RALEIGH, N.C. -- Alex Ovechkin and the Washington Capitals are looking to defend the Stanley Cup. And they're not going down without a fight.

Ovechkin fought -- and knocked out -- Carolina Hurricanes forward Andrei Svechnikov in the first period of Game 3 of the teams' first-round series on Monday night, a 5-0 win for Carolina.

Svechnikov, 19, is the youngest player in the NHL playoffs this season. A native of Barnaul, Russia, Svechnikov has said that he grew up idolizing Ovechkin, his countryman who is 14 years his elder. Svechnikov appeared to provoke Ovechkin, and the two exchanged words before dropping the gloves. Svechnikov got a few jabs in before Ovechkin dropped Svechnikov with three hard rights.

Svechnikov's head hit the ice on the way down. Svechnikov stayed down on the ice for several minutes before he was helped off by Carolina trainers. He was later ruled out by the Hurricanes to return. Both players received five minutes for fighting.

According to HockeyFights.com, Ovechkin has fought only four times in his NHL career -- and not since 2010.

Svechnikov scored two goals and tallied one assist in the Hurricanes' first two playoff games. Ovechkin won his record eighth Rocket Richard Trophy this season as the league's top goal scorer. He has one goal and two assists in the Capitals' first two games these playoffs.

The Hurricanes are hosting their first playoff game in a decade. Washington holds a 2-1 series lead after the loss.

SACRAMENTO, Calif. -- The Sacramento Kings hired Luke Walton as their coach on Monday, just days after the Los Angeles Lakers parted ways with him following three losing seasons.

Neither the Kings nor Walton waited long following changes that came just after the regular season. Sacramento fired coach Dave Joerger on Thursday following a 39-43 finish that was the best record for the franchise in 13 years. Walton was dismissed in Los Angeles a day later after failing to get the Lakers into the postseason in the first year with LeBron James.

Kings general manager Vlade Divac met with Walton on Saturday and the two sides quickly came to the agreement that was formally announced Monday.

Walton, 39, was 98-148 with Los Angeles in his first full-time head-coaching job, missing the playoffs all three seasons. He was 37-45 this season.

Walton also has experience as an assistant for Golden State, helping the Warriors win the 2015 title and then leading the team to a 39-4 record, including 24 straight wins to open the 2015-16 season, as interim coach while Steve Kerr was sidelined following complications from a pair of back surgeries.

That performance helped Walton get the job with the Lakers, but he was unable to duplicate that success with a roster with far less talent during his first two seasons and then again this year with James on board.

Walton takes over an up-and-coming team in Sacramento that features several talented young players acquired by Divac: guards De'Aaron Fox and Buddy Hield, forward Marvin Bagley III and center Willie Cauley-Stein. The Kings finished nine games out of a playoff spot after being tied for the Western Conference's eighth seed heading into the final game before the All-Star break.

Sacramento had its most wins since going 44-38 in 2005-06, during coach Rick Adelman's final season. That ended a run of eight straight playoff berths, and Sacramento hasn't been back to the postseason since for the NBA's longest active drought.

Joerger was the ninth coach since Adelman was fired in 2006 and none was able to post a winning record or earn a playoff berth. In fact, since they moved to Sacramento before the 1985-86 season, the only winning seasons for the Kings came in Adelman's eight years at the helm, highlighted by a trip to the Western Conference finals in 2002.

Divac is now counting on Walton being the one who can get the team back to the level it reached under Adelman, when the Kings were a contender for several years and played an entertaining brand of basketball.

Duke freshman Zion Williamson, the consensus player of the year, made it official Monday, declaring his eligibility for the NBA draft.

Williamson, whom ESPN ranks as the No. 1 prospect in the June draft, made his announcement on Instagram, saying it had been the "best year" of his life and thanking those who helped make his dream a reality.

The 6-foot-7, 285-pound Williamson captivated all of college basketball with his freakish, once-in-a-generation athleticism, his energy at both ends of the floor and his omnipresent charisma.

Williamson, 18, averaged 22.6 points and 8.9 rebounds per game while ranking second nationally by shooting 68 percent. He won the Wooden Award and the Naismith Award and was named player of the year by the Associated Press and the U.S. Basketball Writers Association.

