TORONTO, Canada — Frederik Andersen made 32 saves as the Maple Leafs battled to a series-leveling 3-1 win over the Boston Bruins on a night of raw emotion following the deadly van attack in Toronto.

Just hours after the van rampage left at least 10 people dead, game six got under way in a somber atmosphere at the Air Canada Centre with a moment of silence to honor the victims.

Trailing 3-2 in the best-of-seven series, Toronto needed to win to force a decisive game seven in Boston on Wednesday. The Bruins however were determined to claim the win they needed to advance, and took the lead in the second period with a goal from Jake DeBrusk.

But Toronto hit back through William Nylander and Mitchell Marner to take a 2-1 lead at the end of the second before Tomas Plekanec added a third in the final period to complete the scoring.

In the night's other game, the Washington Capitals booked their place in the Eastern Conference playoffs second round with a decisive 6-3 win over the Columbus Blue Jackets to complete a 4-2 series triumph.

Two second-period goals from Capitals star Alex Ovechkin proved decisive, handing Washington a 3-1 lead after the Blue Jackets' Nick Foligno had cancelled out Dmitry Orlov's opener for the Caps.

Pierre-Luc Dubois pulled one back for Columbus early in the third period but goals from Devante Smith-Pelly and Chandler Stephenson put Washington 5-2 ahead.

Foligno grabbed his second goal of the night to reduce the deficit but Lars Eller steered home Washington's sixth into an empty net to complete an emphatic win.

Barzal headlines Calder finalists

The NHL announced the finalists for the Calder Trophy, the award given to the league's top rookie — who this season could be the biggest runaway winner of all the awards. The three finalists tabbed Sunday are Mathew Barzal of the New York Islanders, Brock Boeser of the Vancouver Canucks and Clayton Keller of the Arizona Coyotes.

Boeser, the 23rd overall pick in the 2015 draft, finished second among rookies with 29 goals this season despite missing 20 games. Keller, the youngest of the three finalists at 19 years old and the No. 7 pick in 2016, played in all 82 games. His 65 points were the most by a Coyotes rookie since the franchise relocated from Winnipeg to Arizona in 1996.

But the favorite to win the award in the eyes of most is Barzal. The No. 16 pick in 2015 also played in 82 games. And while his 22 goals were only sixth among rookies, he far outpaced the field in numerous measures and accomplishments:

— His 63 assists were 21 more than the next-closest rookie, and his 85 points cleared runner-up Keller by 20.

— He is the seventh rookie in NHL history with at least 20 goals and 60 assists — and the first since Sidney Crosby 12 seasons ago.

— He is the second rookie ever to collect three five-point games -- the other was Montreal's Joe Malone in 1917-18 ... the inaugural season of the NHL.

The winner will be announced at the 2018 NHL Awards show in Las Vegas on June 20. — Agencies
