A popular furry beast made a rare appearance Tuesday morning at City Hall. Slamson, the mascot for the Sacramento Kings, joined with local officials to promote Tyreke Evans as the choice for NBA Rookie of the Year. Mayor Kevin Johnson, Assemblyman Roger Niello and County Supervisor Jimmie Yee all turned out for the press conference to cheer for Evans. “Rally for RekeROY Night” will take place March 10 during the game between the Kings and the Toronto Raptors at Arco Arena.
