Day 9 US Open best bets: Andrey Rublev moneyline as a standalone and a value-driven parlay combining Rublev and Jannik Sinner to maximize return.
The 2025 US Open has reached the business end of the tournament, and Day 9 delivers some of the most compelling matches yet. Two elite players, Andrey Rublev and Jannik Sinner, headline today’s betting card with favorable matchups supported by form, head-to-head history, and momentum.
While Rublev’s moneyline offers standalone value against Félix Auger-Aliassime, the sharper angle is pairing Rublev with world No. 1 Jannik Sinner in a moneyline parlay. This combination turns Sinner’s steep -440 line into a profit-driving anchor, while still leaning on Rublev’s consistent edge. Let’s break down both approaches.

US Open Day 9 Men’s Best Bets
Play 1: Rublev Moneyline (–125 vs. Auger-Aliassime)
-
Rublev is seeking his 10th career Grand Slam quarterfinal, a testament to his consistency at majors.
-
His head-to-head dominance over FAA is emphatic: 7–1 record, including two wins in 2025 alone.
-
Auger-Aliassime has shown flashes, but his inconsistency and Rublev’s baseline power give the Russian a significant edge.
-
At –125, Rublev’s ML is a fair standalone bet for bettors not wanting to combine legs.
Play 2: Rublev + Sinner Moneyline Parlay (+130)
-
Jannik Sinner (–440 ML vs. Bublik): World No. 1 has been nearly untouchable this season, and while the juice is heavy, he remains the most reliable anchor on the board.
-
Rublev (–125 ML vs. FAA): Complements Sinner with better odds and a favorable matchup.
-
Combining the two lifts the payout into plus-money territory (+130), which is far more appealing than betting Sinner’s heavy line alone.
-
This parlay aligns well with expected outcomes: a Sinner routine win and Rublev’s head-to-head superiority.
| Play | Odds | Why It Works |
|---|---|---|
| Andrey Rublev ML vs. FAA | –125 | 7–1 H2H dominance; chasing 10th Slam QF; reliable baseline strength. |
| Rublev ML + Jannik Sinner ML (Parlay) | +130 | Sinner as safe anchor; Rublev adds value; combo turns chalk into profit. |
Jannik Sinner wins the POINT OF TOURNAMENT against Denis Shapovalov at U.S. Open.

Day 9 of the US Open betting slate provides clean, high-confidence opportunities. Rublev ML (–125) is a justified straight bet built on dominance and form.
For added value, the Rublev + Sinner moneyline parlay (+130) transforms Sinner’s heavy juice into a plus-money opportunity while maintaining confidence in both outcomes. Together, these plays strike the perfect balance between safety and return, making them ideal for bettors looking to build profits during the critical late stages in New York.
