His effectiveness at ML level is still an open issue. He could be very, very good or bad. I do think an audition is warranted. My hunch is that the Reds will take a look at him during the next home stand, probably in the Florida games. I really don't think the Reds will be asking much more than heat. If he remains composed and pitches well, they will take him west. Otherwise, there are too many important games and other pitchers that are doing well to afford the luxury of a ML learning curve for Chapman at this juncture.
