Giants general manager Brian Sabean insists that catcher Buster Posey isn't quite ready for the majors just yet.

Sabean stressed on Sunday that the team's decision on when to promote Posey from Triple-A Fresno has nothing to do with service time.

"Let me dispel all that, all right?" Sabean said. "When we think Posey's ready, just like when we thought (Tim) Lincecum was ready, and this starts from ownership, he'll be in the big leagues."
