Novak Djokovic struck back for the old guard at the Australian Open early on 21st January, soaking up the pressure from an impressive Daniil Medvedev before crushing the young Russian 6-4 6-7(5) 6-2 6-3 to reach his 10th quarter-final at Melbourne Park, Reuters reports.
The Russian wearied in the constant attrition during Monday's fourth round match, and top seed Djokovic ended up cruising to victory soon after midnight, having easily passed his biggest test at what had been a trouble free tournament.
The world number one did not emerge entirely unscathed, however, and was troubled by a back strain in the last set.
Djokovic said, "I didn't feel so great in the last 20 minutes of the match, so we'll see tomorrow how the body reacts,".
He added "It was just a little bit of fatigue, a little bit of back, nothing major ... But there are a couple of things that have surfaced."
Djokovic will continue his bid for a hat-trick of successive Grand Slam triumphs and a record seventh title in Melbourne against eighth seed Kei Nishikori, who squeezed past Pablo Carreno Busta in a five-set epic.
