If you follow the work of Alex Chamberlain at all, you’ve heard of the value of launch angle consistency. I’m not going to recapitulate his body of work on the subject, but briefly: hitters with tighter launch angle distributions routinely run higher BABIPs, and you can think of launch angle consistency as roughly a proxy for “hit tool.”

Most of this comes down to avoiding terrible batted ball outcomes. The two worst things you can do when you put the ball in play are to hit it straight down or straight up. Given that balls are, on average, hit mostly forward and with a tiny bit of loft — breaking news, I know — launch angle consistency is a great proxy for how often you avoid those, because the more -80s and +80s you put in your sample of mostly 10s and 20s, the higher the standard deviation gets.

One thing I’ve often wondered is whether this idea of consistency holds up for subsets of batted balls. Intuitively, it seems like it might. Take hard-hit balls, for example. If you’re hitting the ball 95 mph or harder, you really don’t want to squander it by hitting the ball on the ground or straight into the air. The distribution peaks at 30 degrees, but anything between 10 and 35 is a solid outcome.

With this in mind, I decided to look for batters who grouped their hard-hit balls most tightly. Having a narrow distribution seems like a great way to maximize good outcomes. Which player, you ask, has the tightest launch angle consistency (I’m just using standard deviation here) on hard-hit balls? I’m glad you asked — it’s Dee Strange-Gordon.

There are baseball stars, there are heroes and legends, and then there is Henry Aaron. The slugging right fielder is remembered mainly for surpassing Babe Ruth’s all-time home run record on April 8, 1974, but even that crowning achievement obscures the all-around excellence and remarkable consistency he demonstrated during his 23-year major league career.

What’s more, Aaron’s accomplishments can most fully be appreciated only with an understanding of the racism he encountered throughout his life and his career, as a Black man who began his professional career in the Negro Leagues, who became a star before half of the teams in the National League had integrated and a champion before the last teams in the American League did so, who emerged as a force for civil rights while becoming the first Black star on the first major league team in the Deep South, who surpassed the most hallowed record produced by the game’s most famous player while facing a nearly unimaginable barrage of hate mail and death threats, and who broke down further barriers after his retirement, as one of the game’s first Black executives and as a critic of the lack of diversity among managers and executives.

More than a Hall of Famer, Aaron was a true titan, an American icon in his own right. Sadly, he is the latest Hall of Famer in an unrelenting stretch to pass away. News of his death was announced on Friday morning, four days after that of Don Sutton, 15 days after that of Tommy Lasorda, and 27 days after that of former teammate Phil Niekro. He was 86 years old, and had been in the news earlier this month as he received a COVID-19 vaccination.

“Hank Aaron was one of the best baseball players we’ve ever seen and one of the strongest people I’ve ever met,” said former president Barack Obama in a statement released on Friday. Former presidents Jimmy Carter, Bill Clinton, and George W. Bush paid tributes in statements as well, as did President Joe Biden:

While Aaron’s story is often cast as that of a man overcoming or ignoring racism and hatred to achieve greatness with quiet dignity, it does the man a disservice to soften his edges and diminish the pain that he felt, and the scars that he bore — particularly given that he did not do so in silence. Surpassing Ruth “was supposed to be the greatest triumph of my life, but I was never allowed to enjoy it. I couldn’t wait for it to be over,” he once said. “The only reason that some people didn’t want me to succeed was because I was a Black man.” Read the rest of this entry »

Sunday, the Pirates traded starter Jameson Taillon to the Yankees for a package of four prospects. Dan Szymborksi will provide in-depth analysis of the deal as it pertains to the Yankees soon, though I’ll note to start that with the return of Luis Severino and Domingo Germán and the additions of Corey Kluber and now Taillon, the Yankees rotation will be reliant on several high-risk, high-reward starters this season.

