Alexei Popyrin has taken full advantage of a kind draw to battle into the quarter-finals of the Qatar Open in Doha - but his fellow Sydneysider Chris O'Connell has been knocked out in the last-16.
Popyrin, in his first tournament since getting knocked out by Novak Djokovic in the Australian Open, scrapped into the last-eight by defeating Hugo Grenier, a qualifier ranked 105 places below him, on Wednesday.
