US Open: Osaka vs Rybakina Odds, Picks & Live Streaming
This is a fourth-round match in name only. Two-time US Open champion Naomi Osaka meets reigning Australian Open champion Elena Rybakina on Monday, September 7, 2026. It is a heavyweight collision between two of the cleanest ball-strikers in women’s tennis—and a rematch of their three-set Toronto thriller less than a month ago.
Rybakina enters without dropping a set. Osaka has survived two straight three-set battles and is managing an Achilles issue. Yet New York remains the stage where Osaka’s serve, nerve and first-strike tennis have traditionally reached another level.

Expert Picks: Naomi Osaka vs Elena Rybakina
🥇 Best Bet: Over 23.5 Total Games
The market is close for good reason. Their only meeting lasted three sets and 30 games, while all three of Osaka’s New York matches have cleared this number. Rybakina’s serve should protect her from a rout, but Osaka’s return and major-match poise make two tight sets—and possibly a third—the stronger script.

Pick 2: Naomi Osaka +1.5 Sets
Osaka took the opener in Toronto and led 4-2 in the second before Rybakina escaped. Back at her best Grand Slam venue, Osaka has enough first-strike power to split the opening two sets. The Achilles concern adds risk, but winning one set is far more forgiving than backing her outright.
Pick 3: Elena Rybakina Moneyline
Rybakina is fresher, has won six consecutive sets and already solved this matchup in Toronto. Her serve provides the cleanest pressure-point weapon, while Osaka enters after consecutive three-setters and Achilles treatment. At a playable favorite price, Rybakina is the stronger side if this develops into another physical decider.
Pick 4: First Set Over 9.5 Games
Neither player should receive many early opportunities against the other’s first serve. Their Toronto opener reached ten games despite Rybakina dropping serve immediately. Osaka has already played two tiebreaks in New York, while Rybakina needed one against Starodubtseva. One break—or none—could be enough to cash this total.

Final Prediction: Will Rybakina Survive Another Osaka Test?
This should look nothing like Rybakina’s first three matches. Osaka can match her power, punish second serves and create pressure with the flat backhand. She also knows she was only a handful of points from winning their Toronto encounter. New York’s energy should help her produce at least one elite stretch.
Rybakina still owns the stronger full-match position. She is fresher, serving more consistently and less dependent on managing a physical issue. If the match reaches a deciding set, her ability to generate inexpensive service points should matter more with every game. Expect Osaka to strike first before Rybakina gradually takes control of the biggest moments.