Of course, nobody likes trading away good big leaguers, especially those who the club and city care about for reasons beyond their on-field performance. Taillon has persevered through a lot, including testicular cancer and an August 2019 Tommy John, the second such surgery of his career. When he next steps on a big league mound, it will have been nearly two years since he last did so. That layoff (he has been throwing live BP to hitters since late last summer and has been throwing bullpens during the offseason) creates volatility that mirrors the added volatility of this particular prospect package. Taillon could be an anchor of the Yankees rotation next year or might be a shell of himself. Regardless of which he would have been in Pittsburgh, the Pirates are not ready to compete and so I think they did well to trade him for four good prospects today, acquiring upside but also mitigating risk by getting several players in return.

On to those prospects. The quartet heading back to Pittsburgh — righties Miguel Yajure (age 22) and Roansy Contreras (21), 21-year-old outfielder Canaan Smith-Njigba, and 18-year-old shortstop Maikol Escotto — is a pretty exciting. Read the rest of this entry »

Mitch Keller has only thrown 69-and-a-third big-league innings, and he’s already had a remarkable career. The baseball gods are a big reason why. In his 2019 rookie season, the now-24-year-old Pittsburgh Pirates right-hander had a 7.13 ERA to go with a 3.19 FIP, and this past season he had a 2.91 ERA to go with a 6.75 FIP.

Hello, BABIP.

In an almost-inexplicable quirk of fate, Keller followed up a .475 BABIP — the highest one-season mark in MLB history — with a .104 BABIP in 2020. No pitcher who threw 20-or-more innings in last year’s pandemic-truncated campaign had a smaller percentage of balls put in play against him fall safely to the turf. This happened with an average exit velocity of 88.5 mph, which was higher than the 87.6 he’d allowed in 2019.

Ben Lindbergh wrote about Keller’s snake-bit season for The Ringer last spring, and the conversation they had prior to publication is what brought the data to the fore.

“I remember getting off that phone call and looking it up myself,” said Keller. “I was like, ‘Oh, my goodness. That’s crazy.’ I knew that I had a high BABIP, but I had no idea it was the highest in history. Once he told me, it wasn’t like I was coming back to the dugout thinking, ‘Man, I think I’m having some bad luck.’ It was actually on paper, as a stat. It was, ‘No, seriously. I was having bad luck.” Read the rest of this entry »

Don Sutton did not have the flash of Sandy Koufax, or the intimidating presence of Don Drysdale. He lacked the overpowering fastball of Nolan Ryan, and didn’t fill his mantel with Cy Young awards the way that Tom Seaver or Steve Carlton did. He never won a World Series or threw a no-hitter. Yet Sutton earned a spot in the Hall of Fame alongside those more celebrated hurlers just the same. He was one of the most durable pitchers in baseball history, as dependable as a Swiss watch.

Alas, durability does not confer immortality. Sutton died on Monday at the age of 75, after a long battle with cancer. Son Daron Sutton, a former pitcher and broadcaster in his own right, shared the news on Twitter on Tuesday:

Saddened to share that my dad passed away in his sleep last night. He worked as hard as anyone I’ve ever known and he treated those he encountered with great respect…and he took me to work a lot. For all these things, I am very grateful. Rest In Peace. pic.twitter.com/cvlDRRdVXa

Sutton is already the second Hall of Famer to pass away in 2021. His former manager, Tommy Lasorda, died on January 7. Both deaths follow a year in which a record seven Hall of Famers died. Friends, we’ve got to stop meeting like this.

In a career that spanned 23 years and was bookended by stints with the Dodgers (1966-80, ’88), with detours to the Astros (’81-82), Brewers (’82-84), A’s (’85), and Angels (’85-87), Sutton started 756 games, more than any pitcher besides Young or Ryan. The wiry, frizzy-haired righty listed at 6-foot-1 and 185 pounds not only avoided the Disabled List until his final season at age 43, he never missed a turn due to injury or illness until a sore elbow sidelined him after his penultimate start in the summer of 1988. Upon retiring, he went on to a successful second career as a broadcaster, primarily with the Braves.

