I wish I could come to you with news about the mass adoption of backup sliders from pitchers across the league. I also wish I could come to you with a shining example of even one player who has perfected the art of the effective mistake. There is no apparent analytical case that comes to mind; it’s largely just a fascination to me — the best hitters in the world swinging through the worst offering a pitcher could imagine throwing. Here’s an example:

Matt Wisler is the perfect guy to have here — someone who throws nothing but sliders making the biggest kind of slider mistake! And yet there are times when it just works. What I want to try to answer is what makes these mistake sliders click without diving into the rabbit hole of pitch sequencing. Are there particular characteristics of movement and velocity that make for better backup sliders?

First, we have to set guidelines on what a backup slider is. You know it when you see it, but it is more broadly defined as something that “hangs” when thrown to a batter of the same handedness. Sliders behave differently depending on whether they’re thrown inside or out, as shown by Eno Sarris on this site a few years back; those away gain almost half a foot of horizontal movement compared to ones thrown inside! Sliders need height to be considered mistakes, but the distinctions in horizontal movement are too vast for an outside-and-up slider to be as bad a mistake as one up but inside. For our purposes, let’s say that a backup slider is anything in the upper third of the strike zone, middle-to-in, in a same handedness matchup. Read the rest of this entry »

Eli Morgan has “a bugs-bunny changeup.” That’s how the 25-year-old rookie right-hander’s signature offering was described when it was suggested that I interview him for the Learning and Developing a Pitch series. Delivered at an average velocity of 75.1 mph, Morgan’s changeup is the slowest among pitchers who have worked at least 40 innings (not including Seattle’s Paul Sewald, who per StatCast has thrown just one changeup all season).

Cleveland’s eighth-round pick in the 2017 draft, Morgan has made 14 starts and has a 5.48 ERA and a 5.01 FIP to go with 68 strikeouts in 67.1 innings. He’s thrown his changeup — a pitch he described in detail this past Sunday — 22.4% of the time.

Eli Morgan: “I started out mainly fastball/breaking ball, and then my senior year of high school I began developing my changeup. I’d thrown a splitter — that was my changeup for my first couple years of high school — but I figured that probably wasn’t great for my arm going forward. At the time, there was talk of Masahiro Tanaka having issues with his elbow because of the splitter, and that kind of turned me off of that pitch. I decided to go to a regular circle change.

“When I got to [Gonzaga University] they told me that if I wanted to pitch, let alone be a starter, I needed to have a good changeup. That was a big thing up there, so I started throwing it a lot more and got comfortable with it.

“Because I throw a four-seam fastball, I throw a four-seam changeup. That’s something one of my pitching coaches mentioned: ‘Make sure it comes out with the same seams as your fastball.’ That’s what I went with, and I had pretty good command of it right from the start. Over time, I began getting more movement on it, getting more fade. Read the rest of this entry »

I recently sourced scouting info and wrote about prospects (and rehabbing veterans) who contending American League teams have on the way during the season’s final stretch, players young and old who lurk beneath the big league surface and might yet make an impact on who hoists the Commissioner’s Trophy at the end of the season. Today, I examine the National League.

NL East
I have very little to pass along regarding the Braves. Their Triple-A pitchers on the 40-man (Kyle Wright, Kyle Muller, Tanner Roark) have been up and down throughout the year and they haven’t looked appreciably different since they were last up. Chris Martin and Josh Tomlin went on the injured list very recently and haven’t had a chance to rehab yet. The same goes for Jasseel De La Cruz, who had several rough starts in August before hitting the IL. Yoan López, acquired from the Diamondbacks earlier in the year, has been sitting 95-98 with Triple-A Gwinnett, but his fastball’s lack of movement means it doesn’t miss many bats. His slider is still plus when located properly, though. He’s the lone 40-man member in Gwinnett’s bullpen, though Dylan Lee (throwing strikes, up to 96, lots of in-zone fastball whiffs) has out-pitched him, and Jesse Biddle and Víctor Arano both generate more whiffs than López does. They all might be ahead of him in the pecking order for big league time in case of injury, even if it means making a 40-man move.

The Phillies have a mix of rehabbers and prospects lurking in the minors, with the prospects presenting low-impact/emergency options right now. Young Francisco Morales (who has projected as a reliever for us at FG since signing) has struggled as a starter all year at Double-A Reading, walking 59 in 70 innings pitched. He doesn’t seem to be on the fast track, even in a bullpen role. Read the rest of this entry »

Louis Head has had a storybook season. Without a team during last year’s pandemic summer, the rookie right-hander was working a sales job, his dreams of reaching the big leagues seemingly in the review mirror. Nearly a decade after being taken by Cleveland in the 18th round of the 2012 draft, he thought his career was over. Then the Tampa Bay Rays came calling.

Head was signed off the scrap heap this past February, and on April 25, two days after celebrating his 31st birthday, he made his major league debut. The Katy, Texas native has gone on to appear in 20 games with the Rays since then — he’s also seen action in 24 games with Triple-A Durham — logging a 2.93 ERA and a 3.53 FIP over 27-and-two-thirds innings. His slider has played a big role in his Cinderella ascent. Developed since joining his new team, the pitch has helped fuel one of the better success stories of the 2021 season.

