Fowler tied it 1-1 with 18 seconds left in the first after his shot from the top of the left circle caromed off Blues defenseman Nick Leddy's leg. The Ducks had two power-play opportunities in the third prior to Faulk's go-ahead goal and failed to convert, getting three shots on goal.
"At some point, you need to start getting the results," Fowler said. "We can look at the positives as best as we can, but our power play had the chance to put the game away, a couple opportunities and we didn't get the job done and they did. That's the hockey game. There's still a lot of areas in the game where we can still be better."
Acciari scored an empty-net goal with 19 seconds remaining in the third for the 3-1 final.
"I think it's just good to feel that success," Binnington said. "We've got to just keep working hard and keep our head down. It's good to get some wins for sure."
