Good effort by Tiafoe. In his position as the huge underdog, he had to win the 3rd-set tiebreaker to go up 2 sets to 1. When he lost, of course the match was done.

BTW, lots of quotes from players (see Novak below) that the Aussie courts are even faster this year. Stinks that Fed is out with injury as he would've enjoyed these conditions.

Spoiler!
