Kari Lehtonen made 27 saves in Dallas' first shutout since December, and the Stars beat the New York Islanders 3-0 on Saturday night to maintain their hold on sole possession of first place in the Western Conference.

Lehtonen earned his second shutout of the season and the 34th of his career. Cody Eakin, Patrick Eaves and Ales Hemsky scored for a depleted Dallas offense.

Tyler Seguin, the Stars' 33-goal scorer, is expected to miss the rest of the regular season after having surgery on Friday to repair a partially torn right Achilles tendon. Eakin stepped up with his 15th goal in the second period and Eaves with his eighth on a third-period breakaway. Hemsky scored his 12th into an empty net with 2:54 remaining.

Dallas has 95 points — four ahead of both Los Angeles and St. Louis, who each played later Saturday — with nine games left.
