There was some interesting (read: worrying) body language from Anisimova when she was up 5-2 in 3rd set and she lost a point. She suddenly showed this negative body language as if she was down 2-5. The commentator also pointed this out. I thought she might flipped and lost her focus. Then she suddenly regained her focus just before the next point.
Her focus seems very fragile, but the same can be said about Sabalenka - although less often and Sabalenka pulled through more often than not.
Anisimova has a 6-3 H2H against Sabalenka. Both don't have a very good record of winning the match when coming from behind, but Sabalenka still has better record in this.
