Holloway made it 2-0 at 6:23, three seconds after a Blues power play expired, with a wrist shot from the right circle.
Holloway extended it to 3-0 at 16:05 from the slot, chopping at a loose puck off Colton Parayko's one-timer from the left point. It was the first time this season St. Louis has scored three goals in the first period.
Holloway has four points (two goals, two assists) the past two games.
"Sometimes things click. I'm just going to keep working like I always do," Holloway said. "I'm feeling good about my game right now. I'm trying to stay confident, but at the same time, I have to have a short memory. You never want to get too high or too low."
The Devils outshot the Blues 24-10 over the final two periods, including 11-1 in the second, but couldn't solve Binnington.
"It was pressure but couldn't find a way to get one," New Jersey forward Stefan Noesen said. "Probably just not hard enough in those areas. ... When things aren't going the way you want, you've got to find other ways to score."
Said Montgomery of Binnington: “(He) held down the fort (in the second period) while we were struggling. But the positive out of that is, it was very obvious where we needed to get better and what we needed to continue to do well."
Buchnevich left at 7:06 of the second period favoring his right leg and did not return.
Montgomery had no update after the game, saying, "I think it's day to day, but I don't have anything."
NOTES: Along with Thomas, Rob Ramage (Jan. 24, 1987) and Andy McDonald (Nov. 11, 2010) also scored in nine seconds to start the game for the Blues. Greg Paslawski (Oct. 29, 1985) and Alexander Steen (March 16, 2010) hold the record of eight seconds. … New Jersey was shut out for the fourth time this season and second time in the past four home games.
