Roslovic scored a pair of goals, including the overtime winner, in Tuesday's 7-6 victory over the Capitals.
Roslovic picked up a power-play goal in the second period before scoring the game-winner in overtime, one-timing a feed from Johnny Gaudreau on the odd-man rush. The two-goal game snaps a streak of six contests without a tally for Roslovic. The 26-year-old forward is up to nine goals and 29 assists through 67 appearances this season.
