New York, NY, USA, 24 August 2018 | AAP/

Australians Alex Bolt, Jaimee Fourlis and Marc Polmans are through to the final round of US Open qualifying in New York.

The 25-year-old Bolt beat El Salvadorian hopeful Marcelo Arevalo 7-6 3-6 6-3 on Court 17 at Flushing Meadows, and will face Thanasi Kokkinakis’ conqueror – 15th seed Yannick Maden – for a spot at the year’s final Grand Slam event.

Maden, of Germany, beat Kokkinakis 7-6(5) 6-4.

Bolt is aiming to qualify for his second straight Grand Slam main draw after winning three matches to make his Wimbledon main-draw debut in July.

Later on Thursday, 18-year-old Fourlis defeated Serbia’s sixth seed Olga Danilovic 4-6 7-6(6) 6-2 while fellow Victorian Polmans saw off American Ernesto Escobedo 6-4 3-6 6-0 in second-round qualifying matches.

Fourlis snapped the six-match winning streak of Danilovic, who recently enjoyed a stunning run to the WTA Moscow River Cup title as a lucky loser.

The victory sets up a final-round clash with Anhelina Kalinina; should she win, it would be the first time Fourlis has come through qualifying to reach a Grand Slam main draw, and it would mark her US Open main-draw debut.

Polmans, 22, finished strongly against the former world No.67 Escobedo and will next play Frenchman Ugo Humbert.

The Aussie is projected to rise to world No.160 – and possibly higher – thanks to his run this week in qualifying.

In other results, Max Purcell pushed 28th seed Casper Ruud in tight two sets 7-6(5) 7-5, while Arina Rodionova fell 6-3 6-1 to American Jessica Pegula.
