Wrangling 2021 White Sox Prospects: Prep picks

Over the last few years, the White Sox have moved from avoiding high-end prep talent to giving in to the upside. They’re not bold (or some would say reckless) enough to spend first-round capital on a high school player, but the selection of Jared Kelley marked the third year of using $1 million of their draft pool on teenagers, and the second year of truly aggressive investment.

Size it up year over year, and 2020’s total only lags behind due to the draft’s five-round nature.

  • 2016: $700K
  • 2017: $200K
  • 2018: $1.7M
  • 2019: $5.4M
  • 2020: $3M

The pandemic struck at a particularly damaging time, at least when it comes to those hoping to see some reward from this shift in direction. The winter’s biggest trades involved young talent, but the lack of a 2020 minor-league season prevented the Sox’s recent picks from building their stocks. The hope is that the reward is merely delayed, and not denied.

Either way, the Sox have selected enough promising prep players in recent years to warrant their own post. A few years ago, it probably could be covered in 300 words. Starting with the most recent selection, but not in any particular order after that…

Jared Kelley

The pandemic limited Kelley to 12 innings of high school ball, striking out 34 of the 36 batters he retired, but it’s easier to spin his situation as a positive. For one, had he been able to build up his body of work, he probably wouldn’t have been available for the Sox to draft in the second round, even for an over-slot bonus. Also, he seemed to be able to get the same kind of hands-on, innings-light training that the previous year’s prep selections received, except in Schaumburg instead of Arizona.

He’s not lacking for velocity…

His immediate to-do list sounded kinda like Dylan Cease‘s recent offseasons, where he’s trying to make sure that high-90s heat isn’t wasted with the wrong kind of spin. He’s also trying to find a breaking ball that works for him, as that was the biggest knock on an arsenal that features an advanced changeup for his age.

Matthew Thompson
Andrew Dalquist

The White Sox’s second- and third-round picks in the 2019 draft were dealt a worse hand by the cancellation of the 2020 minor-league season, because this was supposed to be the start of their workload-building. Instead, they had to settle for another year of back-field development.

The reports from prospect rankings reflect progress made in spite of the circumstances. Both are seeing the radar-gun readings rise toward the mid-90s, which is an especially important development for Thompson, whose draft stock took a hit due to worrisome dips. Inconsistency is still there in readings and release point, which Eric Longenhagen took as evidence that they’re still trying to make the tweaks to their delivery and pitch design feel natural. Thompson’s slider seems to rank ahead of Dalquist’s curveball as the best secondary offering.

It’d probably also help to face live, angry hitters in real competitive conditions. Chris Getz made it sound like all three pitchers will be targeted for Kannapolis, or some form of A-ball, for most or all of the 2021 season.

Bryce Bush

In 2019, he ranked in my top 10 with only a little irony. In 2020, he ranked in my top 10 to make a point. He’ll be on the outside looking in this year because he’ll be further removed from brief but legit offensive bursts that were nullified by flaws (swing-and-miss, defense) and bad luck (illness, foul balls off the foot).

Nevertheless, there’s still a lot to like, especially if he’s freed up from trying to handle third base and can make right field his permanent home. The power remains exciting, and while it sucks that he’ll be year behind on refining it, players like him will have plenty of company around baseball.

Cabera Weaver

The lost year is a little more damaging to a guy like speed-based players like Weaver, because that’s a harder tool to hold through the aging process, and he didn’t get a real chance to start compensating with the shoring up of other skills. When we last saw him, he was treading water in Great Falls, hitting .254/.317/.377 at 19. That line reflected improvements in power despite issues against more experienced pitching.

The 2018 sixth-rounder shows up at No. 21 on Baseball America’s list, because they’re encouraged by the increased strength, as well as a shortened swing that should cut down on the swing-and-miss. His speed should keep him in center field for the foreseeable future, and he’ll probably roam the new park in Kannapolis to start the season.

James Beard

Beard has some of the same concerns as Weaver — fast as hell, short on reps — but he’s speedier and one year younger, so he’s got more runway to pull this thing off. He is further away as a hitter than Weaver, as he hit just .213/.270/.307 in his AZL debut with a 39-percent strikeout rate, so he’ll probably open the season in complex ball. Even in a year with a lot of ostensibly challenging assignments, a full-season affiliate feels like a reach.

