After initially giving away a body length to Hamilton's Bradlee Ashby over the initial butterfly leg, a strong backstroke pulled him level and a sub 1:15 breaststroke split saw Capp move away for a comfortable victory. His time of 4:21.54 was a new personal best and Bay of Plenty record but five seconds shy of a ticket to Scotland.
On the opening night Capp set another BOP record touching third in the 400m freestyle behind Matamata's Matthew Stanley. His time of 3:54.10 removed Rotorua's Kane Radford's name from the record books.
Capp remains hopeful of selection for New Zealand teams in either the upcoming Oceania Championships or the world class Pan Pacific meet where his times met B standards.
Meanwhile, his sister Claudia Capp and Danielle Waiari both competed in their first Open Championships. Claudia was successful in reaching the B final of the 50 Freestyle where she broke a BOP age group record swimming 27.66 seconds. Waiari swam a personal best 28.45 in the 50m freestyle while her best result was a 24th in the 50m backstroke.
