Quade says Zambrano cleans out locker and walks out on teammates after loss

ATLANTA - Chicago Cubs manager Mike Quade says Carlos Zambrano cleaned out his locker and "walked out" on the team after giving up five homers in Friday night's 10-4 loss to the Atlanta Braves.

Quade says he is really disappointed in Zambrano and says the pitcher is talking about retiring.

Zambrano (9-7) gave up eight runs and eight hits. The five homers set a career high.

Zambrano was ejected by plate umpire Tim Timmons in the fifth inning after throwing two inside pitches to Chipper Jones, the second going all the way to the backstop. The brush-back pitches followed homers by Freddie Freeman and Dan Uggla.
