One of the ways that the baseball of yesteryear was different from baseball today was the importance of batting average. With a pitching philosophy that envisioned lots and lots of balls being hit into play and no gauntlet of modern relief pitchers to face, far more at-bats ended with a ball being handled by a defensive player. In 2019, 63% of plate appearances ended with a ball being hit into play. In 1919, that figure was 81%. With half as many fieldable balls, it’s hardly a shock that league batting averages have declined. The effect would be even larger, too, but batting average on balls hit into play was higher in 2019 (.298) than in 1919 (.282).

Hitting .400 was never an easy feat, but it wasn’t some wild, once-in-a-lifetime occurrence when it did happen. The .400 mark has been eclipsed 34 times in major league history, give or take (the number varies depending on just what you consider a major league team in the wild world of 1870s baseball). Ted Williams hit .406 in 1941 and that was it, the last time a major leaguer hit .400 over a season. It’s more than just the lower league batting averages. Baseball’s .252 batting average in 2019 was still higher than in 17 seasons before 1941. Baseball has trended in a more competitive direction and as a league becomes more competitive, you generally expect the differences between players to shrink. That’s true for batting average, too. Just look at the simplest measure of dispersion, standard deviation:

The standard deviation has gotten smaller as time has progressed. Using this simple method, Ted Williams’s .406 in 1941 was 4.46 standard deviations better than the mean batting average of .262 (z-score). A z-score of 4.46 in 2019 only represents a .370 batting average. Nobody’s hit that mark recently, either, but .370 certainly doesn’t feel like anywhere near the same hurdle.

Since it’s the obvious next question, here are the best batting averages by Z-Score. Again, there are more robust ways to look at this, but we’re scrawling on envelope-backs, not landing astronauts on the moon:

Earlier today, Paul Sporer took you through baseball’s 16th-to-30th ranked rotations. Now, we get to the good stuff.

What is a starting pitcher? While baseball’s rules have been relatively stable throughout the game’s history, being a starter in 2020 means something very different than it did in 1870, 1920, or even 1970. A starting pitcher in the 1800s was frequently the pitcher in any given game. When Hall of Fame pitcher (and later, Twitter superstar), Old Hoss Radbourn pitched for the 1884 Providence Grays, he started 75 of the team’s 114 games, completing 73 of them.

Being a starter meant something else in the early 20th century. They were still workhorses expected to finish a large percentage of their games, but they were part of a pitching staff, not lone wolves. Jack Chesbro was the last 50-game starter, in 1904. Four-man rotations became the standard and league leaders in games-started ranged from the high 30s to the low 40s. The only exception was one last surge in the early 70s from rubber-armed knuckleballers Wilbur Wood and Phil Niekro. The four-man rotation then became a five-man affair, and it’s now been 33 years since a pitcher started 40 games (Charlie Hough, 1987) and 40 years since one threw 300 innings (Steve Carlton, 1980).

A report Tuesday from MLB.com’s Mark Feinsand indicates that Yasiel Puig will sign a one-year contract with the Atlanta Braves. The 29-year-old Puig hit .267/.327/.458 with 24 home runs for a 101 wRC+ and 1.2 WAR while playing for the Reds and Indians in 2019. The former Rookie of the Year runner-up spent most of last season in Cincinnati before heading to outfield-deficient Cleveland as part of the three-way trade that sent Trevor Bauer to Cincinnati and Taylor Trammell to San Diego. The exact financial terms of the deal are not yet available, but it’s unlikely that Puig’s one-year contract is for an exorbitant amount of cash from the team’s point of view.

From a pure “how good is Puig?” standpoint, completely divorced from context, this signing is an underwhelming one. Puig hit the market unencumbered by the possible loss of a draft pick upon signing (he was ineligible to receive a qualifying offer because of the trade), but even still, his free agency garnered a tepid reception this winter. Now, this offseason’s free agent market featured a lot more action than other recent ones, but that was driven by elite free agents such as Gerrit Cole and Anthony Rendon. Teams were still generally uninterested in first basemen and corner outfielders, with few getting multi-year deals and only José Abreu and Nick Castellanos getting more than $20 million guaranteed. Puig drew some interest, but nobody seemed all-in on bringing him in before spring training or when transactions were recently unfrozen. Read the rest of this entry »

On Monday, Jay Jaffe kicked off our positional power rankings series by evaluating the league’s first basemen. If you need a refresher on the series, Meg Rowley wrote a handy explainer. Today, we stay on the infield and turn our attention to second base.

