Dustin Jeffrey, Jarome Iginla and Tyler Kennedy all scored for the Pittsburgh Penguins (35-10), and the Pens won their seventh straight game and for the 22nd time in their last 24 tries, beating the Senators 3-1 in Ottawa on Monday night.
Still without the services of Sidney Crosby, Evgeni Malkin, James Neal and Paul Martin, the Penguins also played Monday without goaltender Marc-Andre Fleury, whose wife was expecting a baby, Kris Letang (food poisoning) and Beau Bennett (upper body injury).
Playing in his 700th NHL game, Tomas Vokoun (13-4) stopped 34 of 35 saves to become just the 28th NHL goaltender to reach 300 wins. Pittsburgh coach Dan Bylsma earned his 200th coaching victory.
Patrick Wiercioch scored the only goal for Ottawa (23-16-6).
On Tuesday night, the Penguins will return home for their makeup game with the Buffalo Sabres (19-21-6). Radio pregame time on 96.3 KQW will be 7:00 PM.
