Lancaster moved on after scoring a convincing win 9.19 (73) to 4.2 (26) over Tallygaroopna.
Despite a criminally inaccurate scoring performance, the Wombats domination of the midfield ensured the Redlegs chances were few and far between as they rolled to the easy victory.
Girgarre wasn’t so lucky on its own day of poor accuracy, upset by Avenel 6.3 (39) to 2.6 (18).
In a low-scoring affair, the Swans made the better of their limited chances, sending the Roos home in disappointing fashion after Girgarre (13-3) only missed the top two on percentage.
Lancaster and Avenel will look for a preliminary final berth against either Nagambie or Murchison-Toolamba.
