US Open: Michelsen vs Etcheverry Odds, Picks & How to Watch
This is the kind of fourth-round opportunity players spend careers waiting for. On Sunday, September 6, unseeded American Alex Michelsen meets No. 27 seed Tomás Martín Etcheverry with a first US Open quarterfinal on the line. Michelsen is ranked 14 places below the Argentine, but the betting market has installed him as a commanding favorite.
That price reflects the surface. Michelsen has swept all nine sets in New York, owns the better natural hard-court game, and already eliminated No. 16 seed Brandon Nakashima. Etcheverry has dropped only one set himself, however, and brings enough serve and forehand weight to prevent this from becoming another routine American victory.

Expert Picks: Alex Michelsen vs Tomás Martín Etcheverry
🥇 Best Bet: Over 3.5 Sets
Michelsen has not surrendered a set, but Etcheverry presents a different serving challenge. The Argentine won 76% of his first-serve points and 68% behind his second serve against Navone. Michelsen should eventually separate on hard courts, but Etcheverry’s delivery and forehand give him a credible route to one set.

Pick 2: Alex Michelsen -1.5 Sets
The American has controlled this tournament without spending unnecessary energy. He has won nine consecutive sets, dropped serve just once against Mérida, and already handled Nakashima in straight sets. Etcheverry can make the match longer, but beating Michelsen twice across four or five sets looks like a much tougher assignment.
Pick 3: Alex Michelsen to Win 3-1 (+260)
This offers a more attractive return than laying -285 on the moneyline. Etcheverry has held in 14 of 15 service games against Navone and carries enough first-strike power to steal a close set. Michelsen’s return positioning, backhand stability, and comfort changing direction should decide the other three.
Pick 4: Alex Michelsen Moneyline (-285)
The price is steep, so this works better as a parlay piece than a large straight wager. Michelsen owns the cleaner hard-court profile and has defeated the stronger opposition in New York. If the match becomes physical, the 22-year-old American should also have more available late in the afternoon.
Why Is No. 46 Michelsen Such a Heavy Favorite?
- The rankings say Etcheverry should be closer to even money. The matchup says otherwise. A -285 line gives Michelsen an implied win probability of approximately 74%—matching one prominent match projection. That means the market is treating the American’s current ranking as less important than the surface and his recent performance.
- Michelsen’s victory over Nakashima is particularly persuasive. He beat the No. 16 seed 6-3, 6-4, 6-4, then followed it by controlling Mérida 7-6(5), 6-4, 6-3.
- Etcheverry’s run has been excellent, but his biggest 2026 achievement- winning his first ATP title in Rio—came on clay. The faster New York hard courts place greater pressure on his movement, return position, and ability to defend Michelsen’s early backhand strikes.
- The moneyline appears correctly priced. Bettors searching for greater upside may find more appeal in Michelsen 3-1 or the sets handicap.

Final Prediction: Will Michelsen Reach His First Major Quarterfinal?
Etcheverry is too accomplished and serving too effectively to dismiss. If he lands first serves, controls the middle with his forehand, and protects his backhand corner, he can make Michelsen work well beyond the two-hour mark.
The American still owns more ways to win this matchup. Michelsen can return from multiple positions, take the backhand early, and move forward when Etcheverry gets stretched. His second-serve performance has also been strong enough to prevent opponents from attacking freely.
Expect one tight set to swing toward Etcheverry, possibly through a tiebreak. Over the full match, Michelsen’s cleaner hard-court movement and ability to take time away should create the decisive separation.
