KANATA, Ontario (AP) _ Jeff Shantz's second goal of the game, at 3:07 of overtime, lifted the Calgary Flames to a 4-3 win over the Ottawa Senators on Thursday night.

Shantz, who also had tied the game 2-2 in the second period, poked a loose puck past goaltender Ron Tugnutt from a scramble in front of the net to give Calgary just its second win in its last seven games.

Valeri Bure had a goal and three assists and Phil Housley added a goal and two assists for the Flames.

Andre Roy, Magnus Arvedson and Radek Bonk scored for the Senators, who lost at home for the first time in six games.

Ottawa took a 2-0 lead in the first period on goals by Roy and Arvedson.

But the Flames took advantage of Ottawa penalties with power-play goals by Housley and Shantz in a 36-second span early in the second to tie the game.

Bonk gave the Senators the lead with a breakaway goal at 15:33 of the second after taking a pass from Shawn McEachern and beating Grant Fuhr over the shoulder.

With just over eight minutes left in regulation, Bure picked up his own rebound on a partial breakaway and while falling down, slid the puck past Tugnutt for his ninth goal of the season to tie the game 3-3.

Calgary outshot Ottawa 37-28.
