Jack Draper admitted he needs to overhaul his grass-court game after the British fourth seed suffered a shock Wimbledon exit as former finalist Marin Cilic rolled 
back the years to reach the third round.

Cilic, the Croatian World No. 83, blasted 53 winners in a 6-4, 6-3, 1-6, 6-4 victory that stunned the partisan British fans on Thursday. 

Draper is the new figurehead of British tennis after taking on a role filled for a generation by the now-retired former Wimbledon winner Andy Murray. But the 23-year-old has a poor record at his home Grand Slam. He is yet to make it past the second round in four appearances at the grass-court tournament.