Like Lasorda, Sutton occupied a special place in this young Dodger fan’s life. I was nine years old and riding in the way-back of my family’s maroon-and-faux-wood-panel Chevy Caprice station wagon on a road trip to California on August 10, 1979 when my father conjured up a radio broadcast of the Dodgers game. It was my introduction to the golden voice of Vin Scully, who shared booth duties with Jerry Doggett, calling Sutton’s franchise record-setting 50th shutout, a 9-0 victory over the Giants fueled by a Derrel Thomas grand slam and Mickey Hatcher’s first career homer. You could look it up. Thereafter, no matter where he roamed, I always rooted for Sutton, and grew to love the wit and brutal honesty that accompanied his workmanlike approach and made him eminently quotable, during and after his career.

“Comparing me to Sandy Koufax is like comparing Earl Scheib to Michelangelo,” he once said after surpassing his former teammate on some franchise record list. Read the rest of this entry »

Hey there! I want to give you a heads up about this article, because it doesn’t fit into a normal genre I write. Today, I won’t be telling you some new insight about a player you like, or creating some new nonsense statistic that tries to pull meaning from noise. This is a story about how baseball analysis is changing right before our eyes. A group of scientists and baseball thinkers are redefining the way we think about pitch movement, and I think it’s worth highlighting even if I don’t have anything to add to the conversation yet, because this new avenue of research is going to be front and center in Statcast-based analysis over the next few years.

“Seam-shifted wake,” as Andrew Smith, a student of Dr. Barton Smith (no relation) coined it, is a source of pitch movement that the first attempts at understanding the physics of a pitched baseball overlooked. It has already changed the way that coaches and pitchers approach pitch design, and due to recent data advances, it’s about to be everywhere. So let’s go over how we got here, to this newly observable way that pitchers deceive hitters, by starting at the beginning and working forward.

At its core, baseball is a game about one person trying to throw a ball past another person. There are other trappings — bases and baserunners, umpires, a strike zone, the mythology of Babe Ruth, and a million other sundry things. At the end of the day, though, everything starts with the pitcher trying to throw a ball past the batter.

Accordingly, baseball analysis over the years has focused on describing the flight of that ball. For a time, that simply meant describing the shape of pitches — they don’t call them curveballs for nothing. The next step was velocity — radar guns let us appreciate fastballs numerically rather than merely aesthetically.

In the past 15 years, the amount and scope of pitch-level analytical data has exploded. First, PITCHf/x quantified pitch location and movement. When we report a pitcher’s chase rate or how often a batter swings at pitches in the strike zone, it’s because the location where each pitch crosses the plate is recorded and logged. When we say a pitcher has eight inches of horizontal break on their slider, it’s because new technology allows us to measure it.

When Statcast debuted in 2015, it added another wrinkle: radar tracked the spin rate of each pitch in flight, putting a numerical value on something that had previously been only qualitative; a pitcher’s ability to generate movement through spin. Doctor Alan Nathan has written several authoritative studies discussing the value of this spin data. Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the Toronto Blue Jays. Scouting reports were compiled with information provided by industry sources as well as my own observations. As there was no minor league season in 2020, there are some instances where no new information was gleaned about a player. Players whose write-ups have not been altered begin by telling you so. For the others, the blurb ends with an indication of where the player played in 2020, which in turn likely informed the changes to their report. As always, I’ve leaned more heavily on sources from outside the org than within for reasons of objectivity. Because outside scouts were not allowed at the alternate sites, I’ve primarily focused on data from there. Lastly, in effort to more clearly indicate relievers’ anticipated roles, you’ll see two reliever designations, both in lists and on The Board: MIRP, or multi-inning relief pitcher, and SIRP, or single-inning relief pitcher.

For more information on the 20-80 scouting scale by which all of our prospect content is governed, you can click here. For further explanation of Future Value’s merits and drawbacks, read Future Value.

All of the numbered prospects here also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It can be found here.

Editor’s note: This post has been updated to resolve language in Nate Pearson’s blurb that conflicted with his FV.

One of the big puzzle pieces of this offseason fell firmly into place Tuesday night as the Toronto Blue Jays came to terms on a six-year, $150 million contract with free agent outfielder George Springer. Springer, our second-ranked free agent overall, is coming off a .259/.359/.540, 1.9 WAR season in the abbreviated 2020, enough to make him a highly desired player despite the fact that he’ll turn 32 at the end of the 2021 season.

