Dustin Brown had a goal and an assist, and Trevor Lewis and Justin Williams also scored for the Kings. Jarret Stoll assisted on Lewis' goal, giving him 100 with Los Angeles.
The win gives the Kings only their second sweep of a season series against St. Louis after first doing it in 2005-06. Los Angeles has beaten the Blues eight straight times, including a 4-0 sweep in last season's Western Conference semifinals.
Vladimir Tarasenko scored both goals and Jaroslav Halak made 36 saves for the Blues, who have lost four of their last five.
Richards capitalized when Halak gave up a rebound on a soft shot. The puck went to the right side of the net, but came back in front and Richards eventually jammed it in for his 10th goal.
Williams closed the door on an empty-netter with 1:16 remaining.
Tarasenko tied it for the second time when he shoved home a puck that had drifted through Quick at 6:44 of the third period to make it 2-2. The Blues rookie had also knotted the score at 1 when he put his own rebound past Quick at 10:55 of the second period.
Lewis made it 2-1 at 12:49 of the second when he corralled a bouncing pass from Stoll to the right of the Blues' goal and sneaked a backhander past Halak.
Notes: Blues G Brian Elliott, who is 3-6-1 with a 3.56 goals against average and has not played since March 5, agreed to go to Peoria of the AHL for conditioning. Elliott led the NHL in goals against average last season (1.56) and helped the team win the Jennings Trophy. ... Anze Kopitar had an assist, giving him 22 points in his last 19 games. ... Tarasenko's first goal snapped an 0-for-12 streak on the power play for St. Louis.
SEOUL, South Korea (AP) - North Korean leader Kim Jong Un has ordered his forces on standby to strike the U.S. mainland, South Korea, Guam and Hawaii.
State media say Kim "convened an urgent operation meeting" of senior generals just after midnight and signed a rocket preparation plan. The North is fuming after just yesterday, U.S. nuclear-capable B-2 bombers dropped dummy munitions in joint military drills with South Korea.
And tens of thousands of North Koreans turned out for a 90-minute mass rally today in support of Kim's call to arms.
The No. 4-seeded Orange won't have that element in their favor in the NCAA tournament's East Regional final.
That's because Syracuse will face a familiar foe Saturday with a Final Four berth at stake: Big East rival Marquette, the East's No. 3 seed.
"We're much better when we play teams that don't know us," Boeheim said. "Marquette knows us. They know how to play against us, so it will be very difficult."
Paced by Michael Carter-Williams' 24 points, Syracuse reached the round of eight with some dominant defense during a 61-50 victory over top-seeded Indiana in the regional semifinals Thursday night. The Orange forced 19 turnovers, blocked 10 shots, and limited the Hoosiers to 33 percent shooting while holding them to their lowest scoring output of the season.
"Our perimeter defense was tremendous," Boeheim said in an arena hallway afterward, his arms crossed across his purple tie, the way he stood for much of the lopsided game. "This is one of our best defensive teams ever. They play it well."
There's an understatement.
"In practice, it's hard to simulate how tall they really are," said Indiana's Jordan Hulls, a 6-foot senior who was at least 4 inches shorter than the players usually guarding him and went 0 for 6 on 3-point tries. "We had the right game plan. We prepared really well. But we had too many turnovers."
Three more, in fact, than shots made (16).
"Let's face facts. We haven't seen a zone like that," Indiana coach Tom Crean said. "They're very good. They're where they're at for a reason."
Next up is Marquette (26-8), which beat No. 2 seed Miami 71-61 in Thursday's first game in Washington.
Syracuse (29-9), heading to the Atlantic Coast Conference this summer, lost at Marquette 74-71 during the Big East regular season on Feb. 25.
That was part of a stretch in which Syracuse lost four of five games. Since then, though, the Orange are 6-1, with the only loss coming against Louisville in the conference tournament final. In that game, Syracuse fell apart in the second half, going from a 16-point lead to trailing by 18 in a 13-minute span.
The Orange built an 18-point lead in the first half against Indiana, and while that dwindled to six early in the second half, Boeheim's squad never let it get closer than that.
The last time these two schools faced off in the NCAA tournament, Indiana won the 1987 championship on a late shot - and it took winning the 2003 national title with Carmelo Anthony for Boeheim to get over it. That decade-old group was also Syracuse's last visit to the Final Four.
Less than a half-minute into Thursday's game, as Indiana star Victor Oladipo headed to the free-throw line, the arena's overhead scoreboard showed a replay of "The Shot," as it's come to be known - Keith Smart's baseline jumper in the final seconds that lifted Bob Knight's Hoosiers past Boeheim's Orange.
Boeheim entered Thursday with 50 wins in the tournament, fourth-most in history, and more than 900 victories overall, with so much of that success built on his unusual zone defense, 40 minutes of a puzzle for opponents to try and solve.
Indiana (29-7), like most teams outside the Big East, isn't used to seeing that sort of thing, and it showed right from the outset. Didn't matter that Indiana ranked third in the country this season in scoring, putting up 79.5 points per game - and never fewer than 56 - while making 48.6 percent of its shots.
"Not too many teams are used to our zone," said Brandon Triche, who scored 14 points Thursday and whose uncle, Howard, was on Boeheim's 1987 squad. "That's what we play. Other teams that play zone, they (also) play man, they switch up defenses. But our main (thing) is zone. ... We're very long, and we're very active, and when we're active like we were today, we're hard to score on."
Cody Zeller was held to 10 points on 3-of-11 shooting. Oladipo scored 16 for Indiana, none easily.
"Credit them," Oladipo said, his head bowed and voice hushed. "They did a great job with their zone. They're well-coached."
Boeheim looked on calmly, occasionally resting his chin on his right fist while seated. He seemed something like an interested observer rather than active participant in the proceedings.
Sure must have liked what he saw, though.
"They never really succeeded in getting the ball in the right places," Boeheim said about the Hoosiers. "And it's not that easy, but it can be done. But they didn't know how to do that."
JEFFERSON CITY, Mo. (AP) - Missouri House Speaker Tim Jones is increasing his push to get the attorney general to appeal a ruling against a new law creating a moral exemption from mandatory insurance coverage of birth control.
Jones filed a resolution Thursday in the House that, if passed by both chambers, would officially ask Attorney General Chris Koster to appeal the decision. Jones previously sent a letter to Koster requesting an appeal.
The Republican-led Legislature overrode a veto by Democratic Gov. Jay Nixon last year to enact a law requiring insurers to issue policies without contraception coverage if individuals or employers say it violates their "moral, ethical or religious beliefs."
A federal judge struck down the law earlier this month, ruling that it conflicted with a provision of President Barack Obama's health care law.
