This year, things look different in the minors. The Brewers dropped 16 spots in the Baseball Prospectus organizational rankings, due as much to the underperformance of top draft picks (Trent Grisham, Corey Ray) as the big Christian Yelich trade (which sent away three of the highest ceiling prospects in the system, even if they were risky ones). Looking through the affiliated clubs’ opening day rosters, one can get the feeling that the system is less exciting than the 2016 and 2017 versions; or, if the system remains exciting, it’s exciting because of some of the very raw, underdeveloped talent in the club’s low minor affiliates, rather than the advanced affiliated prospects. Nevertheless, extremes abound for this system, as the Brewers are also using their most advanced affiliates to store MLB 40-man roster players (prospect or not).

Below is a list of the 2018 Top 10 Brewers Baseball Prospectus prospects, as well as eleven additional prospects that were covered in the list, plus Jordan Yamamoto (who was also included in the Yelich trade package). I’ve assembled their 2018 age, assignment, as well as the Overall Future Potential role and likely projection for each player (where available). In the case of the eleven additional prospects, only one role or outlook was typically provided by the scouting team, whereas a “high percentile” and “likely outcome” were both provided for the Top 10.

A few quick notes:

• Yesterday, Brewers beat reported Adam McCalvy reported that Keston Hiura will begin the season as a DH due to some elbow soreness experienced while throwing during camp. This is one key reason that fans need to slow the brakes on Hiura Hype, as the DH-risk remains real, and the highly regarded second base prospect really is not a professional second baseman yet; until that is proved otherwise, one also has to wonder if he will end up in left field or as a DH.

• Anchored by Corey Ray and Trent Grisham, the Double-A Biloxi outfield might have the best bounceback tandem in the system. It’s so easy to find critiques with each player’s development thus far, and yet here we are with both players working a level away from the MLB at very young ages. If either play puts things together at this level, MLB role projections could quickly come into focus.

• Tristen Lutz and Carlos Herrera both debut in full season ball, making A Wisconsin one of the most exciting teams in the system. That team is loaded with sleepers, as well as some prospects like Lutz and Herrera who are looking to define that top percentile MLB role and the risk associated with it.

Of course, this list does not even cover 10 percent of the Brewers system, so while assembled minor league assignments, I collected ten of my favorite “deep system” prospect picks. Here I picked one arm and one bat from each level:

A few quick notes on my favorites:

• I will continue to write about Demi Orimoloye as long as he stands outside of typical top prospect debates, because in terms of having tools and waiting to hone the baseball aspect of the game, there’s probably not a higher return in the system (of true extreme risk players) than Orimoloye putting it all together. Watching his second turn at Wisconsin could demonstrate how likely this type of scenario may be, or how risky Orimoloye really will be.

• I picked a few long development and “old” guys in the system because there are simply some very interesting underlying performances (Daniel Brown, Nelson Hernandez) and tools (Luis Aviles) in some of these minor league grinders. Hernandez and Aviles have not necessarily had easy and clear development paths the last few years, but Hernandez is making his full season debut at a reasonable age overall, and Aviles has always simply been about whether the bat comes around. In 2016, the glove was the same story with Aviles in midseason Wisconsin Timber Rattlers coverage, so there’s a question about how long it’s worth hammering home this scouting line, but here we are with another chance for Aviles to prove himself.

• In contrast, it is worth emphasizing that an extremely athletic, ex-Top 10 Prospect like Tyrone Taylor remains (very) young for Triple-A, and is now working a level removed from the MLB. While there are undoubtedly reasons that Taylor’s prospect star has fallen, the recent identification of mechanical adjustments to unleash MLB stars should underscore that where talented, athletic players work to fix their approach, even a seemingly pedestrian profile can emerge as a productive MLB player. Taylor has the athleticism to work as an MLB depth outfielder, now it is worth seeing whether the bat follows at the most advanced level.

• The aggressive Thomas Jankins assignment is probably my favorite for the 2018 season. At BP Milwaukee last season, Kyle Lesniewski profiled Jankins as one of a handful of intriguing late round arms in the Brewers system. While Jankins might not have the “big stuff” profile of a Trey Supak to dream on, the righty has a command profile that matches some of the analytic trends emerging in the Brewers big league rotation (Zach Davies) and offseason acquisitions (Wade Miley).

