Victoria will face Queensland in the Ryobi Cup final after Western Australia failed in their bid to secure a bonus point win in their last regular season match against Tasmania at the WACA on Tuesday.
West Australian captain Mike Hussey won the toss and elected to bowl, and Tasmania amassed 6-307 off their 50 overs.
The Warriors needed to chase down the total inside of 40 overs and despite being in front of the run rate in the early stages of their innings they continued to lose wickets at regular intervals.
After a blazing start from Liam Davis (28) and Sam Whiteman (13), which yielded 40 runs off the first four overs, the openers fell in consecutive balls to end the fifth over and start the sixth.
When Mike Hussey (four) top-edged a James Faulkner delivery and Ben Dunk took a well judged catch running back the Warriors had slumped to 3-51.
Mitch Marsh (104) then combined for a 49-run stand with Hilton Cartwright (20) and an 87-run partnership with Ashton Turner (51).
Marsh's knock included six fours and five sixes as he looked to guide the Warriors to an unlikely victory.
It took a sublime piece of Ricky Ponting fielding to end the innings as he threw down the stumps from backward point after a mix-up.
James Faulkner (3-62) was the best of the Tasmanian bowlers while Timm van der Gugten (2-44) and Evan Gulbis (2-57) were the other multiple wicket takers.
Earlier in the day, Tasmania had made a solid start to their innings before Burt Cockley (2-91) struck twice to remove openers Johnathon Wells (19) and Ben Dunk (10).
Former Australian Test captain Ricky Ponting (95) then combined with Australian Twenty20 captain George Bailey (38) for a 92-run stand that moved Tasmania into a commanding position.
Ponting was run out on 95 by Mike Hussey as his former Australian team-mate swooped onto a ball dropped onto the onside by Jordan Silk and threw down the stumps ahead of a diving Ponting.
The former Australian skipper lobbed his bat into the air with disgust when the third umpire's decision was displayed.
Western Australia had helped Ponting along to his total of 95 after dropping him on four and 39.
Silk (66) atoned for his error in judgement of the single that brought about the end of Ponting with some lusty hitting that helped Tasmania reach their total.
Faulkner's (59 not out) was the perfect foil for Silk before he took over and smashed 18 off the last over.
