Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

The Tampa Bay Rays

If you were perusing the series in 2015 you would have read this:

The Graduate: Blake Snell (LHP): Control has been Snell’s nemesis throughout his career — save for 2015 — and it came back to haunt him during his MLB debut in 2016. His 3.54 ERA was impressive — and speaks to his raw potential — when you consider his walk rate of more than five batters per nine innings. He’ll also need to better leverage his 6-4 frame to generate more ground balls after being an extreme-fly-ball pitcher in the AL East. Still, Snell succeeds by missing a lot of bats and his struck out almost 10 batters per nine innings in his freshman season. With improved command of his low-to-mis-90s fastball and slider, the young hurler could eventually develop four average or better offerings (He also has a curveball and changeup).

Now on to the new stuff:

First Taste of The Show: Willy Adames, SS: The young shortstop made his highly-anticipated debut in 2018 and performed well — especially given he was just 22. With that said, there is room for improvement after he struck out at a 29% clip. Swing-and-miss has always been a part of his game but he has raw power to tap into and offsets the Ks, to a degree, with a healthy dose of walks, which inflates his on-base numbers. There is 20-homer potential here but he’ll need to get more consistent loft after hitting 52% of his balls on the ground during his debut. Defensively, Adames is expected to move off shortstop and his debut did nothing to quiet the concerns about his fielding.

Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

The Philadelphia Phillies

If you were perusing this series back in 2009, you would have read this:

The Graduate: J.A. Happ, LHP: Happ did not garner a lot of attention while rising through the minors, but the left-hander had a solid rookie season for the Phillies. He did a nice job of keeping runners off base with just 149 hits allowed and a walk rate of 3.04 BB/9 in 166.0 innings. Happ’s strikeout rate dipped from his minor-league average, but it was still reasonable at 6.45 K/9. If he can utilize his curveball more often, it might help him with his strikeout rate, because it will change the hitters’ eye levels. One of the biggest ugly marks on his stats line is the 38.4% ground-ball rate.

Now on to the new stuff:

First Taste of The Show: Seranthony Dominguez, RHP: A mostly unheralded minor league hurler, Dominguez burst onto the scene and overpowered big league hitters with an excellent fastball-slider mix. He also induced a strong number of ground-ball outs and even tossed in an occasional effective changeup. Dominguez’s control wavered at times but most of that occurred in the second half when he might have been getting tired (He walked 16 batters in 24.1 second-half innings, but just 22 overall for the year). The Phillies will look to be contenders in 2019 and this young, hard-throwing hurler has earned the right to open the year as the team’s closer — but veteran reliever David Robertson will be waiting in the wings.

Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

The San Diego PadresIf you were perusing this series back in 2013, you would have read this:

The Sleeper: Matt Andriese, RHP Andriese has been one of my favorite sleepers for a couple years now and he continues to fly under the radar in part because he doesn’t have the electric stuff that gets scouts’ hearts palpitating. His fastball has at least average velocity but it’s the heavy sink that makes it stand out. Andriese, 24, is very close to big-league ready and he could settle in to the role of back-end, innings-eating starter.

Now on to the new stuff:

First Taste of The Show: Joey Lucchesi, LHP: What a year for Lucchesi, a former fourth round pick who needed just over one full year of baseball to reach The Show. He benefited from advanced control while incorporating basically a two-pitch attack with his fastball and changeup. Lucchesi may need to rely on a breaking ball more often in his sophomore season in the Majors now that the scouting report is out on him. He was hurt by the home run ball in 2018 and oddly gave up more homers at home. He’ll need an added weapon against right-handed hitters with almost half the hits against him going for extra bases.

Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

The Texas Rangers

If you were perusing the series back in late 2013, you would have read this:

The Sleeper: Odubel Herrera, 2B: An offensive-minded infielder, Herrera impressed me with his offensive potential in 2012. Unfortunately, he found Double-A to be more of a challenge and the 21-year-old finished the year back in High-A ball after being passed on the depth chart by fellow middle infield prospects Odor and Luis Sardinas. The 2014 season will be a key one for Herrera, who needs to avoid getting completely lost in the shuffle.

Now on to the new stuff:

First Taste of The Show: Ronald Guzman, 1B: The Rangers invested quite heavily in both Nomar Mazara and Guzman during the 2011 international free agency and both made good on their potential… with Guzman taking a little longer to develop. He has a huge frame that generates significant raw power but struggles to reach that pop in game situations. He’s still polishing his eye at plate and produced a modest 33-121 BB-K rate in his big league debut.

The Los Angeles Angels

First Taste of The Show: Jaime Barria, RHP: Barria was a godsend for the Angels’ rotation in 2018. He provided them with almost 130 innings of solid performance — owed almost exclusively to his slider… and a little luck. While he struggled with fastball command at times, Barria flashed above-average control at times, poise and that dangerous breaking ball. Going forward into 2019, he’ll want to try and keep more balls on the ground while spotting his fastball better and continuing to polish his changeup. He’s probably a stretch at anything more than a No. 4 starter but it’s possible he could settle into a mid-rotation innings-eater if he can make good on the above items.

Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

The Cleveland IndiansIf you were perusing last year’s series, you would have read this:

The Sleeper: Nolan Jones, 3B: You haven’t reach much about Jones yet but that might chance in 2018 when he moves up to full-season ball for the first time. The 19-year-old third baseman produced a .430 on-base percentage in 2017 in short-season ball thanks to a 16% walk rate and .317 batting average. The average is due for some regression thanks to his .417 BABIP and 22% strikeout rate but he has the frame (6-4, 190 pounds) and the line-drive pop (22 LD%) to grow into some serious power. Jones looks like a future stud at the hot corner and he has the defensive tools to stick there.

