ST LOUIS (Reuters) - The St Louis Blues snapped a five-game losing streak with a 5-2 win over the struggling Ottawa Senators Friday.

It was a third consecutive defeat for the Senators, who are on a poor run after winning four straight earlier in the month.

Ottawa took the lead in the opening period through Mike Fisher but Brad Boyes, Carlo Colaiacovo and Eric Brewer all scored in a 90-second spell in the second period for the Blues, who were dominant throughout.

Fisher raced in behind the Blues defense and took a perfect pass from Senators captain Daniel Alfredsson and lifted a backhand over Ty Conklin, making a rare start in net for the Blues.

Senators coach Cory Clouston called a timeout following the three goal outburst and delivered an animated speech to his team, who slowed the Blues offense thereafter but were unable to turn the game around.

"We had a real good first period, did a lot of good things," said Clouston.

"We turned the puck over a couple of times in the second period, and took four straight penalties that just killed all our momentum."

Andy McDonald and Patrik Berglund stretched the Blues lead in the third period before Jesse Winchester responded late on for Ottawa.

Conklin improved to 2-1-1 on the season and won his first game at home, providing some rest to Blues regular starter Jaroslav Halak who had allowed 19 goals in his last four starts while going 0-3-1.
