Long story short, the problem with the pitching in this system is that most of the best prospects haven't even been past short season ball yet. The depth of potentially high quality pitchers in the low levels is really impressive, to boot. I think there are potentially useful pitchers in the high minors...but that's about it. I'll split this post up into three parts: AAA/AA guys, A+/A guys, and the short season names. AAA/AA I don't think there would be a whole lot of argument with naming Trey McNutt as the top prospect in this system. He crashed a lackluster Top 10 last year and drew comparisons to Andrew Cashner. Unfortunately, much like Cashner, McNutt struggled with injuries. Making matters worse, McNutt was not particularly effective when healthy. I don't think the talent is gone, plus he might need an offseason of rest, but his past season makes me wonder if he'd be better suited to relief. If he can stay healthy, he could be a quality #2. After McNutt, there are a lot of guys who could be potentially useful relievers who also have their share of issues: Jeff Beliveau (prone to flyballs and HRs), Rafael Dolis (low strikeout rate), Kevin Rhoderick (great stuff, but wild), and Chris Carpenter (low K rates, wild). The starters are a mix of C/C+ guys. Jay Jackson has fallen off the planet, but he could always rebound. Brooks Raley and Ryan Searle might have some upside left, but probably won't be better than #4 starters. Chris Rusin might end up as the LHP version of Casey Coleman. Alberto Cabrera and Nick Struck were both rushed to AAA and seem like intriguing candidates for relief work. A+/A I'm inclined to agree with toonsterwu that Dae-Eun Rhee is the next best pitching prospect in the system. Most people had left him for dead after last season, but he put up impressive numbers this year across the board, especially in the second half of the season. I'm still a bit concerned about his size and his ability to pitch 180+ innings in a season, but his recovery has gone better than expected. Robert Whitenack will likely end up in Peoria/Daytona on his return from TJS. He already had high quality secondary stuff coming into the season, but the velocity spike was encouraging. Even if he makes a full recovery, I have to wonder if his improved numbers were just a fluke. If it wasn't, he's a potential 2/3. Dallas Beeler also merits some mention here. He was pushed to AA after having a strong start to the season in Peoria, but he clearly was overmatched with Tennessee. Still, he's another year removed from Tommy John Surgery and is young enough to refine his secondary stuff to augment his quality sinker. Assuming AA didn't kill his confidence, I like his potential as a middle of the rotation anchor. Zach Cates is a guy I really like from the Cashner trade. He's relatively new to pitching, has a live arm, and his peripherals were excellent last season. I'm curious to see how he looks next season. After those guys, it gets ugly. The most intriguing names include Aaron Kurcz (potential setup man/closer, but is still a ways away), Jeff Antigua (not a fan; maybe a 4/5 at best), Zach Rosscup (intriguing, but injury-plagued), and Austin Kirk (season fell apart after the no-no). Short Season This is where it gets fun. Dillon Maples received a huge overslot and has a fantastic fastball/curve combination. He's my #3 pitching prospect behind McNutt and Rhee. Not much to say since we haven't seen him in action in the minors, but I'm excited. Ben Wells has slowly been building momentum since the Cubs gave him an overslot bonus despite being a largely unknown prospect out of Arkansas. The sinker is deadly, plus he apparently can rear back for a little extra. He had some issues going deep into games with Boise, but I think he can overcome it with more experience. After those two, there's a glut of really intriguing pitchers. That actually could merit another post altogether. While the Latin American guys (Starling Peralta, Jose Rosario, Amaury Paulino, Luis Liria, Willengton Cruz, Jean Sandoval) seem to have gotten the most coverage here and elsewhere, the Cubs have actually stocked up on pitching prospects from other areas. The 2010 and 2011 drafts brought in Tayler Scott, Michael Jensen, Austin Reed, Arturo Maltos-Garcia, Austin Urban, Tony Zych, and Brian Smith. The Cubs' Asian forays have netted three pitchers who could make a splash in Yao Lin Wang, Jin-Yeong Kim, and Su-Min Jung. As for Hayden Simpson...talk about rotten luck. I'm seriously hoping he makes a full recovery and proves everyone wrong who ripped him when he was selected, but between the mono and the injuries, holy hell does he have a long way to go.
