Black Sox captain Nathan Nukunuku may very well stay on to sort out some unfinished business

The 39-year-old was a part of the New Zealand side that finished fourth at the Softball World Championships this week in Prague, ending a run of 10 straight tournaments finishing first or second.

Nukunuku says he's undecided on his future at this stage, but admits had they won the world champs, it may have been a different story.

He says most athletes want to leave the team in a better place, but he'd be leaving this team as a fourth place side as oppose to the number one side.
