I think the excitement has to do with the fact that he's the top prospect in this system and has received quite a bit attention for the past few years. It'd be the same if he were playing at any other position or pitched; we've heard quite a bit about the guy and now we can finally see him in action! Whether or not he succeeds remains to be seen. I'm not going to pass judgment on the guy in his first callup one way or another since we've seen plenty of guys come up, hit really well, and then hit a wall and we've also seen guys who've come up, sucked wind, but was later able to come back and play well. However, I'm still quite excited. :D
