Edmund is now only the sixth British man to reach the final four at a major in the Open era.
The world No 49, whose ranking will undoubtedly sky-rocket once the tournament finishes this weekend, proved he can mix it with tennis’ biggest stars on the main stage at a Grand Slam.
He had previously not progressed past the second round at the Australian Open throughout his career but Edmund has now exceeded all expectations.
He went into the match against Dimitrov as huge underdog and understandably with the Bulgarian third favourite to win the tournament after Novak Djokovic’s defeat yesterday.
But Edmund proved he wouldn’t be beaten easily straight from the off as he broke Dimitrov’s serve in the very first game.
Dimitrov soon levelled the scores, but Edmund once again broke in the ninth to have the opportunity to serve for the match.
His opponent failed to take advantage of three break points though with Edmund going on to take an early
Edmund failed to capitalise on his performance in the first set with Dimitrov taking a 3-0 lead in the second after breaking the Briton’s serve.
And the 23-year-old was unable to claw his way back as Dimitrov levelled up the match.
With the match tied, both players knew the importance of taking the third set.
And neither of them gave anything up on their service games until the ninth when Edmund was handed a lifeline.
The Briton had two chances at break point, but despite spurning the first opportunity, his opponent then double-faulted giving Edmund the chance to serve to take a 2-1 lead.
In unchartered territory, Edmund would have been forgiven somewhat for collapsing under the pressure.
And Dimitrov was doing everything he could to get back in the match.
Edmund showed no signs of slowing down with his ferocious forehand causing Dimitrov all sorts of problems, and he went a break up midway through the set.
However, the 26-year-old wasn’t behind for long as he held his nerve to break back immediately.
But just like in previous sets, Edmund broke when it mattered most in the ninth for him to serve for the match.
And the Brit held his nerve to see off his opponent as the crowd erupted into cheers to set up a potential clash with either Rafael Nadal or Marin Cilic in the final four.
