Heavyweights Holger Rune and Grigor Dimitrov both survived scares as the tournament's top two seeds safely progressed to the second round at the weather-hit Brisbane International.
Rising Australian Max Purcell threatened to send top-seeded Rune packing before the Danish sensation eked out a 4-6 6-4 6-2 victory on a Monday program decimated by rain.
Second-seeded 2017 champion Dimitrov then also recovered from a set down to deny former world No.1 and five-times Australian Open runner-up Andy Murray 4-6 7-5 6-2 in a battle of two of tennis's old warriors.
