BUFFALO - With right-handed defenseman Kevin Klein lost to an arm injury, the Rangers balanced the minutes between their six defensemen in Saturday night's 2-0 blanking of the Sabres.

Matt Hunwick and Keith Yandle, two of the four lefties, started the game together, but coach Alain Vigneault juggled a bit.

Hunwick, 29, who has played 40 games, played the least of the blueliners (15:29) but had four shot attempts. Yandle played 18:34 and Marc Staal 18:30.

The first pair, Ryan McDonagh and righty Dan Girardi, led in ice time with 24:02 and 24:18, respectively. Dan Boyle, the other righty, played 19:19.

"I felt pretty good, kept up with the pace," said Hunwick, who hadn't played since Feb. 24 and was a healthy scratch for seven games.

The Rangers have salary-cap room for a seventh defenseman, but Vigneault has said he'll go with six for the short term. After Sunday's home game, there is only one game -- against Chicago -- in the next five days.
