A dozen teams will feature in this year's T20 Royal Hotel Cup

Four new sides have flagged their interest in joining the Orange District Cricket Association-run Royal Hotel Cup.

Cowra and Molong have again thrown their hats in the ring after a five-year hiatus from the Twenty20 title race, while Bathurst clubs City Colts and Rugby Union are also keen to have a run at the Bonnor Cup this summer.

ODCA president Mark Frecklington says the addition of that new quartet isn't set in stone, with the preferred option to run a competition with 12 sides, but the added interest of more teams ahead of the looming summer is a boon for the committee.

A decision will be made at the ODCA's annual general meeting on Monday September 21.

If all four are given the green light to join Western Zone's premier Twenty20 competition, it'll take the field out to 13, with last year's champions Cavaliers, Kinross, Bathurst City, Orange City, CYMS, Lithgow, Centennial Bulls, Centrals and St Pat's Old Boys all expected to field sides again this summer.

Frecklington says, however, said it's more than likely just the three will be admitted into the competition.

He said added interest in the Royal Hotel Cup was always welcome, with the 2019-20 title race, won by Cavs in a thriller over St Pat's Old Boys under lights at Wade Park, regarded one of the best Twenty20 competitions in country cricket, not just Western Zone.

"It just adds a bit more variety" Frecklington said looking at the inclusion of more teams in the Royal Hotel Cup.

The variety will also improve the standard of cricket, which is important for Mitchell Cricket Council powerbrokers keen on improving the stocks of the Central West Wranglers - the council's Regional Bash outfit that's now twice won through to play at the Sydney Cricket Ground finals in the last two years.

"We've got four new teams who have been invited but we'll probably take on three ... just so we don't end up with 13 teams," Frecklington added.

"Next Monday are our closing nominations and we should know a bit more about it after that but everyone seems on board for three more teams to join."