It seems almost like yesterday when I was fielding questions in my chat about whether Springer was a highly touted prospect-turned-bust after a rough first two weeks in the majors that featured a sub-.500 OPS and strikeouts in a third of his plate appearances. In fact, my standard, curt “April” reply originated in response to the initial panic caused by his slow debut. As one would expect from a player with his pedigree, April showers brought May power, and by the end of his second month in the bigs, Springer’s seasonal OPS was up to a much healthier mark in the mid-.800s. His OPS stayed at or above .800 until he was finally stopped in July due to a quad injury that cost him the rest of the 2014 season.

That was pretty much the last thing that stopped him. Starting in 2015, his first full season, Springer hit .274/.363/.494 and 154 homers and 24.7 WAR for the Astros. That’s not even counting his playoff appearances, another half-season of the highest-leverage baseball you can find, where Springer flourished, hitting .269/.349/.546 over those 63 postseason games. His 19 postseason home runs are currently tied for fourth in major league history, though admittedly, there are a lot more playoff games now than when Ted Williams played. All told, Springer’s performance has easily put him in the top 10 among outfielders in recent years. Read the rest of this entry »

On (day of week), the Padres acquired (talented pitcher) from the (spendthrift team) in exchange for a seeming pittance, including (name of decent but not overwhelming Padres prospect). Now, surely, AJ Preller is done. Or is he?

Oh, hello there! Sorry about that. That’s actually the Mad Libs-esque form that I normally use to cover Padres pitching transactions. Today, I’ve got some details for you. It’s Joe Musgrove heading to the best weather in baseball, Hudson Head and Endy Rodriguez highlighting the group headed out (in a three-team trade involving the Pirates and Mets), and Andrew Friedman gently whispering words of affirmation to himself: “We’ll still win the long game, we’ll still win the long game, the Dodger Way can’t be beat.”

Musgrove isn’t an ace, at least not in the way that new teammates Yu Darvish and Blake Snell are. He would have been Pittsburgh’s number one starter this year, which isn’t the same thing. In San Diego, he’ll slot in as the Padres fourth starter. Let the words of Anakin Skywalker speak for the rest of the NL West: “This is outrageous! It’s unfair!”

Seriously, take a look at our Depth Charts predictions for the Padre rotation:

There simply aren’t other teams throwing out pitchers like Musgrove after a whopping three other pitchers. We think that the Padres, Yankees, and Mets will accrue roughly equal value from starting pitchers next year, but the New York teams are doing it with Gerrit Cole and Jacob deGrom, the consensus best two pitchers in the game. Yu Darvish is nice, but not that nice. The Padres are building their own Death Star rotation, and they’re doing it with volume. Read the rest of this entry »

The Yankees’ big free agent signing last week came when the team brought back DJ LeMahieu for six years and $90 million. That deal raises both the floor and the ceiling in the Bronx next season. LeMahieu is a dependable player who should be average at a minimum, ensuring the infield doesn’t have a black hole, while a repeat of his performance since the beginning of 2019 would elevate the Yankees’ chances of a great season. The Yankees’ other signing last week came late Friday in the form of Corey Kluber. Kluber does less to shore up the Yankees’ floor given his recent injury history; indeed, there’s a non-zero chance Kluber doesn’t contribute much to the Yankees at all this year. What Kluber and his two Cy Young awards do manage to do is substantially raise the Yankees’ ceiling, as the team should face a tough battle in the AL East.

Jeff Passan was first with the news that Kluber would be signing with the Yankees for one year and $11 million. Kluber’s contract sits between my $9 million prediction and the $12 million median crowdsource estimate from our top 50 free agent ranking. Despite making just eight starts over the past two seasons, including just a single inning last year, a couple factors worked in Kluber’s favor in securing a decent pillow contract. The first is that Kluber threw for scouts and impressed. The second relates more specifically to the Yankees.

1/When it comes to Kluber, no team will have a better understanding of his physical condition than the #Yankees. The mound session today was at Cressey Sports Performance. The rehab is being done by Eric Cressey, who also is the NYY’s director of health and performance.
