FAA struck first in a humid opening set to put it on his racquet at 6-5. He couldn’t serve it out though, spraying three consecutive unforced errors. Two points later, a double fault confirmed the No. 2 seed would stick around longer.
Auger-Aliassime maintained the advantage to ride out the second set, 6-3, with the Rod Laver Arena roof partially closing while the players finished it out. A long backhand by Medvedev ended the set.
Medvedev saved a crucial break point at 1-1, 30-40, in the third set with just his third forehand winner—this one an inside-out bullet. Both faced moments of pressure later: Medvedev holding from 4-4, 0-30 and FAA from 4-5, 15-30, before arriving at another tiebreaker.
At 2-3 in the fifth set, Auger-Aliassime took a medical timeout to receive treatment on his right ankle.
