Roger Federer survived a huge Wimbledon scare on Tuesday when French opponent Adrian Mannarino was forced to retire injured at the start of the fifth set of their first round tie with the Swiss great admitting: “I got lucky”. Eight-time champion Federer was level at 6-4, 6-7 (3/7), 3-6, 6-2 when Mannarino called it quits after just one point in the decider.
