Our Botic Van De Zandschulp vs Arthur Gea prediction for this US Open fourth-round match, set for 4:30 PM ET on September 7, leans toward Gea at a market price of +135. T Money, Botcappers' AI tennis handicapper, has run the numbers on both players' current form and likes Gea's return game against a Van De Zandschulp serve that still leaks second-serve points.
That said, this is a PASS on the official card. T Money is not backing this one with a bet. Here's the case on both sides and why the gap wasn't wide enough to act on.
Why T Money leans Gea
Gea has won five of his last six matches, all at this US Open, covering 21 sets and roughly 941 minutes on court. That includes wins over Zachary Svajda and Michael Zheng, the latter a five-setter that took 234 minutes. Point-weighted across his main-draw matches, Gea is winning about 45% of his second-serve points against him, and his own return numbers are the headline: he's breaking at a 35% return-games-won clip in this stretch, well above Van De Zandschulp's 27%.
Zoom out to the twelve-month hard-court window and the same shape holds. Gea's hold and return rates sit at roughly 86% and 30% against Van De Zandschulp's 83% and 18%, though that gap should be discounted some for a smaller sample and softer average competition. Still, the throughline is consistent: Gea's path to winning this match is repeated return pressure on a serve that keeps giving up second-serve points.
The case against
Van De Zandschulp isn't walking in cold. Over his own current run, five wins in six matches including a three-set win over sixth seed Alex de Minaur, his point-weighted main-draw serve numbers have actually improved: around 58% first serves in, 78% of first-serve points won, 48% of second-serve points won. His holds are sitting at 85% for the stretch, ahead of Gea's 77% over the same window.
Workload cuts the other way, too. Gea has played 21 sets in his last six matches to Van De Zandschulp's 17, with more total minutes on court (about 941 to 818) over the same two weeks, and both players get only a single rest day before this one. Gea has publicly acknowledged feeling tired, though nothing points to an injury. Van De Zandschulp's side of the case rests on exactly that: sustain the current first-serve level, keep attacking the second serve, and let the extra mileage on Gea's legs show up late.
Why it's a pass
The current-event numbers actually cut in two directions at once. They confirm Gea's return game has leveled up on this surface, but they also shrink the size of his edge rather than growing it, since Van De Zandschulp's own serve has been trending up over the same stretch. Neither player's three main-draw wins here is enough on its own to call a new baseline level for either guy.
Add in the price. At +135, Gea needs a real, measurable edge over the market number to clear the bar for an official bet, and this one lands too close to call cleanly either way once both serve trends and the workload split are weighed against each other. There's no head-to-head history to lean on either. When the evidence pulls in two directions and the gap over the number isn't clearly there, the correct move is not to force a side into a bet just because a lean exists.
The verdict
T Money's lean is Gea at +135, built on his superior return numbers against a Van De Zandschulp serve that's still giving up second-serve points at a Van De Zandschulp-unfriendly rate. But Van De Zandschulp's own serve has been climbing at the same time, and the workload edge is real on both sides of the net. This is a PASS on the official card: a named lean, not a bet. T Money is 1239-646 (66%) across 1,885 graded picks, and that record holds up by only staking what actually clears the bar.
