Reilly Opelka put on a serving masterclass in last year’s New York Open, firing 156 aces throughout the week to secure his maiden ATP Tour title. The third-seeded American appears primed for another big serving display this year, landing 20 aces on Thursday to defeat Yoshihito Nishioka 6-4, 6-4.

The 22-year-old grabbed the lone break in each set to reach the quarter-finals after 76 minutes. Opelka picked up his first win of the season after suffering tight first-round defeats in Adelaide and the Australian Open.

Next up for the defending champion is qualifier Jason Jung, who continued his inspired tennis at this event to upset seventh-seeded Brit Cameron Norrie 6-4, 6-4. Both of Jung’s ATP Tour quarter-finals, and four of his six ATP Tour main draw wins, have come in New York.

The 30-year-old from Chinese Taipei also showed the benefits of his grueling off-season. Jung effortlessly tracked down heavy shots from Norrie throughout the match that would be winners against many players.

“I felt like my legs let me down a few times in big matches last year that could have had a greater impact on my year-end [FedEx ATP] Ranking,” Jung said. “I could still run and fight, but though the head was willing, the body often was often not. Sometimes, I could feel my legs getting heavy and it probably affected my shot selection, and not for the better.”
