After an 0-5 start, it was the third win in the last four games for Smithsburg (3-6, 3-3), which amassed 436 total yards while limiting Clear Spring to 72, including 33 on the ground on 20 attempts.
"We've played four good games in a row ... receivers ran nice patterns ... we got good blocking from the line," said Orndorff.
The Blazers (1-7, 0-6), playing with emotion at the outset, forced a Smithsburg punt on the Leopards' first possession thanks to Lorenzo Smith's sack of quarterback Andrew Bohan.
However, two Clear Spring mistakes were damaging.
Vinnie Mills promptly responded with the first of two interceptions of Clear Spring's Tyler Braithwaite. But again, the Blazers stopped Smithsburg on fourth down after the Leopards marched from their own 30 to the Clear Spring 5-yard line.
Mills' second interception set up Thompson's first score from 5 yards out for the lone score of the first period.
"It wasn't just the interceptions, we had mistakes with missed assignments, dropped passes," said Blazer coach John Wilson. "And, we knew what they would do. We just weren't consistent."
The Leopards went to work with a four-TD second period that put the clock in running motion for the second half with a 35-0 lead.
Bohan, who ended 5 of 11 for 90 yards in the air, scored on a 1-yard sneak and followed with a 7-yard scoring toss to Matt Thompson on a fourth-and-7 play. After Smithsburg stopped Clear Spring on downs to set up a short field, Thompson ran in from 6 yards. With 13 seconds left in the half, Bohan hooked up with Dustin Mitchell on a 40-yard completion that set up the same combination on a 6-yard touchdown.
Thompson had six runs of more than 10 yards, including a 46-yarder in the third period that set up a 1-yard score by Chad Brown, who ended the game on a 78-yard touchdown run.
Clear Spring managed to stop Thompson three times for no gain and four other times for two-yard gains, many led by Smith.
"(Lorenzo) had some good sticks on (him)," said Wilson. "He was playing football for the first time this year, He's been good for us."
