ST. LOUIS — Some of Erik Johnson's best hockey this season came right before the defenseman scored an overtime winner for the St. Louis Blues.

Facing Sidney Crosby and the talented Pittsburgh Penguins certainly brought out the best in Johnson, the No. 1 overall pick in 2006.

Johnson scored 50 seconds into overtime, Jaroslav Halak made 31 saves and the Blues beat the Pittsburgh Penguins 1-0 on Saturday night for their 10th straight home victory. In nine, the Blues have held the opposition to two goals or fewer.

Johnson scored his first goal of the season and it came after T.J. Oshie stripped the Penguins' Paul Martin of the puck in the corner. Oshie fed Johnson in the slot and the defenseman beat goalie Brent Johnson.
