MELBOURNE: Andrey Rublev rallied back from the brink to dump Holger Rune out of the Australian Open and book a second quarter-final at Melbourne Park courtesy of a lucky net cord on match point that sealed a 6-3 3-6 6-3 4-6 7-6 (11-9) cliffhanger on Monday. Fifth seed Rublev had to do it the hard way, having been 5-2 down in the final set at Rod Laver Arena and needing to save two match points to take contest into a 10-point tiebreak of unrelenting tension. He slipped 5-0 behind in the breaker but roared back to lead 9-7 before ninth seed Rune saved two match points in a late twist. It took the net cord to separate them, with Rublev’s final return clipping the net and popping over on the third match point, leaving the Dane no chance.
