Carroll entered Monday's contest with a 9-7 record and took advantage of a sluggish start by the Tornadoes, using their long ball approach to pin the ball in the Tornadoes end nine minutes in. Jonny Levia would attempt to head the ball out for the Tornadoes on a cross in from wide, but the junior misconnected and sent the ball past Storm Lake keeper Tony Rolon for an own goal.
The early deficit spurred the Tornadoes to action, and Juan Rosales had a corner pop out to his foot but skied it for for Storm Lake's first chance three minutes later. One minute later, Tornado leading scorer Victor Aviles had a shot on goal, only to see it deflect off the bar and to safety.
At the 18-minute mark midfielder Hunter Lee came free on the left wing and thumped a shot into the side netting from 20+ yards out for the equalizer.
The Tornadoes would keep the pressure up over the final minutes, with Aviles putting two on goal, and another off the cross bar, and Levia and Rosales adding near misses. The score remained knotted at half however, 1-1.
The Tigers' sole reliance on the long ball left at a lopsided disadvantage in terms of possession, but Carroll's all or nothing strategy paid off again four minutes into the second as they blasted the ball deep into Tornado territory. Storm Lake failed to clear, and Austin Smith was able to put the Tigers back out in front.
Finding themselves trailing, Storm Lake snapped back to life yet again and earned a free kick from 25 yards out three minutes later, but Jorge Sanchez's attempt was saved. Five minutes later a Sanchez cross found Aviles, but the Tornado forward was stuffed inside the six-yard box.
At the 23-minute mark, some nifty 1-2 work by Aviles and Edgar Raya inside the 18 put the ball on Aviles' foot at the penalty spot, where he calmly leveled the score with a finish into the bottom right corner.
Carroll's third yellow card of the night gave the Tornadoes a free kick at the 14 minute mark, but Sanchez's cleanup attempt was saved. A nice corner kick in was met by Lee's head, but his well aimed attempt was also denied.
At the 13-minute mark, a handball inside the box gave Storm Lake a penalty attempt, which Raya cooly placed into the bottom right corner.
The wheels began to fall off for Carroll there as Storm Lake earned another corner with seven minutes left. Manuel Ramirez was able to flick the ball across the goal to a waiting Aviles, who netted his second goal of the night with the finish.
One minute later, Sanchez put the game well out of reach as he found the back of the net inside of the 18.
Storm Lake totaled 33 shots in the game with 20 on target. The Tigers totaled four shots on target.

Ronald Duque had two goals, Ramirez a goal and two assists, Sanchez a goal and two assists, Rosales a goal and an assists, Rolon a goal, Jose Candelario a goal, Raya two assists and Abraham Rios an assist.
