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 got off to a fast start with a 9-2 edge in shots before Goligoski notched the game's only goal and 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.
Goligoski signed a four-year contract extension worth $18.4 million on Monday.
Hiller stopped 15 shots for the Ducks, who had been 8-0-1 in their previous nine games.
Once 20 points out of the eighth spot in the Western Conference, the Ducks have returned to the fringe of the playoff race. But they still have some catching up to do, starting the night 11 points out of the final postseason berth.
Dallas remains without All-Star center Jamie Benn (appendectomy) and captain Brenden Morrow (neck). Benn is expected to play in Sunday's NHL All-Star game then return to the Stars lineup.
Ribeiro was back after missing seven consecutive games because of a knee injury.
Anaheim held a 19-7 shots-on-goal advantage after two periods, but the Ducks couldn't get the puck past Lehtonen, who earned his first shutout of the season. Lehtonen denied Ducks All-Star Corey Perry from close range seconds before the final buzzer.
Dallas was able to control Anaheim's hottest scorer, right winger Bobby Ryan, who had four goals in his previous five games.
Both teams played their final game before the All-Star break.
