The Blues matched that at 4:39 of the second period. Polak's long slap shot

deflected off the body of forward Chris Porter in

the slot, changed directions, and got past Quick at

4:39.

The Kings got a break on their go-ahead goal. Penner's long shot deflected off Polak and sailed upward, eluding Elliott after he had sunk to his knees and sailing into the net. The goal was reviewed at the NHL's Toronto office and deemed to be good.

“They played a great series,” Penner said. “They got unlucky a few times. We got lucky.”

And they got to go on to the second round and give themselves a chance to write a sequel to last season's triumph.

“We still have some work to do,” Richards said. “We played well enough to win the series. We can still get better and that was our goal from day one this year — improve right through to the last day.”

With that last day, they hope, coming sometime in late June.
