i was a bit surprised they started him at AA this year, but his performance (almost .800 OPS in a pitcher's league) has certainly justified their decision. it's kind of dumb calling him up at this point, but i don't think a month and a half in the majors before he's ready is going to ruin him. the angels called up mike trout as a teenager last year, he sucked in his trial, but now he's the best player in baseball history. Trout was also destroying AAA before he was promoted; Machado is doing just OK at AA.
