Australian Open Tennis Day 10: Serena Williams, Novak Djokovic and Kei Nishikori in quarter-final action

WORLD No.1 Novak Djokovic has crushed No.8 seed Milos Raonic to book a place in the Australian Open semi finals.
Djokovic will clash with defending champion Stan Wawrinka in a blockbuster semi-final on Friday night.
The Serbian star took the opening set in a closely-fought tie-break before putting his foot down, winning 7-6, 6-4, 6-2.
The four-time champion broke Raonic early in both the second and third set and the Canadian was never able to recover.
Earlier, Wawrinka was equally impressive as he disposed of No.5 seed Kei Nishikori.
The Swiss No.4 seed was far too good for the Japanese star, wrapping up a straight sets win 6-3 6-4, 7-6.
