Bonus Intentional Walk Math: The Big Bang Theory

Yesterday, I wrote about the intentional walk heard ‘round the world. It was mostly reflex, really. When someone issues a strange intentional walk, I can’t help but dig through the numbers. But this one, I was quite sure from the start, was bad. The math was just a way of rubbernecking, staring at a baseball accident from across the highway and saying “Wow, I wonder how that happened?”

But in doing so, I didn’t engage Joe Maddon on his weird, hipster-glass-wearing turf. Maddon didn’t say he was trying to minimize run expectancy (though he should have been). He didn’t say he was trying to maximize his team’s chances of winning the game (though he should have been). He said he was trying to “avoid the big blow,” or prevent a big inning in other words.

Bad news, Joe! Using the same simulation I used to estimate run and win expectations, I can work out the chances of a “big blow” for some arbitrary definition of big. Take my initial simulation. I estimated that the Rangers stood to score roughly 1.75 more runs in the inning when Corey Seager came to the plate, before any intentional walk shenanigans. We aren’t limited to looking at that in terms of average runs, though. It can also be expressed as some likelihood of scoring zero runs, one run, two runs, etc:

Run Matrix, Pre-Seager Walk
Runs Likelihood
0 24.7%
1 30.2%
2 16.5%
3 11.3%
4 10.3%
5 4.4%
6+ 2.6%

Don’t Intentionally Walk Anyone With the Bases Loaded

You had to know this one was coming. The moment needs no introduction; let’s just start with a clip:

Intentional walk. Bases loaded. Mike Trout staring homeward in disbelief:

Was this a solid baseball decision by the numbers? No. No, it was not. I don’t really have to do the math to tell you that. But doing the math is what we do here at FanGraphs, so just to be certain, and also just for the sake of doing it, I ran through the details. You don’t have to read this article to learn whether it was a good choice or not. I’m telling you that part right up front – it wasn’t. Read the rest of this entry »


Curb Your Kwanthusiasm (But Just a Little Bit)

© Jay Biggerstaff-USA TODAY Sports

Welcome to KwanGraphs, your source for everything… wait, no, that’s not right. Welcome to FanKwan, your … no, still not it. This part is definitely true, though: today I’m here to talk about Steven Kwan, the Guardians phenom who swung for our hearts and didn’t miss. He was our No. 57 prospect heading into the season, and ZiPS concurred, calling him its No. 62 prospect. He’s been better than that so far — a top 10 hitter in baseball, more or less. Can he keep it going? Will he bat .330 with more walks than strikeouts? I crunched data and watched film to come up with some educated speculation.

Let’s start with the great news: Kwan’s phenomenal bat control is as real as it gets. He’s swung and missed either one or two times (and hey, good news for pedants everywhere, I’ve even thrown in a special postscript at the end of this post so everyone can whinge about foul tips in the comments) in his major league career so far, which is obviously great. Even better, this isn’t something new. In 2021, he was the best contact hitter in the minors, bar none.

Over 1,388 pitches I captured, Kwan swung 551 times. He swung and missed 39 times, and had another seven foul tips. That’s a swinging strike rate of either 2.8% or 3.3% depending on your definition, both of which are otherworldly. The contact rate is no joke, either: he made contact on more than 90% of his swings, which led the high minors and would have placed him in a dead heat with David Fletcher for best in the big leagues.

Jesús Luzardo Has Risen

Richard Mackson-USA TODAY Sports

Three days ago, Jesús Luzardo was a fun bounceback candidate. As a minor leaguer, he was one of the best prospects in the game, with an explosive fastball, a spectacular array of secondaries, and plus command. In his first two seasons of big league experience, that continued; he missed bats, walked only 6.8% of his opponents, and posted an ERA in the upper threes. But in 2021, his command collapsed, and with it his untouchable status in Oakland. In the midst of a 6.61 ERA season with an 11% walk rate, the A’s shipped him off to Miami in exchange for Starling Marte.

It’s not three days ago anymore. Now, after a dominant start, I’m considering a different question: is Luzardo Miami’s best pitcher? Is he one of the best pitchers in baseball, full stop? That’s probably hyperbole, but again: Luzardo was one of the best pitching prospects in baseball only a handful of years ago. Let’s give his remarkable turnaround the consideration it deserves, and see if we can figure out what changes he’s made to unlock this new level of performance while we’re at it.

