Published:
- Arthur Gea’s moneyline (+144) offers better value to pull off the upset in the US Open Round of 16
- Take the Over on 38.5 games (+100) in a matchup with strong five-set potential
- Gea’s return profile, pressure-point edge, and hard-court Elo make the underdog more than a rankings-based fade
On September 7 at 2:30 p.m. ET, Arthur Gea and Botic Van de Zandschulp will face off at the Grandstand in the Round of 16 of the US Open, which marks their first meeting on the ATP Tour.
World No. 70 Van de Zandschulp enters as the analytical favorite against the 87th-ranked underdog, Gea. The single most important matchup question for bettors is whether Gea’s aggressive returning can consistently pressure Van de Zandschulp’s second serve. If it can, the Frenchman has enough recent hard-court form and five-set resilience to turn the market’s ranking gap into an upset.
Gea vs Van De Zandschulp Picks
The outright price makes Gea the value side, even though Van de Zandschulp is the nominal favorite.
Moneyline Prediction: Arthur Gea (+156 at Polymarket)
Tennis Abstract’s Aug. 31 Elo snapshot has only 26 points between them overall—Van de Zandschulp at 1,772.7 and Gea at 1,746.4—while Gea holds the better hard-court Elo, 1,759.9 to 1,743.9. That is a much narrower gap than the market’s moneyline implies.
The 52-week Tennis Ratio comparison reinforces the surface-specific case: Gea wins 28.8% of return games to Van de Zandschulp’s 21.3%, converts 43.9% of break points to 41.0%, and wins 51.0% of return points against the Dutchman’s 49.7%. Gea also owns the stronger dominance ratio (1.203 to 1.041), breakpoints-prevail ratio (1.503 to 1.131), and match-efficiency mark (2.058 to 0.960). Van de Zandschulp has small serving advantages, including a 74.2% first-serve-points-won rate and 81.1% service-games-won rate, but Gea’s return pressure is the more decisive matchup edge.
That profile has already translated to the tournament. Gea has beaten Juan Manuel Cerundolo, Zachary Svajda, and Michael Zheng in New York, while Van de Zandschulp has needed three-set or five-set battles against Jesper de Jong, Alex de Minaur, and Zizou Bergs. Gea’s 65.8% pressure points won on serve and 41.4% on return also compare favorably with Van de Zandschulp’s 64.9% and 35.5%. At +144, back Gea to continue the run.
Game-Total Prediction: Over 38.5 Games (+100 at Kalshi)
The Over pairs naturally with the underdog moneyline. Both players have held 81% of service games over the comparison period, so neither is likely to run away through routine service breaks. At the same time, Gea’s superior return game and break-point numbers should create enough pressure to produce competitive sets rather than a procession of comfortable holds.
Their recent hard-court paths also point toward length: Gea has won three consecutive US Open main-draw matches, all requiring meaningful scoreboard pressure, while Van de Zandschulp has just come through a five-setter with Bergs and a four-setter against de Minaur. The best-of-five format gives the Over multiple routes to cash, including a four-set match with two tight sets or a full five-set contest.

Botic Van de Zandschulp enters the match as the betting favorite, with his moneyline payout reflecting a distinct mathematical advantage in the matchup. Arthur Gea is positioned as the underdog, receiving a 3.5-game cushion on the spread.
The total games line indicates the market expects a highly competitive contest to unfold on the Grandstand. I am bypassing standard sportsbook pricing to utilize Kalshi’s premium payouts for these specific markets, which offer a significantly better return on investment for the discerning bettor.
