The Carolina Hurricanes, though, may threaten their streak now that it appears their starting netminder has returned to his elite form.
The Senators will try to win their fourth straight on their home ice on Thursday night when they host the Hurricanes, who look to beat Ottawa for the second time this month.
After allowing nine goals in his first eight games, Anderson gave up more than two goals for the first time this season in Ottawa's 4-3 win over Buffalo on Tuesday.
"Overall I think this could have been a 4-1 game but it was unfortunate that Buffalo got some lucky bounces and they ended up in the back of the net," said Anderson, who leads the NHL with a .956 save percentage and ranks near the top of the NHL in wins (6) and goals-against average (1.33).
Now the netminder gets a rematch against a Carolina team that beat him 1-0 last Friday despite a season-high 34 saves. Anderson is winless in his last three starts against the Hurricanes despite a 1.67 GAA.
The Senators hope to give Anderson more support this time at home, where they're 4-0-1 while outscoring opponents 17-7.
With center Jason Spezza out following back surgery, the Senators have utilized a balanced attack offensively. Nine players have at least two goals, with Karlsson and Kyle Turris leading the team at four goals apiece.
Turris, however, hasn't scored in his last six games. Karlsson's goal Tuesday was his first in six games, and the Norris Trophy winner has one in his past nine against the Hurricanes.
The Senators may be able to get something going on the power play against the Hurricanes, who rank near the bottom of the Eastern Conference in penalty kill percentage (73.7). Ottawa has converted 4 of 11 chances over its last three home games.
While Dan Ellis stopped 33 shots en route to the shutout win in the first meeting, Carolina goalie Cam Ward is expected to get the start in this meeting.
Ward has allowed one goal while winning each of his last two starts against the Senators.
After allowing 15 goals in losing three of his first four starts, the veteran finished with 41 saves in a 4-1 win at Toronto on Monday.
"I felt really comfortable at the start of the game," said Ward. "I expected they were going to throw a lot of shots at the net, and I had to be ready."
