LONDON, July 1 (Reuters) - British hope Andy Murray and five-times champion Roger Federer charged headlong towards a Wimbledon final showdown on Wednesday while two of the game's wiliest campaigners were conspiring to gatecrash the party.

The top seeds recorded emphatic victories on another sun-baked day on Centre Court, as Tommy Haas stunned fourth seed Novak Djokovic and Andy Roddick was the last man standing in a gripping four-hour gunfight with old foe Lleyton Hewitt.

Less than 48 hours after putting his mother, girlfriend, 15,000 Centre Court fans and millions of British television viewers through the wringer with his electrifying five-set win against Stanislas Wawrinka, Murray produced a no-nonsense 7-5 6-3 6-2 win over Juan Carlos Ferrero.

While the authoritative exhibition gave Murray a place in the last four at Wimbledon for the first time, the sight of all-conquering Federer at the tail-end of a grand slam is taken for granted these days.
