RIka's main competitors for the silver are Young and Evgenia (not technically, but because Evgenia's judging has been biased to the end of the world and back). If Young lands her own 3As, Rika might want that 3Lz. That said, she should be untouchable if she lands all her jumps. I'm obviously excluding Sasha because Rika realistically needs the 4S for that.
Her SP run through was fairly positive overall. Clean 3A despite skating second, so it's looking good. The 3Lo was a bit wobbly, but I'll attribute that to skating second and not having time to warm up her jumps. Let's see how the evening session goes. Maybe she'll try a lutz.
