The 32-year-old Scotsman -- who could become the first Wimbledon men's singles champion since Michael Stich in 1992 to win the doubles title -- returned to tennis only a fortnight ago after what he called life-changing hip surgery.

He and Herbert -- who has won all four Slam doubles titles -- gelled as the match went on and beat Romanian Marius Copil and Frenchman Ugo Humbert 4-6, 6-1, 6-4, 6-0.
