Cory Conacher scored at 2:48 of overtime, Jason Spezza completed a natural hat trick to erase a two-goal deficit and the Ottawa Senators ended a four-game losing streak with a 4-3 win over the Phoenix Coyotes on Tuesday night.

Phoenix took a 2-0 lead on quick goals by Rob Klinkhammer and Radim Vrbata in the second period, but the Senators rallied behind Spezza's fifth hat trick.

Mike Ribeiro tied it with just over three minutes left with his first goal of the season, redirecting a shot by Oliver Ekman-Larsson on a power play to send the game to overtime.

Conacher, who took a stick to the face in the second period, ended the game and Ottawa's opening six-game road trip by setting up in front and one-timing Marc Methot's pass from the left circle past a diving Mike Smith.
