Alex de Minaur has shown extraordinary resilience to bounce back from the depths of misery and book an "incredible" place in the last-four of the ATP Finals in Turin.
The Australian No.1, a picture of despair just a couple of nights earlier after feeling he'd thrown away victory during defeat to Lorenzo Musetti, started his unlikely resurrection with a backs-to-the-wall 7-6 (7-3) 6-3 win over Taylor Fritz on Thursday, his first ever victory at the season-ending championship.
Then after achieving the two-sets-to-nil triumph - the only way he could stay in the tournament - de Minaur owed a huge vote of thanks to Carlos Alcaraz, who sealed the end-of-season world No.1 ranking by beating home favourite Musetti 6-4 6-1.
