Top dogs Alex de Minaur and Daria Kasatkina have expressed relief for different reasons after saving Australia's blushes with contrasting second-round US Open victories in New York.
As Alexei Popyrin, Adam Walton, Tristan Schoolkate and Maya Joint all crashed out, de Minaur hit the go button in a straight-sets victory over Japanese qualifier Shintaro Mochizuki.
The eighth seed did not have it all his own way, de Minaur staving off 11 break points in the opening set before seizing control for a 6-2 6-4 6-2 victory on showcourt Stadium 17.
