Unseeded Czech Jiri Lehecka toppled sixth seed Felix Auger-Aliassime 4-6 6-3 7-6(2) 7-6(3) to reach the quarter-finals of the Australian Open on Sunday, as the exit of yet another big name left the Grand Slam thin on star power for its second week. With holder Rafa Nadal and second seed Casper Ruud going out early, and other title hopefuls such as Daniil Medvedev and Alexander Zverev also exiting, a path was clearing for Auger-Aliassime to go deep at Melbourne Park.
