It would've been a mess if the set had ended with that set point. However Wozniacki (and many other girls) should learn to use their challenges better, she clearly wasted one or two in that set. The line umpire should be fired tho.
If you're asking how it develops, basically the eight players are divided into 2 groups. The two players from each group with the most wins advance to the semifinals and then to the final
Both Maria and Caro deserves to win this.
