MELBOURNE, Jan 23 (Reuters) - Britain’s Kyle Edmund bludgeoned his way past third seed Grigor Dimitrov 6-4 3-6 6-3 6-4 on Rod Laver Arena on Tuesday to reach the Australian Open semi-finals.
The unseeded 23-year-old, playing in his first grand slam quarter-final, showed no nerves as he blazed away with his fearsome forehand to subdue a nervy Dimitrov.
The Bulgarian struggled to reproduce the form that saw him beat home favourite Nick Kyrgios in the previous round, with his serve especially vulnerable.
Edmund broke decisively at 4-4 in the opening set with a thunderbolt forehand off a weak second serve.
Dimitrov took the second set but never looked completely comfortable against the ultra aggressive Edmund and a double-fault at 3-4 in the third set proved costly.
The players swapped breaks in the fourth set but Edmund broke again for a 5-4 lead to serve for the match.
A tense final game saw Edmund double-fault but an ace brought up match point and then Dimitrov sliced a backhand long which was confirmed by Hawkeye.
Edmund is the only British man in the main draw after three-times grand slam champion Andy Murray withdrew to have surgery on his hip. (Reporting by Martyn Herman; Editing by Peter Rutherford; )
