Key Prediction Insights

At the 2026 US Open in New York, the hard court semifinal will feature Frances Tiafoe against Ben Shelton. The model prefers Ben Shelton to win with a 64.0% probability versus 36.0% for Tiafoe, and forecasts about 36.9 total games in the match.

Match Analysis

The model’s edge for Ben Shelton comes mainly from the serve and return game and overall strength. Serve and return is the largest single driver, contributing 8.3 percentage points toward Shelton, and overall strength adds another 3.5 points in his favor. That aligns with Shelton’s higher Elo at 2096.8 compared with Tiafoe’s 2025.5, and his marginally better surface strength index on hard courts (58.18 versus 54.62). Age and recent record at this level also nudge the projection toward Shelton. Tiafoe brings a slightly higher form index at 87.12 against Shelton’s 85.07, which explains the 3.4 percentage point tilt toward Tiafoe for recent form. Both players show identical cumulative tournament fatigue at 870 minutes on court. Their serve metrics are very similar, with mean serve indices of 96.35 for Tiafoe and 96.97 for Shelton, so no major serve gap is flagged by the >5 point rule. Tiafoe’s mean return index is 90.03, above Shelton’s 85.88, but the return gap is under 5 points. Both men arrive on confident streaks. Tiafoe has won her last three matches, including a straight sets win over Medvedev and a five setter in the last round. Shelton has also won three straight, notably beating Alcaraz in five and handling Tsitsipas in straight sets.
