But Roger Federer displayed his true class as a champion as he produced some excellent tennis in the fourth set and it seemed that it would go down the wire.
Andy Murray rallied hard but Fedex was equal to the task winning yet another tie-breaker to take the set 7-6. This meant the 5th set would be the decider.
Fedex was found wanting in the 5th set as Murray gained the upper hand but it remained to be seen if the Scotsman could hold his nerve on the brink against the more experienced Swiss.
Andy Murray did hold his nerve when it mattered and won the 5th set 6-2. This was the first time he had beaten Roger Federer in a Grand Slam and will now face Novak Djokovic in the final on Sunday.
