Andrew Miller has an undeniably nasty slider. As a Red Sox fan, I remember it far too well from the 2016 postseason. Big Papi’s farewell tour didn’t seem all that fair when you consider the way the Red Sox ran into the buzz-saw that was Miller and the Cleveland Indians. Sure, I’m grateful for Miller helping the 2013 version of the Red Sox win a third world title since 2004, but come on Andrew, you had to ruin Papi’s goodbye?

With Miller’s recent signing with the St. Louis Cardinals, I found myself exploring his FanGraphs page. I stumbled upon this article, Andrew Miller on the Evolution of his Slider, and I instantly began to wonder if pitchers had similar experiences developing their sliders in the 2018 season. The first step in this analysis was to evaluate the evolution of Miller’s slider.

What jumps off the page is the change in velocity. Miller saw a 4.6 mph increase in his slider from 2011 to 2012, then another 3 mph added from 2012 to 2013. This in large part had to do with Miller moving from a starting role to a relief role during his time with the Red Sox. Given that information, however, an increase in velocity that drastic not only shows a pitcher’s willingness to adapt, but also a pitcher’s ability to adapt. By observing Miller’s slider splits, we see that ability to adapt almost immediately.

Heat. Smoke. Velocity. Stuff. Gas. Cheese.

I’m sure there are other words to describe our beloved “fireballers” (see, there’s another one). Pitchers who throw at high speeds are treated like fine china — see Stephen Strasburg in the 2012 postseason. I’m guilty of falling victim to the allure of a 98-mph fastball, regardless of its location. We love it, and, frankly, we’d like to see more of it. Major League Baseball has created a setting in which if a pitcher doesn’t break 90 mph with his fastball, he’s considered a “finesse” pitcher, or even a “soft-tosser” if left-handed. We love strikeouts, especially when a power pitcher blows a fastball by a hitter. But why?

Matt Harvey was stellar in 2015. He’s not so good anymore. Why do teams keep giving him second chances? Mostly because he throws hard.

However, it’s not entirely our fault. After reading Thinking, Fast and Slow by Nobel Prize-winning psychologist Daniel Kahneman, I began to understand why this happens. It shows how you can overcome cognitive bias, but in order to do so, you have to understand which one of your “thought systems” is making that decision for you. He explains that each human being has essentially two modes of thought.

System 1 – fast, instinctive, and emotional (gut feeling)

System 2 – slower, more logical (critical thinking) Read the rest of this entry »

When Statcast was launched, we were graced with incredible new stats such as Exit Velocity and Launch Angle, which revolutionized how we evaluate hitting. This new information confirmed obvious things like that Giancarlo Stanton hits missiles, but it also gave us a new breed of hitter. Daniel Murphy, Justin Turner, J.D. Martinez, and others looked at the data and made adjustments that started maximizing their power outputs. The standard evaluation method has become to look at EVs mixed with LAs to determine who is one tweak away from stardom. Hitting is a complex beast, with pitchers throwing 95-plus with nasty hooks to go with shifting defenses. Ultimately, a hitter is looking to produce solid contact regardless of where the ball goes. The goal of this analysis is to identify hitters who have an inefficient spray chart and see how they could optimize their profile by hitting more balls in a different direction to maximize production. Luckily with Statcast, we can now try to find these answers.

To do this analysis, I used Baseball Savant to gather 2018 Exit Velocity and xwOBA to Pull Side, Straight Away, and Oppo Side for all hitters with at least 50 plate appearances. I then used FanGraphs to pull the 2018 data for Pull%, Mid%, and Oppo% to discern how often a hitter attacks that field. I used 50 PAs as a filter since this is about where exit velocities become stable and helps weed out pitchers and other noise. This does create gaps in the data because some players didn’t register 50 PAs of a batted-ball direction. This dataset gives us the ability to look at how hard a hitter hits the ball to a field, what was their expected damage (xwOBA) to that field, and how often they went that way.

The first category I looked at was players who could use the opposite field more often. To do this, I looked at players who had an above average Oppo Side xwOBA and a below-average Oppo%. I used exit velocities to each field as a proxy to justify the directional swing change. Read the rest of this entry »

Far and away the most expensive current player on the Padres is Eric Hosmer, who has proven to be quite disappointing so far in his short time with the team. He’s due $21 million next season, which is three times the second-highest salary on the club. For a team that will almost certainly never have a payroll that compares with larger market teams, that’s a significant price to be paying.

