World No. 1 Novak Djokovic was off and on, as well, the Serbian losing the first set to Roberto Bautista Agut before nearly a two-hour break. He resumed and led 3-6, 6-4, 4-1 when play was stopped a second time in what appeared to be for good. Just shy of 7 p.m. local time, officials cancelled the rest of the day's play.
