Captain RyanGetzlaf and Corey Perry led a strong offensive effort by the Pacific Division champions, who finished the regular season with the best winning percentage in franchise history.
Getzlaf first fed Ryan on a rush for the tying goal with 5:27 to play before setting up the 42-year-old Selanne for his 670th career goal with 4:23 left, ending the Finnish Flash's nine-game goal drought.
Getzlaf set up Bobby Ryan's tying goal and Selanne's tiebreaker 1:04 apart in the waning minutes, and the Ducks rallied for a 4-2 victory over Chicago in a meeting of the NHL's top two teams.
Anaheim finally broke through when Getzlaf brought the puck down the wing and fed it in front to Ryan, who banged it through Kyle Palmieri's screen for his ninth goal.
