I had this exact thought this morning. I'm not the biggest Almora fan by any means, but if Schwarber is out for a long time and Soler and Baez struggle, it'd be fun to throw Almora out there in a few months and just make OF defense a super strength. All around defense, really, with the possible exception of Zobrist.
Markey is definitely one to watch. Tseng at age 21 in Tennessee is worth keeping an eye on too, but he projects as a back-end of the rotation type, right? That's a little hard for me to get excited about. Blackburn is intriguing too, so I guess there are a few pitchers that merit following. Black in his third season in Tennessee is really not of any interest to me. Concepcion has a lot of poor performance to make up for before I pay any attention to him. I'll admit I don't know much about Garner, but the strikeout numbers look pretty nice throughout his minor league career.
Tennessee's pitching doesn't look all that interesting to me, but Candelario, McKinney, Zagunis, Caratini, Hanneman should be worth following, at least until Jeimer and McKinney get promoted.
