(CNN) -- This was not how it was supposed to end. 

The past week had been a procession -- the next few days were supposed to end in a coronation. 

With the future King of England in the Royal Box, the man who wore the Wimbledon crown so proudly allowed it to slip on Centre Court. 

Andy Murray, the first British man to win the tournament in 77 years, was not just thrown out of his court, he was brushed aside by a man threatening mutiny at the top of the men's game. 

Grigor Dimitrov has hinted at performances like this before -- but this was the announcement his potential had always promised to deliver. 

The Bulgarian, 23, for so long hailed as the heir apparent to 17-time grand slam winner Roger Federer, is ready to finally erase the tag which has haunted him since he first came to prominence -- that of "Baby Fed". 

Ranked 13 in the world, Dimitrov gave a performance which left nobody in doubt that he is a serious challenger for the title following a 6-1 7-6 6-2 win over the defending champion. 

Never before has Dimitrov gone further than the second round at the All England Club -- now he is just one victory away from a grand slam final. 

But the signs had been there. Dimitrov, who won the Queens Club title - a warm-up tournament before Wimbledon - has been improving with each and every match. 

He will now play his first ever grand slam semifinal against Novak Djokovic -- the 2011 champion and the tournament's top seed.
