June 16 (Reuters) - Andy Murray is in the best shape since his hip surgery as the former world number one prepares for a run at Wimbledon, he said after cruising into the quarter-finals of the Rothesay Nottingham Open. "It is really hard to say if I'm playing my best level overall," Murray added. Murray added that he is giving his best as he bids to be seeded by the time of the grasscourt Grand Slam, which runs from July 3-16. "I am doing my best to give myself the best preparation I can for Wimbledon," he said. Murray will play Swiss eighth-seed Dominic Stricker later on Friday before returning to the Queen's Club Championships on June 19.
