Lance Morris has awoken from his slumber to help inspire a dream session for Western Australia in their Sheffield Shield clash with South Australia at the WACA Ground.
The Redbacks resumed play on day two well placed at 5-276, but they lost 5-21 to be all out for 299.
In reply, WA moved to 0-47 at lunch, with Sam Whiteman (25no) and Cameron Bancroft (21no) at the crease.
Paceman Matt Kelly finished with 5-34 off 27 overs to be WA's best bowler, but it was Morris (4-93) who caused the bulk of the destruction on Saturday.
Morris, who can bowl in excess of 150km/h, returned figures of 1-75 off 18 overs on Friday.
But he came out breathing fire on Saturday on the way to figures of 3-18 during the morning session.
South Australia lost 3-0 during a horror start to the day, with Morris the one who sparked the downfall.
Harry Nielsen (38) was the first to fall when his attempt to fend off a fierce Morris bouncer resulted in a catch to a diving Teague Wyllie at short leg.
Two balls later Nathan McSweeney (67) fell to Kelly, and Morris continued the destruction with the scalp of Ben Manenti for a duck.
Kelly and Morris claimed one more wicket each to wrap up the innings, and WA's dominant start to the day continued as Bancroft and Whiteman combined for an unbeaten 47-run stand.
