Bjugstad has one goal and one assist in 13 games for the Penguins (39-23-6), who were third in the Metropolitan Division, five points behind the second-place Philadelphia Flyers and three ahead of the Columbus Blue Jackets, who held the first wild card into the Stanley Cup Playoffs from the Eastern Conference.
