It took them awhile, but South Fayette's No. 1-ranked offense finally started clicking in the second half to pace the No. 2 Lions (11-0) to a 31-7 quarterfinal victory against Century Conference rival Seton-LaSalle (8-3) at Peters Township High School.
The No. 10-seeded Rebels jumped on the scoreboard first when Tyler Perone found Malik White in the end zone from 8 yards. But that would be the last time Seton-LaSalle and Perone would celebrate.
The suffocating Lions defense picked off Perone four times.
Jared Walker tied the score at 7-7 in the second on a 1-yard plunge.
It was only a matter of time before Brett Brumbaugh and the offense would erupt, and that's exactly what they did in the third.
Brumbaugh tossed three touchdowns after the break, including an 87-yard strike to Justin Wilson, his second score of the game.
The Lions outgained the Rebels, 545-157.
South Fayette will face Beaver Falls in the semifinals.
