Blaine Alexander scored Trigg's lone first half goal off a penalty kick and appeared to have a second right before halftime, but it was disallowed due to an offsides call.
Caldwell County then scored three goals in the first 10 minutes of the second half to take a 5-1 lead. Clark Adams scored a goal off an Alexander assist to round out the scoring.
"Lapses in concentration have become far too common for this team, but I guess it's a symptom of our youth," Wildcat head coach Josh Nichols said after Trigg fell to 1-4-1. "We lost because of a terrible 10 minute span and our complete inability to put away open breakaways. I still think we have the pieces to be a very good team, but we have a lot of work to do."
Caldwell County improved to 6-0, marking their best start in school history.
Trigg County returns to action Monday as they host Lyon County at the Complex.
Trigg County won the JV game 7-1 behind a hat trick from Kyle Bleidt and two goals from Zeb DeHart.
