This is what I didn't understand. The timing of the medical timeout was obviously unlucky for Leylah, but in a way it was unlucky for Emma as well. She was sitting there for 5 minutes, probably thinking about having to face a break point after the treatment - that can't have been easy.
I also can't understand why Leylah chose to have that animated discussion with the supervisor. I mean, if Emma had taken a medical timeout due to cramp, you could be forgiven for thinking, does she really have a cramp or is this some tactical BS? But Emma's scratched leg and the blood was clearly there for everyone to see, and of course the umpire didn't force her to continue playing with blood running down her leg. I mean, why on earth would Leylah get worked up over this? I don't get it.
