Pettitte's Minor League rehab took him from Tampa, Fla., to stops in places like Rochester, N.Y., and Trenton, N.J., and that travel wore on the 39-year-old left-hander, who can now count on being wherever the Yankees' schedule says he should be.
"That was crazy -- I mean, that was crazy," Pettitte said. "[I said], 'Lord, keep me healthy please,' just because I was flying all over the place. And I was worried about my legs and I was worried about staying loose. I just wanted to stay healthy."
Pettitte said he felt good one day after allowing four runs in 6 1/3 innings to the Mariners, and he is preparing for his next start, scheduled to come at home against the Reds on Friday.
One day after taking the loss in his comeback, Pettitte said his biggest regrets were his pitch selection and not making adjustments quickly enough. But the veteran was pleased with how his nerves evaporated.
"I was just able to settle in and get into a decent rhythm, and I felt just really comfortable out there," Pettitte said. "I thought it would feel a little awkward and another part of me thought, 'OK, you've prepared for this, you know what it's going to feel like.'"
Pettitte said that he and his oldest son, Josh, have been sending supportive text messages to each other. Josh's high school team was knocked out of its playoff series on Friday in Texas, and Pettitte was digitally trying to cheer his 17-year-old up from New York.
After Sunday's start, which included Casper Wells' two-run homer in the sixth, Pettitte said his cell phone flashed to life with the following message: "You looked good out there, Pops. Wells got lucky."
