Bobby Ryan scored early in the third period, Craig Anderson stopped 22 shots and the Ottawa Senators beat the Boston Bruins 1-0 on Wednesday night for a 3-1 lead in their first-round playoff series.

It was Anderson's fourth career playoff shutout.

Tuukka Rask made 26 saves for Boston, which had a goal disallowed in the second when Ottawa coach Guy Boucher challenged and the replay showed Noel Acciari was offsides.

The Bruins, who were winless in four games against the Senators in the regular season, will try to force the series back to Boston with a victory in Ottawa in Game 5 on Friday night.
