The shape of the senior final changed dramatically when top-ranked Tegwyn Bradley, of Woodville, winner of 14 other finals during the season including the Golden Shears, was eliminated in the semifinals on Saturday afternoon.
Son-in-law of 2017 world champion and employer John Kirkpatrick, Stevens made his intentions clear, more than 20 seconds clear of nearest challengers Mullooly and Pincol through the halfway stage and ultimately shearing the 12 sheep in 13min 58.38sec, half a minute clear of eventual second-man-off and Gore-based fourth placegetter Lionel Taumata, from Taumarunui.
Mullooly was third to finish, in 13min 31.28sec, and was by more than a point the best shearer in the board judging, but suffered in the judging in the pens afterwards.
The 2017 Intermediate champion, Masterton-based Sean Gouk, was fifth and sixth was Whakapunaki (Naki) Maraki, of Flaxmere, who on Thursday was fourth in the Junior woolhandling final won by partner Ngaira Puha.
Stevens has the choice of going up to open grade in both shearing and woolhandling next season, but is still just short of the threshold for upgrading.
