Adolfo Daniel Vallejo will try to end Gael Monfils’ Grand Slam career on Tuesday in the first round of the 2026 US Open.
Caesars Sportsbook set +160 odds on Vallejo to win and for both players to win a set combo.
Current Form:
Gael Monfils enters his final US Open run with a 1-2 record in the warm-up tournaments. The electric Frenchman reached the second round of the 2026 Montreal Masters and lost in the first round of the 2026 Cincinnati Open.
Adolfo Daniel Vallejo crashed out in the first round in Montreal but posted back-to-back wins over Kyrian Jacquet and Valentin Vacherot to reach the third round in Cincinnati before bowing to Tommy Paul. Vallejo also earned a win over Pablo Carreno Busta before he succumbed to Botic Van De Zandschulp in the second round of the 2026 Winston-Salem Open.
The Matchup: Vallejo and Monfils will play against each other for the first time on tour or Grand Slam event.
