World No. 27 Felix Auger-Aliassime will be battling it out with the lucky loser Billy Harris in Round 1 of the 2025 US Open. To say that Alisassime has had a topsy-turvy 2025 wouldn’t be an understatement. The 25-year-old had an explosive start to his 2025 campaign as he won titles in Adelaide and Montpellier. Aliassime followed that up with another hard-court final in Dubai. However, he hasn’t been able to recreate similar momentum in the North American swing till now.

Billy Harris hasn’t had a particularly impressive year. Harris has mostly spent his time playing the Challenger series. However, a small highlight for him came in the New Delhi Challenger, where he finished as the runner-up. During the qualifiers, Harris was defeated by Coleman Wang but made it to the US Open as the lucky loser. Let’s dive deep into this matchup and predict the winner using the most accurate betting odds provided by BetMGM.

Billy Harris will make his @usopen main draw debut 🙌

Felix Auger-Aliassime vs Billy Harris Match Prediction

Aliassime has won all 7 of his titles on the hard court. However, only one of those titles came in the outdoor hard court. At the same time, Aliassime has also been in 13 hard-court finals in his career. Compared to this, Billy Harris hasn’t played any hard-court finals on the ATP Tours. Yes, Harris has won a few ITF World Tennis Tournament titles but Harris still lacks experience. As a result, Aliassime looks like an easy winner of this contest.
