For the second straight game, the New York Rangers gave up a power-play goal in the third period, this time to the St. Louis Blues in a 2-1 defeat.

Despite Rick Nash's sixth goal in four games, his third period penalty allowed for Kevin Shattenkirk to score the tie-breaking and winning goal.

Alexander Steen scored the Blues first goal and David Backes assisted on both of St. Louis' tallies.  Jaraslav Halak made 34 saves against Henrik Lunqvists 23, who was returning from the flu.

"For the first time in a long time I thought our power play let us down. It didn't make plays," forward Brad Richards said. "Just not enough hounding the puck. We played a real good hockey team, and they score on the power play, we don't."

The Rangers have now lost two in a row and look to right the ship on Sunday when they face off against the rival New Jersey Devils.
