Andy Murray knocked out of Australian Open 2017

   Andy Murray's hopes of winning a first Australian Open title ended with a shock defeat by world number 50 Mischa Zverev of Germany in the fourth round.

   Murray, the world number one, dropped serve eight times as Zverev won 7-5 5-7 6-2 6-4 on Rod Laver Arena.
  According to reports, It is the Briton's earliest defeat in Melbourne since 2009, and the lowest-ranked player he has lost to at a Grand Slam since the 2006 Australian Open.
   Zverev goes on to face Roger Federer or Kei Nishikori in the quarter-finals.
