Marian Hossa had a goal and an assist, and Chicago's Joel Quenneville became the 10th coach to earn 600 NHL victories as the Blackhawks beat the Calgary Flames 4-2 on Sunday night for their fifth straight win.

Steve Montador, Niklas Hjalmarsson and Patrick Kane also scored for the Blackhawks, who got 22 saves from Ray Emery.

Chicago vaulted past Minnesota into first place in the NHL standings with a league-leading 46 points. The Blackhawks are 7-0-1 in their last eight games.

Calgary's Olli Jokinen and Curtis Glencross scored power-play goals in the third period, and both had an assist. Miikka Kiprusoff made 21 saves.

Emery, who has taken over for struggling No. 1 goalie Corey Crawford, started and won for the fifth straight game while improving to 9-1-2 overall. He has played in seven straight, including six starts.

Crawford hasn't played since a start on Dec. 5 against Phoenix when he was pulled early in the second period after allowing three goals on 16 shots.

Blackhawks defenseman Brent Seabrook sustained an undisclosed upper body injury late in the first period and didn't return.

The Flames finished a four-game road trip at 0-2-2. The Blackhawks have won eight straight at home against Calgary, dating to a loss in March 2008.

Montador scored at 9:23 for the only goal in the first period. After the Blackhawks had controlled the puck in the Calgary zone for a nearly a minute, Montador fired in a low shot from the top of the right circle.

With 4:35 left in the first, Seabrook was slammed headfirst into the glass from behind by Flames forward Rene Bourque, who received a major penalty for boarding and was ejected. He remained on the ice face down for a minute before he was helped up and skated to the bench on his own.

The Blackhawks failed to capitalize on the ensuing power play.

Hjalmarsson made it 2-0 at 5:15 of the second with his first goal of the season. He took a pass at the top of the slot and fired a shot through a screen in front of Kiprusoff. The puck hit traffic and curled slowly into the net.

Kane's power-play goal with 5:05 left in the second extended Chicago's lead to 3-0. Kane moved in on right wing and beat Kiprusoff with a high screened shot from the slot.

Jokinen cut it to 3-1 with a power-play goal at 2:35 of the third, but Hossa restored Chicago's three-goal edge during a 5-on-3 power play midway through the period.

Glencross completed the scoring with a power-play goal with 3:35 left on a rebound of his own shot.

NOTES: Chicago's Patrick Sharp had an assist to run his career-high point streak to nine games. ... Flames C Matt Stajan left the game late in the second period with an ankle injury and didn't return. Chicago LW Dan Carcillo sat out a second game with an undisclosed upper body injury. Both are day-to-day. Blackhawks LW Jeremy Morin played after being recalled from Rockford of the AHL earlier Sunday. Flames captain Jarome Iginla, who has 496 NHL goals, was held to one point.
