Reilly Opelka vs Hugo Dellien prediction

Opelka has been pushing himself to register a strong result. The American missed out at Wimbledon but was two wins away from clinching the title in Rosmalen. His fiery serve and towering presence have always caused problems for his opponents.

Dellien, on the contrary, has yet to find consistency on the main tour. The Bolivian has made a name for himself at the Challenger circuit, but lacks the artillery to compete against established opponents at the highest level. He has a decent all-around game and likes to play a defensive brand of tennis.

Considering their record on tour and results this year, Opelka will be a clear favorite to win. The American should be able to stamp his authority and power through to the second round in Cincinnati.

Pick: Opelka to win in straight sets.
