Northwestern State (12-11) issued 11 walks and had four errors in the game, and eight of the 10 Louisiana-Lafayette (23-2) runs resulted. The Ragin' Cajuns won their 13th straight game, the longest streak in the nation.
Ryan Leonards, who reached on a walk in the third at-bat of the third inning, scored on a bases loaded free pass issued to Tyler Girouard. Seth Harrison, who also reached on four balls, scored along with Caleb Adams on a single up the middle from Jace Conrad.
The Ragin' Cajuns scored three more in the fourth inning, two on a home run from Leonards after an error by Demon third baseman Matt Alford. The freshman dropped a pop up foul ball to allow Leonards to continue his at-bat, and the next pitch was sent over the wall.
Harrison, who reached on a walk, scored the final run of the inning from third base on an error by Edwin Gomez.
Northwestern State scored the game's first run in the opening frame on a hard-hit double to left field of the bat of Cort Brinson to score Joel Atkinson. Atkinson reached on a single to left field in the second Demon at-bat of the game.
Louisiana-Lafayette quickly tied the game in its first inning with a sacrifice fly to left field from Seth Harrison that scored Trahans. Trahans reached on a base on balls, and advanced to third base on a single from Leonards one batter later.
Leonards had four hits in as many tires with two runs scored and two runs knocked in. Trahan drew three walks and Harrison drew two. All but three Cajuns who started finished with a base knock, and all Michael Strentz was the only Cajun not to reach base.
The Demons finished with eight hits, two behind Louisiana-Lafayette.
