MELBOURNE, Australia — Kei Nishikori rallied from two sets down and won 10 consecutive games before Kamil Majchrzak retired with the score at 3-6, 6-7 (6), 6-0, 6-2, 3-0 at Margaret Court Arena.
Nishikori had a chance to win the second set, up 30-0 on the Polish player's serve at 5-4. But he let Majchrzak back into the game and when the set went to a tiebreaker, two unforced errors by Nishikori handed his opponent the set.
Those mistakes riled Nishikori between the second and third sets, obviously upset with himself as he placed ice cubes in a plastic bag on the back of his neck.
