Putnam weighed in 48.01 pounds in the event. The final day of fishing was Saturday after high winds kept anglers off the lake Friday.
Putnam had caught 39.03 pounds of walleyes in the first two days to qualify for the finals. Larson was fishing open pockets in weeds about 2-feet tall out of the water, pitching a jig and leech.
His sponsors include Scheels, Yamaha, Ranger and Ray Marine Electronics.
