In an impressive maids duel, third-seeded American Riley Opelka defeated compatriot John Isner, the fourth seed, on Sunday to claim the ATP title on clay in Houston.
In one hour and 49 minutes, Opelka finished his opponent 6-3, 7-6 (9/7).
Opelka hits 10 aces per serve, more than his opponent by 2. Both players are among the most effective in the round with their serve.
This is the first time that two Americans have met in the ATP Final in Houston since 2018.
Opelka, who stopped controversial Australian Nick Kyrgios in the run-up, reached the Houston final for the first time in five attempts.
The former US top seed performer, who sustained an injury at the Miami Open a few days ago, was very fortunate to win that tournament now.
Riley continues to dominate the personal hat against his countryman now 5-1.
Isner had just eliminated Chilean Christian Garin in the semi-finals in a close match 4-6 6-3 6-4.
This was his third final in Houston. In 2013 he beat the Spaniard Nicolas Almagro, while in 2012 he lost to the Argentine Juan Monaco.
Sunday’s result at the Houston Tennis Championships:
Riley Opelka (USA/No.3) beat John Isner (USA/No.4) 6-3, 7-6 (9/7).
