It's obvious that he is not anywhere near 100% physically.
If that's what is holding up his hitting then by all means put him on the IL and he can cheerlead from the bench. The Twins have what? 15 coaches. They should have time to work with him and his swing. If not then send him down and until he gets his swing back. 0 for 29 and counting plus his last 2 months of futility should be enough reason to do SOMETHING.
