The Golden State Warriors acquired Marcus Williams from the New Jersey Nets on Tuesday, filling their need for a backup point guard.

The Warriors, who lost Baron Davis to the Los Angeles Clippers in free agency, traded a conditional first-round draft pick to the Nets for Williams, a first-round pick in 2006.

Williams averaged 5.9 points and 2.6 assists in 53 games with the Nets last season after missing the first 23 games with a broken right foot. He made the NBA's all-rookie second team in 2007 after a three-year career at Connecticut.

“Marcus is a good young ballplayer with outstanding skills,” Nets president Rod Thorn said. “This transaction allows us to acquire another future asset, and we wish Marcus the best in his basketball future.”

Monta Ellis is expected to become Golden State's starting point guard in the upcoming season, but the only other point guard on the Warriors' roster after Davis' departure was unproven youngster C.J. Watson.

CHARLOTTE: An MRI exam confirmed the Charlotte Bobcats' initial diagnosis that rookie center Alexis Ajinca has a sprained left knee, and not a more serious knee injury requiring surgery. Ajinca suffered the injury last week, during a summer-league game in Las Vegas.

PHOENIX: Well-traveled sharpshooter Matt Barnes signed a one-year contract with the Phoenix Suns on Tuesday.

“He has a chance to have a big impact on our team,” Suns general manager Steve Kerr said. “His athleticism and versatility at both ends of the court will be important for us, along with his playoff experience.”

SAN ANTONIO: The San Antonio Spurs re-signed Kurt Thomas on Tuesday, getting the veteran forward under contract after trading for him in February.

Terms of the deal weren't disclosed but Spurs general manager R.C. Buford said Thomas will be with the team at least two seasons.

The 6-foot-9 Thomas, a 14-year veteran, was unavailable for comment.
