LIVONIA — Guy Mistretta told his Livonia Wildcats he would not accept a repeat performance of its first-round playoff game.

His players apparently took his word.

Top-seeded Livonia avoided last week’s slow start and swung through the gate early to shut out 16th-seeded Mansfield 27-0 Friday in Class 3A regional playoff action.

Senior wide receiver Stephan Guidry scored two touchdowns in the first half off passes from junior quarterback Cee Jay Powell, while Malcolm Dedrick punched in both scores in the second half.

Powell completed 9 of 13 passes for 134 yards, while Guidry took four passes for 64 yards.

Dedrick tallied 123 yards on 20 carries to lead the Wildcats ground game.

“After last week, that was the one thing we stressed,” said Mistretta, whose team was sluggish early in a first-round win over Baker. “It wasn’t that we played bad last week — it was three turnovers, so I wanted to make sure we hung on to the ball all night.”

Livonia scored on four of its six possessions.

The Mansfield offense, led by senior Letiedrick Pugh, kept Livonia defenders busy much of the night.

The Wolverines used a series of short gains to cross into Livonia territory on the opening drive, but Christion Edwards intercepted a desperation pass from Pugh, who was under pressure from strong safety Bryce Jones.

Livonia scored six plays later when Powell connected with Guidry on a 9-yard pass with 5:54 left in the first quarter.

The returning kick started its Mansfield at its own 15. A loss of yards on Pugh’s handoff to Levonte Hall and Jones quarterback sack sealed a punt deep in Wolverine territory.

The field position enabled Powell to connect with Guidry on a 38-yard scoring pass that gave the Wildcats a 14-0 lead with 3:51 left in the first quarter.

Mansfield (6-6) converted twice on fourth-down attempts in the first half, including one at their own 10 with five minutes left in the second quarter.

The Wildcats halted another Mansfield scoring attempt on a fourth down just before the halftime when defenders stifled the Wolverines inside the 5.

“We knew were playing against a good team, and when you play against a good team, you have to watch their tendencies,” Mansfield coach Glen Hall said. “We knew they’d turn and run on the punt, so we’d call the fake and go for it on fourth.

“When you play a team that good, you have to do whatever you can do to stay in there.”

Dedrick took the workload in the second half. He scored at the 8:57 mark in the third when he broke through the middle on a 4-yard scoring run. His TD capped a seven-play, 66-yard drive that began with the opening kickoff.

He fended off a pack of Wolverine defenders in the fourth on gains of 9 and 6 yards before he punched in the score on a 3-yard run with 5:58 left in the game.

Livonia travels to Rayville for 3A quarterfinal action Friday night.
