Kari Lehtonen made 27 saves for his 18th career shutout, defenseman Alex Goligoski scored in the first period, and the Dallas Stars ended Anaheim's five-game winning streak with a 1-0 victory over the Ducks on Tuesday night.
The Stars had been 0-4-1 with six goals in their previous five games, damaging their playoff chances.
Anaheim had been off to a fast start, holding a 9-2 edge in shots when Goligoski notched the game's only goal with his sixth of the season.
Goligoski's shot glanced off Ducks defenseman Cam Fowler, with the puck flipping into the air and over Anaheim goaltender Jonas Hiller with 3:39 left in the first. Mike Ribeiro and Loui Eriksson were credited with assists.
Hiller stopped 15 shots for the Ducks, who had been 8-0-1 in their previous nine games.
