The former Yankees lefthander revealed Saturday that he doesn't foresee himself making a comeback.
"The desire's just not there," Pettitte said during a surprise appearance at Yankee Stadium. "The same desire that made me go home, you've got to have the desire to play, know what I'm saying? Unless God works a miracle and gives me the desire to do that, I don't see any chance."
On hand to throw the ceremonial first pitch before ALDS Game 2 Sunday, Pettitte, 39, held court with a small group of reporters in the dugout about four hours before the rain-shortened series opener resumed Saturday night. His wife, Laura, will sing the national anthem Sunday.
Peeking out at the infield while Alex Rodriguez and a few others took early fielding practice, Pettitte said he was a bit envious of his former teammates getting ready for the New York playoff atmosphere.
"I don't think I'll ever not miss that," he said.
He just doesn't miss it nearly enough to want to come back, which has made the transition to stay-at-home dad easy. He said he doesn't work out much and the only throwing he's been doing lately has been with a football, to his kids.
Pettitte said the Yankees asked him to return a few times this season to throw out a first pitch or take part in a pregame ceremony, but he said he declined every time. "I felt like I should stay away," he said.
It was only after they asked his wife to sing the anthem that he decided to say yes to throwing out a first pitch. He showed up Saturday well before game time so she could practice before fans entered the stadium, but he said he didn't plan to stick around for the game.
As Laura Pettitte sang the anthem, her husband stood off to the side, watching and holding her purse. He joked to grounds crew workers that a lot has changed in the span of one year. All good, of course.
"My wife let me take my trip of a lifetime," he said. "My dream trip -- went to a ranch in Wyoming, a two-bedroom log cabin. We piled in there like sardines, me and my four kids with no TV. It was the greatest trip of our lives."
Pettitte said he hasn't watched much baseball on television. He's spent the majority of his time this summer with his kids, attending their different sporting events for the first time.
"This whole year, I feel like I made up for a lifetime of everything," he said.
Pettitte declined to answer questions about the Roger Clemens perjury trial, which is slated to begin again in April. Pettitte is expected to be one of the government's star witnesses.
The first trial ended in July when prosecutors showed a video in which a congressman made reference to an affidavit by Pettitte's wife that the judge had ruled inadmissible before the trial.
"I don't want to say anything about that," he said. "Don't even care to talk about it."
