So far Rosario and Buxton have made about 270 plate appearances in Triple A and Kepler about 125. I think these players are receiving minor league lessons and development time at the Major league level. If they all start and play over 130 games and receive over 400 plate appearances this year (2017) at the Major league level, maybe by 2018 we will be able to see what kind of players they really are. Hopefully better development plans are being put in place for the teams future pitching pieces.
