If you don’t look too closely, it’s easy to see Brad Hand at the top of the ERA and WAR leaderboards for relievers and shrug. He’s an excellent reliever, of course; he hasn’t had an ERA above three since adding a slider after the 2015 season. When Cleveland traded Francisco Mejia for him (and Adam Cimber) last summer, they weren’t adding two generic middle relievers; Hand was the hottest commodity on the relief-pitching market for a reason.

There’s nothing too surprising about a good reliever continuing to be good. Hand struck out 35% of the batters he faced last year; he’s up to 39% this year, which is better but not obscenely so. If you don’t look at Hand’s batted ball data, in fact, you might think nothing has changed. The fact that I wrote that, though, means that you should look at his batted ball data; something jumps out immediately there. Take a look at this graph of Hand’s groundball rate by year:

What the… Brad Hand has the lowest GB% in baseball this year, and it’s the lowest by a lot. His 9.7% mark is less than half the next-lowest rate. The distance between Hand and second-place Jeffrey Springs is the same as that between Springs and 23rd-place Roenis Elias. That’s quite a change for a pitcher who had run a higher-than-average groundball rate the last three years.

The first thing to ask when seeing a split as extreme as this is “Is it April?” Now, while it’s not April, it’s still early in the season, particularly for a reliever. Hand has appeared in 16 games this year, so let’s take a look at his groundball rate over every 16-game stretch since 2016:

Yeah, okay, something’s up.

It’s amazing to write about baseball through the lens of a singular player like Mike Trout. The sheer totality of his excellence is fun in a way that just wouldn’t be true if you looked at all of his skills individually. Trout is an above-average outfielder, sure, but that isn’t all that fun by itself. He has great plate discipline — so too, though, does 2019 Jason Heyward, and he doesn’t spark the same kind of joy as Trout. No, the fun is that there’s basically no category you can come up with where Mike Trout isn’t good.

This got me to thinking: would it be fun to have a player who was like Trout, except not to quite the same degree? I don’t mean in the broad player value sense — in a way, every player in baseball is just a worse version of Trout. No, I mean someone who’s good at everything across the board in the same way that Trout is — just, a little less.

Trout hits for power, so our mystery player will need to hit for good (but sub-Troutian) power. Scratch both Joey Gallo and Jose Altuve from the list. They have to have an excellent eye at the plate and be judicious with their swings; sorry, Javier Baez, but the ride ends for you here. They need to be an above average baserunner, but not the best of the best — J.D. Martinez and Trea Turner both fall at this hurdle.

To work out this highly unscientific study, I started with stats from 2017-present for everyone who qualified for the batting title in at least one of the three years. This lets me cast a wide net without picking up someone whose prime isn’t happening now. First, I looked for players who were worse than Trout in a few categories: ISO, OBP, SLG, BsR/PA, BB%, and K%. (At this point in the search, I learned that Trout has a higher ISO than Aaron Judge, and I mean, wow.) Read the rest of this entry »

When a meteoroid strikes the top of the Earth’s atmosphere, it’s traveling at an unthinkable speed — something like 30 miles per second. Though it’s initially as cold as the void of space, the friction of striking the atmosphere creates intense heat. The thermal energy is sufficient to vaporize it, layer by layer. If the meteoroid survives long enough to strike the Earth’s surface as a meteorite, its outer layer will be blackened beyond recognition. I learned all this on Wikipedia today, because I wanted to understand what it must be like to face Tyler Glasnow.

Tyler Glasnow is a singular pitcher. He stands 6-foot-8, one of only three current major league pitchers that tall. He throws a 97.4 mph fastball. Among starters, only Noah Syndergaard throws harder. It’s not so much that Glasnow releases the ball tremendously high in the air; he’s a long strider, which lowers his release point. It’s more that there’s no one in baseball who throws quite like Glasnow throws — at extreme velocity, with extremely long levers, from a unique release point. Glasnow’s perceived velocity is second only to Jordan Hicks — his fastball explodes towards batters.

