Boyd rushed for 227 yards and five touchdowns in a 53-0 win against Berlin Brothersvalley in a PIAA Class A quarterfinal Friday night at Somerset High School.
Boyd became the WPIAL's all-time career touchdown leader with 114, and Clairton extended its state-record winning streak to 61 games by defeating the District 5 champions.
"It means a lot to me," said Boyd, who broke the record of 110 touchdowns set by Hopewell's Rushel Shell from 2008-11. "It feels sort of like the game we broke the record with 60 wins. Rushel Shell is one of the greatest players in the [history of the] WPIAL. This is great for me."
With 5,529 rushing yards, Boyd moved into sixth on the all-time WPIAL rushing list.
"You just don't see any kids like that in our league or any conference around here," Berlin Brothersvalley coach Doug Paul said. "He's phenomenal. He's a great player. He's the best I've ever coached against, and I've coached [current Arizona Cardinal running back] LaRod Stephens-Howling in an all-star game."
Clairton is 14-0 and will play District 9 Port Allegany, 28-21 winners of a quarterfinal game against District 10 Sharpsville Friday night, in the semifinals.
Port Allegany (13-0) features quarterback Matt Bodamer, the WPIAL's all-time leader in career passing yards.
Berlin Brothersvalley closed an 11-2 season and entered the game as decided underdogs. Clairton has outscored District 5 opponents by a combined 221-0 in the past five playoff games involving the two districts.
Still, Berlin Brothersvalley trailed only 6-0 after one quarter.
"The first quarter, we played them tough. We were able to get first downs and we moved the ball, but at the same time, we weren't able to finish," Paul said.
Clairton lost Pitt recruit Titus Howard to a second-quarter injury which led to a long delay.
"It looks like a dislocated elbow," Clairton coach Tom Nola said. "Senior year. He's one of our best players."
"We need him back," Boyd said. "He's a big part of our team."
Clairton broke open the game with 20 points in the second quarter and three more touchdowns in the third quarter.
The Bears netted 270 rushing yards and Armani Ford passed for 124 yards to put Clairton at 394 total offensive yards.
Boyd had his team's first four touchdowns on runs of 17, 1, 19 and 8 yards.
Terrish Webb caught a 10-yard touchdown pass from Ford, who also had a 3-yard scoring run.
Boyd broke a 78-yard touchdown in the third quarter.
"Definitely, speed is a great role in our team," Boyd said. "We have great speed and a whole bunch of athletes, but without the line and any type of blocking, we wouldn't be successful."
Damond Flowers returned a fumble recovery 40 yards for the game's final score.
Berlin Brothersvalley senior running back Drew Glotfelty rushed for a team-high 79 yards on 22 carries and finished the season with 2,012 rushing yards.
"Drew is our leader," Paul said. "The problem is with Clairton is they've got 15 Drews. Well, maybe not 15. But they have two or three like that."
