If I'm Sabean/Bochy, Posey is on my opening day roster. I'd platoon him at first with Huff. He'd also get some AB's in left field and I'd catch him once or twice a week. The guy is too good a hitter to go to Fresno.
He's also too good a hitter, too good good an athlete and not the right body type to stay at catcher. Why (1) limit him to 130 games a year - 10 to 20 of which his bat drags cause he's catching; (2) risk all the injuries etc that come from catching; (3) shorten his career by 3 to 5 years by keeping him behind the plate?
He should end up at either second, third or left - depending on need. Finally, I may have dreamt this - but isn't there another young catcher in the system that the Giants are high on???
