Here's the replay for the two prior runs from that horse -- both at the same class level.

Her jockeys took a hold of her early and in the head-on replays of both races -- you can see she was being sort of eased after she got about 20 lengths behind the next to last horse in the field.
It's pretty mysterious how a horse can perform like that one week and almost win a race at the same level the next week. I could see if there was a layoff line and some vet work was done on her and a little time was given to fix an ailment.
