Our Ignacio Buse vs Marcos Giron prediction for this September 2 first rounder at the US Open (12:30 PM ET start) starts with the obvious headline: Buse is red hot. He walked out of Winston-Salem last week with a title, a career high ranking, and a five match run that included a win over the exact player who beat him on hard courts less than two weeks earlier. Giron, by contrast, has one result on the board since late August, and it is a loss.
T Money's fundamentals read likes Buse here. That is not the same as a bet. The card marks this one PASS, meaning no side cleared the bar to become an official stake, so there is no play going out backing Buse at -110 today.
Why the form favors Buse
Buse did not just win Winston-Salem, he won it by dismantling the field. He opened by beating Adam Walton, the same player who had beaten him 6-4, 6-3 on hard courts eleven days earlier, then rolled through Daniel Altmaier, Juan Manuel Cerundolo, and Benjamin Bonzi before closing out Arthur Fery in the final in just 77 minutes. That run is the youngest title in the tournament's history and Buse's second title of the season. It is also fresh, same surface evidence, not a career line padded with results from years ago. His hard court form over the last twelve months sits at 8-5, and five of those eight wins came in the last two weeks with real return pressure behind them, not gifted break points.
Giron's most recent hard court match is a first round loss at that same Winston-Salem event, to a lucky loser ranked outside the top 350. His own serve held up fine in that match, but he could not find anything on return, and it fits a longer pattern: he has dropped three straight hard court matches going back to late July, with a gap in his schedule in between. His hard court form over the last twelve months has faded to 43 percent, down sharply from a stronger start to the year.
The stylistic matchup and the one head to head note
Giron's game plan is built around holding cheaply and grinding down a server who does not blow people off the court. That is a real threat to Buse, whose delivery numbers sit around 61 percent on first serve and 50 percent on second serve, the kind of number a compact counterpuncher can chip away at over a long match. It is worth naming because it is the actual mechanism behind any Giron upset in this match, not just an opponent being talented.
The two have met once, on grass back in June, and Buse won a three setter. That result is worth mentioning only as a secondary data point. Grass rewards Giron's flatter, quicker game far more than a hard court would, and it is a different surface than the one they play on this week, so it does not carry the prediction here one way or the other.
The risk and why this stays a PASS
The number Buse has to answer for is his own workload. Five matches and roughly 603 minutes on court in two weeks, capped by a final that went the distance in the middle rounds, is a real physical bill, and he is coming into this match on four days' rest. If this one stretches into a fourth set, that workload is the thing to watch, not Giron's ranking.
Even with that said, the fundamentals case here favors Buse. But T Money's execution rules are separate from the read on the match, and this one lands as a PASS on the official card at -110. That means Buse is not a named play today. It is a side we like on paper without a bet attached to it, and the difference matters.
The verdict
Ignacio Buse enters this US Open first rounder off a title run that upgraded his hard court form in a real, measurable way, and Marcos Giron enters it off a loss that confirmed a five month slide on the same surface. That gap is genuine. It just does not translate into an official bet here. This one is PASS, not a play, at -110 on Buse.
