Brandon Walter hasn’t come out of nowhere, but he has come a long way. A 26th-round pick in 2019 out of the University of Delaware, the 25-year-old southpaw went into last season a veritable unknown, and he left it as the fastest riser in the Red Sox system. Displaying elite movement from a low arm slot, Walter fanned 132 batters and allowed just 67 hits in 89.1 innings, between Low-A Salem and High-A Greenville. He’ll enter the 2022 campaign ranked No. 10 on our newly-released Red Sox Top Prospects list.

Walter discussed his repertoire, and his unexpected emergence in a steadily-improving system, last month.

David Laurila: Your Baseball America writeup said, among other things, “His stuff and pitch data suggest reason to believe in a big ceiling.” What does that mean to you, particularly the reference to data?

Brandon Walter: “I’ve learned a lot over the last couple of years, especially since Chaim Bloom came into our organization. They’re big on analytics and pitch data [and] they’re preaching it to us. To me, it mostly means that my stuff is plus, so I can simplify and just throw it in the zone. I can make hitters deal with what I’m throwing instead of trying to hit corners and risk falling behind in the count. Basically, I can just try to get ahead with with my three pitches and compete that way. Getting that information and knowing that my stuff is above average allows me to just attack hitters.”

Laurila: Has the data reinforced things you kind of already knew, or has any of it actually come as a surprise? Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the Boston Red Sox. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the second year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the numbered prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here. Read the rest of this entry »

Matt Wallner has taken a circuitous route in his quest to play close to home. Geographically speaking, it might be better-described as an oblong route. The 24-year-old Minnesota Twins outfield prospect grew up thirty minutes northeast of Target Field, then circumstances sent him to Hattiesburg, 17 hours south. Since being drafted 39th overall in 2019 out of the University of Southern Mississippi, Wallner has played in Elizabethton, Tennessee and Cedar Rapids, Iowa, the latter of which sits four-and-a-half hours southeast of where he started.

Exposure-wise, the shape of Wallner’s boomerang journey changed when his intended destination out of high school dropped baseball. The left-handed-hitting slugger — No. 10 on our newly-released Twins Top Prospects list — had planned to continue his studies in Grand Forks, North Dakota, four-and-a-half hours northwest of the Twin Cities.

“[The University of] North Dakota cut baseball in April of my senior year,” explained Wallner, who battled back from a hamate injury this year to log a 131 wRC+ and wallop 15 home runs in 294 plate appearances at High-A Cedar Rapids. “I had some connections to Southern Miss through the North Dakota coach, so I went for a visit and fell in love with it. Playing college baseball when it is warmer than 30 degrees was enticing.”

Belying the fact that he considers his freshman fall at the Conference USA school “the biggest jump I’ve ever had to experience,” Wallner went on swing a hot bat in his first taste of high-profile collegiate competition, compiling numbers that included 19 dingers and a 1.118 OPS. He went on to set Southern Mississippi’s career home run record, going deep 58 times in three seasons. Read the rest of this entry »

Every week, we will recap amateur baseball happenings in a post like this, with a focus on how the action impacts the next three draft classes, especially this year’s. You’ll find a primer on our approach, as well as our observations from Week 1, here. Now on to this past weekend’s notes.

Ben Joyce, RHP, Tennessee Volunteers: 0.2 IP, 1 H, 1 BB, 1 K (Current Rank: College Pitcher of Note, 35+ FV)

That line next to Joyce’s name actually represents the composite of his Saturday and Sunday showings, as he faced just four batters combined. Joyce has become a Twitter darling by frequently getting into the triple-digits with a fastball that has touched an eye-popping 103 mph, but after missing the 2021 season due to Tommy John surgery, and with just three innings in the books so far this year, scouts are still very much in the to-be-determined phase of figuring out where to line him up on draft boards. While we haven’t seen this kind of velocity since early-career Aroldis Chapman, teams are still trying to determine what else Joyce can do. So far, he’s been hovering around 90% fastball usage while generally finding the zone with the pitch; maybe we’d all lean that heavily on our heater if we could throw it as hard as Joyce does. Still, while his low-to-mid-80s slider flashes solid sweeping action, of the four he had thrown on the season entering Sunday’s game, none were in the zone, and to be honest, they weren’t particularly close. Even at 100-plus mph, you can’t live on fastballs alone, and many will be watching Joyce for the remainder of the spring in an attempt to figure out exactly what the entire package looks like. –KG Read the rest of this entry »

Two weeks ago was Prospect Week here at FanGraphs. I didn’t contribute any analysis to it, because a) it was packed with really good analysis already and b) I wasn’t done compiling the thing I wanted to contribute. With some time to finish up my work — and not much else going on in our lockout-plagued sport — I’m ready to provide a bit of bonus analysis.

Last year, I used a variety of statistical techniques to come up with a list of players I thought stood a strong chance of putting together a meaningful major league career. This year, I’m … well, I’m using a variety of statistical techniques to come up with a list of players I think stand a strong chance of putting together a meaningful major league career. But this time, I’ve spent a bit more time refining my methods.

Here’s a quick overview of those methods. I used a variety of simple models based on historical minor and major league data. In each of them, I looked at a variety of key indicators in minor league hitters: statistics, age, position, level — anything I could download, essentially. I linked those minor league seasons to that player’s eventual major league career (or lack thereof).

This methodology carries many limitations, only some of which I have time to detail here. Baseball isn’t the same as it was in the past; while I think I’ve done a decent job of picking performance metrics that are stable over time, player development and the skills that are necessary to stick in the major leagues don’t look the same as they did 10 or 20 years ago.

