Alex de Minaur vs. Christopher O’Connell Preview, Prediction and Betting Odds for US Open 2025 Round-1

First meeting between the Aussie duo.

Aug 5, 2025; Toronto, ON, Canada; Alex de Minaur (AUS) returns a ball to Ben Shelton (not pictured) during quarterfinals at Sobeys Stadium.

World No. 8 Alex de Minaur begins his 2025 US Open campaign with a Round-1 encounter against countryman Christopher O’Connell on Tuesday. The latter has already notched some impressive wins over top players, and will be on the prowl for another upset victory. However, de Minaur is a two-time quarterfinalist in New York and no walkover on a hard court. Who will emerge victorious? Let’s take a look at the stats and records, as well as the BetMGM odds.

Alex de Minaur vs Christopher O’Connell Match Preview

Alex de Minaur is among the most consistent players on the ATP Tour. The 26-year-old has a solitary title to his name in 2025, but ended up in the deeper stages of competitions on multiple occasions. Yet to break into the Top-5, this year’s US Open presents countless opportunities for the Australian. Alex de Minaur won the title in Washington DC last month; his other performances that gained him plaudits came at Rotterdam (final) and Monte Carlo (semis). With a service game success rate of 80% on hard courts, de Minaur is a firm favourite in this Round of 128 battle.

THREE CHAMPIONSHIP POINTS SAVED AND DE MINAUR TAKES THE TROPHY 🏆

Christopher O’Connell comes into this match with a tour-level record of 10-17 this year, and a hard court record of 13-9 in all competitions. Having reached the pre-quarterfinals of both Middle Eastern events, O’Connell struggled throughout the clay court swing. Despite going back to the drawing board, the 31-year-old did not manage to impress since then. After earning an outstanding win over Stefanos Tsitsipas in Toronto, a withdrawal meant that fans were denied a maiden de Minaur vs O’Connell battle.
