The second-team All-Metro League pick also had an offer from Washington.
Cleveland High senior small forward CJ Elleby announced his commitment to Washington State via Twitter on Saturday.
Elleby, who is 6 foot 6, was a second-team All-Metro League player last season. He said earlier this summer he also had offers from Washington and Seattle U among others.
CJ is the son of Bill Elleby, who played at Garfield and at Cal. He runs the the Seattle Basketball Services scouting service.
