Connor Hellebuyck made 44 saves for the Jets. Mike Smith stopped 32 shots for the Oilers.

The Jets were bolstered by the return of Ehlers, who hadn’t played since April 24. He sat out the last 11 games of the regular season with an upper-body injury.

The Oilers jumped out to their most aggressive start of the series, taking their first lead of the series since early in Game 1.
