Western Australia 5 for 279 (Voges 64, M Marsh 60, Ronchi 57*) beat Victoria 8 for 277 (White 60, McDonald 52) by 5 wickets
Luke Ronchi blasted a half-century that delivered the second loss in four days for Victoria. After being defeated by Queensland on Wednesday, the Bushrangers went down in the final over in Bunbury when Ronchi lifted Darren Pattinson for six to long-on to take the hosts to a five-wicket triumph.
The result was in doubt until Ronchi arrived to muscle his way to 57 from 35 deliveries, finishing the contest with three balls remaining. Adam Voges, with 64, and Mitchell Marsh (60) had set the platform before Ronchi arrived to make sure of the win that puts them back to third on the table.
Cameron White's 60 and Andrew McDonald's 52 set up Victoria's total after most of their main batsmen contributed. McDonald opened and gave his side a strong start, following Chris Rogers' departure in the eighth over, with a run-a-ball half-century before Brad Hodge (42) and David Hussey (36) chipped in.
The Bushrangers were guided through the second half by White, who had three sixes in his 80-ball occupation, and a late push came from Matthew Wade's 19 from 10 deliveries. Ashley Noffke led the hosts with 3 for 43 on his return from an ankle problem while Brad Knowles was rewarded with two wickets.