Lency Delgado

When we last saw Delgado, the 2018 fourth-rounder was surprising us with his ability to play shortstop most of the time in Great Falls, but not so much with his strikeout rate (37.5 percent) and struggles tapping into his strength (.103 ISO). 2021 will be his age-22 season, albeit barely. That’s why Getz said that Delgado is likely to receive a surprising assignment to Kannapolis, even if that kind of pitching feels like a reach for him.

DJ Gladney

The immense power that Gladney showed in his 2019 AZL debut carried over the instructional league, where he hit three homers in his first three games and peaked with an 114 mph exit velocity according to Baseball America. Everything else remains a project, from pitch recognition to footwor to throwing arm. He’s the argument against drafting too many first basemen, because it presents an escape pod for somebody like Gladney with loud tools, even if defense isn’t one of them.

Chase Krogman

His pro debut in 2019 — 4-for-21 with a walk and six strikeouts at Great Falls — doesn’t stand out, but he’s added followers over the course of the 2020 season. He earned First Team honors in the CarShield Collegiate League, the St. Louis-based circuit that Jake Burger briefly played in to get his feet under him.

The White Sox invited him to instructional league, and his work there got him the final spot on Baseball America’s Top 30, saying scouts were “mildly intrigued by his bat speed and potential for lefthanded power because of his strength and knowledge of the strike zone.” The White Sox were intrigued enough to buy him out of a commitment from Missouri State for $190,000, so he’s worth monitoring.

Logan Glass

Like Krogman, Glass received overslot money on Day 3 of the 2019 draft, receiving $175,000 in the 22nd round to thwart a commitment to Oklahoma State. Also like Krogman, he participated in instructs. He’s right-handed and had a bigger strikeout-to-walk disparity in his AZL debut (.284/.342/.403, but two walks to 23 strikeouts over 73 plate appearances), so he may have the later full-season emergence of the two.

PECOTA is here, and well, it’s… dour.


i’m going to choose to interpret this as the Sox are going to be better than the Braves and just roll my eyes at the rest of it.


The Cubs are projected to win more games and they are basically starting a rebuild. Only Reinsdorf


It is kinda amusing that people were complaining about us being too negative on here. Looking at that projection things are probably even worse than we thought. Jerry should have signed Ozuna at the bare minimum.

Im tired of it being labeled negative talk. Its reality we have a fun exciting team at the start of their contention window and ownership completely handicapped this team financially. We are left with a ton of what ifs for the back end of the rotation, dh, rf, backup c, and just overall depth. This team could stay healthy , a lot of guys could project favorably, etc etc and they win 95+ games, but its not hard to see how Pecota may be putting out a much more troublesome projection, some regression from the older players, not as much progress for young players, an injury or two and is 83 wins really that absurd? The question remains you spent multiple seasons tanking, you acquired the young talent, you manipulated their service time, you had them sign team friendly deals, only to sit out on premier free agents. Its inexcusable, and if Jerry, Kenny, or Rick can answer if not NOW when, on “the money will be spent” id love to hear the spin.




As you allude to, PECOTA seems confusingly low even for the pessimistic among us. The projection that stuck out to me as especially odd: according to PECOTA, the White Sox have just as good a chance of winning 62 games (1% outcome) as they do winning 105 games (99% outcome). That seems… very wrong, no?

105 wins is obviously very unlikely, but as unlikely as 62 wins? I mean, heck, they were on a 107 win pace in 2020 before clinching the division. Unless COVID/injuries absolutely ravish this team, 62 wins is almost unimaginable—and probably not even then.

Take Pecota with a grain of salt. They pretty much alway go the conservative route and by default younger teams are less projectable by their standards. That reflects among most of the young teams on this list


Did PECOTA ever admit that the Sox actually won the division in ’05? Pretty sure they said it was still somewhat likely that Cleveland would woin the division even while the Sox were marching through the postseason.

Eagle Bones

Am I reading this correctly in thinking that that second peak on the back half of their win curve says PECOTA has serious questions about their depth and/or overall risk of the roster?

jose robcada

Would be nice to get some higher touted prep position players in the system with most the roster set for a while… dunno how realistic that is this year tho season shortened last year and no even sure if high school baseball will be played this year yet


“2017: $200K”

I will never get over how stupid that draft was, ugh.

Just John

I remember having this thought when Kopech pulled out his best Happy Gilmore during “max-velocity throwing” practices, and now it’s coming to mind again with Jared Kelly.

How important is it to do this?

Boy just watching it makes my arm hurt. In fact, it makes a rather small but conspicuous area on the inside of my elbow hurt.
