Junior Jake Hammerstone's 45 sparked the Hornets to a runner-up showing on Monday at Meadow Lakes Country Club.
Fulton logged a 195 to finish behind Southern Boone (179). Linn posted a 230 to come in third, while host New Bloomfield did not field enough golfers for a team score.
Southern Boone's Gannon Kesterson medaled with a low score of 38.
Senior Matt Henry and junior Gage Oestreich notched matching 48s for the Hornets, while senior Austin Wilson added a 54.
"We obviously still have some room for improvement," Fulton head coach Pat Kelley said. "I think Jake shot pretty well for the first time seeing Meadow Lake.
"We still have to, somehow, some way, find some consistency."
Both the Hornets and New Bloomfield will play at the Southern Boone Invitational at 9 a.m. Wednesday at Eagle Knoll Golf Club.
