Rafael Nadal, the top seed, is out of the Australian Open due to an injury.

Rafael Nadal, who has 22 Grand Slam titles, was knocked out in the second round by Mackenzie McDonald, an American who has never ranked in the top 40 in the world.

Melbourne, Australia (Reuters) – Rafael Nadal’s career ended abruptly, and then gradually.

Nadal injured his hip while chasing down a shot in the eighth game of the second set against Mackenzie McDonald in the second round of the Australian Open on Wednesday. His worried gaze was drawn to his coaches, who were seated courtside at Rod Laver Arena. He then knelt in a corner to catch his breath. He returned moments later to continue, because for Nadal, the only thing worse than losing is quitting.

Knowing his day and tournament were almost over, he watched two aces fly by, bringing him to the verge of losing two-sets-to-love to McDonald, a 27-year-old American who has never ranked in the top 40 in the world. McDonald had played the match of his life for nearly two sets before doing what he needed to do to win 6-4, 6-4, 7-5 over an ailing Nadal, who hobbled around the court for nearly an hour like a wounded deer.
