Chris Wideman got his first two goals in nearly a year, Craig Anderson made 36 saves and the Ottawa Senators beat the Los Angeles Kings 5-1 on Saturday.
Wideman tore a hamstring last November and missed the rest of the season. The 28-year-old had been without a point in his first four games this season.
Los Angeles' Jack Campbell made his fourth consecutive start and allowed four goals on 11 shots before being replaced by Peter Budaj. Budaj allowed one goal on 11 shots.
Tierney opened the scoring just over six minutes in by tipping Dylan DeMelo's shot past Campbell.