Second base has become a decidedly unsexy position. Teams are more willing than ever to keep players at shortstop, leaving the keystone increasingly populated by the guys with weak arms, not enough glove for short, or not enough bat for third base. Throughout history, shortstops have generally hit worse than second basemen, which makes sense given that short is the tougher defensive position. But in 2018, after years of slowly gaining ground, shortstops outhit second basemen, with a 97 wRC+ vs. 95 at second; in 2019, they did it again (100 vs. 96).

It hasn’t helped the position that there’s been a talent drain. Chase Utley, Ben Zobrist, Ian Kinsler, and Brandon Phillips are all gone, Robinson Canó, Brian Dozier, and Jason Kipnis are nearly so, and it’s an open question whether Dustin Pedroia plays again. Only José Altuve is all that is left standing of the elite second basemen from the 2010s. Meanwhile, there are only seven second basemen with a future value of 50 or better on THE BOARD, compared to nine at third base and 14 at shortstop. Inevitably, some of the shortstops will end up as second basemen, but that’s kind of the point; the shortstops that shift will likely be the ones who didn’t make the cut at short. Players like Gavin Lux and Nick Madrigal will provide new blood, but they’re likely at least three or four years away from their peak years. Read the rest of this entry »

One of the defining features of late 1990s baseball was the battle between three young, superstar shortstops: Alex Rodriguez of the Seattle Mariners, Derek Jeter of the New York Yankees, and Nomar Garciaparra of the Boston Red Sox. There were the occasional interlopers, such as Barry Larkin in his late-career surge and Jay Bell with the Diamondbacks in the midst of his second wind, but A-Rod, Jeter, and Garciaparra were the big three at the top of the leaderboards. The debate surrounding these three shortstops was very much in the public eye, with the trio at the top of the sport in terms of both name recognition and performance.

We’ve been blessed with a flurry of phenom shortstops since then, but having three multi-talented players at the position who were also elite offensive performers was rather novel at the time. Cal Ripken Jr., Alan Trammell, and Robin Yount came the closest in living memory, but that fight was short-lived as Yount eventually moved to the outfield. To find another three this good, you’d have to jump back 60 years to the days of Lou Boudreau, Luke Appling, and Arky Vaughan. Read the rest of this entry »

Yesterday, I posted my 10 favorite breakout candidates for our abbreviated 2020 season. Now it’s time for that piece’s inevitably less-optimistic companion, the breakdowns.

As with the breakouts, precisely defining a breakdown in exact statistical terms is difficult and, I feel, counterproductive. Sometimes it’s a guy with a few dangerous leading indicators; other times, it’s a player who has already seemingly fallen off the cliff and it’s whether he can catch the ledge. Occasionally, a player reaches an age when decline is nearly inevitable; time eventually defeats all of its opponents after all.

With all that in mind, here are my “favorite” 10 breakdown selections for 2020’s 60-game sprint.

Justin Verlander, Houston Astros

Don’t get me wrong, I still think Justin Verlander is a terrific pitcher. But he’s at an age when pitchers can decline very quickly and he’s recovering from a significant groin injury. ZiPS is still convinced he’s an easy ace, but those low-percentile projections have gotten a bit scarier. Verlander’s projection for 2020 is quite close to his 2019, but the differences at the bottom are stark; ZiPS projects an 14% chance of Verlander having an ERA+ under 80; when re-projecting 2019 with a 60-game season, that number was only 5%. There’s no methodology change that accounts for these differences. As breakdowns go, this is a mild one, but it’s significant given Houston’s increased reliance on Verlander without Gerrit Cole around. Read the rest of this entry »

Predicting breakout candidates is one of the hardest and most frustrating tasks for anyone who tries their hand at baseball soothsaying. By its very nature, a breakout (or breakdown) projection is a low probability event. If it wasn’t, it would be the basic projection! Your big hits will be next to some embarrassing mistakes. For example, if I were of a mind to gloat about having said in this 2018 piece for ESPN that Christian Yelich had a peak Joey Votto/Will Clark season in him, I couldn’t get around the fact that the player listed right after Yelich was Danny Salazar, who has appeared in one game since that article ran.