Although he was signed in February of 2018 to be a cornerstone for the team, he promptly put up a mere -0.1 fWAR last season. He’s always been an inconsistent performer year-to-year, and this campaign was no exception. How could a player who put up 4.1 fWAR in value in 2017 see his level of play drop off so quickly in the following season? Can he bounce back in 2019 as he often does?

To begin, we need to know what held him back last season as a hitter. Hosmer’s a first baseman, so the majority of his value is going to be derived from his bat. Here’s a table showing the differences in his offensive production between the 2017-18 seasons:

This article was originally published on my blog, cargocultsabermetrics.com. 

Developing a new pitch can be a great way for a pitcher to have a breakout season. In 2018, we saw big improvements from Trevor Bauer adding a slider, Adam Ottavino adding a cutter, and Patrick Corbin adding a curveball. A new pitch can sometimes be the missing puzzle piece when trying to figure out why a player is good and not great. For Jose Berrios, a cutter might be that missing piece.

Examining Berrios’ arsenal

Jose Berrios has one of the nastiest curveballs in baseball. Instead of having the typical downward break associated with curveballs, Berrios’ curve averages 15.5 inches of glove-side break. This results from Berrios imparting gyro spin (think bullet spin) on his curveball rather than 12-6 top spin. Because of this, Berrios generates close to no vertical break caused by Magnus force, which is just a fancy way of saying the only drop we see on Berrios’ curve is due to gravity rather than top spin.

To pair with his curve, Berrios has a four-seam fastball which generates 9.5 inches of arm side run and 16.5 inches of upward vertical break due to Magnus force (causing the pitch to drop less), a two-seam fastball which generates 16.5 inches of arm-side run and 11.0 inches of upward vertical break, and a changeup with 14.5 inches of arm-side run and 5.5 inches of upward vertical break (the changeup will drop even more than the fastball since it is thrown slower and gravity will have more time to bring the pitch down).

Jurickson Profar finds himself at the top of the second base depth chart for the Oakland A’s, his new team following an offseason trade. That is very good news for Jurickson Profar, since it seems Jurickson Profar is struggling to throw the baseball.

The former top prospect made nine throwing errors in 2018… at two different positions. He made nine throwing errors at shortstop and nine throwing errors at third base. He also made one at second base, for a total of 19 throwing errors on the year. That is seven more than anyone else and the most in one season since the stat was first tracked in 2003.

Profar came up as a middle infielder, playing every game but one there in his minor league career. In 2018, he started at shortstop for the first three months of the season when Elvis Andrus got injured, and he struggled to throw the ball accurately. In mid-May, Levi Weaver of The Athletic was concerned Profar had the yips. In the article, Profar states how he’s struggled to make the transition defensively from Triple-A to the bigs:

“You know, this is the first time that I’ve gotten to play, for a long time, shortstop in the big leagues. Shortstop in the big leagues is not the same as shortstop in the minor leagues. You don’t get big guys like… Giancarlo Stanton, Aaron Judge, and Didi Gregorius…”

Profar was getting his first real chance to play shortstop in the majors, recognizing its difference from minor league ball, and thought he was benefiting from his time there. Just as he was getting his reps and starting to figure out the differences, the Rangers decided to move him to third base in July as Adrian Beltre’s hamstring acted up.

Profar started 46 games at third base, and the results weren’t great. He made as many throwing errors as Maikel Franco in half the innings. In an article published by Sportsday, former manager Jeff Bannister attributes Profar’s miscues to his lack of footwork:

“There are times when he gets a little out of rhythm,” Banister said. “That’s when you see those errant throws. … He continues to work on being consistent with the footwork.”

On a bunch of Profar’s errant throws this year, he seems unaware of the amount of time he has to make a play. He gets the ball very quickly out of his glove but the throws have a tendency to be off-line. He appears to be rushing his throws in situations that don’t warrant it. This goes along with his poor footwork. When he’s better able to recognize the amount of time he has to make a play, he can take the time to set his feet and make a proper throw to first base.

