Instead of getting to watch Travis d'Arnaud, Buffalo fans will get Anthony Gose, who returns to Triple-A. He can be very exciting to watch, but the reason he's back there is to work on hitting lefties.
Simon Castro, Andre Rienzo, and Charlie Leesman make for an interesting rotation, and Jared Mitchell can be exciting in the outfield. Trayce Thompson will provide some power, but will have to cut down on the swins and misses if he wants to be able to use it in the majors.
Perhaps no prospect in the IL will be more polarizing than Trevor Bauer, who is working on new mechanics. How much time he spends in Columbus will depend on how well he takes to the changes.
The Bulls feature a starting rotation that may actually be better than some of the bottom-end major league rotations, including prospects Chris Archer, Jake Odorizzi, Mike Montgomery, and Alex Colome. They also feature Wil Myers in the outfield, one of the best hitting prospects in the minors, and former first overall pick Tim Beckham.
Despite graduations to the majors and trades, the Braves still have some talent in Triple-A. Former first-rounder Sean Gilmartin headlines the rotation while Joey Terdoslavich should be the team's most potent hitter while learning to play the outfield.
The best player in the IL, and certainly the best pitcher, should be Gerrit Cole, who won't be in the league too long after Memorial Day. Tony Sanchez will get one more chance to prove he's more than a backup catcher and Kyle McPherson will stay ready for when the Pirates need pitching depth in the majors.
Lehigh Valley (PHI)
Darin Ruf will try to back up his breakout 2012 season while also trying to learn how to play a non-disastrous outfield. Ethan Martin has an exciting arm and will try to stick as a starter, and Tommy Joseph has leaped over Sebastian Valle on the organizational depth chart behind the plate. Plus they have video game urinals in the men's rooms.
Louisville Bats (CIN)
The Reds say that Billy Hamilton will spend the entire season in Louisville so he can learn the nuances of center field, but we'll all believe it when we see it. Tony Cingrani will work as a starter in the minors, but he'll get called up to bolster the Reds bullpen at some point in the season.
Allen Webster would have been the talk of Red Sox spring training had it not been for Jackie Bradley, and he should be the talk of Pawtucket with his power arm. It will also be interesting to see how Bryce Brentz comes back from shooting himself in the leg, literally.
Kyle Gibson will get his arm in shape and work on regain his command post-Tommy John surgery until he gets the call from the Twins. Oswaldo Arcia is a talented but still raw outfielder who factors into the Twins rebuilding plans.
Beware of errant fastballs from Dellin Betances, who returns to Triple-A after a disastrous stretch there last season. Melky Mesa was in the running to fill in for Curtis Granderson but needs to refine his offensive game.
I give Nick Castellanos a hard time, but he's still the Tigers best prospect. He'll be working on his outfield defense. Bruce Rondon will be closing games for the Mud Hens and working on his command in hopes he can close games in the majors this fall.
