The defending Stanley Cup champions looked the part while evening their series against the St. Louis Blues.

The Los Angeles Kings dominated the second half of Game 4, powering past a pair of deficits behind forechecking that put the Blues on their heels, and have all the momentum in a series that's tied at 2.

The Kings' plan is simple for Game 5 Wednesday night in St. Louis: Keep the pedal down and play physical but smart.

So far, the home team has won all four games, and it's the only playoff series with every game decided by a single goal.