All that said, there are two main reasons that there is some hope for young Profar. Exhibit A is Marcus Semien, Profar’s new teammate. In 2015, Semien’s first year with Oakland, he made 18 throwing errors. The next season he made only eight, and his defensive numbers have continued to improve overall. Maybe there’s some coaches in Oakland who will be able to recognize a problem that the Rangers could not. It also doesn’t hurt that Matt Olson is one of the best defensive first basemen in the league. With that in mind, the change of location could really benefit Profar.

The other silver lining, and what you’ve probably been thinking this whole time, is that second base is a much easier throw. Profar played 79 innings at second base this year and made just one throwing error, coming on a play where he slipped, regained his footing, and then made a throw well wide of first. On plays in which he did not slip, Profar had a flawless record at second.

Even if Profar makes eight throwing errors this season at second base, the most made by any second baseman in 2018, that is fewer than half what he made last year. The Athletics currently have one of the best defensive infields in the game, and they are hoping they can help Profar stay on his feet and contribute with his arm.

When I was first asked about Chavez Young, I honestly vaguely recognized the name. I knew he was a Blue Jays outfielder, but that’s about it (and I work with prospects!). Just looking at the stat line, I was impressed. And the deeper I looked, the more I began to think that this might be the most criminally underrated prospect in baseball. David Laurila also took note recently here at FanGraphs.

Quick question: Who was the only prospect in baseball to record 50 extra-base hits and steal 40 bases in 2018? You guessed it: Chavez Young. Which prospect is rated as having the best defensive arm in the Blue Jays system by Baseball America, with 98 mph from the outfield recorded in high school? You guessed it again, Chavez Young. So how does a player like this go so under-the-radar? How does a 20-year-old in full-season ball who plays plus defense, hits third in his lineup, and had 50 extra-base hits and 40 steals not even make MLB Pipeline’s top 30 for the organization?

Let’s start off by saying who Chavez Young is. Young was born in the Bahamas, an area that is starting to get more buzz as a baseball country after producing prospects like Kristian Robinson and Jazz Chisholm. But it is also an area that up until recently was rarely visited by baseball scouts. Since 1983, only one major league player has made the MLB from the Bahamas (Antoan Richardson). As a result, Chavez left the Bahamas in high school to pursue baseball in the prestigious Georgia prep ranks. Read the rest of this entry »

Managers are always attempting to optimize their lineups for success. Whether they make in-game decisions like double-switches and lefty-righty matchups, or choose to change things up based on recent or historical performances, every move is meant to give their team the competitive advantage. What if they also made alterations based on pitcher groupings? In this article, I will attempt to determine if batter performance is impacted by pitcher clusters that are organized by pitch speed and pitch proportion.

The parameters used to cluster pitchers are below:

• Proportion of Pitch Thrown
• Average Pitch Speed

These statistics were calculated for the following pitch types:

• Changeup
• Curveball
• Eephus
• Cutter
• Four-seam fastball
• Sinker
• Two-seam fastball
• Knuckle-curve
• Knuckleball
• Slider
• Splitter

The Yankees kicked off their offseason by acquiring LHP James Paxton from the Seattle Mariners to bolster their starting rotation. You won’t find anybody willing to deny Paxton’s immense talent, but it’s natural for people to scrutinize big acquisitions, especially when the big acquisition is on his way to New York. This scrutiny is best exemplified by a conversation I had with my mother on the day the trade was made. My mom followed the Mets of the mid-to-late 1980s when she lived in Brooklyn, went years without watching baseball, and has watched the Yankees for the past decade by product of my fandom. This leads to the amusing circumstance that she is very familiar with current broadcasters Keith Hernandez and David Cone, all of the recent Yankees players, and almost nobody in between. Our conversation on the day of the Paxton trade went something like this:

Me: The Yankees picked up a hell of a pitcher named James Paxton. I think he’s going to do big things for the Yankees next year!

Mom: Yeah, sure. Isn’t that what you said about Sonny Gray?

Okay — she got me there.

Over the past several years, we have watched a number of hitters in the minors display good contact skills with average or below-average power be labeled with 45s and 50s only to burst onto the scene with an explosion of power they never showed any hint of previous. Mookie Betts might be the best example, along with guys like Jose Ramirez, who show up to the big leagues and announce themselves by mashing.  Naturally, prospect hounds, analysts, and the baseball community investigated how these guys went so overlooked (unless you were Carson Cistulli). It was surmised that contact quality mixed with good exit velocity and appropriate launch angles allowed hitters to maximize their output even without Aaron Judge levels of thump.

