Maggie Malloy didn’t need any help in overtime for the Canton girls’ hockey team.
The junior forward won a loose puck in the neutral zone and beat the entire Milton defense for the unassisted overtime winner as the No. 12 Bulldogs climbed back from two deficits for a 3-2 win in the Canton Ice House Invitational championship on Saturday night.
Malloy’s efforts earned her MVP honors.
“She’s such a competitive athlete,” said Canton coach Dennis Aldrich. “What she just did there, that’s what she does in practice every day. She’s very explosive . . . Once she made that cut though, she’s got that glow in her eyes. As well as their goalie was playing, I thought it was done.”
Even though the host Bulldogs (3-0-3) won the tournament, the game was recorded as a tie for MIAA purposes.
The No. 15 Wildcats (4-0-3) opened the scoring while on the penalty kill with 6:24 left in the opening period, as Julia Scannell fed Kat Buchanan with a perfect entry pass for a shorthanded goal past Colleen Kelleher (15 saves).
The Bulldogs got one back more than two minutes into the second period, as freshman Maria Femia finished off a two-on-one opportunity for her first career goal.
Milton reclaimed the lead right before the buzzer, as Scannell forced a turnover on the backcheck and took the puck coast-to-coast for a 2-1 lead with 37.5 seconds left in the period.
Canton continued to pepper Milton freshman netminder Maeve Corcoran (25 saves) with shots, finally breaking through with 5:58 left in the third when a Leah McClellan wrister from the blue line beat her between the padsto tie the game, 2-2.
The teams traded chances in overtime before Malloy’s heroics gave Canton the win.
“[Milton] took us out of our game a little bit, but to be able to fight through that and get to that point, we just never quit,” said Aldrich. “And it showed up last year. It got us to the Garden last year . . . I don’t think pressure situations get to them too much.
“I will never doubt them. It’s a real character-building win.”
