Trobaugh (Gladbrook, Ia.) shot rounds of 34 and 39 for his round of 73. Trobaugh's previous best round was a 75 at the Iowa Lakes Invitational in the fall of 2012.
"Overall, I was really happy with the way I played," Trobaugh said. "It wasn't exactly the easiest day in the world.
"It was gusting up to 20 (mph). I was really happy with the way it went."
NIACC coach Chris Frenz said Trobaugh had everything working on Monday.
"I think his driving was a little erratic on a couple of holes," Frenz said, "but he kept it together. His putting was very good and his short game was very good."
NIACC also received a 79s from sophomores Logan Jarvis (Riceville, Ia.) and Joe Myers (Rockwell, Ia.) and an 80 from Levi Fink (Wadena, Ia.)
It was the second straight day the Trojans claimed a tournament title. They claimed the Iowa Lakes Invitational with a 307 on Sunday.
"It's been a lot of fun," Frenz said. "When it comes to the regional tournament, you have to learn to play back to back days.
"It was nice to come up with a couple of nice wins, even though they were on different courses. You are still playing Iowa Lakes and Iowa Central - teams you are going to have to beat at the regional tournament."
NIACC returns to action Friday at the Southwest Tech Invitational in Spring Green, Wis.
