McClenaghan will probably always go for a few - it's the way he approaches his cricket - and his raw statistics don't make for particularly compelling reading. He has played 26 first-class matches and snared 76 wickets at 39.03 and this season has 14 wickets from his four Plunket Shield matches at 34.85.
The Aucklander is not short of confidence and regularly bowls in the mid-140km/h bracket and hopes he is a direct replacement for Southee in more ways than one.
"Unfortunately Timmy's thumb wasn't right," McClenaghan said ahead of this morning's deciding Twenty20 international against the Proteas in Port Elizabeth.
"But I'm really looking forward to the opportunity to step into his shoes if I get the chance. I believe I can take wickets and be a lot more threatening.
"I can be used in short spells and hopefully I will be a substitute for Timmy in the wicket-taking department. Most of the boys bowl at a good click but I definitely feel like I can bowl a good spell of heat and put them on the back foot."
It's a triumph for a player who once endured a dreadful run of injuries that included a fractured pelvis, three hip surgeries and a snapped ankle ligament.
More recently he's followed a rigorous crossfit training programme and diet which has seen him give up, among other things, bread and pasta.
"The diet's been massive," he said recently. "No sugars, no breads, no nothing, really. Just good veges and broccoli, lots of broccoli. I've learned to love it."
