Things started slow for the Bulldogs and they found themselves down 20-12 after the first quarter.
Le Mars tried to make up for lost ground but could only cut the Tigers' lead by two, going into halftime down 32-26.
"We didn't necessarily play poorly in the first half, we just didn't play overly inspired," LCS coach Dave Irwin said. "It wasn't the start I was hoping for from our guys after our nice game on Tuesday (against Western Christian)."
Determined to get back into the game, the 'Dogs came out of the locker room with energy and zest.
"The whole story of the game for us was our second half effort defensively," Irwin said. "We held them scoreless for 11 minutes. We played with a lot of purpose and a lot of passion in the second half."
Le Mars started shutting Spencer's offense down with four minutes left in the third quarter. The reward came in the form of a 46-41 lead going into the final stanza.
The 'Dogs defensive stand continued while they continuously extended their lead. At the final buzzer, the 'Dogs had turned a six point deficit at the half into a 13-point victory.
"Good teams find a way to rally. They rallied around each other and got the job done. I couldn't be more happy for them," Irwin said.
Le Mars junior Jake Irwin had a team-high 16 points by the end of the night. Sophomore Tyler Borchers followed with 14. Seniors Kyle Dolph and Parker Rolfes had 10 points each. Rolfes also had four assists.
Borchers led his team defensively with nine rebounds. Rolfes grabbed five steals.
"Parker Rolfes really changed the momentum defensively in the second half," Irwin said. "He was diving on the floor, giving himself up for an extra possession. When one guy does that it becomes contagious and then all our guys followed suit."
The win puts Le Mars at an overall record of 10-4. They will travel to Cherokee on Tuesday.
Irwin said he hopes that his team will find consistency in this crucial stretch of the season.
"Every game we play from here on out is all in preparation for a tournament run," he said.
