The Red Sox acquired a second pitcher on Tuesday following their trade for reliever Tyler Thornburg — in this case, receiving talented left-handed starter Chris Sale from the White Sox in exchange for an impressive return (roughly in order of consensus future value): Yoan Moncada, Michael Kopech, Luis Alexander Basabe and Victor Diaz.

Here’s how the minor leaguers headed to Chicago 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.

Yoan Moncada, 2B (Profile)

KATOH: 6.2 WAR (36th overall)
KATOH+: 14.0 WAR (4th overall)

There’s no denying that Yoan Moncada was one of the most productive hitters in the minors this year. In 61 High-A games, he hit .307/.427/.496. In 44 Double-A games, he slashed .285/.388/.547. He 45 stolen bases across both levels. Moncada excels in multiple areas: he hits for power, runs like crazy, and plays a semi-premium position. His tools are top-notch, which is why he was the consensus No. 1 prospect last summer.

In what will probably be the blockbuster deal of the entire offseason, the White Sox sent LHP Chris Sale to Boston this afternoon in exchange for two of the highest-upside prospects in baseball, Yoan Moncada and Michael Kopech, as well as tools-goof outfielder Luis Alexander Basabe and arm-strength lottery ticket Victor Diaz. Below are my scouting reports on the prospects involved. I’ll update the White Sox prospect list with these reports later this evening. Moncada will be No. 1 and Kopech No. 2, with Basabe slotting in toward the back of the org’s top 10 and Diaz falling toward the bottom of the 40 FV section.

It’s strange that one of the hardest-throwing pitchers in the minor leagues is involved in this deal and yet somehow not its headliner. Such is the prodigious talent of Cuban infielder Yoan Moncada, who I believe to be the best prospect in all of baseball despite his swing-and-miss issues. A generational talent who possesses one of the most robust collections of tools I’ve seen, Moncada has an SEC running back’s body at an athletic and strong 6-foot-2, 205 pounds. There are very few, if any, comparable physiques across baseball.

He’s also a plus-plus runner, both from home to first and on the bases, scattering large swaths of dirt behind him as he traverses the bases. I think Moncada is going to retain that speed for quite a while despite already appearing to have maxed out physically. Even if he does lose a step with age (and it will probably happen at some point), I expect Moncada to retain impact plus speed into his late 20s or early 30s, even if he’s no longer an elite runner at peak.

The Red Sox have landed right-handed reliever Tyler Thornburg in exchange for a trio of players: big-league corner infielder Travis Shaw and prospects Mauricio Dubon and Josh Pennington. Here’s how the minor leaguers headed to Milwaukee 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.

Mauricio Dubon, SS, (Profile)

KATOH: 4.6 WAR (92nd overall)
KATOH+: 3.5 WAR (138th overall)

After hitting respectably in the low levels of the minors, Dubon broke out big time last year. He opened the year by hitting a rock solid .306/.387/.379 at High-A, pairing a 9% strikeout rate with a 12% walk rate. He continued raking following a June promotion to Double-A, but did so a bit differently. His walk and strikeout rates both trended in the wrong direction, but for the first time ever, he hit for power.

The St. Louis Cardinals sent lefty Jaime Garcia to Atlanta in exchange for a trio of minor leaguers this evening. Below are my thoughts on the prospects heading to St. Louis in the deal.

John Gant, RHP (Profile)

The good-bodied and eccentric Gant is probably the likeliest to yield big-league value of the triumvirate acquired by St. Louis tonight. He’s already spent time there, having thrown 50 major-league innings in 2016. As a rookie, Gant struck out nearly a batter per inning (recording a 22% strikeout rate) but also struggled with walks (9.5%). Gant’s fastball sits in the low 90s, mostly 90-93, but will touch as high as 96 and has a slightly above-average spin rate. His changeup is his best secondary offering and best pitch overall. It’s a plus, low-80s cambio that disappears away from lefties as it approaches the plate. Gant maintains his fastball’s arm speed throughout release. There are times when Gant makes a visible effort to create extra movement on the pitch, alters his arm action, and causes his change to flatten out. He also has a loopy, below-average mid-70s curveball. He’s had to use the curve more frequently than a pitch of this quality usually warrants in order to navigate his way through minor-league lineups multiple times.

Here are the prospects changing hands in last night’s deal between Seattle and Atlanta as evaluated by KATOH projection system. KATOH+ represents a player’s WAR projection over his first six years in the majors and includes said player’s Baseball America’s ranking as a variable.

*****

Alex Jackson, RF, Atlanta

Jackson has struggled to make contact ever since the Mariners popped him sixth overall back in 2014. He hit decently in his second crack at Low-A last year, but KATOH is alarmed by his 27% strikeout rate. The fact that he’s a right fielder who neither steals bases nor grades out well defensively also hurts his case. He’s hit for decent power, but the statistical negatives far outweigh the positives. Of course, Jackson was viewed as one of the best prospects in the country a mere two-and-a-half years ago, so it’s likely he still has some potential that isn’t showing up in his on-field performance. The traditional KATOH also projects him for 0.4 WAR.

KATOH+ Projection for first six years: 0.4 WAR

In all-prospect trade Monday night, the Atlanta Braves acquired OF Alex Jackson from Seattle in exchange for pitchers Max Povse and Rob Whalen. Jackson, the sixth-overall pick in the 2014 draft, is the headliner here despite poor performance in pro ball because he was one of this decade’s most decorated high-school hitters.

