Nathan Coulter-Nile's record-breaking innings set-up Australia's 15-run victory over the West Indies at Trent Bridge on Thursday.
Australia were reduced to 38 for four after the West Indies fast bowlers rattled their top-order.
But Coulter-Nile’s career-best 92, which is the highest score by any number eight batsman or lower in a World Cup, powered them to a decent 288.
He alongside Steve Smith (73) bailed Australia out with a partnership of 102.
In reply, West Indies finished on 273 for nine with contributions Shai Hope and skipper Jason Holder.
West Indies vs Australia Highlights
Fast bowler Mitchell Starc did most of the damage with a five wicket haul for 46.
The West Indies had knocked Pakistan out for just 105 at Trent Bridge with a barrage of short balls and adopted quite similar strategy against the Aussies.
Oshane Thomas had Finch (six) caught before opening partner David Warner (three) guided the ball straight to backward point off Sheldon Cottrell’s bowling.
Smith got a sigh of relief on 26 when he top-edged a hook off Holder only for Cottrell at long leg to slip as he aimed for a catch.
His patient knock ended when he flicked Thomas high towards deep backward square only for Cottrell to complete a scintillating catch at the boundary.
But Coulter-Nile continued the assault as he crossed his previous international best of 34.
In the West Indies' run-chase, opener Chris Gayle, having overturned two onfield out decisions, was eventually pinned by Mitchell Starc for 21.
But Hope took his time as he completed his fifty off 76 balls.
Holder then accelerated the innings with couple of well-struck boundaries.
But West Indies suffered a massive blow when Hope chipped a slower ball off Cummins to mid-on, setting the stage for Starc's five-wicket haul.
