"One of the keys was getting on them right away," Fiddler said.

Dallas rookie Richard Bachman stopped 34 shots in his seventh consecutive start in place of Kari Lehtonen, who is out with a groin injury but is expected back within a week.
Bachman was perfect in the first period while Nashville had 17 shots on goal, and good enough the rest of the way to improve his record to 5-2.
"He's had tough times in that we're playing him in just about every game," Stars coach Glen Gulutzan said. "I thought he made some key saves tonight. He left a couple of rebounds that we cleaned up, and that's not like him."
The Predators were coming off a 6-5 home win over Columbus on Thursday night, when they rallied from a three-goal deficit. This time, their comeback bid fell short.
"We're down 3-0 right away," coach Barry Trotz said. "You can't dig yourself a hole and come out of it every night. You're battling back, gaining momentum, the next shift is crucial. We did that twice (gave up a goal after narrowing the deficit to one) and that's unacceptable. We've got to firm up."
Second-period goals by Matt Halischuk and Martin Erat drew the Predators to 3-2, but Ribeiro got one back for Dallas later in the second to extend the advantage.
David Legwand's power-play goal at 4:38 of the third again pulled the Predators within a goal at 4-3, but Benn's goal 30 seconds later restored the Stars' two-goal cushion.
Halischuk got the Predators on the board at 8:56 of the second, powering a rebound past Bachman during a pileup in front of the net.
Erat struck from the right circle during a 5-on-3 at 11:45 of the second to make it a one-goal game, but Ribeiro extended Dallas' lead to 4-2 at 14:10 on a sharp-angle shot.
"We came back with big goals at the right time," Ribeiro said. "To get quick goals like that meant that we always had the lead."
