Key Prediction Insights

At the 2026 US Open in New York, Marcos Giron and Ignacio Buse meet in the Round of 128 on outdoor hard courts at a grand slam. The model favors Ignacio Buse, with a 78.28% chance of victory versus 21.72% for Marcos Giron. The match is expected to be relatively compact, with a predicted total of about 37.3 games.

Match Analysis

The model’s edge for Buse comes mainly from recent form, and to a smaller extent from age and marginal advantages in serve and return and overall strength. Recent results underline that view. Buse arrives with three straight wins at Winston Salem, beating Arthur Fery, Benjamin Bonzi and Juan Manuel Cerundolo. Giron has struggled in his last three hard court outings, losing to Dhakshineswar Suresh, Henrique Rocha and Hubert Hurkacz. That recent form swing accounts for the largest single driver of the prediction. Looking at the numbers, Buse is the higher-ranked player at 36 versus Giron at 77, and Buse’s Elo rating sits noticeably above Giron’s (1711.14 to 1546.42). Form indexes also favor Buse, 48.61 to Giron’s 32.83. Surface strength index gives Buse an edge as well, 24.66 compared with Giron’s 12.29. Both players show similar serve and return profiles on paper, with mean serve indices around the mid 90s and mean return indices around 88 to 89, so neither has a stark serving advantage based on those metrics. Fatigue is not a factor for either player, with zero cumulative minutes on court in this event.