So what constitutes a breakout season? Is it a player making a significant change in one aspect of their game? A bounce-back season? Is a top prospect showing improvement a breakout? Or is it a sudden step forward along broad lines? I’d argue that it’s any and all of these things. I used to try to statistically define a breakout season, but in the end, I found no purely mathematical estimation that was satisfactory. As I’ve written this piece over the years, I’ve gone with a more abstract definition: when a player, capable of contributing to a playoff contender, is able to fundamentally change what we think of them.

Predicting breakouts and breakdowns for 2020 is even tougher than usual thanks to the 60-game season, which will complicate knowing if I’m right even if it is somehow miraculously played to completion. But it’s part of the job, so let’s get to the bet-making instead of the bet-hedging. Here are my 10 favorite breakout picks for 2020.

Eloy Jiménez, Chicago White Sox

Eloy Jiménez had a vaguely disappointing rookie year in 2020, with a .513 slugging percentage in a pinball season not enough to balance out the .315 on-base percentage and mediocre defense. What keeps me a believer is that he was a more well-rounded hitter in the minors than he’s displayed in the majors and it’s way too soon to peg him as a low-OBP slugger. It was encouraging that his plate discipline numbers improved over the course of 2019, and ZiPS thinks his second-half .337 BABIP is closer to his real number than his .275 over the season’s early months.

I don’t think a year similar to Yordan Alvarez’s .313/.412/.655 2019 would be all that shocking. Neither does ZiPS; in a 600 PA season, it put his 90th percentile home run total at 54.

I kind of wanted to put Nomar Mazara here as a tandem, but I resolved to stop picking him after doing so for three consecutive seasons and whiffing each time. A breakout is still a possibility for Mazara, but if I pick him for a decade and he finally does break out, I’d just be the blind squirrel finding the nut.

Adrian Houser, Milwaukee Brewers

You’d be excused for not getting excited about Adrian Houser as a prospect; he was never especially enthralling in the minors. What was exciting, however, was Houser’s two-seamer/sinker, which he used to great effect in 2019. Pitch-classification algorithms can have issues with a pitcher like Houser, but while he upped his grounder game considerably last season — useful for a right-handed pitcher given Miller Park’s history as a haven for left-handed sluggers — he did it while avoiding the somewhat dated approach of simply constantly throwing hard and down.

Houser did have considerable splits last year depending on his role, with a 4.57 ERA as a starter compared to 1.47 in relief. But in a rotation that seems overstuffed with third and fourth starters, Houser’s upside is interesting.

Dinelson Lamet, San Diego Padres

One thing people forget about Dinelson Lamet is how little experience he actually has as a pitcher, with only 500 professional innings under his belt. I think there’s a good chance that if not for the Tommy John surgery, he’d be a legitimate ace right now for the Padres; his change was a work in progress at the time. Lamet has been 16 runs below-average with his mid-to-upper 90s fastball — which came back faster post-surgery — but I don’t think this is a case of Nathan Eovaldi, a pitcher who had trouble turning his velocity into outs. Lamet just hasn’t the time to refine his potent fastball-slider combination yet.

Luis Urías, Milwaukee Brewers

It strikes me as odd that in some circles Luis Urías is already thought a bust despite just turning 23. After sitting out the spring with a recovering from surgery on a broken hamate bone, Urías’ poor injury luck has continued; he tested positive for COVID-19 prior to the Brewers’ intake procedure for training camp. His case was reported to be asymptomatic and while we have little practical evidence of how cases like that will affect elite athletes, Craig Counsell appeared optimistic about Urías’ chances of rejoining the team in fairly short order. Urías had a disappointing stint in the majors in 2019, but even taking a huge chunk out of his .315/.398/.600 Triple-A effort due to the league offense and the level, there’s strong evidence that his baseline is well above his .223/.329/.326 major league line last year.

