In a battle of division leaders fighting it out for the top spot in the Western Conference, Selanne also scored his 39th goal of the season in his reunion with longtime Ducks linemate Paul Kariya. Selanne, who eclipsed Kariya's franchise records for goals and game-winners earlier this season, needs 20 points, 24 assists and three power-play goals to break Kariya's club records in those categories.
Penner extended his goal-scoring streak to four games, the longest by a rookie in Ducks history. Penner could have had two, but he hit the right post from close range with four minutes left in the first period.
Kimmo Timonen and J.P. Dumont scored first-period goals for the conference-leading Predators, who had a season-low 14 shots and none in OT. Kariya scored their only goal in the shootout.
The point Nashville got in the defeat, coupled with Detroit's overtime loss to Colorado, put the Predators three points ahead of the Red Wings in the Central Division and four ahead of the Pacific Division-leading Ducks.
Nashville played without Peter Forsberg, David Legwand and Steve Sullivan, all out with minor injuries. Jason Arnott missed his second straight game with flulike symptoms.
