"He plays with tremendous confidence and may well step in local high performer Rod Bannister's shoes if we can encourage him to continue in the sport," Roestenburg said.
"There is plenty of experience in the team, with the extended squad having a record it is very proud of with 20 team wins in 21 team ties over four years - a winning percentage of 95 per cent. Along the way they have won three regional graded and two national titles."
Whitlock is also a standout performer, moving from E2 to B2 grade in three years and has never been beaten in any grade in four years.
"He was in the national winning E grade team, along with Hamza Ali in 2013. Shane Stone, Brett McKenzie and Rob Moore were also members of the national D grade title winning team in 2012."
Roestenburg said each year the squad targets a grade and commits fully to a six-month exhaustive training schedule.
"There's nothing flash about what we do, we use Pak'n Save plastic cups for cones, old rope for skipping, and run the stairs to empty the tanks. We also commit to some skills improvement, and most importantly, back all our team members 100 per cent win or lose," Roestenburg said.
The National C Grade event runs from today until Saturday.
