A tight first half gave way to a runaway Rochester at Kings Park.
The Tigers led by just eight points at quarter-time but the Lions were unable to get the ball forward after the break, producing just a single point for the second quarter.
Rochester squandered its opportunities in front of goal as their tally of behinds quickly outweighed their majors.
The Lions got one back through Brent Le Cerf at the start of the third quarter to look half a chance against the visitors, but Seymour struggled to get the ball forward after that and the Tigers looked a comfortable 24 points in front at the final change.
Seymour brought the game back to within three goals in the final term, but couldn’t produce an unlikely come-from-behind win.
Score: Seymour 4.5 (29) lt Rochester 7.12 (54).
Goals: B. Le Cerf, T. Clarke, H. McLean, A. Galofaro.
Best: J. Morgan, A. Galofaro, B. Gregson, J. Zuccala, D. McLarty, B. Tarran.

James Shaw opened the scoring for Rochester just on the opening minute before Michael Quinne levelled the scores for Seymour at the 14th-minute mark of the opening term.
The two sides were locked in a tussle back and forth and neither side was really able to capitalise on their use of the ball.
The Lions edged ahead before quarter-time and extended their lead after the break.
Tom Davey produced the lone goal of the second quarter as both sides struggled to produce a major.
A renewed Rochester came out to spoil the party after the half-time break, kicking three goals and restricting Seymour to just one point.
The very gettable eight-point three quarter time margin was too much for the Lions to chase down, as the Tigers scored again to end the very low-scoring contest well in the lead.
Score: Seymour 3.5 (23) lt Rochester 5.9 (39).
Goals: T. Davey, S. Durham, M. Quine.
Best: D. Fisher, M. Quine, H. Jones, T. Davey, B. Bowe, S. Durham.
