John Lackey doesn't view 2017 as his final season.
He was among the National League leaders in innings pitched when he was shelved with a shoulder injury last August.
"I feel great," Lackey said. "I am just playing this year. At the end of the year, if I feel good, I will keep playing."
Lackey is in the final season of a two-year, $32-million deal that he signed in December 2015.
"I have been through a lot of long playoff runs," Lackey said. "I know how to ease into these spring trainings after that. I am not reinventing anything. I have been at it a long time. I just go about trying to fine tune and execute. Until that little time on the DL (in 2016), I felt about as good as I ever did."
