ZiPS 2021 Top 100 Prospects

For the sixth year, ZiPS returns to crank out its top 100 prospects for the upcoming season. If you’re unaware of what the ZiPS projections are or the purpose they serve, please consult this article as well as this one while I reconsider my public relations strategy.

I like to think that I’ve developed a pretty useful tool over the years, but don’t get me wrong: a projection system is not even remotely a substitute for proper scouting. While ZiPS and other systems like it can see patterns in the data that are hard for humans to extract, humans have their own special tricks. Projecting prospects is hard, as you’re mostly dealing with very young players, some of whom aren’t even done physically developing. They play baseball against inconsistent competition and have much shorter resumés than established major leaguers.

That last bit is an especially tricky puzzle for 2021. Thanks to the COVID-19 pandemic, we didn’t have a minor league season. Some prospects were left to train at home, while others saw time at their team’s alternate site or in Fall Instructional League. But those environments can’t replace live opponents who are trying to crush your hopes and dreams, and they didn’t generate much in the way of useful statistics.

You will also notice, as usual, that there are a few players who appeared on Eric Longenhagen’s Top 100 who are missing here, simply because they have only played in high school and no professional games. It’s not that ZiPS dislikes them or doubts their future, it’s just that the system doesn’t have anything useful to say. ZiPS has the capability to use college stats when it has little choice — which is why you’ll see Spencer Torkelson and Austin Martin appear — but there’s just nothing for ZiPS to work with when we’re talking about someone like Jasson Dominguez.

But when ZiPS does have something to say, it does a decent job of identifying future major leaguers. If we look back to the prospects from the inaugural ZiPS Top 100, they’ve gone on to combine for 638 WAR in the majors. And while ZiPS will miss more often on the toolsy guys, there were also some higher floor guys who ZiPS liked better than the other prognosticators, including Mookie Betts, George Springer, Marcus Semien, Kolten Wong, and Joc Pederson. This is less of a problem in the big leagues because by the time a player has reached the top of the organizational ladder, they will generally have already needed to convert at least some of their raw tools into baseball skills. Statcast and the like give us clever ways to capture things like speed or a pitcher’s stuff more effectively than ever before, but these measures can’t tell us everything, and they’re generally less available for minor leaguers. ZiPS doesn’t know who has a hitch in their swing and an inconsistent arm slot. As it turns out, however, actual performance has a lot of predictive value, and ZiPS is very happy to see a two-to-three win contributor like Wong where a prospect-watcher may be relatively unimpressed with his upside potential. One good example in the other direction is Dellin Betances. When he was an extremely erratic starting pitcher with severe control issues, ZiPS didn’t see any real upside. After all, guys who walk seven batters a game in the minors rarely pan out in the majors. What ZiPS couldn’t see was one of Betances’ teammates teaching him a new slider grip, which resulted in a pitch on the slider/cutter border that terrorized batters for five seasons.

Now to consider this year’s exercise. There’s not as much movement here as there has been in past years simply because there was no minor league season to send stocks soaring or crashing. Players with more upside but who needed time to develop it generally lost the most in the projections as a result of losing a year of their careers, as did the older prospects. One other difference of note is that I spent much of 2020 honing the minor league translations for lower-level prospects, with the biggest change being the implementation of some probability-based fielding data into the BABIP models. Re-projecting the 2014 prospects using this refined model would have improved the WAR total for the new ZiPS 2014 top 100 to 663 WAR. I do expect ZiPS to cede some ground to the scouts as time goes on; the higher floor, lower ceiling prospects that ZiPS likes tend to reach the majors more quickly.

With less dramatic changes and no minor league season to talk about, most of the commentary below will concern players who got major league time in 2020, as they played actual games. Without further ado, the 2021 ZiPS Top 100!

Wander Franco remains at the very top of the list. He’s as complete a talent as you can find at his age and the missed year probably has a bigger cost to his wallet than to his development. There’s literally as much difference between Franco and runner-up Ha-seong Kim’s projections as there is between Kim and number 30 prospect Alex Kirilloff. ZiPS projects 46 career WAR for Franco and sees him as an .875 OPS hitter at his peak, an absolutely bananas projections for a player who has yet to play above the High-A Florida State League. If ZiPS gave number grades, he’d be an 80, probably joining Mike Trout. Trout was “only” projected at 4 WAR as a rookie, but that was still an optimistic projection until we saw what he actually did!

