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.

A mere 13 months ago, the Houston Astros selected Alex Bregman with the second pick in the amateur draft. Tonight, he’ll suit up for the Astros, after he gave Houston no choice but to call him up to the show. The 22-year-old hit .311/.412/.589 in the minors this year, including a .356/.387/.685 showing during his 17-game pit stop at Triple-A. Last season, his junior one at LSU, Bergman slashed .323/.412/.535 and, unsurprisingly, had little issue adapting to life in the pros. He closed out his draft year by hitting a strong .290/.358/.408 across two levels of A-ball.

Bregman pairs exceptional contact ability with ample power and a good walk rate, making him an all-around offensive threat. Bregman owns a minuscule 10% strikeout rate as a professional, yet has still managed a .200 ISO. Very few hitters possess Bregman’s combination of contact and power.

As if that weren’t enough, Bregman also provides value through means other than his hitting. The Astros have given him time at several positions this year in anticipation of his promotion, but he’s a shortstop by trade. That suggests he could be a fine defender at just about any place further down the defensive spectrum. He’s also swiped 20 bases in his year as a professional player, indicating good (or, at least, usable) speed.

As you probably imagined, my newly re-vamped KATOH system is head-over-heels for Bregman. He’s easily the top prospect in the land according to my math. Both KATOH (which considers stats only) and KATOH+ (which also incorporates prospect ranks) peg him for more than 17 WAR over his first six years in the big leagues.

Back in January, I made some tweaks to my KATOH projection system, and have been using that updated model for the past several months. That model was unquestionably better than the previous versions, but it left me unsatisfied. While it addressed many of the flaws from previous iterations, there was still a lot of information it wasn’t taking into account.

I’ve been plugging away behind the scenes, and finally have a new version KATOH to share with the world. In what follows, you’ll find some detail on the new model, including its notable updates. I’ll be using this model in all of my prospect analysis from this point forward. Below, you’ll find a quick run-through of the notable tweaks, followed by an updated top-100 list.

Choosing projection window based on level, rather than age

In my previous model, I projected out based on a player’s age. If a player were 22, I projected him through age 28; If he were 24, I projected through age 30. This resulted in KATOH undervaluing players who were old for their level. The goal of KATOH is to predict the value a player will generate during his six-plus years of team control. By projecting a 22-year-old through age 28, KATOH failed to capture some of that value in cases where the 22-year-old was still in A-ball.

This time around, I chose my windows based on level, rather than age. I projected the next six seasons for players in Triple-A. I did the next seven for players in Double-A, eight for A-ballers, and nine for Rookie ballers.

We all knew Dan Vogelbach’s days in the Cubs’ organization were numbered. His lackluster range limit to first base, and if we’re being serious, even that’s a stretch. He didn’t have a future with the Cubs. Not only do they lack a DH, but they also have more quality hitters than they have lineup spots. A trade was imminent, and the Cubs finally pulled the trigger on Wednesday night, dealing the 23-year-old slugger for unheralded — yet effective — reliever Mike Montgomery and Double-A hurler Paul Blackburn. Triple-A pitcher Jordan Pries also heads to Chicago in the deal.

KATOH Forecast for first six seasons: 2.8 WAR

Vogelbach offers zero defensive value, which means he’ll need to hit a lot to get by in the big leagues. To his credit, however, his exploits in the minors this year suggest he might hit enough to make for a productive DH. He’s slashed a gaudy .318/.425/.548 in Triple-A, and has little left to prove in the minor leagues. KATOH isn’t crazy about Vogelbach on account of his defensive limitations, lack of speed and iffy contact numbers. Vogelbach’s power is excellent, but the other facets of his game threaten to chip away at his value.

Less than a month ago, the Washington Nationals called up top prospect Lucas Giolito, with the hopes that he’d fill a hole in their rotation. However, as often happens with promising young pitchers, Giolito looked a bit overmatched in his first taste of the big leagues. He recorded more walks than strikeouts in his two starts with Washington, and was subsequently sent back to the minors to further refine his breaking stuff. Giolito will surely be back sooner rather than later, and still appears to have a bright future ahead of him. For now, though, the Nationals are turning to another electric young arm: hard-throwing 22-year-old Reynaldo Lopez debuts tonight against the Dodgers.

Lopez was signed out of the Dominican back in 2012, and his stuff has landed him on top-100 prospect lists for a couple of years now. But up until this season, he his minor-league performance hadn’t quite matched up with his stuff for any extended period. He spent the 2015 season in the High-A Carolina League, where he posted a mediocre 4.09 ERA. His peripherals suggest he pitched much better than that, but his 23% strikeout rate still underwhelmed.

He opened 2016 at the Double-A level, and soon began missing bats at a rate commensurate with his stuff. His 30% strikeout rate is tops among qualified Double-A pitchers this year. He also managed to keep his walk rate under 8%. Though he wasn’t super sharp in his two most recent starts at the Triple-A level, the body of Lopez’s 2016 campaign bodes well for his future in the bigs.

Almost right after after treating us to Tyler Glasnow day, the Pirates are giving us another promising debutante to fuss over. First base prospect Josh Bell will debut for Pittsburgh in tonight’s game against the Cubs. Bell crushed Triple-A pitching this year to the tune of .324/.407/.535.

Bell posted a healthy .212 ISO in Triple-A this year, but in years past, he’s hit for an underwhelming amount of power — especially for a 6-foot-4 first baseman. Between 2014 and 2015 combined, he managed just 16 homers, and didn’t exactly compensate with loads of doubles and triples. Instead, he made lots of contact, which resulted in loads of singles.

Less than a month ago, the Pirates called up top prospect Jameson Taillon from the minor leagues, and slotted him into their struggling rotation. With Taillon now sidelined by shoulder fatigue, the Pirates have once again dipped into their minor-league repository. Today, they’ve called up yet another top-tier pitching prospect in Tyler Glasnow. Glasnow’s spent the past three months putting up sick-nasty numbers with the Pirates’ Triple-A affiliate. In 96 innings across 17 starts, he boasts a 1.78 ERA and 2.94 FIP. He’s struck out a remarkable 30% of batters faced this year, which is tops among qualified Triple-A hurlers. Triple-A hitters proved to be no match for his filthy fastball-curveball combination.

Glasnow’s mowed down minor-league hitters, but many are concerned that his lackluster command will prevent him from succeeding at the next level. That’s a big reason why the Pirates kept him in the minors as long as they did, and why they passed him over for Taillon when they needed a pitcher last month. As lead prospect analyst Eric Longenhagen noted in a recent chat, “His stuff is hellacious and pitchers with that body type often develop command late, but there’s a non-zero chance Glasnow never throws enough strikes to dominate.”
