BOSTON -- Clarke MacArthur, who fought a two-year battle with concussions to come back to the NHL, scored on a power-play rebound 6:30 into overtime to give the Ottawa Senators a 3-2 victory over the Boston Bruins on Sunday and a six-game series win.
The Senators advance to play the New York Rangers in the second round of the Eastern Conference playoffs after finishing off the Bruins in the best-of-seven series.
MacArthur, who earlier in the series celebrated his comeback with his first goal in two years, sent a Bobby Ryan rebound past Tuukka Rask for the winner.
All six games of the series were decided by one goal, four in overtime, and Sunday marked the Senators' sixth straight win at TD Garden. Ottawa won eight of 10 games against Boston this season.
Craig Anderson made 28 saves for the win.
Ryan and Kyle Turris also scored for the Senators.
Drew Stafford and Patrice Bergeron tallied for the Bruins, with Brad Marchand assisting on both goals. Marchand scored just one goal in the series and has one in his last 26 playoff games, greatly contributing to the first-round loss.
Rask made 26 saves.
The Bruins scored their first first-period goal -- also scoring first for the first time in the series -- when Stafford converted on a power-play slapper with 1:47 left in the period.
The Senators struck twice in the second period.
On the power play, Derick Brassard's slapper from the right point deflected off Ryan at 3:26 -- and Turris then took a pass from Ryan Dzingel and beat Rask with a perfectly place wrist shot at 8:32.
However, early in the third period, Anderson couldn't hold onto a Marchand wrist shot. Bergeron fought off defenseman Cody Ceci to jam home his second of the playoffs at 1:57 to knot the game 2-2.
NOTES: According to STATS, Inc., the three delay-of-game penalties on the Bruins marked the first time since 1989-90 a team did it three times in a first period, the fourth time it was done in any period. The Pittsburgh Penguins had three in a span of 2:02 in the third period of a playoff game last season. ... Bruins C David Krejci was out with a lower-body injury sustained in Game 5. He was limited to only two full games in the series. LW Matt Beleskey was back in for his third game in the series. ... D Chris Wideman, who injured Krejci in a collision, was also injured but was listed as a healthy scratch. D Fredrik Claesson dressed for the second time in the series. ... Ottawa LW Viktor Stalberg, a game-time decision after the skate, dressed, as did Tommy Wingels, in for his second game. LW Tom Pyatt and D Mark Borowiecki remained out with injuries.
