Novak captured his eighth ATP World Tour title of the season and 56th of his career over no.3 seed Rafael Nadal 6-2, 6-2, in the final of the China Open on Sunday.
The world no.1 beat no.6 seed 7-6 (5), 6-7 (4), 6-3, 6-0 to win an eighth major, joining Jimmy Connors, Ivan Lendl and Andre Agassi in fifth place on the Open Era major titles list.
The victory which brought Novak the second Championships trophy and seventh Grand Slam title also means he will reclaim the no.1 spot in the ATP Rankings on Monday.
