"Regan has played in two tournaments already this summer and won them both," Waterhouse said.
He was referring to the fact Regan plays for Christchurch United as well as Maraenui Pumas and the Christchurch side have won tournaments in Christchurch and Nelson this season.
With such firepower on the mound, it will be a surprise if Hawke's Bay don't improve on last summer's fourth placing at the NFC.
Waterhouse's son Jordan, who played in the 2011 NFC but missed last summer's, former Junior Black Sox utility Jovaan Hanley and his Saints clubmate Tiaki Tewheoro are others on the Hawke's Bay roster who are all capable of pitching at this level if required.
Another feature of the Bay team is the return of enigmatic former Junior Black Sox catcher Grant Dean, who played for Waikato at last summer's NFC. Dean is back in the Bay and playing for the Fast Pitch club.
Others capable of catching for the Manley brothers in the Bay side are Dean's Fast Pitch clubmate Te Rangi Chadwick and Pumas Karaitiana Aranui.
The Hawke's Bay NFC squad will form the nucleus of the Hawke's Bay Selection which will take on the Black Sox at Akina Park in Hastings on November 18.
Co-coaches Corey Tamati and Scotty Mitchell intend to add several more players to their squad for the Black Sox doubleheader as they anticipate losing a couple of their 15-strong NFC squad to the Black Sox team who will make an internal tour this month as part of their World Series buildup.
Unbeaten teams Fast Pitch and GSB Building Saints will meet in the feature Hawke's Bay premier men's match tomorrow.
It's a huge weekend for Fast Pitch, who will meet Poneke Kilbirnie and Miramar on Sunday when they play in the Wellington-based intercity competition.
Napier Vikings and Pumas will chase their first win of the season in tomorrow's other premier match.
