This is a good fight between Smith who is one of the better British prospects right now and Appleyard who is a solid domestic fighter. Smith is currently 7-0 but is being progressed quickly and will be fighting for the vacant English Super Lightweight title in this fight.
I think Dalton Smith is better technically due to his amateur pedigree and likely has more power as well. Appleyard has a lot of experience but hasn’t fought for over a year.
I think Dalton Smith will win a decision after ten rounds due to being technically better and also holding the power advantage.
