Frazier's five goals broke the record of four that was accomplished last year by Laykn Brooks and Kelci Winn.
Frazier now has 22 goals on the season, one more than Winn scored all of last year in establishing that mark. Her five hat tricks are the most in a season, and Frazier has scored at least one goal in all eight of Trigg County's games this year.
Brooke Allen, Amanda Want, and Taylor Davis each had an assist for Trigg County, who fell to 5-3 on the season.
Trigg County played the game without second leading scorer Kelci Winn, who sat out the final game of a two-game suspension for her actions in receiving a red card at Reidland last week. Brooklyn Thomas also did not play, still having one more game to serve on her three-game suspension for her actions in the same game.
Trigg County will host Webster County tonight at the Complex.
Elsewhere, Madisonville hammered Fort Campbell 10-2.
In other games Tuesday, Union County visits Crittenden County; Todd County Central travels to Grayson County; Hopkinsville visits Mayfield; Caldwell County is at University Heights; and Christian County visits Warren East.
