Jeff Carter also scored his 20th goal of the season for Los Angeles, which has lost just once in regulation in Dallas in its last 14 visits (11-1-2) and outshot the Stars 40-15.
Richardson's goal was particularly impressive, since the fourth-liner was playing his first game since Feb. 10 and third of the season overall after sitting out as a healthy scratch the other 32 contests. Jonathan Bernier needed to make just 15 saves for the Kings.
Jamie Benn and Ray Whitney scored for Dallas, which had won both previous meetings between the Pacific Division rivals this season by a combined score of 7-2.
I feel that responsibility, I've felt it for the last two years. We core guys get a lot of minutes, we get a lot of opportunity out there. Our teammates, the organization and fans look to us to be the guys to put the puck in the net and to create momentum out there.
