Baseball is flush with randomness. Time and time again, we trick ourselves into believing we have a good sense of what’s going to happen next, armed with an ever-growing arsenal of measurements, metrics, and projections. Yet, without fail, baseball constantly finds a way to catch us by surprise. One of those surprises has taken St. Louis by storm the last couple of weeks. First baseman Luke Voit debuted for the Cardinals on June 25th and has proceeded to hit .333/.379/.704 between then and now. He’s currently sporting a 179 wRC+, which as the title suggests, is one of the best in baseball among batters with at least 29 plate appearances.

Of course, 29 plate appearances is too few to tell us much of anything about what Voit will do going forward. Luckily, Voit has a lengthy minor-league track record that can. And now that you’ve fallen for the clickbaity title, you’re stuck reading about it.

While surprising, Voit’s performance didn’t come completely out of nowhere. He was a good hitter in the minors, amassing over 30 homers since the start of 2015. He slashed .322/.406/.561 at Triple-A this year and .297/.372/,477 in 2016 at Double-A. Voit also managed to keep his strikeout rate comfortably below 20%, which allowed him to hit for both average and power.

After their roster was ravaged by injuries, the Yankees promoted a trio of promising hitting prospects last week in Tyler Wade, Miguel Andujar and Dustin Fowler. Fowler, the most promising of the three, was supposed play regularly in New York’s outfield. Unfortunately, his big-league career was derailed as soon as it started in horrific fashion.

Following Miguel Montero’s kerfluffle with Jake Arrieta, the Cubs designated Montero for assignment today. In his place, they called up Victor Caratini from Triple-A. The switch-hitting Caratini had been tearing up PCL pitching this season to the tune of .343/.384/.539. Needless to say, that’s mighty exciting coming from a catcher. Caratini’s offensive profile is built around an encouraging combination of contact and power. At Triple-A this season, he struck out in less than 15% of his plate appearances while posting an ISO just south of .200. The latter was largely due to his 20 doubles. Caratini has also run high walk rates in the past.

KATOH likes Caratini more than most, projecting him for 5.1 WAR over his first six seasons by stats-only KATOH and 3.7 WAR by KATOH+, which incorporates his prospect ranking. Those marks place him 80th and 100th, respectively, among prospects. Caratini doesn’t even sniff most scouting-based top-100 lists.

To put some faces to Caratini’s statistical profile, let’s generate some statistical comps. I calculated a Mahalanobis distance between Caratini’s Triple-A performance and every season since 1991. 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.

Yankees second baseman Starlin Castro has landed on the DL after straining his hamstring last night. In a parallel universe, a parallel me is writing this article about Gleyber Torres, whom KATOH+ regarded as the No. 2 prospect in baseball behind Vlad Guerrero Jr. But since Torres’ season recently came to an end, the call-up goes to Tyler Wade, who is an interesting prospect in his own right.

A fifth-round pick out of high school in 2013, Wade put himself on the prospect map when he slashed .280/.343/.353 as a 20-year-old shortstop in High-A. He built upon that with a solid campaign in 2016 and hit an excellent .313/.390/.445 this year. He’s been especially hot of late, slashing .366/.455/.505 with 11 steals over his last 25 games. Wade hasn’t hit for a ton of power in the minors — his career ISO is just .085, though it ticked up to .132 this year — but he does just about everything else offensively, including making contact, drawing walks and stealing bases.

Wade has played shortstop, second base, third base and all three outfield spots this year. However, most of his reps have come at short. He hasn’t graded out well at the position by Clay Davenport’s numbers, but given how the defensive spectrum works, it stands to reason that he’d be fine at second base. The fact that he’s remained at shortstop all the way through Triple-A is telling.

There’s a youth movement taking place in Oakland. The A’s jettisoned both Trevor Plouffe and Stephen Vogt in the last couple of weeks, replacing them with Matt Chapman and Bruce Maxwell. Another big splash came this weekend, when Oakland summoned prospect Franklin Barreto to play second base.

Barreto continued to hit for an encouraging amount of power as a minor leaguer this year, especially considering he played in a park that massively suppresses homers (by PCL standards). However, his strikeout rate spiked from 18% to 30% as he transitioned from Double-A and Triple-A and his stolen-base numbers plummeted. As a result, his KATOH forecast has taken a hit. I have him projected for 4.8 WAR over his first six seasons by stats-only KATOH and 5.4 WAR by KATOH+, which incorporates his prospect ranking. Those marks place him 90th and 55th, respectively, among prospects, down from 18th and 20th in the preseason.

