They have been their nemesis all year and the Linton Cobras stayed one step ahead of Whanganui Boxon in the second round of the Western Alliance Premiership on Saturday.
Having previously beaten Boxon 32-22 and 18-10 during the MRL rugby league competition, the Cobras won 20-12 at Springvale Park to confirm they will play the final against the likewise unbeaten Coastal Cobras of Taranaki, who won 32-20 over the Waitara Bears.
Both Cobra teams will meet at the Army camp this weekend in the last round-robin games before the July 16 finals day, while the Boxon will host the Bears at Springvale.
Boxon and the Bears will then meet again in playoff for third and fourth, with the venue likely to be decided by who wins this week.
On Saturday, the scores were locked at 8-8 coming out of halftime, but Linton would score twice in the second-half through replacement centre Caleb Riddick, who had been in the team initially to cover hooker.
