Veteran left-hander Andy Pettitte hasn't yet decided if he will return next season or if he will retire, according to the website of a Houston television station.

While attending a charity golf tournament in Houston this week, Pettitte told khou.com that while he had no timetable for deciding, if he does ultimately decide to return next season it will be his last.

"I'm just going to wait and see what my heart wants me to do," Pettitte said. "Right now, I can tell you my heart's right here in Deer Park, (Texas). If something happens and I play one more year, that would be it. It would be one more year and that would be it."

Pettitte, who will turn 39 next season, continues to be an effective Major League pitcher, having gone 11-3 with a 3.28 ERA for the Yankees in 2010. The southpaw cited his desire to spend more time with his family as his primary reason for considering calling it a career.

"My kids are getting older and one's going to be out of high school real soon, and I'm not going to miss his whole high school," Pettitte said. "I want to be able to be here and see some of his stuff, and you can't see his stuff playing Major League Baseball. I just feel like I have a big responsibility here. I have three boys. I feel like I need to be around and raise them, and I feel like we're getting to that point where it's the crucial ages of their lives that I need to be around a little bit more."
