Australian Open: Djokovic Dismisses Dimitrov, Murray Out

Novak Djokovic continued his charge towards a 10th Australian Open Title with a superb 7-6 6-3 and 6-4 victory over Bulgarian Grigor Dimitrov to reach the fourth round, but fears about the durability of his injured left hamstring only grew.

Fourth seed Djokovic looked uncertain in his movement during a roller-coaster first set where he began with a break, squandered three set points at 5-3 and dropped serve late on before edging a thrilling tiebreak.

A heavily-strapped but more aggressive Djokovic emerged from a medical timeout and built pressure with his relentless returns from the back, going up 4-2 as 27th seed Dimitrov hit the net to surrender his serve, and went on to wrap up the second set.

Former world number one Andy Murray's incredible run in Melbourne ended in the third round as the 35-year-old lost 6-1, 6-7, 6-3 and 6-4 to Spain's Roberto Bautista-Agut.

Three-times major winner Murray came into the match on the back of marathon contests in the first two rounds where he knocked out 13th seed Matteo Berrettini and local hope Thanasi Kokkinakis.

American Ben Shelton, 20, reached the last 16 of a grand slam for the first time in his career after beating wildcard Alexei Popyrin of Australia 6-3 7-6(4) 6-4.
