ST. LOUIS -- The St. Louis Blues tied their record with their ninth straight win at home, 4-1 against the Anaheim Ducks at Enterprise Center on Monday.
Jake Allen made 20 saves for the Blues (30-10-7), who have won four games in a row and matched their longest home winning streak, set from Jan. 26-Feb. 26, 1991.
St. Louis has the most home wins in the NHL (17-4-3).
"We've been going pretty good," said Jaden Schwartz, whose second-period goal put the Blues ahead by two. "It's tough to keep track when you play on the road, so it's not something you really think about, but we're finding different ways to win, and each night, different lines, different guys are chipping in, whether it's offensively or defensively. Both goalies are kicking. Doing the little things right, playing well as a team."

John Gibson made 30 saves for the Ducks (17-24-5), who have lost four in a row and are 1-6-1 in their past eight games.
"To have confidence, to earn confidence, you have to play well and do things right on a regular basis, and it's hard to get that momentum and gather that confidence when you shoot yourself in the foot or a bounce doesn't go your way," Anaheim captain Ryan Getzlaf said. "... We're not getting timely goals right now, and it makes it even more of a struggle when you're trying to get things going."
The Blues scored twice on 22 shots in the second period.
Tyler Bozak put them ahead 2-1 at 2:21. After Robert Thomas stole the puck from Max Comtois in the Ducks zone, Bozak scored off a pass from Mackenzie MacEachern.
Schwartz scored seven seconds into a 4-on-3 power play to make it 3-1 at 9:41. After Ducks defenseman Josh Manson and Blues forward David Perron each was called for unsportsmanlike conduct at 7:49, Anaheim's Max Jones was called for hooking Ryan O'Reilly at 9:34.

"We talked and came out in the second period, we played our game," St. Louis coach Craig Berube said. "We just quick-upped pucks and got it in and went to work and just kind of wore them down. That's what I saw. Line after line, and everybody was doing the same thing and doing a good job."
Ivan Barbashev scored unassisted to make it 4-1 at 10:29 of the third period following a mishap by the Ducks behind their net. Defenseman Hampus Lindholm collided with Gibson as the goalie attempted to leave him the puck, and Barbashev pulled it to the front and put in a backhand.
Anaheim has been outscored 15-6 during its losing streak.
"You know you have to be on your 'A' game," Ducks forward Adam Henrique said. "That's every single night no matter who you're playing. Every team in this league is good, and if you're not on your game, they're that much better, or it seems that way."
Alexander Steen scored his third goal in three games to give the Blues a 1-0 lead at 7:53 of the first period on a slap shot from a sharp angle.

They said it
"Let's not forget who we are playing. We're playing the Stanley Cup champions and a team that does trust their system, and they rarely stray from it. That's where we have to aspire to get to, and I think there's great lessons here tonight." -- Ducks coach Dallas Eakins
"I think we just came in (after the first period) and said we've got to hold on to the puck a little bit longer. And I thought the guys did a [heck of a] job the rest of the game controlling the puck, controlling the play. Smart decisions, putting pucks behind the net when need be, and that's how we create our chances." -- Blues goalie Jake Allen
