Kris Letang scored a power-play goal and had an assist in his return from an upper-body injury, Matthew Murray stopped 32 shots in his season debut, and the Pittsburgh Penguins defeated the Anaheim Ducks 5-1 on Wednesday night.

Patrick Hornqvist, Bryan Rust, Matt Cullen and Evgeni Malkin also scored for the Penguins, who improved to 7-2-1 despite not having Murray to start the season after breaking his hand during the World Cup of Hockey.

Malkin put the Penguins ahead 7:41 into the first period, scoring his sixth goal of the season.

Cullen scored 2:33 later to give the Penguins a 2-0 lead on his 40th birthday. The Ducks challenged that Tom Sestito was offside when playing a long pass from Eric Fehr before setting up Cullen, but video review was inconclusive and the play stood as called.
