"Riki is the far more senior player with international experience as both a pro and an amateur, and it takes a fair bit to get him rattled," Cassidy said.
"He doesn't hit the ball as far as Fergus but has an excellent short game."
Cassidy said Smith could be a "little bit nervy" going into the final but he was a very good young player capable of putting together a strong game on the day.
"If Fergus gets on a roll it will be a very interesting match," Cassidy said.
Their 36-hole championship match tees off at 8.04am with the other games following on.
The Belmont course is in prime condition for the finals, which will find the best players across men's senior, intermediate, junior and C grade divisions, as well as the best women's players in Silver, Bronze 1 and Bronze 2 divisions.
