I'd say you just need to be patient. A lot of your players still haven't gotten started yet this year. Also you may want to try trading your 1b since you are at a position of strength there; Butler, Gonzalez, and Fielder can't all play at the same time. Hence one is expendable! Maybe try to get another OF or something, maybe SS. I don't think Wells will keep this up all season.
Also, I may try to pick up a couple high K/9 relievers as you should try to stack up on K's. You probably won't see very much out of wins but saves are pretty easy to come by IMO. Just a thought. Of your pitching you have some less effectives ones (for example Kuroda does not generate a lot of K's) so you may want to look into that too. All in all, by the end of the year your offense should click so I'd stay patient and don't panic drop anyone!
