BOSTON (AP) — Fabian Zetterlund scored two goals, Tim Stutzle and Dylan Cozens scored 19 seconds apart in the second period and the Ottawa Senators beat the Boston Bruins 6-2 on Sunday night for their fourth straight victory.

Drake Batherson and Claude Giroux each had a goal in the first when the Senators opened a quick 3-0 edge. Batherson and Cozens each had two assists and former Bruins goalie Linus Ullmark made 17 saves in a game that ended with a few late scraps.
