Australian Open 2017: Top 5 upsets from Week-1

#1. Novak Djokovic’s shocking defeat to Denis Istomin

Denis Istomin scripted the upset of the tournament by defeating reigning champion Novak Djokovic in the second round

Novak Djokovic had a brilliant start to 2016 but a couple of inconsistent performances compounded with Andy Murray’s consistency saw him lose the No.1 ranking to the Scot. Djokovic began 2017 well by winning the Qatar ExxonMobil Open by beating Murray in the final. Coming into the Australian Open, Djokovic was in search of a record seventh title here and was one of the favorites to win the competition.Djokovic’s first round opponent was Fernando Verdasco who was a semi-finalist here in 2009. Djokovic comprehensively beat Verdasco in straight sets to set up a second round clash against wildcard Denis Istomin who had beaten Croatian qualifier Ivan Dodig in the first round. Istomin began the match brilliantly by taking the first set 7-6 but Djokovic rebounded well by taking the second and the third sets.Istoming held his nerve and took the fourth set through a tiebreak before winning the final set and scripting one of THE upsets of the Australian Open in its 112-year old history. This was Djokovic’s first second round defeat since being defeated by Marat Safin in the 2008 Wimbledon Championships. The 117^th ranked Istomin won another five-setter in the third round against Pablo Carreno Busta and will now take on an in-form Grigor Dimitrov in the fourth round.
