The Red Wings had two breakaways in the period, but Jake Walman shot over the net in the first minute, and Bobrovsky made a blocker save against Adam Erne at 13:55.
Walman later hit the post, and Bobrovsky made three point-blank saves on Dylan Larkin and Lucas Raymond in the first minute of the third period.
"[Bobrovsky] stole the game," Lalonde said. "He was the First Star, Second Star and Third Star. He made some unbelievable saves on the breakaways and the shots from the edge of the crease. After that, you're wondering how it isn't 2-2."
Ekblad extended Florida's lead to 3-1 at 8:11 of the third after knocking in a rebound. It was the fifth multigoal game of his career and the second time he had scored twice on the power play.
Fabbri, playing his second game after missing 10 months with a knee injury, scored at 16:17 for the 3-2 final.
