The remaining ATP Masters 1000 Madrid Round of 16 matches on April 27 feature a mix of solid favourites and in-form challengers. Francisco Cerundolo and Felix Auger-Aliassime look well-positioned to control their matches. At the same time, Adolfo Daniel Vallejo’s impressive run in Madrid could help him push Flavio Cobolli in a competitive encounter.
ATP Masters 1000 Madrid 1/16-Finals
Cerundolo – Darderi: 27.04.2026 15:00 CEST
H2H: 3-2
Francisco Cerundolo has won three of his last five matches. This week in Madrid, the Argentine defeated Hanfmann in the opening match in straight sets.
Luciano Darderi has lost three of his last five matches. Last week in Munich, Darderi lost in the second round against Kopriva in three sets. This week in Madrid, the Italian defeated J.M. Cerundolo in straight sets. He dominated from start to finish.
Best Bet to Make
According to the bookies, Cerundolo is the favourite in this matchup, and we agree. Earlier this season in Buenos Aires, Cerundolo demolished Darderi in straight sets. He enjoys playing on fast clay courts. We expect him to win.
That being said, Cerundolo winning is a value bet.
Value bet/ the best odds: Francisco Cerundolo winning @1.50 @bet365
Blockx – Auger-Aliassime: 27.04.2026 16:30 CEST
H2H: first meeting
Alexander Blockx has won three of his last five matches. Last week in Munich, Blockx lost to Shelton in the second round in straight sets. This is his debut campaign in Madrid. In the opening round, the Belgian defeated Garin in three tight sets, after losing the opening set 4-6. In the second round, Blockx turned the match around against Nakashima, winning in three sets.
Felix Auger-Aliassime has won four of his last five matches. This week in Madrid, the Canadian defeated Gaubas in the opening match in straight sets. He offered no breakpoints.
Best Bet to Make
According to the bookies, Auger-Aliassime is the favourite in this matchup, and we agree. Blockx looked tired against Nakashima and will struggle. On the other hand, the Canadian served well and dominated. We expect Auger-Aliassime to win comfortably.
That being said, Auger-Aliassime covering the games handicap is a value bet.
Value bet/ the best odds: Felix Auger-Aliassime -2.5 games handicap @1.73 @bet365
Vallejo – Cobolli: 27.04.2026 18:00 CEST
H2H: first meeting
Adolfo Daniel Vallejo has won three of his last five matches. This week in Madrid, Vallejo qualified for the main draw tournament. He upset Dimitrov and Tien in the opening rounds, winning both matches in straight sets.
Flavio Cobolli has won four of his last five matches. This week in Madrid, Cobolli won the opening match against Ugo Carabelli in three sets, after losing the opening set 6-7. He offered and saved two breakpoints.
Best Bet to Make
According to the bookies, Cobolli is the favourite in this matchup, but we disagree. Vallejo is in great form and played the best tennis of his life this week. We expect him to keep this match close.
That being said, Vallejo covering the games handicap is a value bet.
Value bet/ the best odds: Adolfo Daniel Vallejo +2.5 games handicap @1.83 @bet365
