Watertown triumphed in its first football playoff game in decades (if not ever) by defeating host Triton Regional Friday night.
A new football playoff system started by the MIAA this year allowed the Raiders to play in the state tourney.
Triton led at half time 8-7, but in the second half the Raiders offense got into gear.
Mike Petrillo scored two rushing touchdowns - one in the third and one in the fourth to take a 21-15 lead, according to the Boston Globe report. Nick Giordano's second touchdown pass of the game increased the lead to 13, but Triton got within six points.
Watertown stretched the lead with an Erik Antonellis 22-yard field goal, according to the Watertown Sports Twitter account.
Watertown had not qualified for the football playoffs since at least the 1970s, according to Athletic Director Michael Lahiff, and even then, he has heard conflicting accounts of whether the Raiders made the tourney.
Watertown moves on in the MIAA Div. 4 North playoffs and will play the winner of the game between top seed Pentucket and eighth seed Hamilton-Wenham.
