Novak Djokovic now has 14 Grand Slams against his name to move into a tie for third on the all-time list alongside Pete Sampras.
A season that started gloomily with elbow Surgery after the Australian Open is turning into a brilliant finish for the 31-year-old Serb who has now won three of his last four events including back-to-back majors at Wimbledon and flushing Meadows.
Over the last eight weeks Djokovic has resembled the grand slam machine that held all four Major titles at the same time in 2016.
Playing on the same Court where Pete Sampras claimed his 14th and final Grand Slam Crown, Djokovic had endured more disappointment than joy on Arthur Ashe, mining just three titles from eight finals.
The disappointment on Sunday belonged to a teary Del Potro who was back in a Grand Slam Final for the first time since the big argentine won his one and only title at flushing meadows in 2009.
