Key Prediction Insights

At the 2026 US Open in New York, round of 128 on hard courts, Alexander Blockx is favored to advance over Tomas Barrios Vera. The model gives Blockx a 68.15 percent chance to win versus 31.85 percent for Barrios Vera. The match is projected to last about 38.05 games in total.

Match Analysis

The model’s edge for Blockx comes mainly from surface fit and recent form. Surface fit contributes 5.5 percentage points toward Blockx, supported by his strong mean serve index (96.74) and mean return index (88.78) on a medium paced hard court. Those figures suggest he can both hold serve and apply pressure on return games. Recent form adds another 5.2 points toward Blockx. While Barrios Vera enters with three straight wins at this event, those matches were long and have left him with 522 minutes of fatigue. Blockx has no accumulated minutes in this event and has been contesting tough hard court draws in Cincinnati and Toronto, including a win over Mariano Navone and competitive three set matches versus higher level opponents. Overall strength and rankings also favor Blockx. He sits at rank 32 with an Elo of 1772.7, versus Barrios Vera at rank 144 and an Elo of 1649.6. Those factors contribute a combined roughly 5.5 points in Blockx’s favor through overall strength, age and record considerations. Surface strength indices show Barrios Vera at 22.52 and Blockx at 14.27, but the model still leans to Blockx because his serve and return profiles translate well to hard courts. The difference between their mean serve indexes is under 5 points, and the mean return gap is also under 5 points, so neither metric is overwhelmingly lopsided. Recent match summaries: Blockx is 1-2 across his last three outings with a long 149 minute loss to Flavio Cobolli and a straight sets win over Navone. Barrios Vera is 3-0 at this event, beating Daniel Rincon and Genaro Olivieri 2-0 and winning 2-1 versus Juan Carlos Prado Angelo.
