This is almost exactly what was said about Lawrie not being ready for MLB. Harper's promotion is all about his talent, not his MiLB stats. I didn't see a single person say Lawrie wasn't ready last year, I didn't read one single person make that comment on this forum or the fantasy forums. People were worried about his BB rate to start the year at AAA but by the time he was called up that had passed. I think Trout is ready too, he had some major league experience last year and was killing AAA this year. Harper should be in the minors for another half season and the only reason he was brought up was because they are off to a hot start and want to get fans in the seats, I doubt it is because they think he will actually produce right away.
