Never found Gamboa's, but he himself claims it's 230-15 if that's any good. Groves was 66-10. Unfortunately haven't been able to find DeGale's or Sutherland's.
DeGale had his full record on his site before (listing every opponent he had fought), but it seems to have been taken down for some reason when the site was updated :conf He had something like a dozen losses and about 60-70 wins if I remember correctly.
