BOSTON (Reuters) - Daniel Alfredsson's three goals helped power the Ottawa Senators to a 5-1 win over the Boston Bruins on Monday, giving the team a share of second place in the NHL's North east division.

Alfredsson, in just his second game back after missing the prior 11 with a separated shoulder, scored during the first period to make it 2-0 and completed his hat-trick with a pair of goals in just over a three-minute span midway through the second period.

It marked Ottawa's longest winning streak since November and the team's first victory this season against the Bruins after losing the previous four contests.

Alfredsson has four goals and two assists in two games back from injury. In his first game on Saturday, he scored a goal and had two assists versus Montreal.

Ottawa goalie Brian Elliott blanked the Bruins through the game's first two periods until Daniel Paille scored his sixth of the season just over four minutes into the third period.

Boston's Patrice Bergeron did not register a point in his return to the team's lineup after sitting out two weeks with a broken thumb.

It was a rare weekday afternoon game given the Martin Luther King Jr. Day in the United States.
