Jake Allen made 28 saves for his fourth shutout this season, and Vladimir Tarasenko broke a scoreless game with a goal in the third period in the St. Louis Blues' 3-0 win over the Dallas Stars on Sunday.

The Blues added a power-play goal by Alexander Steen and an empty-netter by T.J. Oshie in the final 3:15. It was Allen's fifth career shutout.

Tarasenko skated down the slot and fired a shot past Kari Lehtonen into the lower right corner 3:33 into the third. It was Tarasenko's second game-winning goal in Dallas this season.

Steen and Oshie each had a goal and an assist, and teammate Alex Pietrangelo had two assists. St. Louis killed all six Stars power plays. The Blues' penalty killers have been successful in 29 of 30 chances over the last nine games.

Neither team scored in the first period, even though Dallas had two power plays and St. Louis had one. The Blues didn't put a shot on goal during their power play.

Dallas missed another power-play opportunity, without a shot, 3 ½ minutes into the second period. The Stars' Jyrki Jokipakka had a scoring chance 5 minutes after that when he shot high, then sent the rebound off the glass into Allen.

Tyler Seguin had the only shot on goal near the end of Dallas' next power play, but Allen stopped the puck on his short side and fell on the rebound.

Lehtonen gloved a drive from the right point by Alex Pietrangelo at 16:26 of the second. Each team finished the period with seven shots.

Just 1:40 into the third period, Tarasenko corralled a loose puck and shot, but Lehtonen made the save. A short time later, Dallas defenseman Jason Demers cleared a loose puck that was sitting in the crease.

The Stars had a chance to tie the game 7 minutes into the period during their fifth unsuccessful power play, but St. Louis' Paul Stastny cleared a loose puck away from the crease.
