Ugo Humbert will not go into unfamiliar territory on Saturday in the third round of the Australian Open, where a high altitude challenge awaits him, against Holger Rune, world No. 10 and winner of the last Masters 1000 at Paris-Bercy . Last year, he lost twice quite sharply against the Dane mounted on springs (6-3, 6-2 in Indian Wells in the spring then 6-4, 6-2 in Basel in the fall). There are, however, reasons to hope for a more favorable outcome for the French, this time.
