This very minute, the author has published an episode of FanGraphs Audio in which lead prospect analyst Eric Longenhagen and that same dumb author play the first inaugural edition of the Over/Under Prospect Game. The rules of the game are discussed in greater detail within the pod episode. In short, though, this is how it’s played:

• Contestant A nominates a rookie-eligible player.
• Contestant A also sets an over/under figure for that player’s WAR in 2017.
• Contestant B chooses the over or under.

For sake of simplicity, we limited the game to 10 nominations total, five by Longenhagen and five by me. The only criterion for a nominee was that he retained his rookie eligibility entering the 2017 campaign.

At long last, the Dodgers found a solution to their hole at second base, acquiring second baseman Logan Forsythe from the Rays on Monday night in exchange for top pitching prospect Jose De Leon. This came after months of rumors around a trade involving De Leon and Brian Dozier. The Dodgers had a surplus of starting pitchers and an opening at second, so it was only a matter of time before they dealt the unproven De Leon.

De Leon’s first crack at the big leagues — a four-start cameo in September — didn’t go quite as well as many had hoped. But he breezed through the minors over the last two years. He broke out in a big way in 2015, striking out an absurd 35% of opposing hitters between High-A and Double-A while walking just 8%. That performance made him a consensus top-30 prospect the following winter.

De Leon battled injuries in the first half of 2016, but began dominating again once he returned to the field. In 16 starts at the Triple-A level, he once again posted a strikeout rate well over 30%, along with solid walk and home-run numbers. De Leon proved himself at the highest level of the minors at the tender age of 23. Pitchers who meet that standard often go on to have success in the majors, especially when they miss bats as prolifically as De Leon did.

De leon grades out exceptionally well by my KATOH system. It projects him for 8.1 WAR over his first six seasons by the traditional method (KATOH) and also 10.1 WAR by the method that integrates Baseball America’s rankings (KATOH+). He’s the 13th-highest-ranking prospect by KATOH+ and the third-highest-ranking pitcher.

Rob Kaminsky got off to a rocky start in 2016. His delivery compromised by a balky back, he put up plenty of clunkers. Over his first 10 outings for Double-A Akron, the Cleveland pitching prospect allowed 30 runs in 45 innings of work. He also spent time on the disabled list. All in all, Kaminsky was a wreck.

Then things turned around. Buoyed by mechanical fine-tuning that accompanied his rehab sessions, the young southpaw was a stud from mid-June onward. In his last 17 starts, Kaminsky allowed two-or-fewer runs 14 times. Over that span, which included the Eastern League playoffs, he hurled 103 frames and saw just 30 runners cross the plate.

Despite his rebound — and having pitched the entire season as a 21-year-old in Double-A — Kaminsky is going in the wrong direction with regard to prospect rankings. He’s plummeted all the way to 26th on Baseball America’s Indians list after coming in at No. 9 a year ago. Our own prospect guru, Eric Longenhagen, has Kaminsky 14th, which is six spots lower than he was 12 months ago.

How did the 5-foot-11 left-hander’s season unfold, and what looms in his future? Here are answers to those questions, courtesy of Kaminsky himself, and Dave Wallace, who was his manager in Akron.

———

Wallace: “If I had to pick one story from this year — pick a specific player — [Kaminsky] would be it. He was absolutely our bulldog down the stretch, and in the second half in general. But in the first half, there were some games that weren’t pretty. He had some significant delivery adjustments that needed to be made. And they weren’t easy.”

Kaminsky: “I would have benched myself, with the first half I had. Everything that could have went wrong, went wrong. I was pitching terrible, and I was pitching hurt. But there were some days I actually felt alright and still got hit around, so it’s not something I can completely blame on the injury. I need to take some ownership of my performance.”

Dan Straily is on his way to becoming a Marlin. According to reports, the Reds have agreed to deal the soft-tossing, veteran righty for a trio of prospects. We’ll have more on the trade in a bit. For the moment, here’s what my KATOH system has to say about the players who are newly employed by the Cincinnati Reds organization. KATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar a methodology with consideration also for Baseball America’s rankings.

Austin Brice, RHP (Profile)

KATOH: 0.9 WAR
KATOH+: 0.9 WAR

After an underwhelming tenure as a starter in the minors, Brice had success in the bullpen last year. Following a move to the pen in June, he posted a 2.10 ERA and 2.90 FIP between Double-A and Triple-A, earning him a September call-up. Brice’s recent minor-league numbers suggest he’ll have a future in the show, even if it’s a short-lived one. KATOH gives him a 50% chance of pitching in the majors again. But as a soon-to-be 25-year-old relief prospect without much track record, he isn’t likely to make a big impact. KATOH considered Brice to be the 10th-best prospect in the Marlins’ system, which says more about the Marlins’ system than it does about Brice.

To put some faces to Brice’s statistical profile, let’s generate some statistical comps for the hard-throwing righty. I calculated a weighted Mahalanobis distance between Brice’s performance this year and every Double- and Triple-A season 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.

The Mariners continued their early-January flurry of activity yesterday, swinging two trades in short succession. First, they dealt left-handed pitchers Thomas Burrows and Luiz Gohara to the Braves for Mallex Smith and intriguing arm Shae Simmons. They promptly flipped Smith, along with prospects Carlos Vargas and Ryan Yarbrough, to the Rays for Drew Smyly.

