Philip Tomasino scored his first goal of the season in the third period to lift the Pittsburgh Penguins to a 2-1 victory over the Boston Bruins on Friday at TD Garden.

Boston struck early in the opening period to take the initial lead. Charlie Coyle beat Tristan Jarry with an even-strength wrist shot just 1:24 into the contest, assisted by Trent Frederic and Tyler Johnson. Pittsburgh answered back with one second remaining in the middle frame when Rickard Rakell snapped in his ninth goal of the season off assists from Sidney Crosby and Erik Karlsson.

The Penguins completed the comeback midway through the final frame. Tomasino beat Jeremy Swayman with a wrist shot at 7:26 of the third period, set up by Evgeni Malkin. Pittsburgh held firm for the remainder of regulation to protect the one-goal edge.

Jarry turned aside 30 of 31 shots to earn the victory for Pittsburgh. Swayman stopped 34 of 36 shots in the loss for Boston as Pittsburgh finished with a 36-31 advantage in shots on goal. Neither team capitalized on special teams, with the Penguins going 0-for-2 on the power play and the Bruins finishing 0-for-3.

The win moved Pittsburgh to a 9-12-4 record and extended their winning streak to two games. Boston fell to 11-11-3 on the season with the loss in the first meeting between the two clubs this year.
