Kopitar has 919 points (325 goals, 594 assists) in 1,038 NHL games, passing Wayne Gretzky (918) for fourth place in Kings history.
"I'm sure he did that in about 400 games, so it took me a lot longer," Kopitar said. "But any time you are mentioned in the same sentence as Wayne Gretzky, it is a pretty big deal. I can brag about this one for a little while because I'm not going to break any of his other records."

Alex Iafallo had two assists for Los Angeles (14-18-3), which extended its point streak to four games (3-0-1).
"We got off to a good start, we checked and we had good structure for two periods," Kings coach Todd McLellan said. "We got away from that a little bit in the third period, but that's a good lesson to learn. We haven't played much with three or four-goal leads and we're learning how to handle it."
Jack Campbell, who is from Port Huron, Michigan, made 22 saves and Matt Roy, who is from Detroit, had an assist.
"This was really special because both [Roy] and I were playing for the first time at home," Campbell said. "I have so many memories of watching hockey at the Joe (Louis Arena), whether it was college or the Wings. It was pretty cool just to be out there and to get a win was even better."
