In 2011, Jose Altuve got 35 games in AA before being called up by the Astros in late July or Early August. Starlin Castro only had 56 games before the Cubs called him up. Christian Yelich only got 49 games in AA before he was called up. Justin Upton only had 71 games in AA before he was called up. The Giants were good, but Buster Posey got 7 games with the Giants in 2009 after only 35 games above A ball (he went to AAA with no AA in between). He hit .118, so he wasn't there to help the team, just to get a cup of coffee in the majors. Thats probably the closest thing to Buxton as we can get. I don't think he'll get a September callup. It would be very unusual if he did, but not unprecedented. I think a more likely career path is like Andrew McCutcheon. A month in AA this year and next year, then the rest of next year in AAA, then start 2016 with the Twins.
