Also, nage can try extending uke more, which will cause them to lose balance, and thus, they will be unable to spin out.
This is a very good method. I would also add to this, that you should then roll the uke's hand/arm off of the top of your head and try to place their hand at the bottom of their spine. You must be careful, because this can be dangerous. But is done properly, uke will not be able to spin out, as this will be a very tight application of Shihonage.
