PITTSBURGH — Frank Vatrano had three goals for his first career hat trick, Patrice Bergeron scored twice, and the Bruins beat the Penguins 6-2 Friday night to sweep the teams' home-and-home series.
Loui Eriksson also scored for Boston, which is 4-0-1 in its past five games and 10-1-3 in its past 14.
Conor Sheary — Vatrano's college teammate at UMass — got his first two NHL points with a goal and an assist for Pittsburgh, and Trevor Daley scored his first goal with the Penguins, who are 0-3-0 since Mike Sullivan replaced Mike Johnston as coach last weekend.
Overall, Pittsburgh has lost four in a row (0-3-1) and six of its past seven to sit 12th in the Eastern Conference.
Sidney Crosby had two assists for the Penguins to break a three-game point-scoring drought.
Sheary, who made his league debut Wednesday and was playing on Pittsburgh's top line, made it 1-0 at 8:20 of the first period. From the left hash marks, he took a feed from behind the net from Crosby and one-timed it past Boston goalie Tuukka Rask. Rask had a personal shutout streak against Pittsburgh stopped at 150:29.
It was the Penguins' first lead in four games, but the Bruins tied it 1:43 later and did not trail again.
After Sheary was tripped by Boston's Kevan Miller, the Penguins gave up a short-handed goal 1:03 into the second period for a 2-1 Boston lead. With Pittsburgh hemmed in in its end, Bergeron was in the low slot and lifted the puck over Jeff Zatkoff's right pad.
Five seconds after that Penguins power play expired, Daley tied it 2-2 with his first goal this season and first since Pittsburgh acquired him this week in a trade with Chicago. He scored from the right point with Chris Kunitz screening Rask.
Boston regained the lead at 3-2 with a power-play goal at 9:39 of the second period when Eriksson got three whacks at the puck from the top of the crease and put the last one under Zatkoff.
During 4-on-4 play, the Bruins' Zdeno Chara sent a shot from the right point over the net. The puck bounced off of the glass and back to the front of the net, where Bergeron swatted it in for a 4-2 lead 35 seconds into the third period.
Zatkoff finished with 28 saves.
Game highlights: Roberto Luongo made 24 saves, Willie Mitchell scored 4:09 into the third period and the Panthers beat the host Hurricanes 2-0 for their third straight win. Luongo recorded his 70th career shutout and moved within one of tying for 11th on the league's all-time list, Elias Sports said.
