It has widely been reported that Westbrook will head to LA with a three-player exchange the other way, including pick 22 in the NBA Draft which was held on Thursday.
The Lakers will send trio Kyle Kuzma, Montrezl Harrell, Kentavious Caldwell-Pope to the Wizards.
“Thank you DC! You welcomed my family and I with open arms from day one,” Westbrook tweeted.
“Everyone from the front office, to the training staff, the coaches, my teammates, and the fans.
“I’m grateful y’all took a chance on me and supported me every step of the way.
“I’m blessed to have been a part of such a stand up organization.
“It didn’t take long to make a home in DC, and I will forever be grateful and appreciative of my experience with the organization. Thank you!”
The trade cannot be made official until August 6 when the NBA salary cap gets confirmed.
Westbrook averaged 22.2 points, 11.5 rebounds and 11.7 assists for the Wizards last season, breaking Oscar Robertson’s triple-double record.
