Physical woes dog Novak Djokovic in shock US Open first-round loss, first in 20 years
Argentinian Mariano Navone wins in five sets at Flushing Meadows, as Novak Djokovic says he’s suffered ‘every match’ this year

Novak Djokovic suffered his earliest grand slam exit in 20 years in New York on Sunday and said he doesn’t know the solution to the physical problems he’s battled in “pretty much every match” this year.
Argentine Mariano Navone’s 7-6, 5-7, 4-6, 6-2, 6-1 victory in the first round of the US Open ended Djokovic’s latest bid for a record 25th grand slam title.
It also ended his run of 78 first-round victories in major tournaments, a streak stretching all the way back to a 2006 loss to Paul Goldstein at the Australian Open.
Djokovic vomited on court and struggled with late-match cramps and back pain – an “awful feeling” that he’s becoming used to.
