Dolphins winger Jamayne Isaako marked his 100th NRL game with a personal haul of 18 points to help his side beat the Dragons 26-12 on Thursday night in Redcliffe.
Most of the damage was done in a six-minute period midway through the first half, during which time the Dolphins scored 18 unanswered points to set up a 18-12 half-time lead which they never looked back from.
Earlier the Dragons kicked a penalty goal and crossed through Jack Bird to take the initial lead, but from that point on Toby Couchman's try right before the break was all they had to cheer for.