That particular problem is inherent in everything that uses the past to predict the future, but don’t worry: my methods have way more shortcomings. For one, 2021 was a strange year to look at minor league statistics. With no 2020 season to gauge players’ skill levels, competition seemed far more variable within each league. I’m also basing much of this data on leagues that don’t exist anymore, as minor league realignment changed the makeup of the minor leagues significantly and also messed with my rudimentary park factors. I didn’t use Statcast or Trackman data, both because I don’t have a complete picture of it for 2021 and because it doesn’t exist at all in most of the years I used to train my various models. Finally, I’m using the position that each player played most in 2021 to give them a position, rather than where they’re projected to end up or what our prospect team thinks they’re best suited for.

Over the past several years, we’ve typically had about 1,500 players on The Board at any given time once all the org lists are done, spread across the tool’s pro, draft, and international sections. Heuristics play an important role in enabling us get a grip on such a large pool of players, especially when we are considering individuals for the first time, or trying to assess disparate players on the same FV scale.

For example, we felt comfortable absolutely stuffing Rockies right-handed pitcher Jordy Vargas near the top of their organizational prospect list in large part because of a key heuristic. I have not seen Vargas in person. He spent all of 2021 in the DSL, and didn’t come stateside for instructional league. Because the Rockies have struggled at the big league level and are therefore unlikely to be motivated to trade prospects, other teams have had little reason to thoroughly scout their DSL club, which makes sourcing detailed scout opinions about a player like Vargas difficult. Sometimes, a scout will come across a player like this at random and provide an in-person opinion that makes up the lion’s share of what we impart to readers, but in Vargas’ case, all we had was pitch data (which was how he got on our radar in the first place) and video we sought out from the 2021 DSL.

It can be challenging to drop Vargas right into the Rockies list for initial consideration, since he and someone like Ryan Vilade are apples-and-oranges in the extreme. It’s much cleaner to step back and compare Vargas, apples-to-apples, with same-aged pitching prospects across the global baseball landscape to get a sense of where he fits among that sub-group, assign him a FV grade in that context, and then move him onto the Rockies list. In Vargas’ case, his skill set is very similar to that of high school pitchers taken in the mid-to-late first round of a given draft (projectable 6-foot-3, gorgeous delivery, already throwing in the mid-90s, an excellent curveball), so we can use our heuristic FV for that type of player (in this case a 45) to get an initial sense of where he should be on the Rockies list even though I haven’t seen him, and then try to polish his grade from there. The foundations of most players’ evaluations on our site are built on heuristics like this and then augmented by other, more granular details. Read the rest of this entry »

Every offseason, we work diligently to produce prospect rankings for every team in baseball — when all is said and done, our lists typically incorporate well over 1,000 player write-ups. And based on the engagement with last week’s Top 100 Prospects list and our other Prospects Week content, our readers are as excited about prospects as we are. I’m proud of the work we do here at FanGraphs, but there is one area in which we haven’t done as well as we could, and that’s in helping you properly manage expectations.

We see it in the comments, on Twitter, and in pieces at other publications that reference the work done here. People line up a team’s prospect list and assume that is what the team will look like in two, three, or more years. Look up a system’s top five pitching prospects and that’s what the big league rotation will look like down the road. Three good middle infield prospects? That’s too many! What will the club ever do? We’ve tried our best to communicate the exceptionally real (and yet still underrated) failure rate when it comes to projecting prospects, but it’s become clear that we haven’t done a good enough job.

Mick Abel has a classic starter profile and a high ceiling. No. 20 on our recently-released 2022 Top 100 Prospects list, and No. 1 on our Philadelphia Phillies Top Prospects list, the 20-year-old right-hander features a four-seam fastball and a diving slider, plus offerings that he augments with a changeup and a curveball. Drafted 15th overall in 2019 out of a Beaverton, Oregon high school, the 6-foot-5, 205-pound hurler is, in the words of our prospect team, “a prototypical power pitching prospect with huge arm strength, a plus breaking ball, and the frame [to potentially grow into] a No. 1 or 2 starter.”

Abel discussed his repertoire, and his early-career development, over the phone last week.

David Laurila: How much have you learned about your pitches since signing with the Phillies?

Mick Abel: “I think I had a really good sense coming in, with how I was brought up with Kevin Gunderson back home. He was sharing the analytical side a lot better than a lot of kids would get from their pitching coaches. But I’ve definitely learned a lot. I’ve learned about things like seam-shifted wake, which is something I’ve asked about a lot.

“As far as my data goes, I haven’t tried to do too many crazy things with it. I know that I’ve got the stuff. It’s more so, ‘How am I going to maintain that, and not deviate too far off of what my normal numbers are?’”

Laurila: That said, have you looked to change any of your pitch characteristics? Read the rest of this entry »

Corbin Carroll is obsessed with baseball. He’s also immensely talented at the game he grew up playing in the Seattle area. Drafted 16th overall by the Arizona Diamondbacks in 2019, the 21-year-old left-handed-hitting center fielder is ranked 14th on our recently-released Top 100 Prospects list.

In the words of our prospect team, Carroll possesses “a blend of physical gifts and heady baseball acumen,” and is expected to “produce at an All-Star level for much of his career assuming a return to full strength.” Most notable in his tool grades are his running ability, which is 70/70 present and future, and his hitting ability, which is 70 future.

Carroll, who missed all but seven games of the 2021 season due to a shoulder injury, discussed his approach and hitting mechanics over the phone Wednesday afternoon.

David Laurila: Let’s start with a self-scouting report. Who are you as a player?

Corbin Carroll: “In my eyes… that’s good question. I’d say I like to view myself as a spark plug, someone who is getting the team going and will go the extra step to do whatever it takes to score more runs than the other team. I think that translates in terms of some tangible skills on the field, and maybe to some intangible ones, as well.”

Laurila: With intangibles in mind, do you see yourself as a team leader? Read the rest of this entry »
