Smith scored a power-play goal and added an assist in Tuesday's 6-3 win over the Kings.
Smith's power-play tally began a wild first-period sequence that saw the teams combine for four goals in a 1:16 span. His helper came later in the same span, as Smith helped Jonathan Marchessault give the Golden Knights a 3-1 lead. Smith has heated up recently with six points in his last six games.
