Lucas Roselli set the tone for Upper Dublin on the team's second play from scrimmage against Unionville.

The 5-foot-8, 155-pound senior escaped along the right sideline en route to an 88-yard score, marking the first of five first-half tallies for the hosts.

Roselli and the No. 2-seeded Cardinals blasted the No. 11 Indians, 40-7, in Saturday afternoon's PIAA District 1 Class 5A semifinal in chilly Fort Washington.

Again pushing aside his smaller frame and an injury that slowed him earlier this season, Roselli carried 16 times for 150 yards and scored three touchdowns. He also returned two kickoffs for a combined 51 yards.

"I think my vision and cutback ability are two of my biggest assets," the 17-year old said. "Also, I make the most of the strong blocking by our linemen."

Upper Dublin (11-1) will face No. 5 seed West Chester Rustin (10-2) for top honors next weekend.

Roselli's 60-yard grab with 18 seconds remaining before intermission gave the hosts a 33-0 cushion.

"It was a check at the line of scrimmage," said Roselli, a midfielder in lacrosse. "I ran a seam route, [quarterback] Mike Slivka pretty much threw the ball up there, and I just ran under it."

The Cardinals opened the second half with an 11-play, 65-yard series that was capped by Roselli's 8-yard TD run and brought on a running clock because of the 35-point mercy rule.

Roselli, who doubles as a free safety, intercepted a pass late in the second quarter at the Upper Dublin 13-yard line to end an 11-play Unionville drive.

The Cardinals' other first-half scores were fullback Mason Novak's 5-yard run, Slivka's 1-yard keeper, and Jason Scott's 12-yard return of John Kohlbrenner's blocked punt.

A stout offensive line was made up of center Connor English, guards Alec Joseph and Bryan Derr, tackles Quinton Derr, C.J. Stehli and Aman Orlena, and tight end Lucas Nina-Boesler.

Quinton Derr has drawn recruiting interest from Monmouth, Stony Brook, Towson, and Villanova. The 6-foot-5, 260-pound senior has shined after missing the second half of last season with a torn anterior cruciate ligament.

Upper Dublin's defense limited the Indians to 36 yards rushing on 23 attempts and 16 passing through three quarters.

Unionville, the defending district champion, rebounded from an 0-3 start to finish with a 6-7 mark.

"I'm just thankful for everything this group gave us," Indians coach Pat Clark said. "In this game, we went up against a team that capitalized on every mistake we made."