Daily notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

Breiling Eusebio, LHP, Colorado (Profile)
Level: Short Season  Age: 20   Org Rank: NR   Top 100: NR
Line: 5 IP, 4 H, 0 BB, 1 R, 7 K

Notes
It’s been a strong 2017 affiliate debut for Eusebio, who looked quite good throughout extended spring training, his fastball often sitting 90-94 with some tail. His low-70s curveball improved as we inched closer to the summer and it, too, was missing bats as June arrived and is currently average, flashing above. Eusebio has trouble timing his delivery, which can negatively impact his command, but he’s deceptive, throws hard for a lefty starting-pitching prospect, and has breaking-ball feel. Very much a prospect.

With Josh Reddick sidelined by a concussion, the Astros summoned 23-year-old center fielder Derek Fisher to the big leagues yesterday. The early returns are good: in his debut, Fisher went 2-for-3 with a homer and two walks.

Fisher had more than earned this opportunity, slashing .335/.401/.608 at Triple-A this year. A power-speed threat, Fisher eclipsed 20 homers and 20 steals in both 2015 and 2016, and Eric Longenhagen gave him raw power and speed grades of 60 and 70, respectively. Fisher had a bit of a strikeout problem in the past, but has managed to slice his strikeout rate from 27% last year to 19% this year without sacrificing any of his power.

KATOH loves Fisher, which shouldn’t come as much of a surprise given his excellent performance this year. I have him projected for 8.1 WAR over his first six seasons by stats-only KATOH and 6.3 WAR by KATOH+, which incorporates Eric Longenhagen’s relatively modest 45 FV grade. Those projections make him the 18th- and 48th-best prospect in baseball, respectively.

To put some faces to Fisher’s statistical profile, let’s generate some statistical comps for the toolsy center fielder. I calculated a Mahalanobis distance between Fisher’s Double-A and Triple-A performance and every season since 1991. 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.

It’s not immediately clear how, or how often, Houston will work Fisher into their lineup once Reddick is healthy. But Houston would perhaps benefit from shifting some of Nori Aoki’s at-bats to Fisher, giving them an outfield of Fisher, Reddick and George Springer. Regardless, Fisher’s rare combination of power, speed, and contact ability makes his future look incredibly bright. And he made it clear with his 2017 performance that he has nothing left to prove in the minor leagues.

In addition to calling up stud center-field prospect Lewis Brinson, Milwaukee also recently summoned talented lefty and KATOH crush Josh Hader. Although Hader’s worked primarily as starter in the minors, the Brewers plan to use him out of the bullpen for the time being. A 19th-round pick out of high school, Hader’s been exceeding expectations for years. He owns a 3.87 FIP and 27% strikeout rate in 541 minor-league innings. In 25 starts between Double-A and Triple-A last year, he pitched to a sparkling 3.07 FIP with a 31% strikeout rate.

Things didn’t go as swimmingly for Hader in Triple-A this year, however. He maintained a solid 22% strikeout rate, but matched it with a 14% walk rate and coughed up an uncharacteristic 14 homers in 52 innings. The end result was a 5.37 ERA and 4.93 xFIP, which doesn’t exactly scream “big-league ready.”

Still, KATOH remains optimistic. My system projects Hader for 5.0 WAR over his first six seasons by the traditional method and 5.7 WAR by KATOH+, which incorporates scouting rankings. That makes him one of the top 10 pitching prospects in the minors, and a mid-top-100 guy overall.

To put some faces to Hader’s statistical profile, let’s generate some statistical comps for the 6-foot-3 lefty. I calculated a weighted Mahalanobis distance between Hader’s Double-A and Triple-A performance and every season since 1991. 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.

Despite his relative lack of prospect pedigree, Hader’s stuff is almost certainly of big-league quality. The lefty’s fastball averaged over 94 mph in his debut, and both his slider and changeup project to plus according to Eric Longenhagen. However, scouts have long contended that Hader profiles best as a reliever. To wit:

• Eric Longenhagen, 2017: “Those who consider him a reliever cite the rarity of a delivery like this in starting rotations across baseball, the potential platoon issues Hader might face as a low-slot lefty, and his fringey control.”
• Baseball America Prospect Handbook, 2016: “His reliance on his outstanding fastball combined with just ordinary control make him a possible bullpen candidate.”
• Baseball America Prospect Handbook, 2015: “Durability will always be a question because of Hader’s size and how he slings the ball across his body… His reliance on his fastball profiles him better as a reliever.”
• Baseball America Prospect Handbook, 2014: “It’s one of the most unconventional deliveries a starter could use… Scouts see him as a future lefty reliever where his low arm angle will make life difficult for lefthanders.”

Despite the persistent “future reliever” label, Hader dominated for years as a starter in the minors. But when he finally sputtered in Triple-A, the Brewers seemingly decided to try him in the pen. Given his stuff and minor-league performance, I have little doubt that he’ll be a dominant force there.
