Matt Koch led three Braves in double-figure scoring with 16 points, followed by Tyler Jones 12, and Brock Dagel 11. Taylor Anderson led Storm Lake with 13 points, and Michael McCabe and Courtney Goodchild added 10 apiece.
Koch and Dagel paced Cherokee in rebounds with six each, and Kyle Schuck grabbed five. Storm Lake sank seven three-pointers to stay in the game, many of those in the third quarter.
The Braves made 18-41 field goals for 44 percent, and cashed in 7-13 free throws. The Tornadoes meshed just 2-2 from the line.
Jones and Dagel led Cherokee in assists with four each, and Jones and Koch registered three steals spiece to win that category.
"It was a good game for us," said Cherokee coach Bart Smith. "We knew Storm Lake could hit the three-ball and we defended them pretty well. They're a dangerous team that can get hot shooting the ball. We guarded them well most of the game. We don't give up shots in the paint so teams need to shoot from the perimeter to get to us.
"We had some good scoring opportunities and I thought Matt Koch did a good job creating his shots. Our defense was good most of the time to hold them to 45 points after they scored in the 80s against Spencer."
