"I'm not dying to be playing baseball right now," Pettitte said on the Michael Kay Show on ESPN New York 1050. "I'm absolutely loving being home."
When asked specifically by Kay if he will pitch for the Yankees next year or ever again, Pettitte said he doesn't think he will.
"The only thing that would make me pitch again is if I felt this season was over and I felt that I needed to pray and really consider making a decision about changing what I'm doing right now," Pettitte said. "If I missed it so much and I felt in my heart like that was the thing I need to do, I would try to start thinking about it and start considering it again.
"But I'm just telling you right now, I don't think I will ever pitch again."
Pettitte, 39, said during spring training there was "no doubt" he had some curiosity, but he is 100 percent certain that he won't return to the mound this season.
"I'm not playing baseball this year," said Pettitte, who finished his career 240-138 with a 3.88 ERA. "I'm committed to my family. I'm where in my heart I need to be."
Pettitte's words were a little stronger than he used at his press conference prior to spring training. Still, like then, he left the door slightly ajar.
"Down the road again, I'm 39," Pettitte said. "I didn't want to say, 'No, never,' in case I spent this whole season dreading the decision I made."
Instead Pettitte said he runs around with his four kids and wife in Deer Park, Texas. He coaches his son in Pony League and plays on his church softball team. He sounded happy.
"I'm just another dad out there," Pettitte said.
He said he misses taking the mound at Yankee Stadium and the work that goes into it.
"I miss, as a man, having a job to do," Pettitte said.
Pettitte said he had a prior commitment so he won't be at Old Timers Day later this month. He added he wasn't sure he would attend anyway because at 39 he feels he might be too young for such festivities.