As if that weren’t enough, Glasnow’s curve has long been above-average. Want to know how long this has been the scouting report on Glasnow? Take a look at what Eric Longenhagen had to say about him before the 2017 season: “Glasnow’s scouting report has read the same way for the last four years. He throws hard, has touched 100 in the past (I have him maxing out at 97 this year) and spins one hell of a curveball — a potential plus-plus curve, in fact.”

The knock against Glasnow has always been control. In the minor leagues, he often ran double-digit walk rates, and when he got his first extended playing time in the majors in 2017 he walked 14.4% of the batters he faced. Glasnow was a project — and there was hope that his command would come. Here’s Longenhagen again: “That said, there are reasons for patience with the command. Glasnow’s velocity exploded in pro ball, and it’s not easy for someone to quickly learn how how to harness and command that kind of newfound arm speed — and even more difficult when the prospect in question is built like a giant whooping crane.” Read the rest of this entry »

Take a look at a 2019 WAR leaderboard and you’ll see some familiar names at the top. Cody Bellinger is having a whale of a season. Christian Yelich is hitting like Barry Bonds and is somehow second in the majors in baserunning runs as well. Mike Trout — well, you know Mike Trout. Look a little closer though, and you might notice something strange. There are four shortstops in the top 10 for WAR this year, and they’re not the usual suspects. Paul DeJong, Elvis Andrus, Jorge Polanco, and Javier Báez are all having great seasons so far, and if you had them as the four best shortstops in baseball this year, you’re a better prognosticator than I am.

Cast your eyes a little further down the board and you might see an interesting trend. Marcus Semien is 11th in WAR. Tim Anderson, Trevor Story, Xander Bogaerts, and Adalberto Mondesi are in the top 25, and Fernando Tatis Jr. isn’t far behind. Perennial stalwarts Andrelton Simmons, Corey Seager, and Carlos Correa are off to good starts. Shortstop, in fact, has produced more WAR than any other position this year.

Now, to some extent, that’s a referendum on how important shortstop is defensively. Only catcher has a higher positional adjustment than shortstop, and as a result only catchers have been worth more defensive runs this year. However, dismissing the prevalence of shortstops atop the WAR leaderboard as a defense-based illusion sells this current crop short. We could very well be looking at the best-hitting shortstop season of all time.

Let’s start at the very top with wRC+. This year’s shortstop class has produced a 107 wRC+ so far. That isn’t the actual best in baseball history, but it’s second only to 1874, and hoo boy are stats from 1874 weird. In that season, shortstops walked .9% of the time, struck out 1.2% of the time, and delivered a batting line of .305/.311/.372 in only 660 games. Let’s be reasonable here and throw out everything before the turn of the century. Cut those out, and the leaderboard looks like this:

2019 shortstops are on top, and it isn’t particularly close. Strip out everything pre-integration, and the recent rise of slugging shortstops jumps out even more:

Ask most baseball fans for the best shortstop-hitting season in history, and they’ll point to 2002. This was indeed a year of great shortstop hitters — Alex Rodriguez hit .300/.392/.623 on his way to a 10-WAR season, and Derek Jeter, Nomar Garciaparra, and Miguel Tejada all had sterling years. That’s all well and good — it was a top 10 season on the above leaderboard, after all — but 2002 also had 585 plate appearances of Neifi Perez’s .236/.260/.303 line, as well as a shockingly low-offense season from Rockies shortstop Juan Uribe, who hit .240/.286/.341 while playing half of his games at Coors.

This season has its fair share of laggards (Brandon Crawford is slugging .212), but it also has 16 shortstops with a batting line at or above league average. Freddy Galvis is hitting .297/.317/.485 and is the 14th-best-hitting shortstop this year. That 114 wRC+ would have been sixth-best in 2002. The depth of shortstop right now is simply stunning.