David Laurila: You’re a 31-year-old rookie. How were you able to finally take that final step and reach the big leagues? Was pitching development part of it?

Louis Head: “I think it was mostly about there being an opportunity here. We had some guys get hurt early on in the season, and it opened up some doors for me. That didn’t really happen in the past with other organizations. I felt like I had thrown well in the past, especially for Cleveland, and I could have been a guy they brought up. But those opportunities never happened.

“Development-wise, when I did get here, working with the analytical team, and with [pitching coach] Kyle Snyder, we were really able to develop my slider into a major weapon. Before, it was just kind of a get-me-over pitch. Now it’s a legit put-away pitch, and that’s made a world of difference. Them having confidence in me has been a huge part of my success, as well.”

Laurila: Why were you able to turn the corner with your slider here, and not with Cleveland, the Dodgers, or the Mariners? Read the rest of this entry »

When the Braves signed Ronald Acuña Jr. and Ozzie Albies to phenomenally team-friendly contracts before the 2019 season, two distinct possibilities loomed. First, the team could bank the money they saved and put out a good team at a discounted price. Second, they could reinvest those savings and attempt to put together a great team. Which they chose would say a lot about how the team planned on operating long-term.

The question is no longer open. The Braves have overcome a season-ending injury to Acuña to surge to the top of the NL East, and while the Phillies and Mets continue to nip at their heals, they’re well on their way to a fourth straight division title. They’ve done so thanks to some new young contributors — Austin Riley and Ian Anderson have come into their own this year. They’ve made some savvy signings and trades — Charlie Morton has been their best pitcher this year, and Jorge Soler has been excellent since joining the team.

Now, the Braves are making moves to prolong their stay atop the division. In late August, they signed Travis d’Arnaud to a two-year extension. They followed that up by signing Morton to a one-year deal (both contracts have team options tacked on). Let’s take a look at both of those deals, as well as how they affect the team’s outlook for next year and beyond.

Signing d’Arnaud to an extension — two years and $16 million with a team option for a third year — was hardly an obvious move for the team. He missed the majority of the season after tearing a ligament in his thumb in May. He’s hit well since his return, but even so, his seasonal line works out to an 84 wRC+. Combine that with solid receiving, and the total package works out to a roughly average catcher.

What made the Braves so eager to lock d’Arnaud up? His replacements fell well short of that average catcher bar. On the year, Atlanta’s catcher position has produced -1.4 WAR, the worst mark in the majors. It’s not an individual problem; a huge array of catchers have combined to weigh the position down:

Relative to that mess, d’Arnaud is a huge improvement. That’s not to say that Contreras won’t figure it out, or that Vogt isn’t a capable backup. But for a team with an embarrassment of riches at most positions, giving away so much value at catcher doesn’t make sense. It gets worse: the list of free agent catchers this offseason is nasty, brutish, and short. Yan Gomes and Martín Maldonado are the headliners, and it gets worse from there. Miss signing your target, and you might be in for a long offseason. Read the rest of this entry »

The Wild Card races in both leagues continue to be the source of all the drama down the stretch. There are a handful of teams vying for those last few playoff spots and the competition should go come to the wire. And as we witnessed last weekend, the Giants and Dodgers battling over the top of the NL West should provide a ton of excitement, too.

A quick refresher: my approach takes the three most important components of a team — their offense (wRC+), and their starting rotation and bullpen (50%/50% FIP- and RA9-) — and combines them to create an overall team quality metric. I add in a factor for “luck” — adjusting based on a team’s expected win-loss record — to produce a power ranking.

(All stats through 9/5)

Entering their final head-to-head matchup of the season, the Dodgers and Giants were tied atop the NL West standings and had played to an extraordinary balance in their previous 16 games: they had each won eight games and scored exactly 68 runs against each other. A dramatic 11-inning Giants win on Friday night was a fantastic start to this battle of titans. Alas, the remaining two games in the series were far less climactic, with each team winning a game comfortably. That final series win gives San Francisco home field advantage in case of a potential tiebreaker to decide the NL West at the end of the season. Read the rest of this entry »

Two weeks before the trade deadline, I shared a depressing series of projections for the Mets based on Jacob deGrom’s health. The team’s ace, who spent much of the early going making a run at Bob Gibson’s modern ERA record, had been sidelined by forearm pain and tightness, though he was reportedly returning soon. Still, you never know with either pitcher injuries or the Mets, so I decided to run some numbers on what New York’s fortunes would look like with either minimal or no deGrom. The results were … less than reassuring for the folks in Queens.

Me: ZiPS, without knowing precisely what deGrom's outlook is, would you say it's time for Mets fans to crack each other's heads open and feast on the goo inside?

