Ryder's 3 points lead Stars to 3-1 win over Oilers
Mike Ribeiro also scored and had two assists for the Stars (42-30-5), who moved back atop the tight Pacific Division. Dallas has a one-point lead over Los Angeles and San Jose, and a two-point edge over Phoenix. Each team has five games remaining.
Ales Hemsky had the lone goal for the Oilers (31-37-9), who were 5-0-2 in their previous seven games.
Edmonton came close to going ahead early, just eight minutes in, on a short-handed 2-on-1 break, but Stars goalie Kari Lehtonen came across to make a kick pad save on Nick Schultz.
Dallas took a 1-0 lead 11:43 in when Ryder sped around Jeff Petry and chipped the puck over the stick of diving goalie Devan Dubnyk for his 34th goal.
The Stars took a two-goal lead 5:05 into the second period. Ribeiro took a return pass from Loui Eriksson on a 2-on-1 rush and banked the puck into the net off of Dubnyk.
Ryder had a breakaway chance, but Dubnyk made a stick save to keep it at 2-0 after 40 minutes.
Lehtonen kept the Oilers off the board early in the third, doing the splits to stop Jordan Eberle on a short-handed break.
The Stars made it 3-0 at 4:11 of the third when Ryder finished a tic-tac-toe passing play at the side of the net for his second goal of the game.
Edmonton broke Lehtonen's bid for his fifth shutout of the season at 8:21. Corey Potter's shot went wide but came off the boards to Hemsky at the other side of the net, and he scored into a wide-open goal.