2018 wasn’t supposed to be the year of Juan Soto in Washington. It was supposed to be the year of Victor Robles. Robles, the consensus No. 1 outfield prospect in the Nats system and probably the No. 2 outfield prospect in all of baseball behind Ronald Acuña, was ready for the majors. Only a hyperextended elbow kept Robles from making an impact in the majors last year, but in abbreviated playing time in August and September, he looked like he was making up for lost time (.288/.348/.525, 131 wRC+).

Robles’ 2019 hasn’t been quite as impressive, but you can see in his performance why he’s such an exciting talent. Even while running a 30.5% strikeout rate and walking only 4.8% of the time, Robles has put up a league-average batting line (.265/.308/.480, 102 wRC+). Watch Robles play, and you can immediately see what the hype is about. He’s electric both at the plate and in the field. With all that said, I’m not here today to talk to you about Robles’ tremendous potential or his jaw-dropping athleticism. I’m here for the bunts.

Victor Robles leads the major leagues in bunt singles this year (he’s actually tied for the lead with teammate Adam Eaton). It’s a good thing, too, because he’s also first in bunts (fair balls that were bunted — it’s hard to get a good count of foul bunt attempts). If that seems weird to you, you’re not alone. We’re talking about a guy with non-negligible power — the FanGraphs prospect team graded him at 50 raw power this offseason. He has four home runs so far this year, and he ran a .157 ISO in the minor leagues, which isn’t Joey Gallo level or anything, but is certainly not poor.

Take a look at this list of players with the most bunts per plate appearance since 2017, Robles’ first playing time in the majors. I liberally filtered out pitchers and people with less playing time than Robles:

Robles sticks out like a sore thumb on this list. Magneuris Sierra literally had a zero ISO in 64 plate appearances in 2017. He’s never hit more than four home runs in a season, minors or majors. Delino DeShields hit six home runs in 440 plate appearances in the bigs — once. Robles has four this year already. Depth Charts projects him for another 11 over the balance of the year. Heck, he had three homers in 66 PA last year when he was called up. Maybe he’s not a power hitter, but he’s certainly not a slap hitter either. What’s up with the love for bunts?

If you know one thing about Kolten Wong, you probably know that he’s a great defender. Honestly, great defender might be underselling it. Since 2014, his first full year in the bigs, he’s third in Defensive Runs Saved at second base. Maybe UZR is more your speed? Wong is third there, too. This isn’t some trick of innings played, either — he’s fourth in UZR/150 among qualifiers. He hasn’t won a Gold Glove yet, but it’s not because he doesn’t deserve it.

If you know Kolten Wong for a second thing, you probably know him for the endless flashes of potential, the bumpy road he’s followed throughout his major league career. In 2013, when he’d barely had a cup of coffee in the regular season, he got picked off of first base to end a World Series game. After two average-ish seasons in the majors, he found himself playing the outfield (?!) so that the team could squeeze more at-bats out of… um… Matt Adams? Brandon Moss? Greg Garcia? Mike Matheny-run teams had some interesting substitution patterns, let me tell you.

In any case, whatever you know about Kolten Wong, elite plate discipline probably isn’t on your list. After all, Wong is on the field for defense. Take a look at his yearly wRC+ numbers, starting with his first full year: 90, 96, 85, 107, 98. Those numbers are totally acceptable for a premium defender (Wong’s career wRC+ bests Andrelton Simmons’), but they also lead to batting at the bottom of the lineup more often than not.

Here’s the thing, though: Wong is certifiably great at controlling walks and strikeouts. It’s not just a 2019 thing, though it’s certainly been the case so far in 2019. Take a look at the list of qualified batters with more walks than strikeouts this year:

When I was a kid, my dad taught me about baseball whenever he got a chance. A lot of these lessons were just meaningless baseball truisms: always hit to the right side of second base when there’s a runner on, the best count to steal on is 2-0, catchers are never lefties. Most of these sayings stuck in my brain without ever registering on a conscious level, but one of them fascinated me the moment I heard it. “Throw fastballs when the batter is ahead in the count and breaking balls when he’s behind.” It is known. I’ve pondered the reasoning and factuality of that rule of thumb ever since.

