David Pastrnak had two goals, including his first career made penalty shot, and the Boston Bruins blew past the Pittsburgh Penguins 5-1 on Wednesday night.

Pastrnak, a 19-year-old Czech, was all over the ice in the first two periods, and said he thinks he is starting to find his game in his second year after scoring 10 goals in 46 games last season. The Bruins' 2014 first-round pick now has eight goals in 29 appearances.

Tuukka Rask made 41 saves for the Bruins. Jimmy Hayes, Landon Ferraro and Brad Marchand also scored.

Bruins forward Ryan Spooner had an assist.
