Jose Berrios has a 6.75 ERA. His FIP is 5.63. He’s walked 16% of the batters he’s faced this season. He’s averaging more than 20 pitches per inning, and in two starts he has completed just 9.1 innings. He also has three good, major league-quality pitches with the potential for a fourth. He’s struck out more than 30% of the batters he’s faced. He could win Rookie of the Year, and — with arguments to come from Lucas Giolito, Tyler Glasnow, Alex Reyes, Blake Snell, and Julio Urias — he might be the most exciting pitcher to make his big-league debut this season.

Berrios doesn’t turn 22 until the end of the month, but he has ridden a quick and steady ascent to the majors. In 2014, he dominated High-A and held his own in a handful of starts at Double-A. Kiley McDaniel ranked him the 24th-best prospect in baseball during the 2014-15 preseason before he proceeded to mow down opponents in Double-A and Triple-A, striking out more than 25% of batters at both levels and walking less than 6% of them. Berrios entered Spring Training with an outside shot to win a starting job, but struggled with command in both his major-league and minor-league games.

In three minor-league starts this year, Berrios still produced his share of walks. But also struck out 20 of the 66 batters he faced and allowed just three runs, earning a promotion when Ervin Santana hit the disabled list. His first two starts have been a mixed bag, featuring both flashes of the potential that make him a top prospect with a comp to Pedro Martinez and show how he can be successful in the big leagues, but also an inability to consistently attack hitters in the strike zone, leading to unfavorable counts and walks.

The chart below shows league-average plate-discipline numbers as well as Berrios’ own numbers over his first two starts.

As Susan Slusser with the San Francisco Chronicle reported on Wednesday, Sean Manaea will be called up to start Friday’s game in Oakland against Mike Fiers and the Houston Astros. Manaea made a decent case for making the rotation out of spring training, tallying 16 strikeouts in 14.1 innings, but the seven walks allowed over the same period gave the A’s enough reason to start him in Triple-A Nashville.

Across three starts in Nashville, he has been lights out on the mound. Only three runs have crossed the plate against him in 18 innings pitched, while 21 batters have struck out and just four have reached via free passes. That level of performance was enough for Oakland to feel comfortable bringing him up to the majors in lieu of a fourth appearance for the Sounds. But what can we expect from him out of this start, and (presumably) those going forward in an A’s uniform?

Last week, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Washington Nationals, which concluded his “Evaluating the Prospects” series. Previously, Baseball America published their top 100 prospects list, as did Baseball Prospectus (top 101), Keith Law, MLB.com and newcomer 2080 Baseball (top 125). Additionally, I put out KATOH’s top-100 list back in January. All of these works attempt to accomplish the very same goal: identifying and ranking baseball’s best prospects. But KATOH goes about it in a very different way than the others. While most others rely heavily on scouting, KATOH relies exclusively on statistical performance.

On the whole, there’s a good deal of agreement between KATOH and the more traditional rankings. Many of KATOH’s favorite prospects have also received praise from real, live human beings who’ve watched them play. JP Crawford, Corey Seager, Orlando Arcia and Julio Urias all fall within this group. However, there are other KATOH favorites who’ve received very little attention from prospect evaluators. The purpose of this article is to give these prospects a little bit of attention.

This hasn’t been a particularly fun season for Twins fans. Not only do they have an abysmal 7-14 record, but their young players — who are supposed to usher in a new era of Twins baseball — haven’t been performing. Top prospect Byron Buxton has been all sorts of terrible, minor-league performer Max Kepler hasn’t been much better, and Miguel Sano has underwhelmed (with the exception of a walk-off single last night) due to an alarmingly high strikeout rate.

Things are about to get a bit more fun for Twins fans, however, as top pitching prospect Jose Berrios is set to debut tonight against the Indians. Based on minor-league performance, the Puerto Rican righty looks like he’s more than ready for the show. He’s been carving up minor-league hitters for a few years now, and has been especially dominant since Minnesota promoted him to Triple-A last July. In 15 starts over that span, he’s struck out 28% of opposing hitters and walked just 6%, resulting in a 2.33 ERA and 2.78 FIP. All that and he’s not even 22 yet. Berrios was a consensus top-30 prospect heading into the year. John Sickels (ninth overall) was the high man on Berrios, while Baseball America (28th overall) was the low man.

Unsurprisingly, KATOH loves it some Berrios. With a projected 10.0 WAR over the next six seasons, he appeared 12th overall on KATOH’s top-100 prospect list. Among pitchers, he ranked second behind teenage uber-prospect Julio Urias. With a ~30% strikeout rate, Berrios has missed plenty of bats in the minors. Since minor -eague strikeout rate tends to be very predictive of big-league success, this bodes well for Berrios’ long-term future.