He became the face of college basketball this season, routinely coming up with at least one highlight-reel play or show-stopping dunk per game.

On May 14, the NBA will hold its lottery to determine which team has the right to draft Williamson. New York, Phoenix and Cleveland hold the best odds, followed by Chicago and Atlanta.

Williamson's decision to turn pro came as no surprise. He spent the season greeting NBA chatter with a playful wink and a knowing nod.

He said it would be "dope" to play on a hypothetical New York Knicks team with Kyrie Irving and Kevin Durant. Upon learning that LeBron James and Stephen Curry were talking about him during All-Star Weekend, he responded by saying that he is "hoping to be there competing against them next year."

During his lone college season, Williamson helped the Blue Devils earn the No. 1 ranking in the final AP Top 25 and the top overall seed in the NCAA tournament. Duke was knocked out by Michigan State in the East Regional final.

Now that Williamson is headed to the NBA, one key subplot to follow is which sneaker company will land his endorsement.

In one of the biggest moments of the season, Williamson blew out his left Nike shoe -- the PG 2.5, the signature shoe of Oklahoma City star Paul George -- and sprained his right knee in the opening minute of what became a lopsided home loss to rival North Carolina.

The impact was immediate: Nike's stock price took a hit the next day, and the shoe company sent a team of representatives to Duke's campus to investigate. When Williamson returned roughly three weeks later for the ACC tournament, he wore a pair of modified size-15 Nikes from Irving's signature line.

He opened in February at -2000 to be drafted No. 1 overall at DraftKings. After his decision to declare, he's now up to -5000.

Williamson joins RJ Barrett and Cam Reddish as classmates headed to the pros after one season. Point guard Tre Jones said he will return to school for his sophomore year.

OAKLAND, Calif. -- Clippers head Doc Rivers lost $2,000 dollars on the San Francisco streets Monday morning only to have a stranger give it back to him.

Rivers ended his pregame news conference prior to Game 2 of the Clippers' Western Conference quarterfinal against the Golden State Warriors by telling the story of a random act of kindness that left the assembled media in awe.

"Last thing," Rivers said after the questions finished. "Shout out to the San Francisco person who at the corner today, I was walking down the street -- this is a true story -- I reached in my pocket to grab my phone, unbeknownst to me I dropped about two grand on the street, kept walking, didn't know it. A guy tapped me on the back and said, 'That's your money.'"

Rivers, who grew up in Chicago and spent time playing for the New York Knicks during his 14-year playing career, couldn't believe his luck.

"I don't know a lot of places that that would happen," Rivers said. "But it happened today, so whoever that was, you could have had free tickets if you hadn't have ran away."

PHILADELPHIA -- It might have taken a game and a half, but the Philadelphia 76ers finally arrived at their first-round series against the Brooklyn Nets with a historic third quarter in Monday night's 145-123 win.

Leading by just one at the half after dropping Saturday's Game 1 at home to fall behind in the series, the Sixers outscored the Nets 51-23 in the third quarter with a dazzling display of precision on both ends.

Joel Embiid, a game-time decision because of discomfort in his left knee, got things started, going on a personal 8-0 run. Embiid's spark extended to the entire team as Philadelphia pushed the run to 21-2 in the first four minutes of the quarter. Philadelphia shot 6-for-8 (corralling the offensive rebound on both of those misses) while Brooklyn went just 1-for-8 (0-for-3 on 3-pointers) with three turnovers in that span.

The 51 points tied the Los Angeles Lakers for most points in a quarter in a playoff game by a team. The Lakers had 51 in the fourth quarter against the Detroit Pistons on March 31, 1962.

Embiid left the game in the fourth quarter after rolling his ankle when Nets forward Rondae Hollis-Jefferson stepped on his foot going up for a basket near the rim. Embiid went to the bench and grabbed the ankle, wincing. He stayed on the bench and did not appear to receive treatment for it.

Entering Game 2, Sixers coach Brett Brown acknowledged how important it would be to climb back into the series.

