Ribeiro lifts Stars to 2-1 SO win over Coyotes
Loui Eriksson's first goal of the season tied the game with 28 seconds remaining in regulation and he scored on Dallas' first shootout attempt.
The shootout remained 1-0 until the Coyotes' last of three shots, when Shane Doan's shot deflected off Stars goalie Kari Lehtonen and into the top of the net. Ribeiro followed with a shot under Smith's right arm.
In the third period, Eriksson had deflected Sheldon Souray's drive from the left point over Smith's left shoulder to tie the score.
The game was scoreless until 5:55 of the third period, when Radim Vrbata scored 9 seconds into the Coyotes' sixth power play of the game.
The Stars had stopped their first nine power plays in their two home games, and 15 of 16 this season, before Vrbata knocked in a rebound of Martin Hanzal's shot.
Dallas had been called for its second bench minor penalty of the game for having too many men on the ice.
The Coyotes won the ensuing faceoff from the left of Lehtonen. Doan moved the puck across the ice, Hanzal took his shot from just in front of Lehtonen and to his right. The rebound slid in front of the net, where Vrbata swatted it in from just outside the crease before the goalie could slide back across to his left.
Phoenix outshot Dallas 40-25 during regulation and overtime. The Coyotes were 1 for 8 on their power plays, while killing all seven Stars opportunities.
There were five power plays in the first period. The Coyotes had three of the extra-man opportunities and outshot Dallas 11-7.
The Stars showed more life early in the second period, but Smith gloved Souray's drive, stopped Steve Ott's shot and pounced on the rebound of a Jamie Benn shot set up by Ott.
The Stars survived another power play after captain Brenden Morrow drew a cross-checking minor along with 5 minutes for fighting with Coyotes defenseman Rostislav Klesla at 9:47.
But Phoenix regrouped and outshot the Stars 14-10 in the period. The Coyotes' best chance came with 2 minutes remaining, when Lehtonen made a glove save on a shot by Raffi Torres.
Eriksson's goal made up for missing Dallas' best scoring opportunity of the game's first 59 minutes, on Phoenix's fifth power play. Less than 5 minutes into the third period, the Stars gained control of the puck, and Eriksson walked in alone on Smith. The goalie stopped the bid for a short-handed goal 3 seconds before the penalty expired.
