I'm not saying he's overmatched, but the lack of contact is a major concern. He's doing very well for a 19 year old in full season ball, but I don't see how promoting him to Fort Myers fixes any of his issues. You keep mentioning his 15% walk rate which is fantastic, but his strike outs are a concern. First off Machado is a middle infielder (maybe 3B if he gets too big) so I don't see how mentioning his OPS in comparison to Sano's means anything. Whatever the O's wanna do with Machado is their business, hell the Mets have 19 year olds in AA. Doesn't mean it's the right gameplan. Over the last 10 years the Twins have produced Span, Morneau, Mauer, Revere, Ramos, Ploufee and a few intresting position players in the minors. Maybe that's not the sexiest list of players, but maybe the slow promotions has worked a bit. I agree with you that the Twins haven't developed players as well as they should over the last 5 years, but I don't see how pushing kids who clearly still are rough around the edges fixes that.
