After ending their initial season in third place, the Shamrocks had five first place finishes in the next six seasons. They reached the Mann Cup finals in 1953 but found the Peterborough team too tough. It didn't matter to 5800 Victoria fans who jammed the old Memorial Arena to see the action. That support gained the Rocks national prominence and allowed the club to import eastern players. Again, in 1954, they were unsuccessful in the rain and mud at Peterborough's outdoor box. But in 1955 the Shamrocks found the answer and they defeated their traditional rivals in the national final. The Mann Cup came to Victoria. The winning team included Tom Druce, Jim Bradshaw, Arnie Ferguson, Lew Landess, Bob Dobbie, Archie Browning, Nip O'Hearn, Joe Mitchell, Dean Blackstock, Ed Popham, Al Davies, Dusty Mair, Geordie Johnston, Alan Gill, Ralph Baker, Jack Northup, Jim Hetherington, Larry Booth, Red McMillan, Whitey Severson, Bill Bamford, Harry Irwin, Jack Thompson and Jack Bionda. Pickups included Derry Davies and Jake Proctor.
