Highlights of Sunday's NHL games

Senators 3, Bruins 2 (overtime)

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 as Ottawa won their first-round playoff series with Boston in Game Six.

The Senators will play the New York Rangers in the second round of the Eastern Conference playoffs.

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 Boston's TD Garden.

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.

Rask made 26 saves for the Bruins.
