The ATP Masters 1000 Madrid second round on April 25 features a mix of rising talents and established names. Vilius Gaubas’ strong run makes him a live underdog to keep things close, Alexander Blockx’s form gives him an edge in a balanced matchup. At the same time, Alexander Zverev’s experience and quality should see him through comfortably.
ATP Masters 1000 Madrid 1/32-Finals
Gaubas – Auger-Aliassime: 25.04.2026 14:00 CEST
H2H: first meeting
Vilius Gaubas has won three of his last five matches. This week in Madrid, Gaubas qualified for the main draw tournament. In the opening main draw round, Gaubas upset Baez in straight sets. He offered and saved two breakpoints.
Felix Auger-Aliassime has won four of his last five matches. The last match he played was in Monte Carlo, where he lost to Sinner in the quarterfinals in straight sets.
Best Bet to Make
According to the bookies, Gaubas is the underdog in this matchup, but we disagree. He dominated so far this week in Madrid. If he serves well, we expect him to keep this match close.
That being said, Gaubas covering the games handicap is a value bet.
Value bet/ the best odds: Vilius Gaubas +3.5 games handicap @2.10 @bet365
Nakashima – Blockx: 25.04.2026 14:00 CEST
H2H: 2-0
Brandon Nakashima has lost three of his last five matches. Last week in Barcelona, Nakashima lost to Fils in the second round in straight sets.
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.
Best Bet to Make
According to the bookies, this will be an almost 50-50 matchup, but we disagree. Blockx is in great form and enjoys playing on clay. He is a better clay-court player, and we expect him to dominate the rallies.
That being said, Blockx winning is a value bet.
Value bet/ the best odds: Alexander Blockx winning @1.73 @bet365
Navone – Zverev: 25.04.2026 16:00 CEST
H2H: first meeting
Mariano Navone has won four of his last five matches. Last week in Barcelona, Navone lost to Rublev in the opening round in straight sets. This week in Madrid, the Argentine defeated Borges in straight sets. He has never made it past the second round here.
Alexander Zverev has won three of his last five matches. Last week in Munich, the German lost to Cobolli in the semifinals in straight sets. He was the champion here in 2018 and 2021. Last season, Zverev lost to Cerundolo in the fourth round in straight sets.
Best Bet to Make
According to the bookies, Zverev is the favourite in this matchup, and we agree. He enjoys playing in Madrid and is in solid form. Navone has no weapons. We expect the German to dominate on his serve and backhand.
That being said, Zverev winning in straight sets is a value bet.
Value bet/ the best odds: Alexander Zverev winning 2-0 @1.73 @bet365