"For sure, anxiety and urgency gets expedited when you lose at home in Game 1," Brown said. "And because we've all kind of been doing this awhile, you learn. And you try to avoid this in a regular season, where the highs and lows aren't as dramatic. In the playoffs, it's hard to avoid that. Like, even as sane as I try to be and preach about psychological stability and a balance, you're mindful.

"Like, tonight is a really big game. And so you can't deny that. And so be it. That's what you coach and you play for, and there's nothing like the NBA playoffs. ... So, we feel it. We feel it, and I think that's a good thing. I really do. I look forward to watching us respond to our loss at home from the other night."

Game 3 is Thursday in Brooklyn.

Clippers coach Doc Rivers ended his press conference by telling an unprompted story about how he was walking around San Francisco, reached into his pocket to grab his phone and accidentally dropped $2,000 on the ground. He didn't know he had dropped the money and started walked away, but then someone came up to him and told him, "That's your money." Said Rivers: "I don’t know a lot of places that that would happen, but it happened today. So whoever that was, you could’ve had free tickets if you hadn’t run away.”

The Philadelphia Phillies have placed reliever David Robertson on the 10-day injured list with soreness in his pitching elbow.

Robertson, 34, has a 5.40 ERA in seven appearances this season, his first with the Phillies. The right-hander threw two scoreless innings Sunday in Philadelphia's 14-inning victory over the Marlins.

The Phillies signed Robertson to a two-year, $23 million contract this past offseason.

Philadelphia recalled right-hander Drew Anderson from Triple-A Lehigh Valley on Monday in a corresponding roster move.

Arizona Diamondbacks closer Greg Holland threw a couple of tight inside pitches to the San Diego Padres' Francisco Mejia during Sunday's ninth inning, raising questions about whether it was in retaliation for Padres pitchers hitting two Diamondbacks with pitches on Saturday in Phoenix.

Arizona manager Torey Lovullo said all that mattered was that Holland got three outs to end the 8-4 victory.

But Padres manager Andy Green had some choice words for the umpiring crew.

"Umpires being literally clueless on the field right now. That's inexcusable at that point in time," Green said. "The first one, OK maybe slips. The second one, we know what is going on there. It is not lost on us at all. If it is lost on them (umpires), they are not paying attention to the baseball game."

BOSTON -- Brandon Hyde was ejected for the first time as Baltimore Orioles manager, tossed in the fifth inning Monday against the Boston Red Sox.

Hyde came out to challenge the "slide rule" after a force play scored a run. Once the call was upheld, he came out to argue with first-base umpire Mark Wegner and was ejected.

With runners on first and third with no outs, Steve Pearce hit a roller to third. Rio Ruiz made the throw to second, where Jonathan Villar made a late throw to first just as Rafael Devers was sliding into the bag and came up a bit.

Baltimore leads 4-1.

Hyde was ejected from a game last June when he was the Cubs' bench coach.

The Cleveland Indians activated two-time All-Star second baseman Jason Kipnis off the 10-day injured list ahead of Monday's game against the Seattle Mariners.

Kipnis hasn't played this season after suffering a low-grade right calf strain late in spring training. He played just 10 games in spring training because of hip, quad and calf injuries and appeared in six games at Triple-A during his recently completed rehab assignment.

In a separate move, the Indians designated infielder Brad Miller for assignment. Miller hit .250 in 13 games for the Indians.

Entering his ninth MLB season, Kipnis has played his entire career with the Indians. He was an All-Star in 2013 and 2015, but he batted a career-worst .230 in 147 games last season.

In more good news for Cleveland on the injury front, shortstop Francisco Lindor has been sent to Triple-A to begin a rehab assignment as the All-Star moves closer to rejoining the big league club after being slowed by a left ankle injury.

The switch-hitting Lindor was making steady progress from a right calf injury when he rolled his ankle while caught in a rundown during a minor league scrimmage in Arizona. Lindor batted .277 last season with 38 home runs, 92 RBIs and 25 steals.

Lindor was hopeful of playing Monday night with Columbus, but travel delays pushed his first game back to Tuesday. Cleveland manager Terry Francona didn't have a set number of games for Lindor to play before rejoining the Indians.

"It's going to depend on how he feels, and the last thing we want to do is slow him down,'' Francona said. "But we want to set him up for success. We want to make sure he's OK.''