First things first: has Luzardo made any changes to his delivery? To figure this out with my remedial understanding of pitching mechanics, I watched one fastball from his 2021 season and one fastball from his 2022 debut over and over (and over and over and over) again. Here are the clips in question. First, a called strike last April:

Next, a foul tip from Tuesday:

I’m hardly an expert here, but I noticed several differences. First, he’s more to the third-base side of the rubber. Second, at the peak of his lead leg’s lift, his glove position is meaningfully higher. Take a look at the two side-by-side and it’s somewhat obvious, even if the different aspect angles from the two broadcasts keep you from making a straight comparison:

Drew Rasmussen Made Sweeping Changes to His Slider

© Kim Klement-USA TODAY Sports

Drew Rasmussen was a Rays success story last year. A key part of the trade that sent Willy Adames to Milwaukee, Rasmussen profiled as a plus reliever. But after initially serving as a multi-inning bullpen arm, Tampa Bay slotted him into the rotation for the last two months of the season, and he delivered 37 innings of 1.46 ERA, 2.76 FIP excellence. Sure, it was over 4.5 innings per start, and the peripherals weren’t pretty, but quality over quantity has always been a deal the Rays will take, and you certainly can’t argue with his run prevention.

Rasmussen did it despite what could charitably be described as a predictable arsenal. He threw his fastball 65% of the time and his slider another 30% of the time. If we’re being honest, it was more like 1.5 pitches — his fastball did a lot of the heavy lifting, and the slider picked up the pieces. It’s one of those spin-and-speed four-seamers that are all the rage these days. Rasmussen didn’t always locate it well, but simply put, it’s a hard pitch to hit.

He paired that fastball with a slider that featured two-plane action. It wasn’t a big movement pitch; it had drop and arm-side run in roughly equal proportion, but its main standout quality was that it was an offspeed pitch when hitters were setting up for 98 mph at the letters. If you’re trying to cover a high fastball, particularly one that struck you out last at-bat like this:

Then it’s hard to adjust to a slow and low pitch like this:

When you look at it that way, it’s a pretty good pitch. And hey, by some metrics, it was: hitters had a lot of trouble squaring it up, mustering a woeful .226 wOBA on contact (and a 41% hard-hit rate). On the other hand, it hardly missed any bats; Rasmussen was in the bottom 10% of baseball for swinging strike rate and bottom 15% for CSW rate. Eno Sarris wrote about the pitch in the playoffs and came away similarly unsure of its efficacy. Read the rest of this entry »


J.P. Crawford and the Mariners are a Perfect Match

© Joe Camporeale-USA TODAY Sports

There are so many good young shortstops in baseball these days that it’s easy to lose track. The oldest starter in the top 10 of our positional power rankings is Xander Bogaerts, and he hasn’t turned 30 yet. Eighteen of the top 20 shortstops are under 30. It can feel like every team has one of these guys. But that doesn’t mean they’re not valuable, and the Mariners clearly agree: they recently agreed to a contract extension with J.P. Crawford that will keep him in the Pacific Northwest through the 2026 season.

Crawford is, for lack of a better way to put it, an in-between Mariner. The team’s old guard – Félix Hernández and Kyle Seager, for example – is gone. The new guard – Jarred Kelenic, Julio Rodríguez, Logan Gilbert, et al. – are breaking in now. But Crawford debuted for Seattle in 2019, and saw his first major league action in 2017. He would have reached free agency after the 2024 season, awkwardly in the middle of what the Mariners hope will be their new core’s best years.

The solution seemed obvious, and the deal the two sides worked out fits the mold almost perfectly. The five-year, $51 million pact is straightforward; no options on either side, no escalators, and no buyouts. It will pay him $10 million in each of the first four seasons and $11 million in the last year. Read the rest of this entry »


José Ramírez, Face of the Guardians Franchise, Is Sticking Around

Jay Biggerstaff-USA TODAY Sports

José Ramírez is subtly bending the fabric of space and time. It’s the only way I can explain it. How else can you square the particular details of his hitting prowess? He’s impossibly quick to the ball, creating consistent loud contact. That should require a wild swing, but it doesn’t. He’s one of the best contact hitters in baseball. He has one of the best approaches in the game; sometimes it seems like he knows what’s coming before the pitcher throws it. He’s one of the best defenders in the game. It all feels vaguely magical.

Until today, he was also the most underpaid star in baseball. A five-year, $26 million extension he signed before the 2017 season (with two team options for another $26 million) immediately preceded his ascent to one of the best players in the game. That’s no longer true; today, he more than tripled his career guaranteed earnings by agreeing to a five-year, $124 million extension with the Guardians.

