Strikers hand Scorchers wooden spoon

Jon Wells has spanked a half-century to deliver the Adelaide Strikers victory and the KFC BBL wooden spoon to the Perth Scorchers.

Wells struck 69 from 42 balls as the Strikers downed the Scorchers by five-wickets in Saturday's battle of the also-rans.

Set 175 runs to win, the Strikers reached their target with four balls to spare at Adelaide Oval.

The result ensures three-time champions Perth finish last this tournament.

But reigning champ Adelaide fares little better - they rise to sixth on the ladder but could slip a rung if Sydney Thunder win their last game.

Wells anchored Adelaide's run chase with aplomb after early wobbles - Jake Weatherald (nine), Alex Carey (27 from 18) and Travis Head (10) were all dismissed in the initial eight overs.

Mitch Marsh plunders unbeaten-fifty

But from a precarious 3-64, Wells combined with Harry Nielsen (44no from 29 balls) for a match-defining 88-run partnership.

Wells reached his half-century from 32 deliveries and hit eight fours and a six as Adelaide banked its sixth win of the tournament.

Earlier, Perth posted 6-174 with opener Josh Inglis and Mitchell Marsh making half-centuries and Nathan Coutler-Nile producing a whirlwind cameo, smacking 25 from just eight balls featuring three sixes and a four.

Inglis (55 from 37 balls) and Marsh (50no from 41) were the linchpins while Cameron Bancroft made 22 from 13 deliveries.

Adelaide's legspinner Rashid Khan was the pick of the bowlers, taking 2-22 to finish the tournament with 19 wickets at economy rate of slightly more than six runs an over.
