OTTAWA -- Lucky Seven for the Pittsburgh Penguins put a dent in the Ottawa Senators' playoff hopes. Tomas Vokoun made 34 saves in collecting his 300th career win Monday as the Penguins defeated the Senators 3-1 for their seventh straight victory, dropping Ottawa into eighth place in the Eastern Conference. "They were better than we were from start to finish," Senators coach Paul MacLean said bluntly. "They were harder at the nets ... at both nets than we were and executed way better than we did." Dustin Jeffrey, with a goal and an assist, Jarome Iginla and Tyler Kennedy scored for Pittsburgh (35-10-0), which got two assists from Brenden Morrow.
