The Swiss had a break point in the fourth against Stak, on a second serve coming in at 86mph. But he'd lost so much confidence in his return at that stage, he impotently sliced it back and let Sergiy right into the point. His ROS has been an issue for some time, yet it's scarcely been more evident than against the man who's retired at Wimbledon three times.
