Less than four weeks remain in the 2021 regular season, and while the coronavirus pandemic continues due to the Delta surge, MLB is back to some semblance of normalcy (though don’t tell that to the Red Sox). We’ve got a 162-game regular season, a comprehensible 10-team postseason format, the possibility of actual tiebreaker games being played if necessary — all of which were off the table last season — and no neutral sites. We’ve got some real playoff races as well, with the potential to produce end-of-season chaos.

Welcome back to Team Entropy. If you’re new here, don’t worry, I’ll catch you up.

A decade ago, during the wild 2011 races that resulted in the Rays and Cardinals snatching spots away from the collapsing Red Sox and Braves, respectively, on the season’s final day, I coined the phrase “Team Entropy” — taking a page from the Second Law of Thermodynamics, which states that all systems tend toward disorder — to describe the phenomenon of rooting for scenarios that produced such mayhem. I’ve returned to the concept annually, tracking the possibilities for end-of-season, multi-team pileups that would require MLB to deviate from its previously scheduled programming.

The idea is that if you’re a die-hard fan of a team trying to secure (or avoid blowing) a playoff spot, flag-waving for your squad of choice takes precedence, but if you’ve embraced the modern day’s maximalist menu of options that allow one not just to watch scoreboards but also to view multiple games on multiple gadgets, you want more. More baseball in the form of final-weekend division and Wild Card races. More baseball in the form of extra innings and tiebreaker scenarios topped with mustard and sauerkraut (though alas, the dastardly Manfred Man will still be mucking up those tiebreakers if they go past nine innings). You have TVs, laptops, tablets, and phones stacked like a Nam June Paik installation so you can monitor all the action at once. You want the MLB schedule-makers to contemplate entering the Federal Witness Protection Program instead of untangling once-far-fetched scenarios. If all that sounds familiar, you’re one of us.

I’ve always been a huge Darin Ruf fan, so getting to write about his 2021 success is a little bit more meaningful to me than it would be for almost any other player. Ruf is the last player I remember my grandfather singling out before he passed away, with the thought that Ruf, then a young prospect in the Phillies system, had the potential to be a productive big leaguer for our favorite team.

That was nine years ago. The Phillies promoted Ruf in late 2012 for his first cup of major league coffee, but he never amassed more than 297 plate appearances in any season for them. The bat was decent — Ruf posted a 105 wRC+ over 833 plate appearances, including a 125 wRC+ during his 2013 rookie season — but poor defensive numbers kept him barely above replacement-level in almost 300 games with Philadelphia. He was traded to the Dodgers in November of 2016, and even before he had an opportunity to make his organizational debut, Ruf’s contract was purchased by the Samsung Lions of the KBO. For three years, he raked in Asia, earning himself a minor league deal with the Giants for the pandemic-shortened 2020 season. (I was pretty excited.) A year later, he’s now the best hitter on a playoff-bound team (Kris Bryant is a notable omission from this list — he has a 119 wRC+ in 128 plate appearances with the Giants so far):

It’s no secret that the Giants have been receiving incredible production across their entire lineup. Their position players have posted a collective 113 wRC+ this season, a figure that ranks second in the majors among teams’ non-pitchers. But even in a lineup filled with players having above-average offensive seasons, Ruf stands out with his .279/.401/.544 slashline and 155 wRC+. That wRC+ ranks seventh in the majors among players with at least 250 plate appearances overall, sandwiched between Juan Soto (156) and Shohei Ohtani (154). That’s pretty phenomenal company, and it inspires two obvious questions. First, how did Ruf become one of the best hitters in baseball, at least this season? And, of course, how sustainable is this?

I will never not be fascinated by the fact that hitters actually produce negative value when swinging. In my most recent article outlining the struggles of Jarred Kelenic, I briefly discussed this idea. Even in a sea of hitters who are below-average when swinging, Kelenic stands out as being particularly bad when he takes a hack; he’s been worth roughly -6 runs per 100 swings so far this year. And as I noted, the hitters who do the best at limiting the damage on their swings tend to be baseball’s most productive hitters overall. From that research, I found an R-squared of 0.714 between a hitter’s run value when swinging and their seasonal wOBA.

