The ATP Queen’s Club opening round on June 16 features several dangerous grass-court matchups as players continue preparing for Wimbledon. Jakub Mensik returns to action after his breakthrough run to the French Open semifinals and now faces experienced left-hander Adrian Mannarino, who also arrives with confidence following a strong week in ’s-Hertogenbosch. Alex de Minaur begins his London campaign after reaching the final in the Netherlands, but Gabriel Diallo’s powerful serve could create problems on fast grass courts. Meanwhile, Marin Cilic looks to carry over his solid form from last week into a tricky clash against Ugo Humbert, with both players aiming to rediscover consistency early in the grass season.
ATP Queen’s Club 1/16-Finals
Mensik – Mannarino: 16.06.2026 12:30 CEST
H2H: first meeting
Jakub Mensik has won four of his last five matches. The last match he played was at the French Open, where he lost to Zverev in four sets in the semifinals. Last season in London, Mensik lost to Bautista Agut in the 1/8 finals.
Adrian Mannarino has won three of his last five matches. Last week in Hertogenbosch, Mannarino lost to de Minaur in straight sets in the semifinals.
Best Bet to Make
According to the bookies, Mensik is the slight favourite in this matchup, and we agree. He had a great run at the French Open and comes fully confident into this matchup. Considering his playing style, we expect him to dominate on grass.
That being said, Mensik winning is a value bet.
Value bet/ the best odds: Jakub Mensik winning @1.50 @bet365
De Minaur – Diallo: 16.06.2026 14:00 CEST
H2H: 2-0
Alex de Minaur has won three of his last five matches. Last week in Hertogenbosch, de Minaur lost to Majchrzak in the final in three sets. Last season in London, the Australian lost to Lehecka in the opening round in straight sets.
Gabriel Diallo has lost four of his last five matches. Last week in Hertogenbosch, the Canadian lost to Mannarino in the opening round in three sets. Last season in London, Diallo lost to Lehecka in the second round in straight sets.
Best Bet to Make
According to the bookies, Diallo is the heavy underdog in this matchup, but we disagree. He enjoys playing on grass and pushed de Minaur to three sets in Paris last season. If he serves well, we expect him to keep this match tight.
That being said, Diallo covering the games handicap is a value bet.
Value bet/ the best odds: Gabriel Diallo +3.5 games handicap @2.25 @bet365
Humbert – Cilic: 16.06.2026 17:00 CEST
H2H: 1-0
Ugo Humbert has lost three of his last five matches. Last week in Hertogenbosch, the Frenchman lost to Bonzi in the second round in three sets. His last appearance here was in 2024, where he lost to Arnaldi in the opening round.
Marin Cilic has lost three of his last five matches. Last week in Hertogenbosch, Cilic lost to Medvedev in the quarterfinals in three sets. His last appearance here was in 2022, when he lost to Krajinovic in the semifinals in straight sets.
Best Bet to Make
According to the bookies, this will be an almost 50-50 matchup, but we disagree. Cilic had a solid run last week in Hertogenbosch. He enjoys playing on grass, especially in London. If he serves well, we expect him to be a better player.
That being said, Cilic winning is a value bet.
Value bet/ the best odds: Marin Cilic winning @2.10 @bet365
