Western Australia lost their last eight wickets for just one run in an extraordinary collapse against Tasmania in Australia’s domestic 50-over competition.

The three-time defending champions reached 52-2 but were bowled out for 53 amid a flurry of wickets on a bouncy, green pitch in Perth.

The one run added came from a wide, with numbers five to 10 in the batting order all dismissed for ducks.

Tasmania seamer Beau Webster took 6-17 and fast bowler Billy Stanlake 3-12. Tasmania chased their target in 8.3 overs for a seven-wicket win.

The collapse was made more remarkable by the fact all 11 of Western Australia’s XI were Australia internationals.

It was the second-lowest score in the tournament’s history, only beaten by South Australia’s 51 against Tasmania in 2003.

It is also the worst eight-wicket collapse in Australian domestic 50-over cricket, beating the previous professional record of 8-24 by Victoria in 2002-03.
