Depends on specifics behind your medical degree and the program. Your best bet is to match where you are doing your research fellowship. A number of academic programs will likely interview you, particuarly if you are willing to do a year of research with residency.

In your situation a clinical rotation may help you.
Line up potential research positions and be prepared to do research for another year if you don't match and then re-apply if needed. If you are personable and productive with your research year you've got a shot. But your best chance is to match where you are doing your research fellowship and have another research fellowship lined up just in case.

Good advice!
