Goffin stuns Zverev; Herbert advances at Halle Open

Halle - German struggled to find his rhythm against world number 33 Goffin

World number five Alexander Zverev suffered a surprise 6-3, 1-6, 6-7 (3/7) quarterfinal defeat by Belgium's David Goffin at the Halle Open.
Home favourite Zverev was playing with a swollen knee after slipping and hurting himself in the first round, and the Halle crowd watched on in dismay as he struggled to find his rhythm against world number 33 Goffin.
The 22-year-old served nine double faults in a rollercoaster match, and survived two match points in the third set before ultimately losing in the tiebreaker.
Meanwhile, Andy Murray's Wimbledon doubles partner Pierre-Hugues Herbert is hoping to meet Roger Federer in the last four after reigning champion Borna Coric retired hurt in the quarterfinals on Friday.
Herbert won the first set 7-5 against Coric before being granted passage to the semifinals when the Croatian retired with what appeared to be a back problem.
