Rafael Nadal hit but not sunk.
The No. 6 seed overcame Canadian Denis Shapovalov after a five-set match.
Led 2 sets to 0, the young Shapovalov showed character to return to 2 sets everywhere.
Hampered by stomach pains in the fourth set, Rafael Nadal waited until the fifth set to make the difference.
Hanging in his first service games in the last set, Rafael Nadal fought not to let his opponent make the break.
Quite the opposite of a Shapovalov who conceded the entry break on his service, allowing Nadal to lead 3-0.
The Spaniard drew his energy from the public present at the Rod Laver Arena.
Qualified for the semi-finals, Rafael Nadal will face the winner of the match between the French Gaël Monfils and the Italian Matteo Berrettini.
The start of the match is scheduled for around 10:45 a.m.
