BUFFALO, N.Y. - Jason Spezza had two goals and an assist, and Alex Auld made 25 saves in Ottawa's 5-2 victory over the Buffalo Sabres on Monday night that snapped the Senators' four-game losing streak.
The Sabres (6-1-2) came in as the only Eastern Conference team without a regulation loss.
Dany Heatley had a goal and an assist, and Christoph Schubert and Shean Donovan also scored for the Senators (3-5-1), while Daniel Alfredsson added two assists.
Auld, playing in his third straight game in relief of injured starter Martin Gerber, improved to 5-0-2 lifetime against the Sabres. Ottawa won for the eighth time in the last 13 games against the Sabres in Buffalo.
Clarke MacArthur and Derek Roy scored, and Patrick Lalime finished with 23 saves for the Sabres, who have lost two straight, including a 2-1 shootout loss to Colorado on Saturday.
Buffalo, the top defensive team in the league after allowing just 1.6 goals per game coming in, was without defensemen Craig Rivet (knee) and Henrik Tallinder (lower leg laceration).
After Schubert scored his first of the season late in the first period while on the power play, Ottawa broke the game open with a three-goal second period.
Heatley made it 2-0 just 19 seconds into the second on the power play, wristing a shot from the slot past Lalime.
Spezza scored 4:29 later, lifting the puck over a sprawled Lalime on a partial breakaway, then increased Ottawa's lead to 4-0 late in the second by banging home a bouncing puck in the crease.
Donovan made it 5-0 nearly six minutes into the third after re-directing Jesse Winchester's pass in tight before MacArthur spoiled Auld's shutout bid with a power-play goal with Ottawa down two men with 5:23 remaining in regulation.
Roy capped the scoring on the power play with 32 seconds to go.
Buffalo converted just two of its 10 power-play opportunities.
