Tyler Austin .235/.309/.311, 4 HR, 27 RBI, 8 SB, 81/26 K/BB, 299 PA
It seemed like Austin had turned a corner last year, but in 2015 the bottom completely dropped out for him. He was such a non-entity at the plate this year that he was eventually demoted in order to get him out of the way of better players. He was designated for assignment, but at only 24, the organization is likely not completely done with him yet.
Greg Bird .301/.353/.500, 6 HR, 23 RBI, 27/11 K/BB, 150 PA
In his age-22 season, it didn't seem like he'd get too much time in Triple-A, but he dominated there and ended up becoming an integral part of the major league team in the second half of the season.
