Reilly Opelka continued his sweep into the Western & Southern Open quarter-finals — his first at ATP Masters 1000 level — on Tuesday with a brisk 75-minute victory.
Opelka recorded just the fifth Top 10 win of his career with a 6-3, 7-6(4) triumph over sixth seed Matteo Berrettini. He now challenges fourth seed Stefanos Tsitsipas or 2013 finalist John Isner.
Opelka struck 29 winners, including 19 aces, and forced Berrettini into a forehand error for the only break of the match in the eighth game. The American won 33 of his 35 first-service points, committed 12 unforced errors and clinched 51 points under three shots to Berrettini’s 38.
Overall this week in New York, Opelka has struck 50 aces, including 18 against Cameron Norrie in the first round and 13 against Diego Schwartzman in the second round.
The 22-year-old is now 10-3 on the season, suspended for five months due to the global COVID-19 pandemic. He lifted his second ATP Tour title in February at the Delray Beach Open by VITACOST.com.
