John Isner and Dan Evans ease into Delray Beach quarter-finals

Second seed John Isner had no problems booking his place in the last eight of the Delray Beach Open while Dan Evans also enjoyed a straightforward victory.

American Isner was a 6-4, 6-3 winner over Slovakian Lukas Lacko in one hour and 11 minutes, breaking once in the first set and twice in the second.

“It was a good win. I think I’m getting more comfortable on this surface, especially with the positioning on my return… I was challenging him on a lot of return games,” Isner said.

“I was very happy how I came through that.”

He will take on Adrian Mannarino next after the eighth-seeded Frenchman beat Denis Istomin of Uzbekistan 6-2, 7-6 (7-3).

Evans, meanwhile, strolled into the quarter-final as he secured a 6-0, 6-2 win over wildcard Lloyd Harris from South Africa in one hour and nine minutes.

Up next is sixth seed Andreas Seppi after the Italian beat Jordan Thompson from Australia 6-3, 4-6, 6-1.
