Logan trounced the second-placed Boomers 90-65 in Bulleen in its final WNBL regular season encounter on Saturday night.
But it was not enough for the visiting Thunder to rise into the top half of the competition, having lost to the Spirit in Bendigo on Friday night.
Sara Graham and Renae Camino scored 17 apiece and Cayla Francis added 16 for Logan, which finished 12-10 and needed two wins on its Victorian road trip to see finals action.
The Boomers got 19 points from Rachel Jarry at the Veneto Club, but their finals place has been long since assured.
Bendigo could have advanced if Canberra had upset Townsville on Saturday night in far north Queensland, but the Fire were comfortable winners 106-94 over the Capitals at home.
And Dandenong locked up third place on the ladder as it crushed the league-leading Lightning 82-51 in Saturday's early game.
But despite the thrashing, the Lightning will still host Bulleen in the major semi-final next Saturday.Tags: wnbl, basketball, sport, logan-city-dc-4114, bulleen-3105 First posted February 18, 2012 23:21:19