Finally, throughout the minor league season, remember to support minor league players in their quest for a living wage, and continue to discuss alternatives to the current format of minor league compensation upheld by Major League Baseball. Prospects deserve transparent press coverage and support from fans, and part of this support should include transparency about MLB efforts to openly suppress pay of their affiliated professional players. It is worth emphasizing that the MLB is codifying their position of exploiting minor league players at a time of great wealth for the sport, as evidenced by the extra $50 million MLB Advanced Media revenue payment paid to every team; in an elite revenue industry, why are many minor league players struggling to earn even $7,000 a year for their professional efforts?

Continuing age-based analysis of minor league statistics, the 2016 Midwest League could be the most interesting case yet. Unlike the Southern League or Pacific Coast League, the Midwest League featured a group of three different age levels with similar production, and two adjacent age groups that did not fall far. From age-21 to age-22 to age-23 players, Midwest League bats slashed .245 / .316 / .356, .249 / .318 / .352, and .247 / .317 / .353, respectively. On the outskirts, age-20 batted .249 / .307 / .367 while age-24 batted .252 / .315 / .333, giving the league an expansive middle ground of 345 players that can be judged by very similar production standards.

One might ask whether this reflects the nascent stages of minor league competition, perhaps where players may be closer to the same development curve, thereby exhibiting less stratification among minor league players. Perhaps Class-A is the first level at which “organizational lifers” emerge, or players hit their first professional ceiling and stick around for a year or two before heading to their next career. It would be worthwhile digging into a scouting explanation for this phenomenon, in order to see how the physical tools relate to the statistics; perhaps everyone (or almost everyone) at Class-A is still learning the strike zone, or pitch recognition, or some foundational trait that places the vast majority of players on the same level.

There are a number of notable bats that defined the Timber Rattlers in 2016. Isan Diaz produced one of the best seasons at the Class-A level, and although he did not win MVP, he certainly has the performance level worthy of consideration. Lucas Erceg also stormed the league out of the 2016 draft, demonstrating a completely different developmental stage (relatively polished college draftee) than Diaz. Along with Diaz and Erceg, several depth players produced interesting or good seasons, giving fans and writers more players to think about and watch during the 2017 campaign. Perhaps no one will be more interesting to follow than Monte Harrison, whose statistical line was damaged by a rough April and early-May, and whose hot streak was cut short by injury. Harrison has shown flashes of “putting it together,” so it will be crucial to see how he returns from injury.

Down in Florida, the Brevard County club had a rough season, mostly due to the bats. This level lagged behind in the system during 2016, and unfortunately, even age-based statistics do not allow one to reconsider many gems.

It is worth noting that Corey Ray produced a fine campaign, based on his age level and the fact that he was making his professional debut in an aggressive assignment. While Ray’s surface stats of .247 / .307 / .385 does not look very good, age-21 players in the Florida State League were notably worse than that production level, allowing one to see that Ray showed solid hitting, discipline, and (especially) strong isolated slugging. Even if one follows scouting reports to raise some questions about the hit tool, there is a sense that Ray’s tools are already showing up in his stat line, even if that line is depressed by his environment.

Once fans come to Wisconsin for Isan Diaz, they can stay for other intriguing positional prospects, as the club is beginning to shape out its 2014 and 2015 draft legacies. At this turn, the low minors arms may be ahead of the low minors bats in the Brewers system, and Wisconsin arguably reflects that balance. Prospects such as Diaz, Trent Clark, Monte Harrison, Jake Gatewood, Lucas Erceg, and Troy Stokes, Jr., have a collection of solid tools, but their profiles thus far grade slightly behind their pitching teammates in terms of impact. Beyond these well-recognized names, one might even dig for some sleepers at Wisconsin, although the caveat about leaping to the next levels to define or change a ceiling apply here, too.

The lack of clearly-defined ceilings for several Wisconsin bats is not necessarily a concern at Class-A, since these players must advance through the next A-level club and make the leap into the upper minors before the probability of their respective ceilings becomes even clearer. Below, BaseballProspectus scout and writer James Fisher notes that a couple of Timber Rattlers have defensive profiles that are awaiting a step forward from the bat; there are even some prospects that need additional looks. In this sense, the 2016 Timber Rattlers effectively define (and headline) the Brewers loaded organizational depth even where they fail to define better than average MLB ceilings.

