As Mounds View coughed up three crucial second-half fumbles, Eastview answered each time with a heavy dose of sophomore Will Rains.
The Lightning's 215-pound running back rushed for 190 yards and four touchdowns, as Eastview scored 26 second-half points in a 36-21 victory at Mounds View.
Eastview advances to the Class 6A quarterfinals.
"It was really a back-and-forth game there for a while," Eastview head coach Kelly Sherwin said. "So, to get those turnovers was huge. Those were huge, huge plays for us."
Trailing 14-10 to start the third quarter, Eastview forced a fumble on Mounds View's first play from scrimmage. Rains carried the ball on all five plays of the Eastview possession, eventually capping the 36-yard drive with a touchdown run from a yard out.
Minutes later, Mounds View muffed a punt and Eastview recovered. Rains again ended the drive with a touchdown run.
He added another scoring run on fourth-and-goal from the 1-yard line midway through the fourth, putting the game away.
"He is a really special player," Sherwin said of Rains. "There aren't a lot sophomores who can do what he can do. He runs hard, and the play just never ends when he's on your team."
