Juan Martin del Potro cruises into Delray Beach last eight but Nick Kyrgios falls
Top seed Juan Martin del Potro has eased into the quarter-finals of the Delray Beach Open, but Nick Kyrgios crashed out.
Del Potro is playing his first tournament since breaking his kneecap in October, but he quickly found cruise control as he dismissed Reilly Opelka 6-4, 6-4 in just 73 minutes.
Another American, Mackenzie McDonald, now awaits in the last eight.
Krygios, meanwhile, was issued a code violation for an altercation with a spectator en-route to a 6-2, 3-6, 6-3 defeat to world number 82 Radu Albot.
Albot’s reward is a quarter-final opportunity against fourth seed Steve Johnson, who beat Paolo Lorenzi 7-5, 7-5.
“I was having a hard time being accurate with my shots, so I’m glad I served well today,” said Johnson.
“I’m happy I have a chance to play another competitive match tomorrow and hopefully clean things up.”
Meanwhile, Britain’s Dan Evans will meet sixth seed Andreas Seppi, and second seed John Isner faces Adrian Mannarino.
