I’ve spent way too much time pondering how to begin this article. So instead of formulating a timely and witty introduction, I’ll be direct: The Blue Jays offense is amazing! You already know that, but it bears repeating. Together, Jays hitters have amassed the league’s second-highest wRC+ while maintaining the league’s second-lowest strikeout rate. This is scary, and this is legit.

Right now, the only team with a higher wRC+ is the Astros. The only team with a lower strikeout rate is… also the Astros. And it’s easy to explain. They don’t have the most power or the best discipline, but they do lead the league in O-Contact%. Even when would-be balls are swung at, they’re either put in play or fouled off. Couple that with a minuscule swinging-strike rate of 8.7%, and it’s a team poised to give opposing pitchers fits. Tenacity wins.

As for the Blue Jays, however, their formula isn’t immediately noticeable. Duh, they have the best hitter on the planet. I know, imaginary voice, but I’m talking about the team as a whole. A few days ago, the Jays routed the visiting Red Sox, outscoring them by eight runs. Let’s consider how the ambush unfolded. Nathan Eovaldi had managed to salvage a rough start until the fifth inning, when Teoscar Hernández unleashed his full strength against a first-pitch fastball:

On July 26, the Seattle Mariners experienced what was perhaps the apex of their season. Down 6-0 against the Astros until the third inning, they embarked on an improbable rally that would culminate in an 11-8 victory. Let’s take some time to admire Dylan Moore and his swing, which produced the grand slam that punctuated the uphill battle:

Chills! It was a great moment, and not just for Mariners fans but for baseball in general. Who doesn’t love a cathartic underdog upset? (Well, maybe not the Astros in this moment.) But it was also a reminder of how the team had gotten to that point. Despite an ugly run differential, the Mariners had managed to squeeze out key wins throughout the season. This latest against the Astros gave them a 55-46 record. Suddenly, a Wild Card berth didn’t seem out of reach.

Two weeks later, the Mariners are still going. I had planned to write this article as early as July 24, when I tweeted about the team’s offense. In the back of my mind, I sort of assumed they’d fizzle out. But here we are, and the Mariners have a respectable 58-51 record – three games behind Oakland, and just a few more behind Boston. No team has been more clutch. Read the rest of this entry »

It’s been leading up to this all week. The endless rumors, speculation, and fake Twitter accounts paved the way for two earth-shattering transactions. I’m talking, of course, about the Red Sox sending Aldo Ramirez to the Nationals in exchange for Kyle Schwarber, and San Diego shipping Mason Thompson and Jordy Barley to Washington in exchange for Daniel Hudson.

I kid, but we can’t let the Dodgers hog the spotlight, can we? Besides, as far as trades go, these are as straightforward and sensible as they can get. Up first are the Red Sox, who will try to make the most out of two months with Kyle Schwarber. The 28-year-old slugger went on an absolute tear a month ago but has missed time since with a hamstring injury. That means the team will have to wait before it can use his services, but that’s a small sacrifice when considering the potential benefits.

Immediately, Schwarber provides the Red Sox with a left-handed, middle-of-the-order bat. Our Depth Charts have him pegged at left field and first base – the former option establishes some stability in a scrambled outfield, while the latter offers a temporary respite from the clutches of Bobby Dalbec, whom Jay Jaffe highlighted as a replacement-level killer in his recent series.

In theory, the skewed dimensions of Fenway both aid and hinder Schwarber. Using our site’s Park Factors, we see that the park has consistently suppressed home runs from lefties while enabling doubles. But it won’t dramatically alter Schwarber’s value, and while he does strike out a fair amount, it’s not because he’s swinging at bad pitches. As Eno Sarris pointed out, Schwarber is one of the few hitters with elite barrel and chase rates. Here’s that visualized, with him as the point in red:

I also wonder if the Red Sox are willing to modify Schwarber’s approach. His swing rate in early counts (0-and-0, 0-and-1, 1-and-0) is below the league average; by contrast, the Red Sox have a penchant for attacking early – not against all pitches, but rather would-be strikes. It’s a method of selective aggression that’s powered the team thus far. Schwarber already doesn’t chase often, so maybe more swings at early strikes would boost his offensive output and prevent him from falling behind in the count.

