Go figure — a rookie mistake cost the Senators Wednesday night.

It was obvious that David Rundblad was trying to do too much in his first game back after two in the pressbox.

When last we saw Rundblad, wasn't he a Swede? Against the Rangers, especially in the first period, he was more of a rushin' defenceman. His third dash up ice was stopped before it really started, but he was bailed out by Craig Anderson's good stop off a Marion Gaborik chance.

In the second, Rundblad coughed up the puck with a blind backhand pass from behind his own net. Quickly, the turnover turned into New York's second goal of the night. It was a lead the Blueshirts would never relinquish.

The Senators did have a great chance to tie the game in the third, but their leading scorer, Milan Michalek, inexplicably decided against his own chance from the slot to set up a defensive (rookie) defenceman, Jared Cowen, from a worse angle. Moments later, Gaborik enhanced his new reputation as a Senators killer with his second goal of the game.
