Key play: Anze Kopitar scored on a deflection to give the Kings a two-goal lead in the third period en route to a 3-2 Freeway Series victory over the Ducks on Sunday at the Honda Center. Kopitar tipped Brayden McNabb’s perimeter shot into the net at 17:40 of the final period.

Pivotal performer: Andrew Cogliano scored what appeared to be the tying goal when a centering pass from Ryan Kesler deflected off his right skate and into the net. But a referee’s call on the ice washed out the goal and was confirmed by a video replay.

Quote, unquote: “I thought we took care of the puck a lot better tonight than we did last night,” Kopitar said, referring to a 5-3 loss Saturday to the Ottawa Senators in which the Kings failed to hold a 3-1 third-period lead. “We knew they were going to come hard. With the skill set they have, they made some plays. If we weren’t up to the task back there … we got away with a ‘W’ tonight.”

Dropping the gloves: Patrick Maroon of the Ducks earned a decision against the Kings’ Brayden McNabb in a first-period bout. The Ducks’ Chris Stewart wrestled with the Kings’ Luke Schenn after Schenn objected to Stewart’s hard hit on Alec Martinez moments earlier.

Injury updates: Ducks goaltender Frederik Andersen didn’t dress because of an upper-body injury. Anton Khudobin was recalled from San Diego to serve as John Gibson’s backup. Defenseman Clayton Stoner was played on injured reserve because of a hip flexor injury.

Roster move: Left wing David Perron made his Ducks debut after a late-night trade Friday from the Pittsburgh Penguins and scored a third-period goal. Perron skated on a line with center Ryan Kesler and right wing Jakob Silfverberg, which was Carl Hagelin’s spot before he was dealt to the Penguins.

Lineup shuffle: Kings coach Darryl Sutter scratched defenseman Christian Ehrhoff and forward Nick Shore. It was Shore’s double-minor for high sticking that led to the go-ahead goal Saturday in the Kings’ 5-3 loss to the Senators at Staples Center.
