“Bryan Lutter (third leading wicket taker) is a pretty good story. He played fourth grade last year and he has worked really hard and has gone from fourth grade to first grade.
“Simon Acomb was a last-minute decision but has been a top Twenty20 performer and is the top wicket-taker.”
Batsman Aaron Keverne-Onyon has been a top-performer with the bat in the competion, scoring 225 runs in five games at an average of 75.
“He hits the ball as clean as anyone I have ever seen,” Neretlis said.
Fremantle has had a strong tournament and has boasted Perth Scorcher players Sam Whiteman, Shaun and Mitchell Marsh, Jhye Richardson and Ashton Turner.
According to Fremantle coach Joe Piromalli, the Port Boys will be without the Scorchers stars.
“We won’t get any of the Scorchers, who play Hobart the day before the (Premier Cricket T20) grand final,” he said.
“It would be great to have them but the rest will step up,” he said.
Piromalli said the wicket would play a role in how his side approached the match.
“Generally the Fletcher Park wicket is batter-friendly,” he said.
“We haven’t talked tactics so far.
“It will depend on the wicket.”
