If we still have need to send Kobernus to AAA 4 years from now, he isn't gonna make it anyways. He is (almost) 25 already.
He has an OBP of .374 which brings his career number to .322. Coupled with walk percentage below 5% and an ISO of .082 in his best ever showing, and you think he's ready. You want to burn his most valuable asset, which is his options because there is nothing in his stats that remotely suggests he's ready. It's down right idiotic to suggest two major league franchises have come to the same conclusion are wrong.
