Adrian Mannarino Player Overview
Adrian Mannarino find themselves in a tough spot, having managed just one win in their last ten matches-a clear sign of ongoing struggles with form. Recent defeats to Dzumhur, Collignon, and Humbert further underline these issues. Over this stretch, Mannarino has claimed only 42% of games played and has managed to win just a quarter of all sets contested. On serve, Mannarino wins 77% of their service games-a figure thatβs about average for the ATP level. However, a high percentage of points lost on second serve and a significant number of double faults from opponents (with Mannarino conceding an average of 7.7 aces per match) have hindered their ability to stay competitive on the scoreboard. All these factors make it increasingly difficult for Mannarino to keep pace with their rivals.

Expected scenario

Total Games Prediction
Mannarino consistently falls short of the 12.5-game mark, even when facing mid-tier opponents-a clear indication of his current struggles on court. This trend supports a bet on the Frenchman staying under the projected games total.
β Editorial Prediction
Adrian Mannarinoβs recent struggles contrast with Dialloβs consistent ability to limit opponentsβ game totals, even when his own results fluctuate. Given the Frenchmanβs low set-winning percentage, itβs unlikely heβll surpass the proposed individual games line at this moment. A quick two-set match seems the most probable scenario, making this market the optimal choice for this clash. The pick - Adrian Mannarino under 12.5 games (individual total).
