He has a very good approach, his time in Japan shows he has the talent, if he can adjust to the league he'll be worth the money I think (or at least him being on the team). I think the major reason that you don't see him adjusting now is that it's tough to change your swing in the middle of the season. Especially if you've done that your whole life. Mentally I would be thinking that I'm in a slump, if I do something I'm uncomfortable with it will only get worse. If he changes his mechanics in the off season that will give him more time to get mentally adjusted to it.
