There was a bit of controversy Wednesday at the Australian Open.

Serena Williams was leading 5-1 in the third set of her quarterfinal match against Karolina Pliskova and serving at match point when she was called for a foot fault. After her next serve, Williams injured her ankle and Pliskova rallied for a 6-4, 4-6, 7-5 victory.

A number of people questioned the timing of the foot fault, including commentator Mary Joe Fernandez.

Fernandez wondered about the timing of the call when it happened and as the match started to go in Pliskova’s favor:

“I was almost in the locker room,” Pliskova told the crowd at Melbourne’s Rod Laver Arena, per the Washington Post, “but now I’m standing here as the winner.”
