RESERVE GRADE: Gatton and Valleys are making a habit of clashing in the TRL reserve grade grand final.

They will battle it out at Clive Berghofer Stadium on Sunday in what will be the fourth-straight reserve grade decider between the two clubs.

Gatton is looking to make it back-to-back titles in reserve grade and holds a 2-1 advantage in deciders the past three years.

The Hawks finished the regular season minor premiers while Valleys have come from third to make the grand final.

Both teams are used to playing big finals games and have players with A grade experience.

Reserve grade starts at 1pm.

GATTON: 1 Alex Groves, 2 Liam Neumann, 3 Wayd Nibbs, 4 Taylar Hawthorn, 5 Riley Godwin, 6 Michael Frohloff, 7 Jagan Swan, 8 Francis Han, 9 Raymond Erbacher, 10 Shaun Andrew, 11 Jayke Jackwitz, 12 Benjamin Itzstein, 13 Cory Schmidt, 14 James Lewis, 15 Todd Bichel, 16 Pisao Faoi, 17 Ryan Leslie, 18 Nash Hawthorn, 19 Clifford Brown, 20 Lachlan Gorman

UNDER 18: The Warwick Cowboys will aim to win the club's first TRL premiership in eight years when they play Valleys in the under 18 decider at Clive Berghofer Stadium on Sunday.

The last Cowboys premiership win was in 2009 when the reserve grade side won.

Warwick comes up against a talented Valleys team though and have a big task ahead trying to beat the Roosters in a repeat of last season's under 18 grand final between the two clubs.

Valleys are also aiming for a third-straight under 18 title as a club.

This should be a good game to watch as future TRL stars are on show.