At the most basic level, I totally understand the thinking going on. Fastballs are easier to locate for a strike, and when you’re behind in the count you can ill afford to throw a pitch for a ball. It’s not just that, either. When a batter is down in the count, they need to be much more proactive about swinging at any pitch in the strike zone. If you throw a 1-2 breaking ball that starts out looking like a strike, the batter needs to swing. Throw the same pitch on 2-0, however, and even if it looks like a strike at the start, the batter might not swing — they could be looking for a specific location rather than defending the entire plate.

Go one level higher, however, and things get a lot more confusing. Pitchers throw fastballs when behind in the count, and batters know that pitchers throw fastballs in hitters’ counts. If a hitter knows you’re going to throw a certain type of pitch, that makes their job a lot easier. One of the hardest parts of being a major league batter is that you have to determine how a pitch is going to break after leaving a pitcher’s hand almost instantaneously. Curveballs and fastballs might start at the same place, but they end up in different areas entirely. Take this deception out of the equation, and hitting gets quite a bit easier.

That’s only one level up, though. We can go further. Pitchers know that hitters know that pitchers throw fastballs when behind in the count. If you’re getting a Princess Bride vibe here, you’re not alone. This is a complex issue. What batters expect pitchers to do plays a role in what pitchers should do, and vice versa. There’s an entire field of economics, game theory, devoted to solving this problem. Maybe you saw the movie about it, where Russell Crowe inexplicably writes on every glass surface he can find.

Let’s leave that all aside for now, though. Whatever the theoretical equilibrium is, pitchers do indeed lean away from breaking balls when behind in the count. In 2018, for example, pitchers threw sliders and curveballs 18.8% of the time when behind in the count, versus 27.5% of the time when they were ahead. That’s major league baseball as a whole, though. Collin McHugh has gone to a breaking ball 58% of the time when down in the count. Gerrit Cole is above 40%, and Robbie Ray isn’t far behind him.

Trevor Bauer, on the other hand, seems to have listened to my dad’s advice. Bauer has thrown 139 pitches while behind in the count this year. He’s gone to a breaking ball exactly twice. He’s on pace to set a career low for breaking balls while down in the count, and it’s not even particularly close. In 2016, Bauer fired only 43 breaking balls out of 878 pitches he threw while behind in the count. That was a preposterously low 4.9%, and still triple the rate he’s put up this year so far.

It’s still April, so it may be premature to talk about the year’s most extreme events. If a home run was hit on a high pitch, there will likely be a higher pitch that gets hit for a home run later on. Think an umpire called a perfect pitch a ball? We’ve got plenty more time for an even better pitch to be missed. However, I think we may have already seen the best pitch frame of the year.

I don’t mean the pitch furthest outside the strike zone that gets called a strike — there’s still plenty of time for that to change. I’m talking about full dedication to the craft of pitch framing. Francisco Cervelli sold a pitch against the Cubs not just with his glove and his positioning, but with his whole being. You’ll probably see worse pitches sold for strikes this year. Heck, you might see Cervelli get more egregious calls than this. You won’t see better framing, though — I can pretty much guarantee it. Read the rest of this entry »

If you want to paint with an extremely broad brush, you can think of the last twenty years of analytical advances in baseball as waves, alternately benefiting hitters and pitchers. First came the Moneyball years, when sabermetric advances brought offense into the game. It wasn’t just that teams started playing more beefy guys who could hit for power and take a walk. They also encouraged their existing players to be more patient — that’s how you got the iconic four-hour Yankees-Red Sox games of the mid-2000s, in which both teams seemed to make a personal challenge out of who could take more pitches. This coincided with the beginning of the end of the sacrifice bunt, yet another boost to offense.

If it first seemed like every analytical advance increased offense, however, the tables quickly turned. First the Rays realized that newly offense-minded front offices were undervaluing defense. Then they turned to infield shifts. Before long, the Pirates were using data to optimize pitch selection and every team was hunting high and low for pitch framing. If the early 2000s were all about using math to find better ways to hit, 2008 to 2014 was about using data to strangle offense from every angle.

