Pettitte was 11-3 with a 3.28 ERA in his last season, but was plagued by injuries. He feels he benefited from the time off.
"When I retired, those last games I pitched in the postseason, my groin and my lower back were hurt," he said. "Those are the things I would be concerned about, if there was a concern. I've had 16 months for those to heal."
Pettitte is one of five starters looking to fill three rotation spots behind CC Sabathia and Hiroki Kuroda. He put a lot of thought into this decision and promises no regrets.
"It's a great opportunity. It's a great challenge," Pettitte said. "No matter what happens, I prayed about the decision with my family and my kids for a long time and we feel it's the right thing to do."
