ST. LOUIS -- It's commonplace for the Chicago Blackhawks to see Patrick Kane contribute offensively.
Kane's timely power-play goal late in the second period extended his point streak to 12 games, and Chicago ended a five-game road losing streak with a 4-2 victory against the St. Louis Blues at Scottrade Center on Saturday.
Trevor van Riemsdyk and Kane scored goals 3:38 apart late in the second to erase a 2-1 deficit.
Kane has nine goals and 11 assists during his 12-game point streak, the longest in the NHL this season.
"We're pretty used to [Kane] doing that," said Blackhawks goalie Corey Crawford, who made 29 saves. "That's nothing new from him. He always finds a way to score big goals and he just doesn’t stop."
Andrew Shaw and Artem Anisimov scored for the Blackhawks (9-7-1), who got defensemen Duncan Keith and Michal Rozsival back in the lineup following knee and ankle injuries, respectively.
Keith, who had surgery Oct. 20 to repair a torn meniscus in his right knee, played a game-high 27:34.
"I felt good," Keith said. "It was nice to get back in the swing of things. It was a tough game with a good crowd and a good atmosphere. I thought that we did a lot of good things and battled through some things. We can build off this game."
Chicago had been outscored 19-8 in losing five in a row away from the United Center, but got a gritty victory in a tough Central Division matchup that featured big hits and plenty of emotion from both sides.
"We needed a win on the road," Blackhawks coach Joel Quenneville said. "We know that we want to be known as a team that plays the same way everywhere we play. We didn't want to change how we play. We saw some other lines score for the first time all year, so I think that was the most positive thing we've seen."
Vladimir Tarasenko scored twice for the Blues (11-5-1), who have lost two in a row in regulation for the first time this season. Jake Allen made 23 saves, including a highlight-reel stop of what looked like a sure goal by Marko Dano with 1:43 left in the second period.
The Blues felt they were in control of the game leading 2-1, but saw the Blackhawks get seven of the final eight shots of the second period that turned a 2-1 lead into a 3-2 deficit.
"We were really playing well and we made some critical errors," Blues coach Ken Hitchcock said. "We didn't get a clear once, we took a penalty on the backcheck and then we made a couple mistakes on the penalty kill, didn't get to a loose puck and then we jumped into a pile ... (it's) disappointing.
"If we expect to win, we're going to have to make big plays at the right time. That's what that team's done we played today. They make big plays at the right time. That's why they win championships. If we want a piece of the pie in this division, in this conference, we're going to have to have more people make big plays at the right time."
Keith made an immediate impact for the Blackhawks offensively. They took a 1-0 lead 4:10 into the game after Teuvo Teravainen picked off a Ryan Reaves defensive zone pass and got the puck to Keith, whose shot from the left point went in off Allen's glove after Shaw's tip in front.
Tarasenko went to work for the Blues in the second period. He tied the game 6:32 into the period by following up his own rebound after getting a feed from Alexander Steen.
Tarasenko gave the Blues a 2-1 lead with a power-play goal, the first of the season for the Blues on home ice on their 24th chance. Tarasenko used teammate Troy Brouwer as a screen and beat Crawford from the left circle at 8:16.
But van Riemsdyk tied the game 2-2 with 4:43 left in the second by stepping into a slap shot from the slot, and Kane walked in alone on Allen on Chicago's fourth power play and beat the Blues' goalie five-hole with 1:05 remaining to give the Blackhawks a 3-2 lead with his NHL-leading 12th goal. With 26 points, Kane is tied with Tyler Seguin of the Dallas Stars to lead the League.
Chicago took seven of the final eight shots in the second after being outshot 11-6.
Allen's save came off a virtual 2-on-0 after Alex Pietrangelo gave up the puck behind the net, and the puck eventually wound up on Dano's stick, but Allen came up with the glove save. The play went to a video review and it was determined that the puck didn't cross the goal line.
"The puck squirted out and they had a 2-on-0 in front of the net," Allen said. "Another desperation (save and) a little bit of luck."
Anisimov scored an empty-net goal with 47 seconds remaining after the Blues outshot the Blackhawks 10-3 before the goal.
"It was a [heck of a] hockey game," Hitchcock said. "I want to win those games. I'm sure the players do too. I just don't want to be the team making the big mistakes when the game's on the line. We made big mistakes when we were really moving the game along at a great pace, were really starting to take control and doing the things we wanted to do, we made big errors."
Prior to the game, there was a moment of silence to honor the victims of the attacks in Paris on Friday.
