Alex de Minaur and Jordan Thompson will joust for a US Open quarter-final spot as Australia's extraordinary assault on the season's last grand slam hit a 36-year high.
De Minaur wore down veteran British marathon man Dan Evans 6-3 6-7 (4-7) 6-0 6-0 to clinch a last-16 berth for a fifth consecutive slam after the seed-slaying Thompson claimed yet another big scalp on day six in New York.
After sending world No.7 Hubert Hurkacz packing in round two, Thompson took out 30th seed Matteo Arnaldi 7-5 6-2 7-6 (7-5) to storm into the fourth round at Flushing Meadows for a second time.
