Halak stopped 25 shots for his third shutout of the season and the Blues improved to 6-0-0 at Scottrade Center by beating the San Jose Sharks 2-0 on Thursday night.
Halak, acquired from Montreal during the summer, has been in goal for all six home wins. He's 7-1-1 overall with his new team with a 1.53 goals-against average and .940 save percentage. He built on a brilliant October, when he went 6-1-1 with a 1.71 GAA.
"From the very beginning, we had a game plan and we followed the plan," Halak said after the Blues limited San Jose to a season-low in shots. "Especially in the third period, our guys did a great job coming back, and we stayed disciplined.
"I'm not doing anything special," he said when asked about his hot start. "I'm just trying to do what I can."
Halak made his sixth straight start and was sharp in net, stopping a handful of shorthanded chances. Joe Pavelski shot high off the glass on a breakaway midway through the second and was stopped a break-in later in the period.
"The way Jaro is playing gives us confidence," Perron said. "We feel really confident when he's in net. The best thing is that we play our game. It doesn't matter who we play … we come out and play our own style."
Matt D'Agostini and David Perron scored for the Blues. Perron got his goal after recovering from an elbow to the head by Sharks captain Joe Thornton, who drew a five-minute major and a game misconduct for the hit to the head early in the second period. Alex Pietrangelo assisted on both goals.
"I didn't know if I would be all right or not," Perron said after the game. "I feel fine right now. Fortunately I got to bounce back and score a big goal for us, and we got the win."
Thornton said he didn't think he did anything wrong.
"I felt like I established myself on the ice," the Sharks' captain said. "I just braced myself for the hit. He just ran into me, to be honest with you."
Overall, the Blues have won five in a row and have 16 points in their first 10 games, one point behind the 2002-03 team for the fastest start in franchise history. Going back to last season, they've won 12 in a row at home after struggling at Scottrade Center for the last couple of years.
"For some reason, it's the home of the Blues at the end of the National Anthem," forward David Backes said. "It's a great way to reward our fans the way we haven't the past couple of years."
The Blues extended their franchise record to 12 wins overall in a row at home despite going 0 for 6 on the power play. Most of last season, St. Louis had one of the worst home records in the NHL.
The Sharks were shut out for the second straight game, held to a season-low 25 shots, and haven't scored 144 minutes, 43 seconds. San Jose has been blanked in its last three games on the road for the first time in franchise history.
"It's been kind of all or nothing," Pavelski said. "We have to figure it out. We're offensively challenged right now."
D'Agostini got his fifth of the season at 17:41 of the opening period, beating Antti Niemi from the lower right circle with a shot that went over the goaltender's pad. Perron added an insurance goal at 14:12 of the second.
The only flaw for the Blues was another scoreless night on the power play -- they were 0-for-7 and are in a 3-for-27 slump.
"Not very good," coach Davis Payne said when asked about his power play's lack of production. "Fortunately for us, it wasn't the issue in the game. We were still able to get two goals and win the hockey game."
Niemi, who led Chicago to the Stanley Cup last spring, finished with 25 saves but continues to struggle with his new team. He's now 1-4-0 as a Shark and has seen fellow Finn Antero Niittymaki grab more of the playing time.'
Coach Todd McLellan wants his players to relax.
"We had three breakaways and didn't have any shots on goal," McLellan said. "It's incredible when that happens. We had a couple 2-on-1s where we didn't get a shot on goal. We probably haven't had that many free looks at a net in a game all year."
