Robertson and his guide, Captain Joe Rodriguez of Homestead, Fla., caught two weight fish and scored two releases to take a commanding lead on day one.
They maintained their lead on day two with two more releases and one weight fish.
Robertson’s final score of three weight fish and seven releases overall moved him into the winner’s circle.
Each angler in the tournament is allowed to “strap out” (measure the tarpon’s girth using a strap) five fish, and release fish only count toward a win when a weight fish is caught. Tarpon must be 70 pounds to qualify as a weight fish.
As well as the overall win, Robertson scored a 108-pound tarpon that landed him the tournament’s Billy Pate Memorial Largest Tarpon award.
The tournament’s first runner-up was Texas resident Ryan Seiders, guided by Islamorada’s Captain Rob Fordyce, with two weight fish and three releases.
Twenty angler-and-guide teams competed, posting a total of 50 tarpon releases and eight weight fish.
The 20th annual Outback Golden Fly Tarpon Tournament is set for May 18-21, 2014.