Given the nature of Schwarber’s contract, headed to the Nationals is a single prospect: Aldo Ramirez, a right-handed pitcher ranked 14th on Eric Longenhagen’s preseason Red Sox Prospects List. Ramirez is currently on the IL with elbow tendinitis. Eric informed me that prior to his injury, Ramirez had been performing well after a velocity spike during the fall. Other details to note are an arm slot and hand position conducive to pitching up in the zone, a “fairly advanced arm-side changeup feel,” and a command grade that’s currently at 35 but that has been assigned a FV of 60. It’ll be crucial to monitor whether the gains in velocity are still present when Ramirez recovers. He slots in at eighth in the Nationals system.

Moving over to the West Coast, we have the Padres’ acquisition of Daniel Hudson. I know, it’s hardly a consolation after missing out on Scherzer – someone I follow on Twitter described the fallout as ordering a filet mignon and getting a salad instead – but Hudson has been quietly awesome. In terms of numbers, his 2.20 ERA, 2.45 FIP, and strikeout rate of 37.8% place him among this season’s very best relievers.

To say this is unexpected might be an understatement – at age 33, Hudson’s strikeout rate soared from 23.4% in 2019 to 30.4% in ’20. The secret involved adding a few inches of ride to his fastball, abandoning his sinker and changeup, and throwing more sliders. In short, he transformed himself into a modern reliever. But when it came to actual results, Hudson’s home run and walk rates spiraled out of control in 2020 and contributed to career-low marks. I do think most of that can be blamed on the variance within a 20-inning sample, but I also did notice a particular quirk. Here’s Hudson’s whiff rate on his slider when he fell behind in the count since 2015:

You can easily spot the great crash of 2020. For some inexplicable reason, batters became resistant to Hudson’s slider that season, forcing him to rely on his fastball. I’m not sure if this was a contributing factor, but it did inspire Hudson to revise his slider. Unlike previous iterations, the pitch is now released at an 180-degree axis (i.e. as vertically as possible). That’s led to a loss in vertical drop but also an uptick in velocity, which perhaps interacts better with his fastball. Though I’m a bit skeptical about Hudson’s suppressed walk rate, it seems like his resurgence is no fluke. Note: Hudson is currently on the COVID Injured List, so it will be at least a couple of days before he is activated.

In return, the Nationals will receive two mid-level prospects: Mason Thompson and Jordy Barley. A shortstop signed out of the Dominican Republic in 2016, Barley possesses loud tools but has fallen behind in development due to his on-field mishaps. He’s an interesting prospect, though it will take a while to gauge whether he ends up benefiting the Nationals.

Meanwhile, right-handed pitcher Mason Thompson is someone who’s been on my radar since his Padres debut. Of the 43 pitches he’s thrown so far at the major league level, 41 have been sinkers; the other two are a stray four-seam fastball and changeup. That’s because he can absolutely afford to. In addition to hovering around 96-99 mph, his monstrous sinker generates around 60 degrees of axis shift as it reaches home plate. But as Eric Longenhagen noted in his write-up of the Padres’ system, command is still an issue for Thompson. Whether he can harness the sinker in tandem with a secondary pitch will be key in deciding his future value. Thompson ranks 21st in his new system, while Barley checks in at 26.

Contenders benefit from a team willing to sell. It’s a simple outcome, but one that the uncertainty surrounding this year’s deadline threatened to distort. In the end, though, a blockbuster was released, and two additional buyers came out on top. The Red Sox snagged a power lefty bat who could mend a hole at first. The Padres brought in a veteran reliever with two electric pitches and postseason experience. On the selling end, the Nationals netted three prospects with intriguing upside, bolstering a farm system that ranked towards the bottom of most publications’ lists. Everyone should be satisfied here.

It was a hectic day on the trade market. First, news broke that the Pirates had traded Tyler Anderson to the Phillies. Shortly after, the Mariners provided extra heat to the stove by sending relievers Kendall Graveman and Rafael Montero to the Astros in exchange for Abraham Toro and Joe Smith. They didn’t stop there, swooping in to nab Anderson and taking advantage of an issue that surfaced with one of the two Phillies prospects originally headed to Pittsburgh.

The number of tweets dwindled as the night rolled in, signaling an end to the frenzy. We would have to wait until tomorrow for more deadline shenanigans, but I suppose a bonus transaction couldn’t hurt, because out of the blue, the Yankees’ Twitter account dropped this bit of news:

The New York Yankees have announced that following Tuesday’s game they traded RHP Luis Cessa and LHP Justin Wilson to the Cincinnati Reds in exchange for a player to be named later.

