MELBOURNE (Reuters) - Grigor Dimitrov reached his first grand slam quarter-final in over two years on Monday by defeating an injury-hampered Denis Istomin 2-6 7-6(2) 6-2 6-1 to end the Uzbek wildcard's fairytale run at the Australian Open.

Istomin, who sensationally knocked out six-times champion Novak Djokovic in the second round, laboured with a hip injury after taking the first set and 15th seed Dimitrov took full advantage on a scorching hot day at Margaret Court Arena.
