Novak Djokovic was seriously rattled early on by inspired American teenager Nishesh Basavareddy but rallied for a 4-6 6-3 6-4 6-2 victory on Monday to keep his bid for an 11th Australian Open title alive into the second round.

After a strong start in his first round opener, Nishesh Basavareddy fell to a 6-4 3-6 4-6 2-6 defeat against Novak Djokovic. The Serbian wrapped up proceedings with ease in the fourth set to qualify for the next round.

With new coach Andy Murray watching on, the 37-year-old Djokovic was flat-footed early on against American wildcard Nishesh Basavareddy before winning in four sets. The 19-year-old Basavareddy, who was making his Grand Slam main draw debut, stunned Djokovic by clinching the first set.

Novak Djokovic set another grand slam record as he battled through to the third round of the Australian Open. The 37-year-old’s 6-1 6-7 (4) 6-3 6-2 victory over Portuguese qualifier Jaime Faria was his 430th match at a slam, taking him past the mark previously held by Roger Federer.

Novak Djokovic added yet another record to his lengthy list, breaking a tie with Roger Federer for the most Grand Slam matches played in tennis history by reaching 430 on Wednesday at the Australian Open in what was a tougher-than-expected second-round victory.
