The Red Sox made Andrew Benintendi the seventh pick in the draft last summer after he hit a torrid .376/.488/.717 as a sophomore at Arkansas, giving him easily the highest OPS in the SEC. Benintendi wasted no time proving his mettle in pro ball. He kicked things off by slashing .313/.414/.556 between two levels of A-ball, pairing a minuscule strikeout rate with loads of power.

Benintendi’s done more of the same in 2016, only this time at High-A and Double-A. He’s posted equal strikeout and walk rates — both 9% — while also hitting for power and stealing bases. The end result has been an unequivocally excellent .312/.378/.532 batting line. Considering he grades out as an above-average center fielder by Clay Davenport’s numbers, there really isn’t anything Benintendi can’t do.

In case you hadn’t heard, a lot went down yesterday. Here are the prospects who changed teams on deadline day, as evaluated by my newly updated KATOH system. KATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar methodology with consideration also for Baseball America’s rankings.

The Jonathan Lucroy Trade

Lewis Brinson, OF, Milwaukee

KATOH: 7.7 WAR
KATOH+: 9.9 WAR

Brinson posted some terrible numbers in the low minors, but he’s gotten progressively better the past few years, especially in the strikeout department. His 20% strikeout rate from last year was still a bit high, but not alarmingly so. With 31 extra-base hits and 10 steals to his name this year, Brinson has shown a tantalizing power/speed combination.

A bevy of trades went down over the weekend, as this year’s trade deadline-season entered into full swing. Here are the prospects who changed teams the last couple of days, as evaluated by my newly updated KATOH system. KATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar methodology with consideration also for Baseball America’s rankings.

The Andrew Miller Trade

Clint Frazier, OF, New York (AL)

KATOH: 2.7 WAR
KATOH+: 4.7 WAR

Frazier had been promoted to Triple-A a week ago after slashing a strong .276/.356/.469 with 13 steals at Double-A this year. He pairs a high walk rate with decent power and speed, making him one of the most promising offensive prospects in baseball. Despite possessing average speed, Frazier plays mostly the corner-outfield spots these days, and hasn’t graded out particularly well there defensively. This suggests most of his big-league value will come from his hitting. Still, considering he’s a 21-year-old who’s already mastered Double-A, his future looks bright.

Here are the prospects changing hands in today’s deal between Miami and San Diego as evaluated by my newly updated KATOH system. KATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar methodology with consideration also for Baseball America’s rankings.

Josh Naylor, 1B, San Diego (Profile)

KATOH: 4.4 WAR (80th overall)
KATOH+: 4.6 WAR (77th overall)

Though he turned 19 just last month, Naylor’s held his own in Low-A this year. Nothing in Naylor’s batting line is particularly great, but he also lacks a major weakness. He makes a decent amount of contact and draws an acceptable number of walks. His home-run total is a bit underwhelming for a first baseman, but’s made up for it by hitting a bunch of doubles this year. He’s also swiped 10 bases and played good defense, so KATOH gives him something of a pass for his underwhelming offensive numbers.

Adalberto Mejia’s turned in a 2.81 ERA in 18 starts between Double-A and Triple-A this year. His ERA was helped by a low BABIP, especially at the Double-A level. But even so, his 24% strikeout and 6% walk rates signify a solid pitcher. Although he’s pitched professionally since 2011, Mejia didn’t turn 23 until last month, which makes his high-minors dominance all the more impressive. Mejia’s numbers where significantly less impressive in a limited sample last season, but were still encouraging from a 22-year-old at Double-A.

My newly revamped KATOH projection system rates Mejia as a good, but not elite, pitching prospect. It projects him for 3.4 WAR over his first six seasons by the traditional method. Incorporating Baseball America rankings bumps Mejia’s forecast up to 3.9 WAR, which places him 94th overall among all prospects. To help you visualize what KATOH’s projection entails, here is a probability density function showing KATOH+’s projected distribution of outcomes for Mejia’s first six seasons in the major leagues.

To put some faces to Mejia’s statistical profile, let’s go ahead and generate some statistical comps for the southpaw. I calculated a Mahalanobis distance between Mejia’s Double-A and Triple-A performance this year and every season at those levels since 1991 in which a pitcher recorded at least 350 batters faced. In the table below, you’ll find the 10 most similar seasons, ranked from most to least similar. The WAR totals refer to each player’s first six seasons in the major leagues. A lower “Mah Dist” reading indicates a closer comp.

