With every playoff game, Poly's coach Roger Wrenn is getting closer to the end of his coaching career.
Wrenn is retiring after 40 years of coaching in Baltimore City, but the Engineers (11-0) extended his lengthy run another week by routing visiting Perry Hall, 50-21, in a Class 4A North Region semifinal Friday night.
"I know the end is near," Wrenn said. "But I am just trying to enjoy it and it has been such a magic season."
Poly (11-0) advanced to play the Catonsville-Paint Branch winner in the regional final next Friday.
Against Perry Hall, Wrenn faced a team coached by Keith Robinson, a former assistant of his at Patterson.
Robinson started his coaching career under Wrenn, a long-time Perry Hall resident, in 1995 and called him a mentor.
The two hugged after the game as Wrenn teared up.
"He is like a father to me," Robinson said. "I coached at Overlea, too. So I was always around him. I took in as much as I could from him."
Poly rolled up a season-high 433 yards (303 in the first half) of total offense, including 361 yards rushing.
Senior running back Jamal Chappell sparked Poly in the first half, rushing for three touchdowns and 161 yards on 15 carries. Quarterback Derrell Milburn threw for a touchdown and rushed for another. Poly's Brandon Owens contributed 72 yards on six carries.
Defensive back Jordan Garrison led Poly's defense with three interceptions.
Perry Hall committed three turnovers in the first half and four overall as the Engineers limited Perry Hall to 43 yards of offense in the first half.
Poly (11-0) needed only five plays to score. Chappell's 46-yard run set up Priestly Shuler's 2-yard plunge up the middle 2:37 into play.
Chappell ran in the two-point conversion to put the Engineers ahead, 8-0.
After Perry Hall went three-and-out on its first series, Poly increased its lead to 14-0 on Chappell's 50-yard run off tackle.
On Perry Hall's second play of its third series, defensive back Jordan Garrison picked off Mike DeBaugh's pass and returned it 38 yards for score to boost the Engineers' lead to 22-0.
Perry Hall's third series also ended in disaster when Garrison intercepted DeBaugh again.
Chappell capped a 10-play, 53-yard drive with a 1-yard run on fourth down to give his team a 30-0 lead.
Poly finished its first-half scoring when quarterback Derrell Milburn teamed up with Garrison on a 30-yard pass.
Jeremiah Johnson returned an interception 102 yards for a touchdown, DeBaugh threw touchdown passes to Sean Taylor and Jimmy Reed and Jake McQuay kicked extra points to accounted for Perry Hall's second-half points.
"We came out flat and you can't come out flat in the playoffs," Robinson said
