While this might have been the worst defensive game of the five since Joe Sacco took over at interim coach, the Bruins’ goal-scoring woes remain their most troublesome issue. They got 33 shots, including 13 in the third period.

Only 48 hours after rolling up a season-high six goals in a 6-3 win on Long Island, the Bruins offense managed one goal, by Charlie Coyle in the first period.

BOSTON -- Philip Tomasino scored the go-ahead goal in the third period for the Pittsburgh Penguins in a 2-1 win against the Boston Bruins at TD Garden on Friday. Tomasino gave the Penguins a 2-1 lead at 7:26 of the third, slipping the puck under Jeremy Swayman ’s left pad in the low slot.

The Pittsburgh Penguins were spearheaded from strong play in net from Tristan Jarry, as they beat the Boston Bruins 2-1 on Nov. 29.
