May be the maps are in favor of Scarlett right now and for aggressive early and middle game zergs. But this doesn't change the fact that she really played well and to be honest, I wanted for her to grab this trophy, despite that sOs is one of my very favorite players all times. After so many years I wanted to see Scarlett with a major tournament trophy especially if you defeat one of the very top players right now and for the last 4-5 years.
Actually both of them demonstrated good defence and micro. I think in this case it was a matter of will and Scarlett really wanted this. She took more risky strategies and it worked for her.
