GLENDALE, Ariz. -- Zack Greinke, who was set back earlier this spring when he had to get a lubricating injection in his pitching elbow, said Friday he’s not 100 percent sure he’ll be ready for the start of the season.

“We’ll see,” Greinke said. “I’ve thrown enough that I should be ready. If I’m not, it’s not because of lack of innings. It’s just, I don’t know, not getting ready fast enough. I should be good when the season starts.”

If not, the Dodgers could have some pitching-depth worries, considering Hyun-Jin Ryu and relievers Kenley Jansen and Brandon League will begin the season on the disabled list.

Then again, Greinke sounded like he simply was frustrated after failing to get through four innings against the San Francisco Giants Friday night. Dodgers manager Don Mattingly pulled Greinke after he reached his 75-pitch limit and Greinke seemed none too thrilled about it.

Greinke used the words “bad” and “horrible” to describe the outing in which he had trouble locating any of his pitches. Greinke allowed four runs, two earned, on five hits. The outing was prolonged because Carl Crawford dropped a routine fly ball, probably losing it in the lights. Friday’s game was the Dodgers’ second at night in the Cactus League schedule.

“I wasn’t pitching that good the last inning or the inning before. It was pretty horrible,” Greinke said. “Sometimes, you start worrying about the position players chasing after too many balls.”

Because Greinke was one start behind Clayton Kershaw, the Opening Day starter, he won’t have the luxury of a shortened outing in his final spring start. Greinke will pitch the first exhibition game against the Angels April 2 with the goal of throwing 90 pitches.

“After today, I probably need, like, five more starts,” Greinke said.

That’s fine, but unless he starts the season on the disabled list, which seems like a long shot, four of those will be in games that count.