ZiPS: Yes I would, Dan. pic.twitter.com/teimAJsmak

The “worst-case scenario” had the Mets retaining a 37% shot of making the playoffs; that turned out to be excessively sunny. A team that once held a 55–48 record and a four-game lead in the NL East as July turned to August is now in tatters, with a 14-21 record since then and trailing both Atlanta and Philadelphia in the division. As for deGrom, he had a setback not long after the deadline and still hasn’t returned to the active roster (and may not return at all this season). As of Tuesday morning, New York’s chances are down to 6.8% in our projected standings, and ZiPS is barely more bullish at 7.1%. The Mets don’t need much to go wrong to end up playing golf in October.

The Learning and Developing a Pitch series returned this summer after being on a year-long hiatus due to the pandemic. Each week, we’ll hear from three pitchers on a notable weapon in their arsenal. Today’s installment features a pair of right-handers, Joe Barlow and Bailey Ober, and a southpaw, Alex Young, on one of their breaking balls.

Joe Barlow, Texas Rangers

“I was a fastball-curveball guy until last year. The pandemic happened, then I went to Driveline to see if there was an opening for a better pitch… not even a better pitch, just any pitch in general to add to the repertoire. That way, if my curveball wasn’t on, I wouldn’t just be throwing fastballs.

“I played with changeups, two-seamers, sliders, and cutters. The pitch that I could seemingly best repeat was the slider. Even though it wasn’t good, it seemed like there was an opportunity to grow on that and get it to be a pitch that I could use. So, I went into the offseason and started throwing it. It was meant to be a third pitch — behind the curveball, behind the fastball — but I ended up getting a good feel for it and now it’s almost 50-50 with the fastball. Read the rest of this entry »

I am not going to beat around the bush: Luis Castillo had a miserable start to the season. On Opening Day against the Cardinals, he allowed 10 runs (eight of which were earned) and recorded zero strikeouts in just three and a third innings of work. He bounced back about a week later against Pittsburgh, tossing seven innings with five strikeouts versus one walk without surrendering a run. But despite that showing, Castillo’s Opening Day struggles proved to be more than a blip on the radar for a pitcher who ranked among the top 20 in baseball over the three seasons prior to 2021. At the beginning of May, Castillo still had an ERA above six (6.07); it would not dip below that mark until his June 15 start against Milwaukee. His ERA peaked (apart from the stretch between his first and second start) at 7.61 on May 23. As of this writing, his ERA is 4.20; he has accumulated 3.0 WAR over 163 innings, placing him 26th in the majors among qualifiers.

So what has changed? Back on May 18, Justin Choi wrote about Castillo’s performance through his first eight starts, attempting to diagnose what plagued the Reds right-hander. Justin first looked at Castillo’s changeup, which had long been his most effective offering but which was generating far fewer whiffs than before. Justin found that the pitch was dropping more than it had in the past, though Castillo was still able to locate it just below the lower edge of the strike zone. The rest of Castillo’s repertoire (a sinker, four-seamer, and slider), on the other hand, was being placed right down the pipe. Justin concluded that the location of Castillo’s changeup were so different from that of the rest of his pitches that batters were either laying off the changeup or swinging at the few that landed closer to the heart of the zone.

Since Justin published his analysis, Castillo has compiled a 3.15 ERA and ranks 10th in WAR. Let’s try to locate the difference. Year-over-year, his pitch mix is largely the same:

The Class of 2020 has had a long wait for induction into the National Baseball Hall of Fame, and not just because the coronavirus pandemic set the festivities back nearly 14 months. While Derek Jeter was resoundingly elected in his first year of eligibility, the road to Cooperstown for the other three honorees — Ted Simmons, Larry Walker, and the late Marvin Miller — was more like a maze, full of wrong turns and apparent dead ends. That road finally ends on the afternoon of Wednesday, September 8, when all four will be inducted into the Hall. As somebody who has been deeply invested in the careers and candidacies of all four, I couldn’t bypass the midweek trip, even under pandemic conditions.

“There was never any thought in my head that [my election] was going to happen. So to be completely honest, I didn’t pay much attention,” said Walker during a Zoom session with reporters last Thursday, referring to the annual BBWAA voting. During his first seven years of eligibility, he maxed out at 22.9% of the vote (2012), and dipped as low as 10.2% (2014).

Even those meager showings surpassed Simmons, who received just 3.7% in 1994, his first year of eligibility. “Back then, you were literally off the ballot. And you know, there was really no vehicle at that time that I knew of or heard of that would enable you to come back,” he said during his own Zoom session, referring to the so-called “Five Percent Rule” that sweeps candidates who fail to reach that mark off the ballot.

Simmons could be forgiven for not knowing the ins and outs of the Hall’s arcane election systems. That he even made it onto an Era Committee ballot to have his candidacy reconsidered for the first time in 2011 was itself groundbreaking. As longtime St. Louis Post-Dispatch writer Rick Hummel, who has served on several iterations of the Historical Overview Committee that puts together such ballots, said in 2015, “The first question these Hall of Famers ask you is, ‘How many ballots was he on for the writers’ election? One? They must not have liked him very much.’” Read the rest of this entry »
