Injured opening batsman Ben Smith returns and Dean Robinson leaves the squad. So does seamer Bevan Small, who Malan wants to see recuperate, physically and mentally after a draining summer.
Seamer Blair Tickner is on bereavement leave. Enter right-arm seamer Ryan Watson, 22, of Taranaki, the highest Furlong Cup wicket taker, although he's likely to be 12th man.
"There's something about him so we'll see what he's about," Malan said of the 22-year-old swing merchant but rain is forecast.
The teams:
CD STAGS: William Young (c, Taranaki), Doug Bracewell (HB), Tom Bruce (Taranaki), Dane Cleaver (wkt, Manawatu), Liam Dudding (HB), Greg Hay (Nelson), Ajaz Patel (HB), Navin Patel (Manawatu), Mitch Renwick (Manawatu), Kurt Richards (HB), Ben Smith (Wanganui), Ryan Watson (Taranaki).
Coach: Heinrich Malan.
OTAGO VOLTS (possible): B Wilson (c), R Duffy, M Bracewell, A Kitchen, J Neesham, D de Boorder (wk), M Craig, C Viljoen, C Smith, J Duffy, J Hunter, B Soper.
