PHOENIX -- At the same time they revealed Jarrod Parker will undergo Tommy John surgery and miss the 2014 season, the A's revealed another key piece of their rotation had been scratched from his scheduled Cactus League start on Monday.
Lefty Scott Kazmir is suffering from triceps stiffness, though assistant general manager David Forst talked it down and deemed it "very minor." Still, Kazmir was sent for a visit with Dr. Douglas Freedberg as a precautionary measure.
At the end of the day, manager Bob Melvin said, "There's a chance he could come in tomorrow and say 'I'm ready to pitch.' I'm not sure we'll do that, though.
"Whether it's skip him a complete start and have a bullpen in between, something like that, I'm not sure, but it's all going to do with how he feels tomorrow."
The A's don't anticipate the mild setback to affect his status for the season.
"He probably could've pitched today," Forst said. "There's no reason to push the issue."
Kazmir, who signed a two-year, $22 million deal with the A's this offseason, has thrown seven shutout innings over two starts this spring. His health is paramount to a suddenly injury-ridden A's team.
