Carlos Zambrano apologizes for past

CHICAGO -- After leaving the Cubs' clubhouse in a rage last August -- an incident that effectively ended his career in Chicago -- Carlos Zambrano took the blame for letting the franchise and the city of Chicago down on Tuesday.

"I apologize for anything that I did," said Zambrano, who was dealt to the Miami Marlins in the offseason. "The only thing I wanted to do in Chicago is win, and once again, I apologize to the Cub fans and the people here that treated me good. They deserve an apology."

The former Cubs ace pitched 10 years with the club before he was traded for right-hander Chris Volstad. The Cubs are paying all but $2 million of Zambrano's $18 million dollar 2012 salary.

Returning to Wrigley Field for the first time since he left the team on Aug. 10, 2011, was very emotional for the 32-year-old pitcher.

"When I got to the light between Addison and Clark, I saw Wrigley Field and I said to myself 'I can't believe it.' " Zambrano said. "People welcomed me from the office and from the team with a hug, and it was pretty emotional."

The fiery pitcher stated that his faith has allowed him to be honest with himself and accept human failure in himself and others around him.

"When I was here, I put too much pressure on myself trying to do too much," Zambrano said. "I know I have to play (better), and I did not do that in the last two years. I have to say out of 10 and a half years in Chicago, eight and a half were good. The last two, I was frustrated and out of control, but that is in the past."

Zambrano will not pitch during Miami's three-game set at Wrigley. He admitted that fact was a relief.

"To be honest, (I) did not want to pitch here -- not this year," he said. "The time will come that I come back, but it will be emotional, and it would be something weird to come out of the right-side dugout."
