The Central Hawke's Bay College product delivered a player-of-the-match performance in the Pirate team's 22-19 Tui Maddison Trophy third-round win in Waipukurau on Saturday to become the 12th weekly winner as the battle to become the 2017 holder of the McDonalds-Hawke's Bay Today Club Rugby Player of the Year award continued.
He was one of two Pirate players of CHB origin - second five-eighth Kane Nepe-Apatu was the other - to shine for the visitors.
"I'm from Otane and Central beat the Pirate boys in the Nash Cup round by one point so it was good to help them get a bit of redemption," Cahill said.
It's no secret the Pirate forward pack can compete with the best in the comp when at full strength. Cahill pointed out their backs are starting to click too.
"Kane and our centre Hayden Hann are starting to develop a good combination. They are not big blokes and I know opposing teams target them but they've got big hearts," Cahill explained.
When the father of two was quizzed about his representative ambitions he replied: "Representative rugby is in the back of every player's mind. But I need to get fit if I want to chase those honours and I'm still learning the locking role. I prefer the 6 or 8 roles but everyone wants to play there. I'll just play anywhere as long as I get a game."
There's no doubt Cahill is not afraid of setting major goals. Nor are his team.
"I know Napier Old Boys Marist are way up there but we'll beat them this round," he said before his dog Rogue barked him back to work.
If Progressive Meats Havelock North's defensive systems remain as flimsy as they were last week and their forward pack is as loose the Pirate team could upset them with a three-point victory at Tamatea Park on Saturday. Expect the defending champions, Hawke's Bay Insurances Limited Napier Old Boys Marist, to retain the Challenge Shield with a 17-point win against Carters Frame and Truss Taradale at Park Island.
The tussle for second place between Ansin & Monteith Hastings Rugby and Sports and Altherm Window Systems Napier Technical has the potential to be a thriller - a six-point victory either way.
Northfuels Central should pip MAC by three points at Waipukurau's Central Park and K9 Petfoods Clive have the potential to beat Tamatea by nine at Farndon Park.