Victor Robles, Washington Nationals

It seems a little weird with the benefit of hindsight, but Victor Robles was always supposed to be the new hotness before Juan Soto exploded onto the roster in 2018. Robles isn’t going to catch up to Soto any time soon — or likely ever — but he showed signs of being a fairly complete hitter as a prospect and his defense in center field has been about as good as advertised. His main problem remains that he makes very soft contact, especially on groundballs, and I think his tendency to be overaggressive on the first pitch and top a soft grounder is hurting him here; he just doesn’t have the contact skills of a David Fletcher. Victor Robles will never hit for power like a Joey Gallo, but better pitch selection would give him a shot at retaining his 2019 home run bump. Too much of his current plate discipline comes from simply being willing to take a hit by a pitch.

Dansby Swanson, Atlanta Braves

Poor Dansby Swanson is at risk of becoming the new Gregg Jefferies, a player who is always measured versus our lofty initial expectations, found wanting, and ends up underrated by “only” being a B+ player in the majors. Swanson hit the ball harder in 2020 than he ever had before in the majors, with his barrel rate more than doubling his 2017 and ’18 numbers and his weak contact hits dropping considerably. It didn’t show up in his overall stats, but ZiPS “thought” he should actually have been a .492 slugger instead of the .422 mark he posted. zSLG isn’t an outlier, either; Statcast’s xSLG had Swanson at .480.

Dylan Bundy, Los Angeles Angels

My working theory on Dylan Bundy is that he needed a change of scenery more than practically any pitcher in the majors, both figuratively in terms of coaching and literally in terms of a park better configured to contain his mistakes. Bundy came out of high school nearly a decade ago as a hard thrower, a pitcher who regularly hit the high-90s and was clocked at 100 as an amateur. Years of injuries killed off the fastball, but Bundy continued to pitch as if he was still that pitcher, aggressively challenging hitters with a 91-92 mph four-seamer. That doesn’t actually work against major league hitters; for his career, he’s allowed a .542 SLG on four-seamers, including a .574 in 2018 and a .642 in 2019.

Bundy has to reinvent himself the way Frank Tanana did after his injury. There were signs of progress at times in 2019, with Bundy trying to change speeds more often. I still think there’s upside here if the Angels convince Bundy that his comps fall along the lines of Doug Fister, not Randy Johnson.

Byron Buxton, Minnesota Twins

Byron Buxton thrived last season when the Twins finally did what they’d resisted doing for years: sticking him in the lineup, letting him play, and not panicking every time he had a bad week. ZiPS gives Buxton a 10% chance at a 130 OPS+, enough that it would make him a superstar when combined with his defense. The shoulder is a concern, but he’s also had the luxury of more time to recover because of the pandemic’s long layoff.

Mitch Keller, Pittsburgh Pirates

I can’t think of a scenario in which Mitch Keller’s .475 BABIP in 2019 represents an actual ability. I’m not convinced that Mitch Webster, coming out of retirement and converted to pitching, would allow a .475 BABIP. Historically, hitters being dragooned as pitchers have a BABIP allowed in the .330 range, which I think sets a soft ceiling of minimal pitching competence. But it was such a wacky number that even ZiPS is having trouble coping and I’d take the under on the .328 projection, even with Keller having similar issues in the minors, though not to the same extreme. Like Lamet above and my eternal example, Kevin Gausman, I think Keller really needs an offspeed pitch he can count on, but the talent is there. It’s hard to strike out 12 batters a game and have no idea what you’re doing.

Tyler Anderson, San Francisco Giants

There’s a chance that this is personal bias since his windup always gives me nightmares in MLB: The Show, but Tyler Anderson was always on the verge of breaking out as command-type pitcher in Coors and with a better outfield defense and a friendly park in San Francisco, I think he could have a Kirk Rueter-type run of success. And yes, I know he’s more of a strikeout pitcher than Rueter — the comp isn’t perfect. Having the extra time to recover from major knee surgery will be helpful, I feel.

These are my breakout candidates. Next, I’ll reveal the sad side of the coin: the breakdowns.
