Australian Nick Kyrgios beat defending champion John Isner 7-6 (3), 7-6 (4) in the Atlanta Open tennis final to win his second professional tour title.
The second seeded Kyrgios spent one hour and 47 minutes in his first career win over Isner and snap the hard-serving American's 15-match winning streak here on Sunday, reports Xinhua.
"Returning is very crucial against John," said Kyrgios. "That serve is world class."
Kyrgios will rise to a career high ranking of 16 with this win.
He lost to Isner at Association of Tennis Professionals (ATP) Tour tournaments in Madrid and Montreal last year.
