ST. LOUIS — Jay McClement recorded his first career hat trick and T.J. Oshie and Brad Boyes scored in the shootout to lead the St. Louis Blues to a 4-3 victory over the Atlanta Thrashers on Saturday night.

Jaroslav Halak stopped both shots in the shootout to help the Blues to their fourth straight victory. The Thrashers lost for the first time in three games.

St. Louis, which improved to 5-0 at home, rallied from a late 3-1 deficit with two goals by McClement in a span of 1:46 in the third period. He deflected in a shot from the point by Alex Pietrangelo to tie the game 3-3 with 4:25 left.

Atlanta converted two power-play goals in the game's first 13:59 to take a 2-1 lead. Peverley popped in a rebound of a shot by Antropov for his first goal of the season.

The goal ended Halak's shutout string at 160:08. He had recorded consecutive shutouts and stopped 71 successive shots before Peverley's goal.
