Ferrer continues fine form in Cincinnati

Veteran Spaniard David Ferrer cruised into the last eight of the Cincinnati Masters on Thursday with a comprehensive 6-4, 6-4 win over compatriot Pablo Carreno Busta.

The win saw the former world number three earn his first ATP Masters 1000 quarter-final since November 2015, where he will face third-seed Austrian Dominic Thiem.

Thiem saw off France’s Adrian Mannarino via two tiebreaks in a tense affair 7-6(4), 7-6(3).

"Against Ferrer it's going to be a long and physically tough match," said Thiem. "He's playing way better again, including a great match against Federer last week. It's going to be really tough but I've got some more confidence again and I hope I'm ready."

Ferrer needed just 77 minutes and two breaks of serve to beat Carreno Busta (11), the breaks coming in the fifth game of the first set and at 1-1 in the second.

He is now 11-2 since losing in the third round at Wimbledon.

Home favourite John Isner joined the duo in the last eight after overcoming Frances Tiafoe, the conqueror of Alexander Zverev, 7-6(4), 7-5 in two hard-fought sets.

Isner faces another American in the next round in Jared Donaldson, who defeated Georgia’s Nikoloz Basilashvili 6-4, 7-6(4).

Grigor Dimitrov also made the quarters after beating his doubles partner Juan Martin del Potro 6-3, 7-5 in one hour and 39 minutes.

He now faces Japan’s Yuichi Sugita for a place in the semifinals.