That makes a ton of sense: Hitters who maximize their production on swings — that is, both limiting whiffs and making frequent loud contact — tend to be better hitters overall. But this also got me thinking about the reverse: How does taking pitches influence a hitter’s overall production? From the Kelenic research, I found only a moderate correlation between take value and seasonal wOBA, with an R of 0.422 and an R-squared of 0.178. That’s not to say that better “takers” aren’t better hitters; it just suggests that having extremely high-value takes doesn’t necessarily lend itself to having more success overall. For posterity’s sake, here’s the plot of 2021 hitters’ run value per 100 takes and their seasonal wOBAs. Players on both ends of the wOBA spectrum are highlighted just to demonstrate a few individual examples: 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 »

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 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 »

Brett Baty has a bright future, and he’s showing glimpses of why in his first full professional season. Just 21 years old, the left-handed-hitting third baseman is slashing .291/.378/.471 with 12 home runs in 378 plate appearances between High-A Brooklyn and Double-A Binghamton. Moreover, he’s doing so with a first-round pedigree. Baty was drafted 12th overall by the New York Mets in 2019 out of an Austin, Texas high school.

On paper, he’s a slugger. Ranked No. 2 on our updated Mets Top Prospects list, Baty was described by Eric Longenhagen prior to the season as having “light tower power.” His M.O. differs from that description.

“I like to say that I’m a hitter before the power, and the power is just going to come,” said the 6-foot-3, 210-pound Baty. “I’m just trying to hit the ball hard, wherever it’s pitched. I don’t want to get too pull-happy — try to hit pull-side home runs — so I’m up there thinking ‘line drive to left-center, line drive up the middle.’ Basically, I’m trying to stay within myself at the plate and hit balls hard, wherever they might land.”

Watching balls land over the fence is a thrill for any hitter, and that’s especially true for prospects looking to validate their first-round bona fides. But again, Baty shies away from the bopper label. Read the rest of this entry »

It’s already September, and maybe you’re still processing that fact. I’ll do you one better by pointing out that the Dodgers and Giants are about to play each other for the final time in the regular season. This is the earliest in the year that these rivals’ last series has occurred since way back in 1968, when Willie Mays and Don Drysdale were fixtures of the rivalry.

With Los Angeles and San Francisco tied atop the division and both teams on pace for 100 wins for the first time since 1962, I thought it prudent to break down what we might expect in this big weekend series.

The Series So Far

The Dodgers and Giants have split their 16 games so far (with San Francisco winning five of the last seven), featuring stellar pitching, unlikely heroes, home run robberies and blown saves. A four-game series in mid-July was full of drama, including Tyler Rogers giving up a walk-off homer to Will Smith, his second three-run outing against the Dodgers this season.

The very next night — actually the next two nights — it was Kenley Jansen who was handed a ninth-inning lead but walked off to a booing home crowd both times after giving up seven combined runs.

That’s just how this series has gone; no lead is safe from a disaster.

Corbin Burnes is laying waste to the National League, putting up numbers that can best be described as comical. A 34.6% strikeout rate? That’s closer territory. A 4.8% walk rate? That’s lower than Kyle Hendricks’ career mark. His 2.27 ERA might undersell how good he’s been; both his xERA (a Statcast ERA estimator) and FIP are in the ones (1.96 and 1.58, respectively).

You know about the cutter he leads with, which he described to David Laurila earlier this year. You know about the slider and sinker, the two pitches that complement his cutter. That trio took the league by storm last year, and he’s doubled down on cutters this year; he now throws the pitch roughly half the time.

Like an annoying hipster, though, I’ve moved on to the next cool Burnes thing that no one is talking about yet. The cutter? It’s fine, I guess (it’s the best cutter in baseball, but I’m doing a bit here, so bear with me). I’m here to talk to you about the curveball, a pitch that he threw less than 10% of the time before making it a staple this season.

If Burnes has one standout skill, it’s his ability to impart spin. Even when he was bad, he threw the highest-spinning four-seamer in the game, and his slider has always jumped out of his hand. It’s hardly a surprise that his curveball is cut from the same cloth. Spin data is fraught this year, what with the foreign substance crackdown and all, but since June 21, he’s thrown his curveball with a whopping 2,840 rpm, the 16th-best mark in the game (21st-best if you consider spin-to-velocity ratio instead).

What does that mean in English? It means that he has the raw stuff to generate eye-popping movement. He also throws the pitch in the low 80s, which means batters don’t have a ton of time to react. Put those two things together, and you can make MVP candidate Buster Posey look like a toddler learning how to walk:

The pitch is an absolute delight, and it’s also phenomenally effective. Batters have come up empty on half of their swings against it, the third-highest mark in the league (and 45% since June 21, so don’t go sticky-stuff-asterisking up this great pitch). As an added bonus, he’s seventh in baseball when it comes to batters not swinging at pitches in the zone. He throws it for a strike 49.3% of the time, which ranks seventh in the majors, and batters take it, doing his work for him. Can’t hit it when they swing at it, often take it when they should swing at it: what’s an opposing hitter to do but complain?
