Alex de Minaur has crashed out of Queen's at the first hurdle in a serious blow for the Australian No.1 with Wimbledon looming.
But there was a much better outing for Alexei Popyrin, who has the tools and form to spring a surprise at the London grand slam, and enjoyed a very useful work-out in beating compatriot Aleksandar Vukic in three sets.
There was also a shock main court appearance for Adam Walton, who was suddenly called up to face world No.2 Carlos Alcaraz as a lucky loser. That was because Alejandro Davidovich Fokina - who had come to England after getting married in Marbella, Spain, at the weekend - had withdrawn with illness.