Now onto the new stuff:

First Taste of The Show: Shane Bieber, RHP: Bieber had his ups-and-downs but he held his own during his first taste of the majors better than I thought he would. He chewed up innings and threw strikes — but got too much of the strike zone at times. With improved fastball command, Bieber could develop into a solid mid-rotation starter thanks to his strong breaking stuff and the aforementioned control. His development (along with Mike Clevinger’s) has made it easier for the club to consider parting ways with Corey Kluber or Trevor Bauer.

Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

If you were perusing last year’s series, you would have read this:

The Sleeper: Matt Hall, LHP: Hall isn’t your typical sleeper. He’s not toolsy, especially athletic and he doesn’t eye-popping raw stuff. He’s a small-ish lefty start with a fastball that just squeaks into the 90s at times but he still does a number of things well. His curveball is a plus offering and the heater is good enough to keep hitters honest. He also generates a lot of ground balls despite just 6-feet tall. Some deception in his delivery helped him strike out 149 batters in 138.1 innings. Although he could chew up innings as a starter, Hall could really break out for the Tigers if he gets moved to the pen.

Now onto the new stuff:

First Taste of The Show: Christin Stewart, OF: I’ve been pretty critical of Stewart as a prospect over the past few years but I have give credit where credit is due. He became a better all-around hitter in 2018 while trimming his strikeout rate and not losing any of his power in the process. He looks like a pretty decent bet for 20+ homers and a more-than-healthy on-base rate. With that said, he still carries negative value into the field, and on the base paths.

Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

If you perused the series last year, this is what you would have read:

The Stud: Mitch Keller, RHP: Easily the Pirates’ best pitching prospect, Keller has above-average control, a mid-90s fastball and the makings of developing into an innings-eater. In his prime, he should offer three better-than-average offerings, which will play up even more with his ability to consistently throw strikes. Keller, 21, also induces an above-average number of ground ball outs and allowed just seven home runs in 116 innings in 2017. The right-handed hurler just needs more experience and injuries have cost him valuable innings. After throwing 34.2 innings at the double-A level last year, he’ll return to that level but should see triple-A in the second half. He has the makings of a No. 2 or 3 starter.

Now onto the new stuff:

First Taste of The Show: Nick Kingham, RHP: Kingham missed some valuable development time in 2015-16 due to injuries so he made his MLB debut at the age of 26. And he gave us a valuable lesson on the value of fastball command. The right-handed pitching prospect struggled in that area and ended up giving up 18 homers in just 76 innings of work (2.13 HR/9). Now it’s not all doom-and-gloom for Kingham. He missed some bats and generally showed OK control (highlighting the difference between command and control)… while also looking like a potential innings-eater as a No. 4 starter — if he can solve the homer issues.

Welcome back to my annual off-season series that has a quick-and-dirty review of all 30 minor league systems around baseball. This feature began way back in 2008.

If you perused the series last year, this is what you read:

The Sleeper: Austin Gomber, LHP: Gomber isn’t flashy but he has a chance to be a very good arm for the Cardinals. A 2014 fourth rounder, this southpaw works in the low 90s but he commands it exceptionally well. Gomber, 23, has a chance to have three above-average offerings — including a plus breaking ball. He has a large frame and a good chance to develop into a No. 4 starter capable of hitting 200+ innings pitched. He’ll likely open 2018 in triple-A but could be one of the first arms called up to provide valuable innings.

Now onto the new stuff:

First Taste of The Show: Tyler O’Neill, OF: After parts of three years at the triple-A level, O’Neill finally made his big league debut but he took a step back in his development while doing so. With plus raw power, the young slugger nonetheless felt the need to sell out further to hit home runs. His strikeout rate rocketed to 40%. If he gets back to doing what he does well, O’Neill should be a very good player for the Cardinals with the ability to hit lots of homers and with a strong on-base presence — if he can find playing time. There is no need to send him back to the minors but he is blocked by Dexter Fowler and Marcell Ozuna.

The Yankees system has some very promising prospects and lots of depth but no “can’t miss, impact talent”… at least not yet. There are definitely some candidates to earn that tag by the end of 2019.

Click here for the pre-season Top 10

1. Jonathan Loaisiga | RHP | AAA —> Back in January, I picked Loaisiga as the biggest sleeper in the Yankees system. He made me look good by rising from obscurity, zooming through the minors and even reaching the big leagues. He has the chance to develop three plus offerings but the knock on him is his lack of physicality. And sure enough, he was hurt in 2018 not long after making his MLB debut. If he can hold up as a starter, Loaisiga has No. 2 starter potential. If not, he might end up as a high-leverage reliever.

2. Justus Sheffield | LHP | AAA —> Sheffield is another smallish pitcher but he’s stronger and more athletic than the pitcher above him. He also has a solid fastball-slider combination but the changeup needs a fair bit of polish to become an average offering. Sheffield also struggles with his control at times and I’ve heard that he could stand to be more mature. He gets a solid number of ground-ball outs to go with a health number of strikeouts. I see No. 3/4 starter potential here and he should be ready to pitch out of the Yankees starting rotation in 2019.