Please note that the Mahalanobis analysis is separate from KATOH. KATOH relies on macro-level trends, rather than comps. The fates of a few statistically similar players shouldn’t be used to draw sweeping conclusions about a prospect’s future. For this reason, I recommend using a player’s KATOH forecast to assess his future potential. The comps give us some interesting names that sometimes feel spot-on, but they’re mostly just there for fun.

A cursory glance at Travis Demeritte’s stat line might lead one to think the he’s an offensive beast. He’s hit a powerful .272/.352/.583 at High-A this year, on the strength of an impressive 25 homers. In addition to his offensive exploits, he’s also swiped 13 bases and played solid defense at second base.

But there’s one bad attribute that largely outweighs all the good stuff: his 33% strikeout rate. Demeritte suffers from chronic contact problems, which have led to problematic strikeout rates ever since the Rangers took him in the first round back in 2013. Though he has the eighth-best wRC+ in High-A this year, he also has the fourth-worst strikeout rate. The latter suggests he’ll have a tough time replicating the former against more advanced pitching.

Raul Mondesi’s calling card has always been his shortstop defense, while his hitting — or lack thereof — left something to be desired. He hit .243/.279/.372 in his age-19 season at Double-A last year, and was similarly underwhelming in the lower levels of the minor leagues. In fairness to Mondesi, he was always exceptionally young for his level. But still: sub-.300 OBPs are never good.

Despite his paltry batting lines, scouts always maintained that Mondesi’s tools suggested some offensive upside. Here in 2016, he’s finally begun to tap into that upside. He slashed an encouraging .259/.331/.448 in Double-A around a 50-game PED suspension, and followed it up with a .304/.328/.536 mark in two weeks at Triple-A. Read the rest of this entry »

The Diamondbacks called upon top pitching prospect Braden Shipley to make yesterday’s start against the Milwaukee Brewers. Though it marked his big-league debut, the 24-year-old has been on the prospect scene for a while now. The Diamondbacks originally drafted him 15th overall out of college back in 2013, and he’s been a fixture on top-100 lists ever since. Last month, Baseball America ranked him 63rd on their midseason list.

Despite his prospect pedigree, Shipley’s minor-league numbers have never quite lived up to his raw stuff. He spent the entirety of the 2015 season at the Double-A level, where he pitched to a 3.50 ERA — though peripherals suggest he wasn’t quite that good. The D-backs bumped him up to Triple-A this year, where he was equally underwhelming.

Before debuting yesterday for Colorado, 22-year-old outfielder David Dahl had recorded a smooth .307/.389/.562 between Double-A and Triple-A this year, including a torrid .456/.508/.886 showing in his short stint at Triple-A. Dahl possesses an exciting combination of power and speed. The former 10th-overall pick belted 18 homers in the minors this year while also swiping 17 bases. Dahl’s 20-plus-homer power is a relatively new addition to his skill set, but it’s not as though he hasn’t shown glimpses of it before.

Dahl has plenty going for him in the power and speed departments, but his strikeout numbers are some cause for concern. He whiffed in 25% of his plate appearances in Double-A last year, and didn’t really improve in that area this season. Much this year’s improvement can be traced back to his sky-high .388 BABIP, while the underlying contact issues linger.

Dwelling on Dahl’s contact rates almost feels like nitpicking, however, especially since his strikeout numbers are trending in the right direction. All in all, Dahl has an awful lot going for him. Whether you look at his stat line or his scouting reports (such as the one published today by Eric Longenhagen), it’s very easy to envision him sticking as a quality everyday center fielder.

My newly revamped KATOH projection system is a big believer in Dahl. My stats-only model rates him as the #12 prospect in baseball, while my KATOH+ model — which also integrates Baseball America’s prospect rankings — placed him at #14. They foresee 9.0 WAR and 11.1 WAR, respectively, over Dahl’s next six seasons.

You’ve undoubtedly heard about the Chapman blockbuster by now. Yesterday, lead prospect analyst Eric Longenhagen gave his take on the prospects involved. Below, I outline what my newly revamped KATOH projection system thinks about the youngsters headed to the Yankees. I also go on to compare that group to the group the Yankees sent to Cincinnati last December in exchange for Chapman’s services.

Note that I’ve included two types of KATOH projection. KATOH denotes the newest iteration of my projection system, outlined yesterday. KATOH+ denotes a version of that same thing which also accounts for Baseball America’s prospect rankings.

Gleyber Torres, SS (Profile)

KATOH Projection: 5.6 WAR
KATOH+ Projection: 7.1 WAR

Although he’s just 19, Torres has been one of the more productive hitters in High-A this year. The Venezuelan shortstop is slashing .275/.359/.433 on the year, with an impressive nine homers and 19 steals. In addition to his offensive exploits, Torres plays an uber-premium position and plays it well.
