Canterbury remain eight points clear of Auckland, who beat Otago on Thursday, and 14 points ahead of Northern Districts, who today wrapped up a nine-wicket win over Wellington.
Wellington gave themselves a glimmer of hope at victory in the morning when Michael Papps and Brent Arnel added 89 for the final wicket of their second innings. Papps finished on 160, making 59 per cent of Wellington's total of 269.
ND were left needing 159 for victory, and lost Henry Cooper early, but Dean Brownlie (76) and Bharat Popli (75) combined to make the chase a cruise for the hosts on the slow wicket. Wellington strangely bowled both their wicketkeepers, with Tom Blundell and Luke Ronchi bowling eight overs between them.
Canterbury take on Wellington in their final round, needing an outright win to claim the title without having to rely on other results going their way. Conversely, they will raise the Shield if Northern Districts and Auckland fail to record an outright win against Otago and Central Districts respectively.
In the event of a tie at the top, Canterbury hold the relevant Net Runs Per Wicket tiebreaker by a significant margin.
