After an evenly matched first quarter, the game was tied 15-15.
It was in the second stanza that the 'Dogs let the Indians gain control of the game and Le Mars found themselves behind 25-34 at the half.
It took some adjustments at halftime for the 'Dogs to come back. They managed to take the lead and finished the third quarter up 49-45.
"At halftime we just talked about the fact that we're not good enough to not play our best every night," Irwin said. "We came out and we really made a defensive statement in the third quarter and that led to some easy offensive opportunities."
Once ahead, Le Mars never let go of their lead and brought home the fourth consecutive win of the year.
Junior Jake Irwin had five threes in the second half, and senior Brenden Collins added another three.
"That's a pretty big momentum change," Coach Irwin said.
Jake Irwin led the 'Dogs with 17 points, followed by sophomore Tyler Borchers with 13 and Collins with 11.
Senior Tanner Anthony contributed a team-high six rebounds on the defensive end.
"Everybody contributed," Coach Irwin said. "We did a really nice job of finding guys when they were shooting the ball well. It was a very good team defensive effort in the second half."
Le Mars will face Emmetsburg at home on Friday.
"We just want to continue where we left off tonight," Irwin said.
