Key play: Brad Richardson tapped a centering pass from Jordan Martinook into the net for the tie-breaking goal in the third period to lead the Arizona Coyotes to a 3-2 victory Tuesday over the Kings at Staples Center. Kings defenseman Brayden McNabb lost his stick on the play, allowing Richardson to camp out in front of Jonathan Quick’s net and to redirect the puck into the net at 11:47.

Pivotal performer: Kings winger Tyler Toffoli scored his team-leading 10th goal of the season, a power-play strike early in the second period. After only 15 games, Toffoli is nearly halfway to his career high of 23 goals, set last season in 76 games. Toffoli is tied for the league lead in goals.

Quote, unquote: “We were really sloppy in our own zone,” Kings captain Dustin Brown said. “Our coverage, and normally we’re very good at it, but the wingers need to be better.”

Hall of Fame honor: The Kings honored broadcaster Nick Nickson before the game, one day after he was enshrined in the Hockey Hall of Fame in Toronto. Nickson has worked for the Kings since 1981, a 35-season run that included calling Stanley Cup titles in 2012 and ’14.

Milestone moment: Kings defenseman Drew Doughty earned his career 210th assist on Dustin Brown’s first-period goal, moving past Lubomir Visnovsky for fourth place on the franchise’s all-time list. Steve Duchesne is third with 216 assists.

Lineup changes: Kings coach Darryl Sutter scratched defenseman Christian Ehrhoff for the second consecutive game. Ehrhoff has a minus-7 defensive rating to go with four assists in 13 games. Derek Forbort played in his place, as he did in Saturday’s victory over the Florida Panthers.
