The Muir boys' basketball team, which went 24-2 and won the Pacific League title for the first time in over a decade, missed the CIF-Southern Section Division 4AA playoffs after forfeiting 20 games for using an ineligible player.
The school failed to prove a valid change of address for 6-foot-5 senior forward Andre Frazier, according to the Pasadena Star-News.
"We're shocked," Muir coach Gamal Smalley told the newspaper. "I know our administration worked really hard to make sure they could provide everything that CIF was asking for, and I thought they came close."
Frazier transferred last year from Fairfax, and also previously attended Burbank Bellarmine-Jefferson and L.A. University.
As a result, nine-time league champion Pasadena, which came in second place in the Pacific League and received a No. 2 seeding in Division 3AAA, repeats as titlist.
