The TSL's match of the round is living up to its billing with Lauderdale taking a one-point lead into the half at Windsor Park.
The Southern Bombers took a two-goal lead into the first break kicking with the wind, but were pulled back in the second term.
Mitch Thorp has been the game's dominant forward with three goals from set shots, while Fletcher Seymour has won 17 touches with good support from Jobi Harper (12) and Tim Bristow (13).
Bombers big man Haydn Smith has been dominant in the ruck and has looked likely up forward.
Lauderdale made three late changes, with ex-AFL duo Josh McGuinness and Jacob Gillbee missing and Nick Dodge's TSL return from an ACL pushed back another week.
