After giving up five home runs in a 10-4 loss to the Atlanta Braves and getting ejected for throwing at Chipper Jones on Friday, Zambrano cleaned out his locker and told trainers and clubhouse people during the game that he was "retiring."

Zambrano's agent Barry Praver told ESPN The Magazine's Buster Olney that the Cubs were told within two hours after Friday's game that Zambrano "definitely" wasn't retiring. Praver said Zambrano made private emotional remarks to club staff and returned his things to his locker late Friday night.

Praver told ESPNChicago.com that the Major League Baseball Players Association will file a grievance on Monday due to the severity of the punishment.

"His actions last night are very detrimental to his teammates," Hendry said. "There's not much worse than running out on your teammates and announcing your retirement."

Hendry said he apologized to Braves general manager Frank Wren for the actions by Zambrano, which tarnished former manager Bobby Cox's night. The Braves retired Cox's No. 6 before the game.

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

"It was uncalled for, the pitch to Chipper Jones," Hendry said.

"I feel that anything at all to detract from Bobby Cox's night other than usual competition is totally intolerable."

Asked if he knew where Zambrano was on Saturday, Hendry said, "I have no idea."

Jones said Hendry's comments were "a class move. I appreciated it."

Added Jones: "I like Carlos. I've always liked Carlos. He's an intense competitor. Unfortunately, sometimes that hurts him."

Cubs pitcher Ryan Dempster wasn't so understanding.

"He's made his bed. Let him sleep in it," Dempster said.

"It's not like it's something new."

Outfielder Marlon Byrd said he talked with Zambrano.

"He said that he's doing better today," Byrd said. "That's it."

Asked about Zambrano being placed on the disqualified list, Byrd said: "That's business. They have to do what they have to do."

Cubs third baseman Aramis Ramirez said Zambrano would be welcomed back by his teammates, but only if he made changes.

"If he changes his attitude, he's more than welcome," Ramirez said.

"He's got to think a little bit more. He's one man. It's not just one time. A lot of people have tried to help him. He won't let them."
