Wow SAI was motivated to defend 2018 Nanchang and DC points :cheer:
I think balance is key. Today Sakkari kinda ended the points prematurely for her, she didn't need to exactly try to overwhelm except mentally. Her depth of shot and pace change can be underestimated as well. It wasn't an easy case of her coughing up attackable balls all the time.Zheng was very very passive with great defence and Sakkari made a lot of easy errors.
SaiSai can play more aggressive and I saw some matches she was going way more for winners and actually made them.
Probably it's her tactic right now, what is more successful and it's confirmed by this result.
