The Tornadoes opened on a 16-1 run as Aaron Krier came out hot again, knocking down three three-pointers in the opening five minutes.
East responded, however, outscoring Storm Lake 30-18 in the second and third quarters, and 15-8 in the fourth.
"They were very aggressive. There's not a lot of second chances," said Storm Lake head coach Bob Grant. "Early on we got some easy looks. We didn't get those same looks later. We stopped attacking. If we've got a lead, we've got to keep going. This is a great lesson for us. We've got to be in better shape. They're a great team. They're 7-0. We gave it a great effort. There's just a few little things we've got to do better."
Krier led the Tornadoes with 15 points on the night and also turned in four boards and three assists. Ethan Kenkel had 13 points and seven rebounds. Jay Grant had nine points and three steals, Yach Deng had eight points and Nic Seaman turned in five.
The Tornadoes (3-4) were 19-of-42 from the floor, 4-of-17 from three and 10-of-18 at the line.
Marcel Dunson led East with 24 points and four rebounds. Wyatt Mounts had 12 points and seven rebounds.
Storm Lake has one game left before the break as they take on a top-10 Spencer Tiger club that enters at 6-1 on the year. Their lone loss came to LeMars in overtime last Friday, 86-80.