Midwest League Environment
Judging minor league players by their statistics is a tricky endeavor. First and foremost, since players are developing their tools at the minor league level, their actual performances on the field are not always indicative of their MLB ceiling or potential future value. Furthermore, if a player is honing in on one specific area of their respective toolbox, other areas of their performance may suffer in their statistics. In this case, it is somewhat possible to have a player move forward without necessarily showcasing each of their tools in their statistical record. Age and development levels can also impact a player’s performance; this is especially true in the Midwest League, for instance, where a 19-year-old performing in their first full season of professional play after being drafted out of high school would be expected to perform at a different level than a polished college player working in their age-21 or age-22 season.

With that in mind, one way to consider minor league statistics is by judging each player within their specific context of age, opposition strength, and league strength. For example, the Midwest League is a much more depressed environment than the Class-A counterpart South Atlantic League, which impacts how one can read statistics. League statistics were compiled for the first installment of this series, August 20-22, 2016:

With this in mind, I developed two charts to judge batting and pitching context for the Midwest League. 218 Midwest League batters have had regular play after the June draft or throughout the season, with a base threshold of 130 PA:

The 90th percentile is most elite, meaning that a player facing .661 opposingOPS pitchers is facing tougher competition than 90 percentof the league, or a .300 TAv is better than 90% of Midwest League regulars (i.e., the other way around, that player would be in the Top 10 percent of production). In terms of age, the 20th percentile is old for the level, the 90th percentile age is extremely young.

For pitchers, 228 arms have worked 30 innings or more:

In this case, a 2.55 FIP is better than 90% of regular hurlers, and a pitcher that faces a .682 opposingOPS is facing tougher competition than 90 percent of the Midwest League regular arms. One can note that comparing the full Midwest League with “regular players,” regular batters (130+ PA) have posted a much better median TAv than the league median (.252 TAv for regulars, .243 TAv for the full league). So, one might expect a regular batter to have a better performance in this sense (depending on their age and strength of opposition, of course).

Wisconsin Batters Scouted
The following entries are built from BP James Fisher’s scouting notes, which were compiled during an early August series in Appleton. All statistics compiled on August 24, 2016.

Catchers
Max McDowell (80th percentile TAv, 50th percentile age, 50th percentile competition): McDowell is a large framed catcher with strength throughout. At the plate, he starts with an even stance and rests the bat on his shoulder before moving his hands up to his ear. Has slightly below average batspeed and doesn’t recognize spin. Behind the plate, McDowell has a low seat with a quiet frame. He struggles to handle quality stuff, with changeups especially giving him fits. Boxes plenty of balls as well as passed balls through the wickets. Throws well with 1.93-1.98 pop times, and the footwork helps the arm play up a touch. AA/AAA Ceiling. Wisconsin Note: McDowell has produced an excellent TAv at a median age, and against median competition.

Natanael Mejia (below 20th percentile TAv, 20th percentile age, 90th percentile competition): Large, soft bodied catcher. Mejia starts from a slightly open stance and high hands. Below average batspeed and limited contact ability. Defensively, he moves ok behind the plate, but lacks the ability to handle quality stuff. A Ceiling. Wisconsin Note: As a notably old player, Mejia faced the most difficult competition and produced a poor TAv.

Infielders
Luis Aviles (50th percentile TAv, 60th percentile age, 30th percentile competition): Aviles has a lean athletic frame with wiry strength throughout. From an even, upright stance in the box with his hands at his shoulder, Aviles has average batspeed but struggles with pitch recognition at present. Aviles can really pick it in the field. He moves side-to-side well and has body control for short. The arm is a 6, with true carry through the bag and ability to make throws from different angles. At this point, Aviles is a defensive specialist that lacks bat to ball. AA/AAA ceiling unless light comes on with bat. Wisconsin Note: Aviles is a slightly younger than median player with a median TAv against relatively weak competition.

Isan Diaz (80th percentile TAv, 90th percentile age, 40th percentile competition): Athletic, medium framed second baseman with premium offensive toolset. At the plate, Diaz combines a quality bat path with a slight uppercut. It’s a loose, easy swing with above average batspeed and barrel awareness. Diaz understands his weight transfer, at times making hitting look easy, and he really lets his hands do the work. The ceiling is a 6 hitter with at least average pop. In the field he is just a step short for shortstop and has trouble going right. At second his feet will be average and the arm will play.
MLB Role: First division regular with all-star potential.
Wisconsin Note: Diaz is among the youngest players in the Midwest League, and produced a notably above average TAv against near-median competition.

