Ottawa's fourth win in five games lifted the Senators past idle Toronto for the Northeast Division lead and pulled them even with Philadelphia atop the Eastern Conference with 66 points.
``It's healthy. We're pushing each other,'' Alfredsson said. ``We've got a great rivalry, a great race in our own division.''
Josh Langfeld added a goal and Brian Smolinski had a pair of assists for the Senators, who raised their road record to 12-6-3-1.
Shane Doan scored his 19th goal for the Coyotes, who lost their second straight and fell to 2-5-1-1 since moving into new Glendale Arena on Dec. 27.
Doan pulled the Coyotes to 2-1 on a power play 26 seconds into the third period, beating goaltender Martin Prusek between the pads from the high slot.
But Spezza tipped Smolinski's pass under goalie Brian Boucher at the top of the crease two minutes later to put Ottawa back in front by two goals.
``They scored on the power play, but we didn't panic,'' Marian Hossa said. ``We played the same game, and that's what you have to do.''
Phoenix coach Bobby Francis pulled Boucher for an extra attacker with 2:38 left, but the Coyotes managed just one shot before Alfredsson scored into the empty net with 58.2 seconds remaining.
``They responded the way you are supposed to after a team scores,'' Doan said. ``We needed to respond after that and we didn't.''
The Senators opened a 1-0 lead at 12:00 of the first period. Spezza fired wide from the right circle, gathered his own rebound off the end boards and beat Boucher with a sharp wrist shot from the right side of the crease.
Ottawa made it 2-0 at 8:58 of the second when Alfredsson's wrist shot from just inside the blue line glanced off Langfeld's arm and into the net.
``They suffocate you,'' Boucher said. ``It's extremely boring to watch and extremely boring to play. They make you do things you don't normally do. You lose your patience.''
