Marlins manager Ozzie Guillen suggested that Josh Johnson may not be completely healthy. ''I just wonder if he's not feeling good,'' Guillen said. ''He says he feels good, but his stuff is not there. I think right now what's killing him is he does not have any command with his pitches.'' In his first six starts, Johnson has a 6.61 ERA and has been a shadow of his former self. PitchFX data has his average fastball velocity at just 92.6 mph.
