A determined Denmark-Walpole will be out to end a long premiership drought in the Great Southern Football League colts competition, taking on Royals in a cracking grand final on Sunday at Collingwood Park. The Magpies won their only colts flag in 2004 and tackle the Lions who have been a dominant force in colts since the GSFL was established in 1991. In a season in which their league team struggled, the Magpies have been the dominant side in the colts and remain undefeated heading into the decider. The Magpies have dropped points in only one game this season, playing out a thrilling draw with Albany in round one. Since then the Magpies have rattled off 15 consecutive victories, including a gutsy 11-point qualifying final win over the Lions late last month. Rod Gillies medallist Josh Thompson, star forward Jhett Morrison-Carter key position player Todd Brown and skilful pair Marlon Mastalerz and Sam Ross loom as key figures in the Magpies’ premiership quest. However, the Magpies were dealt a blow in the qualifying final, losing captain Jed Cummuskey to a badly broken arm. The Lions are shooting for a fourth straight colts title and have won five of the last six grand finals. They have regained Rory Luscombe and Ryan Lazar from league duties to complement young stars Teague Valli, Jordan Hulm and captain Saxon Henrickson. The two sides will square off in the colts decider at 10.30am. Meanwhile, a highly anticipated fixture between bitter rivals the Lions and Railways will take place in the reserves grand final. The Tigers were undefeated up to round 10 before suffering a defeat to Albany and then lost to the Lions and the Sharks again in round 13 and 15, respectively. The Lions were 24-point winners in the qualifying final but a spirited display from the Tigers against North Albany in the preliminary final earned them a deserved grand final berth. The two sides have split their four encounters this season and the Lions are chasing back-to-back flags. The reserves decider starts at 12.15pm. In the 16s competition, the Sharks and Lions will do battle at 8.45am.