You get the biggest difference between my list and Eric’s early with the aforementioned Kim. Kim projects as a three-win hitter right now, and the best player coming over from Korea ever projected, so given the lack of speculation required to make him a significant talent in the majors, he was always going to have a very high ranking.

ZiPS has been high on Ke’Bryan Hayes for a very long time and over his minor league career, it had him as the best defensive third baseman since Matt Chapman. Sometimes glove guys in the minors don’t actually work out that way — he can ask his teammate Gregory Polanco — but Hayes gave very little reason to doubt the hype in his limited time in the majors in 2020. He’s quite obviously not going to continue to hit .376/.442/.682, but that performance was enough to shift his projection in a positive direction. In terms of rest-of-career WAR, ZiPS has Hayes as fourth in baseball among third basemen, behind only Alex Bregman, Chapman, and José Ramírez, and just edging out Alec Bohm and Rafael Devers.

Ian Anderson and Sixto Sánchez excelling late in the season was enough to boost their ranks significantly. Deivi García also got a jump, and while his stats weren’t obviously a plus, ZiPS isn’t worried about the extra homers he allowed. ZiPS also thinks that Nate Pearson’s walks were a little higher than you’d expect from his plate discipline stats, and getting some actual velocity and contact data in there also gave him a bump.

The two biggest beneficiaries of the revised low minors translations are Julio Rodríguez and Braden Shewmake, though for different reasons. The boost to Shewmake’s BABIP and the inclusion of wider college data make the projections more confident that he has a very respectable floor. Rodríguez has more downside, but also more upside scenarios that involve him becoming a 30-homer hitter in a corner, with a chance at his plate discipline improving. On-average, ZiPS sees Rodríguez like Jermaine Dye, which isn’t bad for a mean expectation.

Seasons lost due to injuries hit the rankings of both Brendan McKay and Brent Honeywell Jr. significantly. But the Rays got good news elsewhere: Josh Fleming looks like he’s going to stick as a mid-rotation starter with no star potential and Luis Patiño’s minor league translations took a significant jump up. And, of course, there’s Randy Arozarena, who still qualifies for the Rookie of the Year award in 2021, as weird as that feels after his postseason performance. Some may be disappointed by Arozarena only ranking 12th, but he’s not likely to have a ton of defensive value and there’s probably not another breakout waiting. In all, the Rays have 11 players in the ZiPS Top 100.

As an Orioles fan, it pained me to see Adley Rutschman slip to eighth. What it comes down to is that he’s not an 18-year-old phenom and catcher prospects have very high failure potential, so ZiPS sees him having missed a year of development as a significant problem.

One projection certain to disappoint is that of Andrew Vaughn, a player who the White Sox are making noise about promoting aggressively this year. I can’t say for certain if that desire is earnest and not partially a public cover for not going after someone like Nelson Cruz for the team’s DH spot, but ZiPS is not sold at all on Vaughn. ZiPS is aware of his power while at Cal. Indeed, if all it knew was Vaughn’s sub-.450 slugging debut while not being young for A-ball, he would not have come anywhere near this list. On the flip side, college was enough for Spencer Torkelson and Austing Martin to do well. If Torkelson had received an official ZiPS for 2021, his top comp would be Jim Thome. That’s obviously not the average result. The projections see Martin as a high-average, high-OBP hitter in his prime, with a peak in the 115-125 wRC+ range, certainly enough that he doesn’t necessarily have to excel at an up-the-middle defensive position.

Overall, there was a lot of agreement between ZiPS and The Board. In all, 74 players appeared on both top 100 lists, which is about average for ZiPS/scout consensus; there tended to be a similar amount of overlap between ZiPS and Keith Law’s rankings when both of our lists were housed at ESPN.

Does ZiPS incorporate postseason performance? I.e., does it “know” what Randy Arozarena did last October?
