Rising Brazilian star Joao Fonseca was knocked out of the Australian Open in the first round after struggling physically in defeat to American Eliot Spizzirri.
Fonseca, the 28th seed, made his big breakthrough at last year’s tournament as a qualifier as he defeated top-10 player Andrey Rublev, but fell at the first hurdle on his return to Melbourne as Spizzirri claimed his first Australian Open win.
