That pair saw the required run rate sky-rocket and, while Jimmy Neesham (21 from 17) and Nathan McCullum (35 from 21) put up some fight, Otago's hopes were virtually extinguished when Colin de Grandhomme pulled off a stunning outfield catch to dismiss the latter.
De Grandhomme's snag helped the big-hitting batsman find revenge after McCullum dismissed him cheaply in Auckland's innings, a wicket that seemed to bode well for the southern side's chances. After all, allowing de Grandhomme and Colin Munro to combine for only 26 runs would have been a sure blueprint for success, were it not for Nicol's match-winning knock.
The opener provided the cornerstone for Auckland's innings, unfazed by the regular loss of wickets around him. Nicol smacked eight fours and three sixes en route to 77 from 54 balls, being dismissed from the final ball of the penultimate over.
The damage had already been done by that point, with Nicol enjoying handy partnerships with Brad Cachopa (21 from 22) and Robbie O'Donnell (19 from 10) to accelerate the scoring rate as the innings progressed.
Warren Barnes was the pick of the bowlers for Otago, taking 3-33, but McClenaghan was the unquestionable hero after finishing his four overs with figures of 3-23.
