"Collectively, we had quality, and it was just my day today."
That's an understatement. After Michael Bates picked up Otago opener Craig Cumming in the fourth over, it was all McClenaghan, as he sent eight consecutive Otago batsmen back to the pavilion.
He bowled Hamish Rutherford - coming off two centuries in Otago's recent draw with Northern Districts - with the first ball of his third over, triggering an epic collapse from the visitors.
In McClenaghan's next over, Darren Broom became the first of four Otago batsmen in a row to be caught behind by Gareth Hopkins. That streak was broken by Neil Wagner who instead chipped one to Colin de Grandhomme, reducing Otago to 37-8.
Mark Craig and Nick Beard put on 14, the Volts' best partnership, for the ninth wicket before McClenaghan rounded out his eight-for, the first of his cricketing career at any level.
Three Auckland bowlers have taken nine wickets in an innings - two of whom did so in the 19th century - but McClenaghan was denied that honour by his "good mate" de Grandhomme, who claimed the last wicket to fall.
"There were a few jokes thrown around and I'm pretty sure he'll offer to buy me a dozen of beers after the game."
McClenaghan has already taken three five-wicket bags this summer, and another in the second innings would put him close to Auckland's best bowling in a match, 14-63 by AW Rees in the 1889/90 season.
"I'll give that a crack."
He said the Colin Maiden Park pitch - a batting paradise for much of the summer - offered little assistance to the bowlers, and the only thing he did differently from previous outings came in the form of a slightly-altered run up, one he may have to keep.
"This is the first game where I've changed the angle in my run up to get a little bit of variation, and it worked a gem."
In reply, Jeet Raval (81no) and Neal Parlane (39no) backed up McClenaghan's efforts to give the Aces a dominant lead at stumps.
In the day's other games, competition leaders Northern Districts made 309 against second-placed Wellington, with Daniel Flynn (68) and Pete McGlashan (52no) making half centuries, before the hosts reached 32-0 at stumps.
In Nelson, bottom-placed Canterbury ended the day on 341-5, thanks to an unbeaten century from recent Black Cap Tom Latham and Peter Fulton's 88.
