Chicago, IL (SportsNetwork.com) - Patrick Sharp scored the go-ahead goal in the final minute of the second period and Marcus Kruger found the net in the first minute of the third to lift the Chicago Blackhawks to a 4-2 victory over the St. Louis Blues on Sunday.
Jeremy Morin also scored and added an assist for the Blackhawks, who have won three straight after a three-game skid and pulled within two points of Colorado for second place in the Central Division. The Avalanche earned a point with a shootout loss to Pittsburgh later Sunday.
"Very workmanlike three games in a row and we got rewarded each night," said Chicago head coach Joel Quenneville. "It was a good week for us and I liked our response to a real tough week prior."
Corey Crawford stopped 21 shots in the victory and Ben Smith scored into an empty net in the final seconds.
Brian Elliott made 31 saves for St. Louis, which was coming off a 4-0 loss to Colorado on Saturday but still sits on top in the Western Conference. The Blues, however, remained two points behind idle Boston in the Presidents' Trophy race.
Jaden Schwartz and Vladimir Sobotka scored for the Blues, who will close the season with four games in six days, starting Tuesday against Washington.
"We're a little bit tired," said Blues coach Ken Hitchcock. "We still have four more games to play. We have a lot of hockey to play yet and have to find a way to re-energize ourselves and get back to work."
The game appeared to be headed toward the third period in a 1-1 tie, but Andrew Shaw slipped the puck to Morin for a 2-on-1 in the final minute. Morin sent a pass to Sharp in the left circle and he blistered a shot past Elliott for his 33rd goal with 26.2 seconds left to put Chicago in front.
"Those are obviously momentum swings that can take a game in the opposite direction," said Elliott about the late second-period goal. "We had the opportunity to come back, but weren't able to do it."
The Blackhawks added to their lead just 56 seconds into the third. Joakim Nordstrom fired a shot from the right circle that caromed off the right post, hit the back of Elliott and tapped the left post. Kruger was on the spot in the crease to quickly swipe the puck into the net for his eighth goal.
Sobotka beat Crawford with a shot from the left circle for his ninth goal of the season with 2:02 remaining to pull St. Louis within one, but the Blues were unable to net the equalizer with an extra attacker.
Alex Pietrangelo's stick broke as he was attempting a shot from the right point in the closing seconds and the flub led to an empty-net goal for Smith with 3.3 seconds left to seal it.
Schwartz gave the Blues the early lead just 1:57 into the contest on a power play when his second shot from the left circle made its way through traffic for his 24th goal.
Morin tied it for Chicago at 8:34 of the second when he flipped home the rebound of a Bryan Bickell shot from the left circle.
