John Isner moved into his 11th career ATP Masters 1000 semifinal with a swift 6-1, 6-4 dismissal of Hyeon Chung on Wednesday at the Miami Open.
Isner got off to a near-perfect start, securing a break at 2-1 and letting out an earth-shaking roar. While the 6'10" American is famous for his virtually unbreakable serve, Chung had not yet been broken in Miami. A closer look shows that the 21-year-old South Korean hadn't faced much of a test until Isner, cruising past Matthew Ebden, Michael Mmoh and Joao Sousa.
The world No. 23 may have gone into his quarterfinal match with a little edge having beaten Isner in Auckland earlier this year, but it didn't show.
“I didn’t make too many changes, I just felt like I’m certainly playing much better now,” Isner said. “I benefited from him not playing too well. It was a combination of me playing very well and him being a little bit off. That’s how tennis goes sometimes and I’ll take it.”