Things have started moving more quickly since then. Batters reacted by trying to lift the ball more, helped out by a livelier baseball. Pitchers tried throwing higher in the zone to counter that, and at the same time teams started working with pitchers to tailor arsenals to their innate spin rates and pitch shapes. It’s not stopping here — batters are going to work to counter pitchers’ new arsenals, and defenses are going to work to find new and better shifts.

For all this back and forth though, I think that the long game favors pitching. The reason is that, to my mind, batting is a game of picking on weaknesses. Teams don’t get their offense against the aces and the tough part of the bullpen, or in lefty-lefty matchups. They pick on tiring pitchers, righties pitching to lefties, or relievers pitching their third game in three days. It’s always been this way — offense spikes in expansion years when the pitching pool gets diluted, and the times-through-the-order penalty has always existed.

If that’s where offense has always been generated, however, then batters are in trouble. Pitching staffs across baseball are shoring up weak points like never before, and there’s not much offenses can do about it aside from just hit better. It’s still April, but it’s almost a guarantee that two pitching trends are going to reach all-time extremes this year. You’ve probably heard of the first one: starters will face batting orders for a third or fourth time less than ever before. The second one is more subtle, but it’s affecting offense just the same. So far in 2019, batters have faced opposite-handed pitching only 51% of the time, a record low.

Let’s handle the times through the order trend first. The effect isn’t novel — I learned about it from The Book, but the general concept has existed much longer than that. Ted Williams talked about it in The Science of Hitting, and it’s not some deep secret. The more looks a batter gets at a pitcher, the better he sees the pitches. It’s not clear whether pitcher fatigue adds to the penalty, but either way it’s not a small effect. In 2018, starting pitchers allowed a .304 wOBA the first time through the order and a .336 wOBA the third time through. That 32-point wOBA swing is about the same as the difference between the 2018 Yankees offense and the 2018 Royals offense. It’s a big deal, in other words. Read the rest of this entry »

Being a fan of a rebuilding team is a tricky line to walk. You want the players to do well, obviously — you’re watching them every day, after all, and it’s only human to root for what you’re watching. At the same time, if they do too well, they’re probably getting traded — how much mental energy should you invest in a player who won’t be on your team in two months? Did that reliever you like find another gear? Cool, enjoy the two lower-level prospects the team will get back for him in a month. Rooting for a past-their-prime star? Well, if they have a good stretch, the team might ship the one face you remember from the good old days out for some salary relief.

There’s one great joy in watching a team that’s in the middle of a rebuild. Whether by accident or design, teams don’t end up trying to retool if they have a ton of solid major league players, which means there’s a playing time void that gets filled by whoever’s available. Minor league free agents and past-their-prime vets? Step right up. Lifetime minor leaguers looking for their first real chance? Someone needs to play third base, so grab a glove. When one of those lottery tickets hits, that feeling makes up for a lot of the bad parts of rebuilding. Here’s a player who has always wanted a chance, and your team gave it to him. If he’s young, he might even be around when the team’s good again, and you, the fan, were there at the beginning. All of this is a roundabout way of saying: Niko Goodrum might be awesome, and the Tigers gave him a chance.

If you haven’t heard of Niko Goodrum before, I can’t blame you. He got a cup of coffee with the Twins in 2017 before signing with the Tigers after the Twins released him, and he delivered a solid if uninspiring 2018 (103 wRC+ in 492 PA, 1.1 WAR) while playing across the diamond. He’s been excellent to start this year, putting up a 132 wRC+ with nearly as many walks as strikeouts while batting cleanup and playing both centerfield and first base. Now you, the sophisticated FanGraphs reader, are no dummy. You know that a 132 wRC+ a few weeks into the season isn’t all that outrageous. It’s above average, sure, but no one’s going to lose their mind over it. What makes me so sure Niko Goodrum is amazing all of the sudden? Read the rest of this entry »
