ST. LOUIS -- Alex Pietrangelo scored twice for the St. Louis Blues in a 6-4 win against the Toronto Maple Leafs at Scottrade Center on Saturday.
Vladimir Tarasenko, Joel Edmundson, Magnus Paajarvi and Vladimir Sobotka scored, Brayden Schenn had four assists, and Jaden Schwartz three assists for the Blues (11-3-1), who are 6-1-0 at home and 7-1-1 the past nine games.

St. Louis scored twice in the second period to take a 3-1 lead.
"We got in on the forecheck," Pietrangelo said. "Their [defensemen] want to be mobile and want to be up the ice and skate. I think the way our forwards were forechecking on their guys, it kind of limits the opportunities for them to get in there."
Jake Allen made 27 saves for St. Louis and is 11-2-1 in his past 14 home starts.
"I think we just had a little more bite to our game [in the second period]," Schwartz said. "In the first, we had chances, but I think we were on the outside a lot. We got pucks to the net in the second and just kept rolling over the lines. We were playing with speed, we were going north with the puck, and that allowed us to play in their zone a little bit more and create some opportunities that way. It was a good push and we kind of rolled with the momentum."

The Maple Leafs (8-7-0), who went 1-3-0 on a four-game road trip, have lost six of eight.
Tyler Bozak scored twice, Andreas Borgman had a goal and an assist, Connor Brown scored, and Matt Martin had three assists for the Maple Leafs. Frederik Andersen made 26 saves.
"We had a tough trip and played good teams and all that, but obviously we're not in a situation that we're handling this very well," Toronto coach Mike Babcock said. "So we're not playing good enough, and like I said, get ourselves regrouped. We've got to be [ready] against a team that seems to win every night in their building here."
Borgman, who took Martin's feed inside the blue line, skated into the right circle and beat Allen with a wrist shot high stick side at 9:16 of the first period to give Toronto a 1-0 lead.
Tarasenko tied it 1-1 on a rebound goal at 2:33 of the second period. Edmundson put the Blues ahead 2-1 with another rebound goal, this time from the left of Andersen, at 7:10.

Pietrangelo put the Blues up 3-1 at 10:28, taking Schenn's pass and faking a shot on Andersen before curling to the goal line and tucking a backhand inside the near post.
The teams scored three times in 1:02 early in the third and six times in the period.
Paajarvi made it 4-1 at 1:22, Bozak got it to 4-2 at 2:07, and Sobotka scored at 2:24 to make it 5-2.
Pietrangelo's power-play goal at 7:52 made it 6-2, Brown made it 6-3 at 10:10, and Bozak scored his second at 13:13 for the 6-4 final.

They said it
"I just think we changed it over a little bit, and I also thought they had a little more jump in the second than they did in the first, and you've got to give them credit. They are a really good team and their top two lines are as good as any team's in the League. I think they play hard, they play physical and they work hard, so they're a tough team to play against." -- Maple Leafs center Tyler Bozak

"In video games when I was younger." -- Blues defenseman Alex Pietrangelo on if he ever scored a goal like his first one
"Working for each other, using one another, that's when we're most effective. Using all three (forwards), all five guys on the ice and moving the puck and moving our feet. We were able to generate some offensive-zone time." -- Blues center Brayden Schenn
