Battling Bernard Tomic has enjoyed the best win of his stuttering 2017 season, beating Mischa Zverev to advance to the quarter-finals at Eastbourne.

Tomic, who has dropped to No.60 in the world after a poor first half of the year, downed the sixth seed 6-3 6-2.

The older brother of rising star Alexander Zverev, Mischa has had a breakout 12 months himself, beating Andy Murray enroute to his first grand slam quarterfinal at the Australian Open.

But the 30th ranked German couldn’t keep pace with Tomic in their second round encounter on Thursday.

Tomic needed just a single break to take the opening set.

The Australian lifted on both serve and return in the second set to claim another two breaks and the match in a breezy 51 minute performance.

It was the first time Tomic had beaten a player inside the top 50 in 2017.

He’ll play the winner of France’s second seed Gael Monfils and England wildcard Cameron Norrie for a spot in the semi-finals.