This deal, which starts after the 2023 season, should keep Ramírez in Cleveland for the rest of his peak, and quite possibly the rest of his career. For fans of a franchise that had seen its home-grown stars leave quite a bit of late, it’s a welcome turn of events. For Ramírez, it’s financial and — thanks to a no-trade clause — workplace stability.

I know this article is about a contract, but I can’t help it: I just want to talk about how great Ramírez is. I wasn’t exaggerating up above; I really do struggle to wrap my head around his talent. Most hitters have identifiable holes, places where they sacrifice one thing to gain greatly in another area. Level, four-seam-punishing swing? You likely struggle with sinkers low in the zone. Patient approach that hunts fastballs and waits out secondary pitches? Breaking balls in the zone will be your Kryptonite. Whip-quick pull hitter? You might struggle with pitches away.

Rays Go Full Rays, Trade Austin Meadows to Tigers for Future Considerations

In a normal baseball offseason, all the trades would have already happened. Front offices have all season to call each other up with a million permutations of deals, and the deals they make spawn other deals, and player injuries spawn other deals, and free-agent signings lead to surpluses or needs, and… well, you get the idea. Trading flurries happen in December, and during spring training, and teams work out their rosters that way.

With a compressed offseason thanks to the lockout, the timeline has gotten all mixed up. Now, trades are happening three days before opening day. It’s madness! And speaking of:

Tigers Get

Rays Get

This trade was announced last night, and I’m writing about it this morning, and so rather than write a block of text about one side’s return and then a block of text about the other, I’m going to try a slightly different framing tool: I’ll walk you through a few levels of how I’ve thought about this deal. It’s an interesting one, no doubt, as trades involving the Rays so often are. Let’s get started!

2022 Positional Power Rankings: Starting Rotation (No. 1-15)

© Wendell Cruz-USA TODAY Sports

Earlier today, we looked at the teams in the bottom half of the league’s rotations. Now to close out the positional power rankings, we look at the game’s best.

Finally, you’ve reached the last positional power rankings entry of the year. It’s also the most powerful power ranking of the bunch — all the others have had to settle for five or so absolute superstars, but through the magic of counting entire rotations together, we’re looking at an embarrassment of riches here. Twenty-four pitchers in this writeup are projected for three or more WAR this season — good luck matching that at shortstop. And that doesn’t even count the bottom half of rotations (sorry, Shane Bieber, you’re still cool, though). Considering a group of eight-ish starters instead of one-ish starter and his backups for each team means that there are going to be more good players by default.

If you’ll allow me to indulge in a bit of inside baseball, starting pitching rankings are different in one other major way: the attrition on this list has been strikingly high. If you could go back in time a month and look at the second base power rankings, they’d look basically the same as they do now. Marcus Semien? Good then, good now. Maybe the occasional signing or trade shook things up, but for the most part, nothing has changed. When it comes to pitchers, nothing is constant. Seemingly every day, someone goes down with injury. Take a snapshot a week ago, and White Sox would have graced the top five. The Padres added Sean Manaea, then saw Mike Clevinger’s projected innings total take a hit. There’s no more volatile position in the game. That’s modern baseball in a nutshell — starters are hugely important, and they’re also quite breakable. Your team’s fortunes depend in large part on these units, and they in turn depend in large part on extremely breakable ligaments and tendons. Read the rest of this entry »


The White Sox and Blue Jays Swap Backup Catchers

Geoff Burke-USA TODAY Sports

If I told you that two contending teams swapped major leaguers, you’d probably have an idea of what that looks like. Maybe a reliever and a fourth outfielder changed hands, or something like that. The Blue Jays and the White Sox didn’t do that, though; they swapped catchers, as Jeff Passan first reported:

But even though both Reese McGuire and Zack Collins play catcher, they do so in very different ways. Amusingly, as we at FanGraphs work through our Positional Power Rankings, Collins is essentially positionless power. His home run totals in the minors and batted ball metrics in the majors tell a consistent story; if he can figure out a way to limit his strikeouts, he’ll be a fearsome hitter.

In a previous era, that might have secured him a starting catching role. But our newfound understanding of the value of receiving has exposed Collins as one of the worst defenders at the position — one who was worth a ghastly 14 runs below average in only 506 innings of catching last year. It’s not an easy skill to show with a GIF or two, and that sounds like a ton of runs to surrender in such a short time. But that matches up with the eye test, and the Blue Jays will likely use Collins mainly as a first baseman and DH.
