The Reds are pitcher-heavy in their prospects, with a good number of both top-tier and mid-range prospects who could be ready for promotion in the next 12 to 18 months.
Update 45 minutes after posting: news from the Reds today has Iglesias getting the nod as a starter over Tony Cingrani. I'm surprised, but it is nice to see Iglesias being taken seriously as a potential starting pitcher. Whether he'll be starting in Cincinnati or Louisville remains to be seen.
Age-24 Pitchersacquired in the Mat Latos trade, and seems very likely to break camp in the Reds' rotation. While he might not have Tony Cingrani's ceiling, I'm pretty comfortable with DeSclafani as the Reds' #5 pitcher this year, and hope he gets that chance.
A few years ago, Daniel Corcino was among the most heralded of the Reds pitching prospects. Unfortunately, regressed badly since then, and seems to be moving toward a career in the bullpen. As a strong arm out of the pen, he does still have a shot at being a quality middle reliever, but I don't hold out a lot of hope that he'll ever provide a lot of value in the rotation.
Daniel Wright was a 2013 draftee out of Arkansas State University, and last year was his first season in as a full-time starter in professional baseball, and had a really nice 6.6 k/bb ratio (8.2 k/9, 1.2 bb/9). He's a bit behind the others in terms of level, but should be in Pensacola at least some time this season.
Michael Lorenzen has been skyrocketing up the depth charts since he converted to a starting pitcher just two years ago, and reports out of spring training have been ridiculous (sitting 97-98 mph in relief, and wowing Bryan Price). He, also, is being talked about as a potential reliever for the Reds this season. Unlike Iglesias, Lorenzen has age on his side, and I personally see little reason to start his service time clock early. If I was confident that the Reds have the organizational will to move a pitcher back into the rotation after having strong success in the bullpen, I might think differently. But I just don't trust them to do it.
Amir Garrett, a former two-sport player, has quit basketball and is now focusing on baseball full-time. He's making strides as a result. Nick Howard and recently-acquired Jonathon Crawford are both 1st-round draft picks with good performances behind them so far. And for some reason, Steamer didn't make a projection for Wyatt Strahan, but he, along with passed-through-waivers Ismael Guillon, is distantly behind the other guys in this group.
Sal Romano, who was also in the Dayton rotation last year, took a similar step forward, with even better peripherals than Travieso. As a result, he shot up the prospect rankings, and is now seen as something of a sleeper. Both are still very young, and provide some much-needed depth in the lower minors for Reds pitching.
