The Rangers lost both Drew Stubbs and Shin-Soo Choo to injury over the weekend, leaving them relatively bare in the outfield. To fill the void, they’ve called up top prospect Joey Gallo, who’s perhaps one of the most exciting prospect in baseball due to his exceptional power. We’ve been here before. The Rangers called Gallo up last summer, too, but thanks to a .204/.301/.417 performance in the show, they wisely concluded he needed more seasoning in the minors. Most concerning of all was his 46% strikeout rate, which was literally over twice the league average.

Based on his recent performance, it seems Gallo’s gotten the seasoning he needed. Last year, Gallo hit .240/.342/.520 between Double-A and Triple-A, and struck out in a super-concerning 37% of his trips to the plate. This year, he’s slashed his strikeout rate to a merely mildly-concerning 23% in Triple-A. As a result, he’s hit a gaudy .265/.415/.639.

Two months ago, the Houston Astros looked like the obvious favorites in the AL West, but things haven’t exactly gone according to plan. Houston’s off to a disappointing 15-24 start, due in part to some terrible performances in the outfield. While George Springer and Colby Rasmus have hit well, Carlos Gomez, Preston Tucker and Jake Marisnick have a combined 252 plate appearances this year, and each has recorded a wOBA below .250. Gomez has been one of the biggest disappointments in baseball this year, and his struggles appear to be more than just bad luck.

To help fortify their struggling outfield, and provide a spark to their under-achieving team, the Astros have called up 24-year-old Tony Kemp from Triple-A. Although he stands at just 5-foot-7, Kemp hit .314/.393/.391 with 38 steals last season between Double-A and Triple-A, and was off to a similarly good start this year, slashing .298/.410/.405 at Fresno. Kemp’s a second baseman by trade, but has played a good deal of center and left field of late. Dan Farnsworth ranked Kemp 11th on his Astros prospect list heading into the year. Kemp appeared 15th among Houston prospects on Baseball America’s list. KATOH, however, is won over by his stellar minor-league track record. My system ranked him #2 in the Astros system and #53 overall.

With Starling Marte away on paternity leave, the Pittsburgh Pirates have called up prospect Alen Hanson from the minor leagues. Hanson was off to a fine start in Triple-A, slashing .288/.309/.398 with seven steals. He spent all of last season at the Triple-A level, too, and hit similarly well: .263/.313/.387 with 35 steals. Throw in that he’s primarily a middle infielder, and it’s clear Hanson had little left to prove in the minors.

If it feels like Hanson’s been on the prospect radar for ages, it’s because he has. Originally signed out of the Dominican way back in 2009, he began gracing top-100 lists after a .309/.381/.528 showing in Low-A back in 2012. Despite his lengthy minor-league tenure, Hanson still has youth on his side. He’ll will play the entire 2016 season as a 23-year-old. Read the rest of this entry »

The Yankees have called up 23-year-old Dominican-born catching prospect Gary Sanchez from the minor leagues. Sanchez was off to an excellent start in Triple-A this year, slashing .288/.336/.541 in 27 games. Heading into the year, he ranked 21st on KATOH’s top 100 list, second to only Chance Sisco among catchers. Sanchez’s 2016-to-date performance has only served to improve his prospect stock. He figures to serve as New York’s designated hitter for the time being with Alex Rodriguez on the shelf. Read the rest of this entry »

Due to a fractured thumb, the Royals will be without Mike Moustakas for at least the next few weeks. No doubt, Kansas City will miss their three-plus win, All-Star third baseman. But as is often the case in baseball, one man’s misfortune is another’s opportunity. In this instance, the beneficiary is Cheslor Cuthbert, whom the Royals recalled from the minors to replace Moustakas.

Unless you’re a Royals fan or a prospect connoisseur, you might have no idea who Cheslor Cuthbert is, but my nerdily-sorted spreadsheets really like the Nicaraguan infielder. Last year, he hit .277/.339/.429 as a 22-year-old in Triple-A. He also struck out in an encouragingly low 14% of his trips to the plate. He already looks like a Royal.

That performance, along with the fact that he plays primarily third base — a somewhat premium defensive position — landed Cuthbert at 74th on KATOH’s preseason top-100 list, placing him tops among Royals farmhands. That was before he opened this season by slashing .333/.402/.624 in 24 games. He was one of the very best hitters at Triple-A over the season’s first month, and was quite possibly the best prospect-age hitter in Triple-A.

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.