The most interesting players in this deal are likely the two who’ll make an immediate big-league impact — Smith and Smyly — the former of whom KATOH adored heading into 2016. But the other players changing hands also have their merits. Here’s what my KATOH system has to say about the players who spent most of 2016 playing in the domestic minor leagues.

Note that new Atlanta prospect Burrows is omitted due to a lack of professional experience; new Tampa prospect Vargas, because KATOH doesn’t account for Dominican Summer League numbers, which are the only sort Vargas has produced. KATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar a methodology with consideration also for Baseball America’s rankings.

Luiz Gohara, LHP, Atlanta (Profile)

KATOH: 3.1 WAR
KATOH+: 2.7 WAR

Gohara posted an ERA well above 5.00 over his first three seasons as a pro, but really found his groove last year as a 19-year-old. In 15 starts across two levels of A-ball, he pitched to a dazzling 3.04 FIP on the strength of a 29% strikeout rate. Gohara was one of the more dominant arms in the low minors.

KATOH isn’t completely sold yet, though, as Gohara has a few negative variables in his profile. For one, he was decidedly bad as recently as 2015, which wasn’t terribly long ago. He’s also never pitched above Low-A, meaning he’s largely untested against high-quality hitters and still has a few years of development that have yet to occur. Even his strong 2016 numbers came in a small sample — 79 innings — so KATOH’s a bit skeptical of the track record he does have.

The Phillies have acquired long-time Red Sox starter Clay Buchholz in exchange for minor-league second baseman Josh Tobias. Here’s how Tobias grades out by my KATOH system. (KATOH denotes WAR forecast for the first six years of a player’s major-league career. KATOH+ uses a similar methodology with consideration also for Baseball America’s rankings.)

The Phillies snagged Tobias in the 10th round in 2015, and he’s performed admirably in the minor leagues. He increased his prospect stock by hitting .321/.362/.475 in short-season A-ball to close out his draft year. He had similar success in Low-A last year, but saw his performance crater following a late-season promotion to High-A. He hit a weak .254/.324/.357 at the latter level with a concerning 21% strikeout rate.

Below is an analysis of the prospects in the Kansas City Royals farm system. Scouting reports are compiled with information provided by industry sources as well as from my own observations. The KATOH statistical projections, probable-outcome graphs, and (further down) Mahalanobis comps have been provided by Chris Mitchell. For more information on thes 20-80 scouting scale by which all of my prospect content is governed you can click here. For further explanation of the merits and drawbacks of Future Value, read this. -Eric Longenhagen

The KATOH projection system uses minor-league data and Baseball America prospect rankings to forecast future performance in the major leagues. For each player, KATOH produces a WAR forecast for his first six years in the major leagues. There are drawbacks to scouting the stat line, so take these projections with a grain of salt. Due to their purely objective nature, the projections here can be useful in identifying prospects who might be overlooked or overrated. Due to sample-size concerns, only players with at least 200 minor-league plate appearances or batters faced last season have received projections. -Chris Mitchell

Scouting Report
Strahm saw a 148% uptick in innings as a sophomore at Neosho CC in 2012 and pitched complete games in 11 of his 14 starts (though many of them were not a full nine innings). Strahm dominated and his stuff ticked up as the year went along. (All told, Strahm added almost 15 mph to his fastball between his senior year of high school and his sophomore year of JUCO.) Nevertheless, he lasted until the 21st round of June’s draft. He began experiencing discomfort in his elbow during the 2012 offseason and was misdiagnosed with a stress reaction when in fact he needed Tommy John, which he ultimately received in the summer of 2013. He missed all of 2014 recovering.

This year’s Rule 5 draft came and went yesterday, with 18 players selected in the major-league phase of the draft. All the players selected will need to spend the entire 2017 season on their new team’s active roster (or disabled list). Otherwise, they have to be offered back to their original team.

Here’s how the minor leaguers selected grade out by my KATOH system. KATOH denotes WAR forecast for first six years of player’s major-league career. KATOH+ uses similar a methodology with consideration also for Baseball America’s rankings.

Miguel Diaz, RHP, San Diego (Profile)

KATOH: 0.7 WAR
KATOH+: 0.7 WAR

Scouts love Diaz’s stuff, but it took him five years to get to the Low-A level and he wasn’t particularly dominant there in 2016. He pitched to a 3.71 ERA in 95 innings as a swingman with pedestrian strikeout and walk numbers. Every organization has several players with Diaz’s statistical profile, but the Padres think there’s more to Diaz than his stats.

Sherman Johnson, seen here beginning a terrific double play, wasn’t selected in the Rule 5 draft.

The purpose of this post is to notify the right-thinking members of the public that, contradictory to what “sense” and “reason” would appear to dictate, that Angels infielder and future major-leaguer Sherman Johnson was not selected in baseball’s Rule 5 draft this morning.

Just one day after they dealt away Chris Sale for an impressive crop of young talent, the White Sox continued their tear-down yesterday by flipping Adam Eaton for another nice haul. This time, they landed three young pitchers (roughly in order of consensus future value): Lucas Giolito, Reynaldo Lopez and Dane Dunning.

Lucas Giolito, RHP (Profile)

KATOH: 5.8 WAR (47th overall)
KATOH+: 10.8 WAR (9th overall)

Giolito is one of those cases where the scouting reports outstrip the on-field performance. Scouts have long raved about Giolito’s fastball-curveball combination, and he parlayed it into dominance at the lower rungs of the minor leagues in 2014 and 2015. He was a consensus top-five prospect at this time last year, but things got a little rough for him in 2016.
