Trailing 7-17 in the decider, An’s chances of staying alive looked all but over. While nobody dared to believe, An, with her unflinching confidence and unmatched temperament, fitness and skills, won the next 10 points. Yufei still had four match points in hand, but An, a mentality monster, pulled off the unthinkable to win the decider 23-21 and progress to the final.
