DALLAS -- The Mavericks have signed first-round pick Dennis Smith Jr. to his rookie contract.
The deal announced Wednesday came as Smith prepared to join Dallas' summer team in Las Vegas.
The Mavericks drafted the North Carolina State freshman at No. 9 overall, their highest choice going into the draft since ending up with Dirk Nowitzki from the same spot in 1998. Dallas missed the playoffs for just the second time in 17 seasons.
Smith was the Atlantic Coast Conference freshman of the year before declaring for the draft. He reported to N.C. State early in January 2016 after tearing a knee ligament during his senior year in high school.
The 19-year-old Smith averaged 18.1 points, 4.6 rebounds and 6.2 assists in college.
Nick Young joining Warriors
OAKLAND, Calif. -- Veteran guard Nick Young is getting a new start with Golden State, agreeing to a $5.2 million, one-year contract with the champion Warriors.
Young's agent, Mark Bartelstein, confirmed the deal. Warriors general manager Bob Myers said the team would finalize a contract once the free agency moratorium period concludes Thursday.
The 32-year-old Young last month declined the player option in his contract with the Lakers.
In addition, forward Omri Casspi is joining the Warriors on a $2,106,470, one-year contract, a person with direct knowledge of the deal said.
Jefferson to keep playing
CLEVELAND -- After saying he would retire after the Cavaliers won the NBA title in 2016 and changing his mind, Richard Jefferson said Wednesday that he will be back with Cleveland next season -- his 17th as a pro.
The 37-year-old announced his plans on his "Road Trippin'" podcast.
Jefferson has one guaranteed season left on his contract worth $2.5 million. He averaged 5.7 points and 2.6 rebounds in 79 games for the Cavs, serving mostly as a backup for LeBron James.
No. 7 pick signs with Bulls
CHICAGO -- The Bulls have signed No. 7 overall draft pick Lauri Markkanen.

No. 8 gets enough
NEW YORK -- The Knicks have signed first-round draft pick Frank Ntilikina.
The 6-5 French guard and No. 8 overall selection is playing for New York's summer team in Orlando, Florida. The 18-year-old averaged 5.1 points, 2.1 rebounds, 1.4 assists and 18.5 minutes in 31 games last season for Strasbourg in the French Pro A league.
Pacers sign Sumner
INDIANAPOLIS -- The Indiana Pacers have signed second-round draft pick Edmond Sumner.
Sumner was selected by New Orleans with the 52nd pick and acquired in a draft-night deal. The Pacers picked up the 6-6, 176-pound point guard for cash considerations. At Xavier, Sumner averaged 11.4 points, 3.8 assists and 3.5 rebounds.
Wizards match Porter offer
NEW YORK -- Following his best season, Otto Porter Jr. has a big offer to join the Brooklyn Nets. It appears he'll be staying in Washington.
Porter has agreed to sign an offer sheet with the Nets, a person with knowledge of the details said. The Wizards plan to match the offer and keep Porter, according to the person.
The Vertical first reported that Porter had agreed to sign a four-year, $106 million offer sheet with the Nets. The Wizards would have two days to match the offer since Porter is a restricted free agent.
Source: Waiters, Heat agree
MIAMI -- Dion Waiters and the Heat have agreed on a four-year deal, according to a person with knowledge of the negotiations. The deal is worth a maximum of $52 million, provided all incentives are met.
Waiters averaged 15.8 points in 46 games last season for the Heat. The Heat were 27-19 when Waiters played, 14-22 when he did not. He filled the role vacated by Dwyane Wade.
OKC keeping Roberson
A person with knowledge of the situation says the Oklahoma City Thunder have agreed to terms with Andre Roberson on a three-year, $30 million contract.
The deal keeps Roberson in Oklahoma City, where he has emerged as a top-flight perimeter defender in four seasons.
Roberson averaged 6.6 points and 5.1 rebounds last season. But his real value is on the defensive end, where he often guards the opposing team's best scorer.
