"What if he hits badly? You would still keep him in, jeopardizing the Giants playoff chances?"
For Christ's sake man...are you really serious with these questions?
People want to see Belt get some consistent playing time in order to see if he can adjust to the big leagues and bring some of the success that he had at every level of the minor leagues. It's not complicated.
People don't want to see him jacked around and sent down and called up 3 times like last year. People don't want to see him get benched because he doesn't go 4 for 4 every night. You really think that if Belt got starts this season like Huff did last year and failed we'd all still be screaming for Bochy to play him every day? Belt never had 100 at bats at one time before being sent down and finished the season with less than 200 ABs total. This year he got 11 at bats before being benched.
I know there are some here that feel like he should have lit the world on fire in those limited opportunities and since he didn't he's just not good enough to get playing time over the great Aubrey Huff or Nate Schierholtz. They'd argue that those limited opportunities are all a 22 year old player should receive to show what he can do and succeed. Then there are those of us who contend that it may take a young kid like Belt with all of his 2 years of pro ball a little more time to get adjusted. Some of us point out that there have been many good ball players that needed time to find their groove and gain success. Of course, somehow we're whiners for feeling that way.
It's funny to read all of these posts about people that "want to put Belt before the team", "think Belt is the next Albert Pujols", "think Belt should be babied and shouldn't have to earn his playing time" etc etc.
None of it is based on reality. People want to see if this kid has what it takes by giving him regular starts. Belt has the kind of upside that could help this team immensely if he can reach it. Huff will not be a Giant this time next year and he's not the Huff of 2010. He's the one who's had a full opportunity to prove that. Regardless of a track record he's the one that has been given the long leash and he choked on it. It makes a little bit of sense to see what Belt's got now and to know if he can be the everyday first baseman next year. If there were some young stud that Belt would be blocking people wouldn't be calling for him to start. That person simply doesn't exist.