In 2012, Jackson led all California high-school hitters in home runs with 17. He was a sophomore. Later that summer, Jackson went to Area Codes, where he had one of the event’s most impressive batting practices. His swing length was exposed in games during the event, but Jackson made an adjustment and shortened up the next spring and continued to rake. He hit well against elite prep arms in showcases during his entire high-school career. The track record for hitters who have consistent success at those events is very good.

The deadline for teams to set their 40-man rosters in anticipation of the Rule 5 draft was Friday, November 18th. This means that all Rule 5 eligible players who are not currently on a 40-man roster will be available in the draft on December 8th. Here’s what makes a player Rule 5 eligible, according to MLB.com:

Players who were signed when they were 19 or older and have played in professional baseball for four years are eligible, as are players who were signed at 18 and have played for five years.

For the coming version of the Rule 5 draft, that’s generally any player drafted out of college in 2013 or earlier, drafted out of high school in 2012 or earlier, or signed as an international free agent in 2012 or earlier. That’s just a rule of thumb, but since very few things in life are simple, there are exceptions and loopholes.

Most of the players listed below aren’t good prospects. If they were, their former teams would have protected them — or traded them to a team with an interest in stashing them. The baseball industry has effectively deemed each of these players to be a fringe prospect at best. Who cares about these mostly bad baseball players? Probably a very tiny sliver of the world’s population, if I’m being honest. But if you you’re still reading, I’m willing to bet you’re part of that small minority. And besides, several Rule 5 picks from recent memory have enjoyed immediate big-league success, including Joe Biagini, Matt Bowman and Odubel Herrera.

Below, you’ll find a list of KATOH’s favorite Rule 5-eligible prospects, grouped by position. Due to the aforementioned loopholes, along with the fact that I checked each player’s eligibility manually, it’s possible I omitted a noteworthy player along the way. All players with at least 200 professional plate appearances or batters faced in 2016 were considered. Note that KATOH denotes the relevant player’s WAR projection over his first six major-league seasons, while KATOH+ denotes the same thing while also accounting for the player’s place (or not) among Baseball America’s top-100 rankings.

Below is an analysis of the prospects in the Minnesota Twins 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

Slashed .291/.335/.386 in Florida State League in 2016. Also saved 11 runs at shortstop, per Clay Davenport.

Scouting Report
Gordon was one of this decade’s most heavily scouted high schoolers, leaving evaluators extremely comfortable with his skill set and big-league prospects despite a lack of big tools. Scouts, who were obviously aware of Gordon’s parentage, began seeing a lot of him as a freshman when they were scouting Olympia High School senior outfielder Jesse Winker. Gordon was also a regular at all-star games and showcases throughout his high-school career. After four years, teams saw Gordon as a likely, but unexceptional defensive shortstop who would hit for average and maybe grow into some power as he approached his peak.

The Yankees acquired two high-octane arms from Houston in exchange for veteran catcher Brian McCann today in right-handed pitchers Albert Abreu and Jorge Guzman.

Abreu is the main piece for New York, a somewhat undersized (on paper, anyway) righty with absolutely electric arm speed that he produces with little effort. Abreu’s fastball will sit in the low- to mid-90s, usually 91-96, and touch as high as 98. He has well below-average command of his fastball (and the rest of his repertoire) right now but the ease of Abreu’s delivery allows for considerable projection in this area, though of course it’s not a foregone conclusion that he’ll develop starter-level command.

Every winter, hundreds of nondescript minor leaguers become minor-league free agents. Players are granted minor-league free agency when they’re omitted from a club’s 40-man roster and have also spent at least six years in the minor leagues. In other words, they’re players who weren’t good enough to merit a call-up after several years in the minors, and their organizations suspect they lack the potential to be worthy of a 40-man spot.

Some of these players latch on with new organizations; some of them don’t. But regardless, the overwhelming majority never have much big league success. A couple of years ago, Carson Cistulli found that only about 1% of minor-league free agents produce at least 0.5 WAR the following season. Minor-league free agents are the absolute bottom of the barrel when it comes to player transactions. But there’s an occasional gem at the bottom of that barrel. It’s not unheard of, at all, for a minor-league free agent to make a major-league impact. Here, in no particular order, are some notable examples from the past few years: Gregor Blanco, Jesus Guzman, Donovan Solano, Yangervis Solarte, Jake Smolinski, Jose Quintana and Al Alburquerque. Each left his original organization via minor-league free agency, but achieved some level of big-league success with his new team.

Using my KATOH projection system, I identified the pitchers from this year’s minor-league free-agent class who showed glimmers of promise in the minors. Based on their minor-league numbers, there’s reason to believe they might be able to help at the big-league level sometime soon. This analysis only considers pitchers who faced at least 200 minor-league batters in 2016. For reference, here’s a similar article I wrote last year, and a post from yesterday looking at minor-league free-agent hitters.

*****

1) Jacob Turner, RHP, 2.8 WAR

Turner was the ninth-overall pick back in 2009, and broke in with the Tigers as a 20-year-old in 2011. Six years and three new organizations later, his career is at a crossroads. Turner hasn’t had much success getting big-league hitters out, as evidenced by his 323 big-league innings of 5.00 ERA ball. It’s been a struggle for Turner, but he’s still just 25 and is coming off of a solid showing in Triple-A last year. Despite an unsightly ERA, the 6-foot-4 righty posted a 3.69 FIP at the highest level of the minors with the White Sox. The book isn’t closed on his career yet.
