"I was pretty pissed off - I felt I was playing well enough," said Nukunuku last night. "There was no way I was throwing the towel in, and with the world championships to be played every two years from now, I felt I could play in maybe three more.
"But my heart had been broken, I hadn't seen it coming, there had been no warning from the coaching staff. I was told that I didn't fit into the game plan. I wanted to prove a point. The Black Sox are my passion."
Nukunuku spoke to Aucklander Haretuku and said the player was gutted. "I feel for him but it is the coach's call," Nukunuku said.
Casley had shoulder surgery late last year and has aggravated the problem. His batting is not affected but fielding is another matter.
Kohlhase said: "Rhys is integral to the Black Sox and is our leader on and off the diamond. It's imperative we keep working to maximise his contribution. We were forced to make a difficult decision that would cost someone their place through no fault of their own."
While the Black Sox have had a defeat-laden build-up as they seek to reclaim the title won by Australia in 2009, Nukunuku said they had been facing top local players who knew their game inside out.