The Rays called up left-handed pitching prospect Blake Snell from Triple-A to face the Yankees in a spot start on Saturday. Snell looked very good in his debut. Although he lasted just five innings, he yielded just two hits, one walk and zero runs. By fanning six, he maintained the ~30% strikeout rate pace he’d been keeping in the minors for the last year-plus.

Prior to his call up, he owned a 3.01 FIP and 33% strikeout rate in three Triple-A starts this season. Last year, he blew through three minor-league levels — High-A, Double-A and Triple-A — and posted a 1.41 ERA and 2.71 FIP. Snell struck out an eye-popping 31% of opposing hitters, tops among pitchers to record at least 120 minor-league innings last year.

There’s a lot of info out there on a lot of prospects these days. Lead prospect analyst Dan Farnsworth has published detailed organizational lists for all 30 teams that typically run more than 30 deep. Similarly, Baseball America’s 2016 Prospect Handbook profiles the top 30 prospects in each organization.

However, each organization has far more than 30 or 40 players in its minor-league ranks. Using my KATOH projection system, I attempted to find the best of the rest. I’ve identified the players with the most promising statistical profiles who were omitted both from Dan’s organizational list and Baseball America’s organizational top-30 list. These are the players about whom no one is talking.

Yesterday, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Washington Nationals. In this companion piece, I look at that same DC farm system through the lens of my recently refined KATOH projection system. The Nationals have the 16th-best farm system in baseball according to KATOH.

There’s way more to prospect evaluation than just the stats, so if you haven’t already, I highly recommend you read Dan’s piece in addition to this one. KATOH has no idea how hard a pitcher throws, how good a hitter’s bat speed is, or what a player’s makeup is like. So it’s liable to miss big on players whose tools don’t line up with their performances. However, when paired with more scouting-based analyses, KATOH’s objectivity can be useful in identifying talented players who might be overlooked by the industry consensus or highly-touted prospects who might be over-hyped.

Below, I’ve grouped prospects into three groups: those who are forecast for two or more wins through their first six major-league seasons, those who receive a projection between 1.0 and 2.0 WAR though their first six seasons, and then any residual players who received Future Value (FV) grades of 45 or higher from Dan. Note that I generated forecasts only for players who accrued at least 200 plate appearances or batters faced last season. Also note that the projections for players over a relatively small sample are less reliable, especially when those samples came in the low minors.

1. Trea Turner, SS (Profile)

KATOH Projection: 8.8 WAR
Dan’s Grade: 60 FV

Turner scuffled in his first taste of big-league action last year, but previously did a bang-up job in the minors. Speed is Turner’s calling card, but he also showed a decent amount of power when he popped eight homers in the minors. Turner’s high-ish strikeout rates are a bit concerning, but his overall offensive package is extremely promising for a shortstop.

The Nationals have an extremely interesting system, highlighted by a handful of consensus big-upside prospects in Lucas Giolito, Trea Turner, Victor Robles, and Reynaldo Lopez. Though it doesn’t have the name recognition throughout that some of the top-rated teams have, this is one of the more exciting organizations to cover as a prospector (prospectator?). The Auburn and Hagerstown affiliates may end up being the most exciting groups to watch by mid-season.

In general, the Nationals seem to have found a niche bringing in a ton of underrated hit-tool-heavy guys that are hitting their stride at the same time. Expect a lot of turnover with this list by next year, as the top guys are due for full-time gigs in Washington, and the upside prospects start to separate themselves a bit more. If you could criticize any part of the system, there are a few less high-upside arms in the lower minors than many teams like to stockpile. In terms of total value, however, this group doesn’t have a problem stacking up against the rest of the league.

Following the top four are a sizable number of 50+ prospects who provide the big-league club with sufficient low-cost resources to hold them over until their talented crop of players in the lower levels have time to sort themselves out. Though I find myself lower on a few popular prospects like Pedro Severino, Juan Soto and Rafael Bautista, I am equally more enthusiastic than most on less established players like Telmito Agustin, Kelvin Gutierrez and Taylor Hearn.

1. Richard Urena, SS (Profile)

KATOH Projection: 6.2 WAR
Dan’s Grade: 45 FV

Although he played the entire year as a 19-year-old, Urena belted 16 homers as a shortstop in A-ball. His 21% strikeout rate and 3% walk rate speak to his unrefined plate discipline, but Urena’s so good in other areas that KATOH doesn’t much care.
