Marinkov defeated the top two seeds during his title-winning run at the ITF J200 event, including a 6-2 1-6 6-1 victory against second seed Charlie Camus in the final.
Camus remains the top-ranked Australian boy at world No.45. The 16-year-old from Canberra left Sydney with two trophies, after teaming with New Zealand's Harry Pugh to win the boys' doubles title.
Hugh Winter, a 16-year-old from Adelaide, has been rewarded for his singles semifinal run, rising 31 spots to a career-high world No.155.
Meanwhile, Cruz Hewitt, the 14-year-old son of former world No.1 Lleyton Hewitt, is the biggest mover inside the Australian top 10.
Hewitt improves 49 places to a career-high world No.327 after a quarterfinal appearance. He is now the ninth highest-ranked boy in the world among 2008-born players.
