She did show an ability to turn matches around from behind a year ago, just before she got to #1. At the AO she was a set down to Cirstea in the last 16, then a set down to Kanepi in the QF (think she saved match points in that one?) although I do remember her having a mental breakdown in both matches and didn't seem to know what to do. I think she won those matches just from pure guts and determination rather than strategy.It's too early to say weather her game has ATG characteristics, when you look at goats of any sport they have the ability to get in the zone, problem solve and make adjustments. She hasn't had many chances to show that yet as she's too good at front running and the odd chance she does she collapses. The come back against Saba at USO down a break in the third is what goats do all the time but let's see if it's repeatable. Rybakina comes down from 4-1 frequently but she's the worst starter, susceptible to early breaks.
Then at Indian Wells last year she won 3 matches in a row from a set down, and those were far more impressive because her opponents were playing a high level at the start but I don't remember her panicking. She just raised her level several gears and comfortably beat them.
She has an extremely high IQ (like Emma) so I think she can problem-solve to some degree. It's more the mindset with her, that she's very self-centred and focused on what she wants to do.