Lucas Erceg (90th percentile TAv, 60th percentile age, 30th percentile competition): Tall, lean framed third baseman with feel to hit and plus arm. There is room for strength projection here. At the plate, Erceg starts tall with slightly open stance and hands at his ear, combining 6 bat speed with hands that work and a loose swing. Can get long at times, but makes adjustments. In the field, he has soft hands and enough range for third. Erceg’s arm is a weapon.
MLB Role: Regular at 3B.
Wisconsin Note: As a relatively young player facing relatively weak competition, Erceg is producing an elite TAv.

Jake Gatewood (30th percentile TAv, 80th percentile age, 40th percentile competition): Gatewood is a tall, lean framed infielder with plus power and arm strength. At the plate, he starts from an even stance with his hands at his shoulder, and has average bat speed. However, Gatewood struggles to make adjustments, and spin will always give him trouble. The raw power is a 7, but he lacks enough contact to get there. Gatewood is mixing time between third and first at present with enough range and arm for third, but he needs to hit. AA/AAA ceiling unless bat takes big jump forward. Wisconsin Note: Gatewood remains notably young at Class-A, and is producing a below average TAv against near-median competition.

Jonathan Oquendo (below 20th percentile TAv, 80th percentile age, 80th percentile competition): Tall, lean frame with athleticism. Oquendo starts at the plate with an even stance and his hands at his shoulder. The bat path is inconsistent, but he does have average batspeed. Oquendo doesn’t like spin and is susceptible to it on outer half. With long lanky strides, he is a slightly below average runner. DH’ed in my look. Hold on ceiling until further looks. Wisconsin Note: Oquendo is a notably young player facing very tough competition, and is producing a poor TAv.

Alan Sharkey (below 20th percentile TAv, 50th percentile age, 50th percentile competition): Medium, strong framed first baseman with strong lower half. At the plate Sharkey’s bat speed and pitch recognition are lacking. There is power potential from strength in frame, but he won’t make enough contact to reach it. Average at best at first base. Has reached ceiling. Wisconsin Note: As a median age player against median competition, Sharkey posted a poor TAv.

Outfielders
Carlos Belonis (below 20th percentile TAv, 60th percentile age, below 20th percentile competition): Tall, lean framed outfielder with athleticism. Belonis starts with a closed front foot and his hands above his head at the plate, and he strides closed. He has average bat speed, but an inconsistent swing path and approach leave him behind. He often guesses on pitches and huntsfor fastballs because he struggles with spin. In the field Belonis has an average arm and enough athleticism to handle a corner outfield spot. A/AA ceiling at best. Wisconsin Note: Belonis faced weak competition and was relatively young for Midwest League, and he posted a poor TAv.

Trent Clark (60th percentile TAv, 90th percentile age, 40th percentile competition): Strong, medium framed, athletic outfielder with plus tools at the plate and the field. Starting at the plate with a slightly open stance and his funky hands at shoulder, Clark’s plus batspeed and a consistent bat path lead to loft. The power will come as the plate discipline does for Clark; there is plenty of strength and batspeed to project average power. In the field he is still recovering from leg issues, but is running okay (4.10, 4.12, 4.38, 4.12, 4.44). Handles center at present with solid jumps and routes, but most likely a corner outfielder with enough arm for right.
MLB Role: 4th OF/Regular.
Wisconsin Note: Clark is among the youngest players, and posted a slightly better than average TAv against near-median competition.

Brandon Diaz (below 20th percentile TAv, 60th percentile age, below 20th percentile competition): Diaz is a small framed, athletic outfielder with batspeed and defensive tools. Starting at the plate with open stance and hands at shoulder, Diaz has average batspeed and some feel for the barrel. Runs okay in left and has an average arm. Only 3 AB’s. Need more of a look. Wisconsin Note: Diaz has a poor TAv at a relatively young age facing weak competition.

Troy Stokes Jr (80th percentile TAv, 80th percentile age, 30th percentile competition): Stokes is a small framed athletic outfielder with strength throughout. Physically maxed out. At the plate he starts with an even stance and his hands at his shoulder, and gets into a slight bat wrap at times and messes up his timing. Stokes has average bat speed but struggles with pitch recognition. Isn’t a burner with 55 run times. Interesting routes in LF at times but is solid. Tweener 4th outfielder type when all is said and done. AA/AAA ceiling. Wisconsin Note: Stokes is notably young and facing relatively weak competition, and is posting a notably above average TAv.

DL:
Tucker Neuhaus (90th percentile TAv, 60th percentile age, below 20th percentile competition); Juan Ortiz (below 20th percentile TAv, 60th percentile age, below 20th percentile competition); Monte Harrison (20th percentile TAv, 80th percentile age, 50th percentile competition)
