PITTSBURGH (AP) -Steven Stamkos scored his 46th goal to edge within one of NHL leader Sidney Crosby and the Tampa Bay Lightning prevented Pittsburgh from gaining ground in the Eastern Conference race, beating the Penguins 2-0 on Wednesday night.
Crosby and the Penguins couldn't find the net on a 5-minute power play in the first period resulting from just-recalled defenseman Matt Lashoff's boarding penalty and went on to lose their fourth in six games after winning their previous two.
Pittsburgh missed an opportunity to take a three-point lead in the Atlantic Division over idle New Jersey. The Lightning had lost 14 of their previous 18 overall and were coming off a 3-2 loss in Columbus on Tuesday night.
Lightning goalie Mike Smith made 27 saves for his second shutout of the season.

Rookie Logan Couture had a power-play goal for San Jose, the Western Conference leader with 104 points - three better than second-place Chicago. Sharks points leader Joe Thornton missed his second straight game because of a lower-body injury.
BUFFALO, N.Y. (AP) - Jason Pominville scored his team-leading 24th goal to help Buffalo inch closer to clinching the Northeast Division title.