This investigation, however, is not a hunt for the next minor leaguer who will smash his way onto the scene, but rather a search for the pitchers who will try to stop them. With modern conditioning and institutions (read: Driveline) making it more possible than ever to gain velocity, one no longer must be naturally gifted a 6-foot-5 frame with easy 95 to be considered a prospect. Furthermore, with openers, bulk guys, firemen, and more, traditional pitching roles are going by the wayside.

This analysis attempts to seek out pitchers who possess above-average command or secondary offerings but lack the prototypical velocity grades we are seeing in today’s game. Identifying these pitchers would make them intriguing candidates for these high-intensity velocity training plans. While you may not find the next Luis Severino, you could uncover an explosive fireman reliever, matchup guy, or high-octane backend starter that pushes you closer to October glory.

The process for this analysis involved using the 2018 updated prospects list from THE BOARD, developed by Kiley McDaniel, Eric Longenhagen, and Sean Dolinar at this very site. I started by sorting for prospects who either currently have > 55 command or project for the same. This brought the sample to 85 pitchers. Next, I sorted out pitchers who have a present FB grade of > 55. Our sample now sits at 38 pitchers who have or project to have above-average command and an average-to-below-average fastball. Before diving into the next set of data, I wanted to provide some broader notes about this group. Notable pitchers with top 100–130 considerations on this list include Atlanta’s Kolby Allard and Joey Wentz, Miami’s Braxton Garrett, and the Angels’ Griffin Canning. There are 16 lefties and 22 righties. The Phillies lead the way with five of these guys, the Cubs and Rockies are tied with three each, and then the rest of the league has one or two on this list. Additionally, the average age of this group is 22.8 years old.

Now that we have our assorted pool, it is time to sort through this group’s off-speed arsenal. This part of the analysis was more subjective. I have attempted to group pitchers with similar traits that could fill a variety of roles. What follows is three tables of guys who could benefit most from additional velocity.

This first group features two right-handers with a current 60-grade pitch that projects for 70. Of the 38, these two are the lone members who feature a current 60 pitch. Of the two, Morgan has the higher upside based on his slider. Both have fastballs that sit around 90 mph, but additional velo training could push the value of these guys up a tier. Guys from this tier could be featured as openers or one-time-through-the-order relievers that rely on one elite pitch. The selling point of this group is that they have that elite pitch to lean on even without elite velocity.

The next group features players with multiple 55-or-better future offerings, led by Padres righty Pedro Avila, who is rocking two future 60-grade pitches. Previously mentioned notables Garrett and Wentz also fall into this category. This group represents backend starter types who are useful during the season but less useful during the postseason. Additional velo here could push these guys into strong No. 3 starters or high-leverage multi-inning guys.

The last group of guys profile as backend starter types who live on off-speed stuff and have no margin for error with their fastballs. I identified these players by adding their FV non-fastball pitch grades together, noted as ARS in table (ARS = FCH+FSL+FCB). These guys walk the command and off-speed tightrope to end up as backend starters in the best case, or just middle-relief guys or up-and-down starters. Occasionally these guys become Kyle Hendricks, Tanner Roark, or Doug Fister, but these are exceptions and not the rule. Almost everyone in this group is older for a prospect, so the ceiling is limited, however, additional velo for these guys could turn them into more dynamic multi-inning relivers, bulk guys, or high-end No. 4-5 starters.

I should also note that all these guys fall into different buckets of age, level, and body types. Arguably, the most critical component of a prospect on this list would be targeting high-makeup guys who would be willing to experiment and acknowledge that they could use more gas to ascend to the next level. Some of these pitchers may be maxed out physically or unwilling to change what already seems to work. This analysis also looks past statistical performance, level, and even present pitch value a bit. What this analysis does do is identify guys who could rapidly improve with additional velocity due to advanced command and secondary. The margin for error is incredibly slim for this type of pitcher, but through intense training and velocity gains, pitcher X throwing 90-92 bumping to 94-96 with already above-average command and secondaries would vault them into a new tier of player. For teams looking to squeeze every ounce of value out of their farm system, this could be another way to target undervalued talent that has yet to be unlocked and developed.
