Mother Nature was the winner at the Cincinnati Masters, where Novak Djokovic's last-16 showdown with defending champion Grigor Dimitrov was postponed due to wet weather.
Juan Martin del Potro, Milos Raonic and Pablo Carreno Busta advanced before the heavens opened up on more than one occasion.
Former world number one and 10th seed Djokovic lost the first set 6-2 but rallied to win the second 6-3 before a rain delay.
The rain stopped briefly as Djokovic broke fifth seed Dimitrov for a 2-1 lead in the third and deciding set but proceedings were eventually halted for good until Friday.
Croatian seventh seed Marin Cilic and Karen Khachanov were level at 1-1 in the third set and Stan Wawrinka was leading Marton Fucsovics 2-1 in the opening set, while Roger Federer and David Goffin did not make it out on to the court for their matches.
DEL POTRO DOMINATES CHUNG
World number three Del Potro wasted little time dispatching Australian Open semi-finalist Hyeon Chung 6-2 6-3.
Playing for the first time his rise in the rankings, Del Potro earned his fourth successive Cincinnati last-16 appearance.
Del Potro was due to face Nick Kyrgios for a spot in the quarter-finals later on Thursday but rain ruined those plans.
RAONIC PREVAILS IN ALL-CANADIAN AFFAIR
The quarter-finals await Raonic after he got the better of countryman Denis Shapovalov 7-6 (8-6) 6-4.
It has been all about Shapovalov in Canada amid Raonic's form and fitness issues but the 2016 Wimbledon runner-up showed he is still a force to be reckoned with.
Standing in the way of Raonic and the semi-finals is either Djokovic or Dimitrov.
Spanish 13th seed Carreno Busta, meanwhile, accounted for Robin Haase 6-4 6-2.
