It appears the Andrew Hammond era for Ottawa as a starting goaltender is all but over, which is not necessarily a bad situation for the Senators in this context.
Craig Anderson unofficially reclaimed his starting job with a 28-save performance to stave off elimination for the Sens in a 1-0 shutout win over the Montreal Canadiens. Anderson started Game 3 and stopped 47 of 49 Montreal shots on goal in an overtime loss, but it was still sort of in question as to whether he would start Wednesday.
The series is now at 3-1 in favor of Montreal.
