Cam Fowler's shot was stopped by Corey Crawford, but Getlaf poked the rebound under the sliding goaltender. Getlaf's sixth goal of the season came with Andrew Shaw in the penalty box serving a two-minute minor for too many men on the ice.
Jakob Silfverberg and David Perron scored in the third period for Anaheim, which dropped the first two games of the season series against Chicago in overtime. Frederik Anderson made five saves after John Gibson departed after two periods with an upper-body injury.
Defenseman Brent Seabrook had two goals for Chicago, which has dropped three in a row.
