Really interesting questions when trying to fill out my spreadsheet when setting the MiLB rosters...
1.) Why on earth didn't they cut Chris Stewart loose when they could have done so owing only 30 days' termination pay??? He has never hit at the MLB level, and with Flowers and Suzuki splitting time there's really no need for him in Gwinnett either. Brantly would make sense as your third option if either of our "starters" were to miss significant time since he actually is an offensive threat, and Scivicque is perfectly ready to split time with Brantly in AAA with Jackson beginning to breathe down their necks.
2.) Why pick Anibel up? Even if you tuck him away in Gwinnett he's simply in the way. He's obviously not good enough to start at any point - as of now he'd probably be #11 on the depth chart (Teheran, Folty, Newcomb, McCarthy, Kazmir, Gohara, Sims, Fried, and Soroka and Allard would all be ahead of him, and you'd possibly go to Wisler or Blair for a spot start before using him). He's not going to make the team as a reliever, and I'd much rather see Lindgren, Ravin, Biddle, Clouse, and Morris getting the relief innings in Gwinnett. As of now, you've also potentially got Hursh, Whitley, Pfeifer, and Carle to use in the pen there.
3.) Haven't they seen enough of Schimpf already? DPete is obviously going to need a roster spot moving forward (whether he breaks camp with the big club or not) and you're adding Acuna two weeks in. Adams' last few games will probably keep him around if they decide to have Peterson get everyday ABs in Gwinnett for the time being, but Schimpf really adds nothing at this point. AA's obviously an Ezequiel fan, and Santana's not going anywhere so Schimpf doesn't really fit even if he can be tucked away - especially with Riley getting the ABs there at 3B and Colon having proved worthy of being added to the 40-Man Roster.
Time to get rid of Stewart, Hursh, Schimpf, and at least one (if not two) of Whitley, Brothers, or Carle and replace them with Brantly, Colon, Peterson, Santana, and an open spot for The Manchild. And that's BEFORE seeing who might become available over the next two weeks.
