Daniil Medvedev has lost to Novak Djokovic and Rafael Nadal in two Australian Open finals
Third seed Daniil Medvedev was moved hard by Portugal's Nuno Borges yet followed through in four sets to arrive at the Australian Open quarter-finals.
Double cross finalist Medvedev neglected to change over two match focuses at 5-4 in the third set prior to winning 6-3 7-6 (7-4) 5-7 6-1.
"He made me run [in the] third set," Medvedev said. He will confront 10th seed Hubert Hurkacz next after the Shaft finished special case Arthur Cazaux's splendid run.
France's Cazaux had beaten eighth seed Holger Rune in the subsequent round yet couldn't cause one more upset as Hurkacz won 7-6 (8-6) 7-6 (7-3) 6-4.
Later on Monday, Spain's second seed Carlos Alcaraz faces Serb Miomir Kecmanovic.
