And she was 1st after the short then too ( but by a wider margin). Things are looking good for Mirai.
Yes they are. But you know that overused cliche- "ice is slippery"- well, anything can happen, it's about what you put on the ice when it counts, and nothing more. Practices are mainly to get the jitters out and also to get a feel for the ice.
Also, she is in a virtual tie for 1st with two other skaters. If Nagasu can REALLY knock it out of the park, I don't think the other skaters stand a chance. But if she slips up (and/or is lacking the fire) she could be surpassed.
