Geekie took a pass from David Pastrnak and roofed a wrist shot over Darcy Kuemper’s blocker from the top of the right circle. It was his 16th goal of the season, which is tied with Nathan MacKinnon of the Colorado Avalanche for the NHL lead.
Jeremy Swayman made 31 saves, and Nikita Zadorov had two assists for the Bruins (13-10-0), who had lost two straight and three of their previous four.
Joel Armia scored a short-handed goal for the second straight game, and Kuemper made 24 saves for the Kings (10-6-6), who were coming off a 4-3 shootout loss at the San Jose Sharks on Thursday and are 0-1-2 in their past three games.
Geekie put the Bruins up 1-0 at 8:01 of the third period. Taking advantage of a line change, Geekie skated into a pass by Alex Steeves and scored with a long one-timer that beat Kuemper over his blocker.
Armia tied it 1-1 at 13:03. Trevor Moore’s shot on a 2-on-1 was stopped by Swayman, but Armia got to the rebound and knocked it into the open net with his backhand.
