This regime has been very reluctant to have rookie hitters on the Opening Day roster, I don't expect any will this year either. As for pitchers, at this point a couple have to make the team, I would put Prielipp as the favorite. I would like to see him, Raya, and Klein get some appearances in the pen at AAA to build up their relieving experience. All of them were quite bad at AAA last year, obviously small sample sizes with Prielipp and Klein.
