Dylan Holloway scored for the Blues (9-9-2), who had won two in a row. Joel Hofer made 24 saves.
“We’re getting some looks; we’re just not finding the back of the net,” St. Louis captain Robert Thomas said. “and we’re not creating enough looks. It’s obviously been a struggle lately.”
Brady Tkachuk made it 1-0 at 5:12 of the first period with a power-play goal after the Panthers failed to convert on 39 seconds of 5-on-3. They did convert on the 5-on-4 with a 3-on-2 odd-man rush, finished off by Tkachuk dangling around Blues defenseman Brandon Carlo and beating Hofer from the slot into the top right corner.
Matthew Tkachuk had the secondary assist to give him nine helpers during his streak.
Dmitry Kulikov’s first of the season made it 2-0 at 6:29 on a fluttering shot from the left point that hit the stick of St. Louis defenseman Colton Parayko between Hofer’s pads.
“I think (we needed) to come out to a good start; there hasn’t been too many early leads,” Reinhart said. “We haven’t really been able to play with it for a full 60. That was obviously important.”
Anton Lundell made it 3-0 at 3:28 of the second period following a Blues neutral zone turnover, a Brady Tkachuk shot from the left circle that Hofer stopped, but Lundell was in the slot to put back the rebound.
