The Los Angeles Lakers are acquiring former lottery pick Rui Hachimura from the Washington Wizards in exchange for Kendrick Nunn and a package of second-round draft picks, a person familiar with the negotiations said Monday. The person, speaking to The Associated Press on condition of anonymity because the trade has not been finalized and approved by the NBA, said the teams are working under the expectation that the deal will be completed later Monday. Hachimura and the Wizards did not agree on a rookie extension before the season started, which prompted speculation that the Japanese power forward wouldn’t be in their long-term plans.
