Kelley Steadman had a natural hat trick and Genevieve Lacasse made 40 saves as the Boston Blades won their first Clarkson Cup title by defeating the defending champion Montreal Stars 5-2 on Saturday.

Jen Schoullis scored the other two goals for Boston, which scored four power-play goals on nine opportunities. Kacey Bellamy added three assists for the Blades.

Dominique Thibault and Meghan Agosta-Marciano scored the Stars, who tied the game in the second before Steadman took over. Montreal struggled on the power play, going 0-for-7.

Schoullis opened the scoring midway through the first period on a power play when she tipped in a shot from the point by Bellamy.

The Blades padded their lead in the second period when they capitalized on another power-play opportunity. Just eight seconds after the Stars' Caroline Ouellette incurred a tripping infraction, Schoullis scored her second goal of the game after depositing a loose rebound while parked in front of the net.

The Stars got on the scoreboard just 32 seconds later when Agosta-Marciano delivered a low wrist shot from the slot area that eluded Lacasse.

Montreal tied the game just before the midway point of the period on a goal by Thibault.

But with the Stars' Catherine Ward whistled off for roughing just before the midway point, the Blades' power play rose to the occasion once again when Steadman scored the go-ahead goal to give Boston a 3-2 lead entering the third period.

Pressing for the equalizer, the Stars had several good scoring opportunities that included two, two-man advantages.

But the Blades' penalty killing units combined with clutch net minding by Lacasse, thwarted off any scoring chances the Stars could mount.

With the Stars trying to fend off a double minor infraction by Haley Irwin late in regulation time, the Blades scored their fourth power-play goal when Steadman scored.

The Blades rounded out the scoring when Steadman fired the puck into an empty net with 56 seconds remaining.

Stars netminder Charline Labonte finished with 29 saves.
