The Wave forced a season-high six turnovers, four of which were returned for touchdowns, in their 35-14 Division 1-6A victory over Grenada on Friday.
"I've been doing this about 40 years and I've never seen a night where you had four defensive touchdowns that were as pivotal as they were," said Tupelo coach David Bradberry.
Tiggs brought in half of his team's turnovers on three interceptions to bring his total to four on the season. He returned two of those for scores.
His first pick-six came in the second quarter and with his team down 7-0 following a 44-yard fumble return for a touchdown by Grenada's Javoris Redditt. Tiggs read Payne Horan, the Chargers starting QB, perfectly and 41 yards later the game was tied at 7-7.
After Tupelo (3-3, 1-1) went three-and-out on its opening drive of the second half, Tiggs caught a ball that went through the hands of Ole Miss verbal commitment Trey Bledsoe and took it 28 yards to put the Wave up for good.
"There isn't much I can really say about it, but I just put my heart out on the field tonight," said Tiggs. "It was a good day to play football."
Two fourth quarter scoop-and-scores by Demarcus Rogers and Marcus Robinson sealed the win for Tupelo.
The Golden Wave offense showed signs of brilliance as well with a 10-play, 66-yard drive in the third quarter. After a holding penalty forced second-and-long, Thomas Harris kept the offense on the field with a 14-yard QB scramble.
Otis Wilson's 3-yard touchdown five plays later put Tupelo up 21-7 heading to the fourth quarter.
Grenada (3-3, 1-1) made things interesting for a time in the final period. A recovered fumble by Chance Simmons set up Devin Howard 's short scoring run to cut the Wave's lead to two scores.
The Chargers attempted an onside kick after the score and Nathan Evans came up with the ball in the pile.
After a conference, though, the officials awarded possession to Tupelo and said Reed Taylor received the kick and hit the ground before Evans got the ball.
"There again, it's a game of inches and breaks," Bradberry said, "and our guys really battled."
