FOXBORO — On her fourth frantic jump, Calleigh Brady’s tired legs lost their balance.

It took 45 seconds into a double overtime defensive marathon Sunday afternoon for Brady’s shot from the point to sneak through, giving No. 5 King Philip a 2-1 win over Hockomock League rival No. 12 Canton in a Div. 2 girls hockey second round matchup.

Freshman teammate Stephanie Leblanc had beelined toward her, accidentally leaping over the junior as she stumbled. Ella Morgan also missed Brady on her dive to the ice, but caught her by the hips as she slid by. Both Leblanc and Morgan were finally both with Brady as she got to her knees, before 19 other teammates knocked them all over by piling on top of them in celebration.

It was just last year that the Warriors (21-2-1) lost in the tournament’s first round to Canton despite beating it twice in the regular season. Three games into this year, a revitalized and promising group then tragically lost beloved head coach Ken Assad.

Resiliency has been a staple for the tightly-knit Warriors. So far, this win is its pinnacle. And twenty-one teammates piled on top of Brady, after they secured their first state quarterfinal trip, is its lasting image.

“I was just trying to catch my breath, but it was great,” Brady said of the celebration. “We’re all just screaming, I was super excited. … It feels awesome. Obviously everyone’s goal is to go to the Garden. At least that’s our end goal, but we take it game by game.”

Everyone in the arena knew the difficulty of the matchup, a third meeting with a Bulldogs group that knows King Philip better than any other team in the tournament. That showed at every stage, too, with both defenses greatly limiting opportunities.

Canton goalie Charlotte Eagles (27 saves) and Warriors goalie Kiki Lynch (27 saves) took care of the rest in a true battle.

“Defensive struggle all along,” King Philip interim head coach Tim Langevin said. “They hadn’t scored on us all year. I told the girls, I said if we can get one (goal), I know we’re going to win the game. … (But) they’re just so good defensively. It’s just tough, and (Eagles) is a rock.”

Annabelle Curran scored off a rebound in a three-shot frenzy to give King Philip a second-period lead, only for Violet Penders to match it with a shot from the point for a 1-1 tie after two.

Eagles made a couple highlight-reel saves in regulation to keep it that way, including a diving stop to the backdoor on a penalty kill. Lynch, always steady between the pipes, responded with five saves of her own in overtime as Canton ramped up offensive pressure.

“She’s always great,” Brady said. “She made some awesome saves in the third and in overtime.”

After the Bulldogs killed the rest of a power play KP earned in the first overtime, Leblanc fed Brady at the center point for a shot she lobbed into the corner of the net for the winner.

It was just her second career goal.

“I don’t really score that much … so it was pretty cool, especially in a playoff game,” she said.

Of course, Assad was firmly in mind.

“We had a big (pasta) party last night, and all we did was sat there for two and a half hours just telling jokes and laughing about things that he said,” Langevin said. “Somebody’s watching over us. Somebody wants us to win.”
