Thanasi Kokkinakis hopes his turbo-charged US Open triumph over Stefanos Tsitsipas is the spark that finally ignites his spluttering career.
The luckless South Australian rightly branded his 7-6 (7-5) 4-6 6-3 7-5 victory over the Open's 11th seed and two-time grand slam finalist as his finest yet at a major.
"Massive relief," Kokkinakis said after ousting last year's Australian Open runner-up for only his second ever US Open main-draw win.
