Swiatek, the highest ranked player left in the event, said after the win Kerber had played a different game to eat she had expected and it too a while for her to figure our how to play her.
“Truth be told, I wasn’t really sure what my tactics should be, if I should be more aggressive or play more patient game,” she said.
“But at the end I think I made the right decision in right time, in right moments of the match.
“I felt like she wanted to use her experience and kind of trick me,” Swiatek said. “But I like that because it’s like a new experience for me.”
