MELBOURNE, Jan 22 (Reuters) - Novak Djokovic showed no signs of any lasting fatigue to overcome Czech fifth seed Tomas Berdych 6-1 4-6 6-1 6-4 on Tuesday and advance to the Australian Open semi-finals.
The world number one, bidding to become the first man to win three successive Australian Open titles since the game went professional, had been forced into a marathon five-set, five-hour fourth round clash against Stanislas Wawrinka on Sunday.
Berdych had felt that energy sapping clash could give him an opportunity to secure his second career win over the Serb and first since their Wimbledon semi-final in 2010.
Djokovic, however, bounced on his toes throughout and effortlessly scrambled and slid across court to wrap up victory in two hours, 31 minutes and set up a semi-final clash with Spain’s David Ferrer. (Writing by Greg Stutchbury; Editing by Pritha Sarkar)