A trade announcement at 12:35 AM Eastern Time? Sure, why not. Let’s break this one down.

We at FanGraphs haven’t checked in on the Rockies in a while. To put it nicely, that’s because they are performing as expected – a 43-55 record has banished them to fourth in the NL West, a place the team will probably call home for the remainder of the season. As a whole, the Rockies have a league-trailing 75 wRC+. It is not a good sign when C.J. Cron is the best hitter on your team by a wide margin.

But the pitching? After adjusting for the wackiness of Coors, the Rockies’ pitching staff has an ERA- of 100. It also has a FIP- of 101. I suppose one could do better than that, but one could also do worse, and being an average arm in Denver is an accomplishment of its own.

A major reason for this is the resurgence of Germán Márquez. After a rocky April and May, it’s safe to say the Rockies’ most reliable pitcher has settled in. What do we know about Márquez? There are his two breaking pitches, a curveball and a slider, each one a plus offering that hitters whiff at over 40% of the time. But what’s not talked about as often is his four-seam fastball. That in itself isn’t surprising, since the fastball has long been Márquez’s worst pitch. What is surprising, though, is how good it’s been in recent months. Consider the plot below:

Márquez is the point in yellow. Since June 1 (and through last Thursday’s action), his four-seamer has averaged the lowest launch angle among the 97 shown. It has averaged the lowest wOBA, too, a result of the first fact. The pitch has always induced groundballs at a healthy rate, but that quality seems to have been kicked into overdrive during this two-month stretch. Read the rest of this entry »

For the past few days, I’d been searching for a baseball topic to write about. It usually takes less time, but we’re in that calm (if not monotonous) period between the All-Star break and the trade deadline. Ideas are scarcer. Maybe I’d settle on an article with a simple premise?

So I committed myself to tackling pitcher BABIP. (Good going, Justin!)

The notion that pitchers have no control over what happens to a ball in play ushered in a golden age of baseball research, and findings from back then still influence how we view the game today. But over time, we realized that exceptions do exist; for example, Clayton Kershaw consistently allows a below-average BABIP, most likely because he’s a phenomenal pitcher. In addition, certain pitchers have a knack for inducing weak contact in the form of pop-ups or grounders. Exactly how those batted balls impacted BABIP remained a mystery, but you could no longer brush off the metric as total noise.

Years later, Statcast data became available for public use. Even so, research on pitcher BABIP remained far and few between; it’s a daunting subject! I did use two articles as inspiration, however. The first is from FanGraphs user rplunkett97 on our community research page. Dating back to 2017, it mainly discusses a linear model with several variables (BB/9, GB%, Team UZR, and more) used to produce an expected BABIP for each pitcher. The second is courtesy of Alex Chamberlain, also from the same year, who used a mixture of Hard-hit and Barrel rate to create his own version of xBABIP.

Adam Frazier is a Pittsburgh Pirate. He’s also been good, which means contending teams will look to acquire him at the trade deadline. What organization wouldn’t want an above-average defender who’s also hitting .330/.397/.463? To give that another spin, his 137 wRC+ is third-best among second basemen with 300 or more plate appearances, right behind Max Muncy and Jose Altuve.

But you might have visited his FanGraphs page, scrolled to the numbers, and seen a red flag – that Frazier’s .366 BABIP is abnormal, considering his career before this season. That’s not all: There are significant differences between his actual stats and Baseball Savant’s expected stats, such as slugging percentage and batting average. He’s hit just four barrels so far, none of them surpassing the 110 mph mark.

So yes, it does seem like Frazier is biting off more than he can chew. But I think we can do better than the boy who cried regression because, well, what if he’s doing something new that’s contributing to his higher BABIP? The second baseman has always been one to make consistent contact while minimizing whiffs, so it’s plausible he’s unlocked a new gear. Back in May, I broke down Freddie Freeman’s uncharacteristically low BABIP by batted ball type, so let’s do the same for Frazier. Where is he getting his money’s worth? And compared to the league average, where is he falling behind?

These numbers are from our Splits Leaderboards, and they tell an intriguing story. Frazier is worse than average when it comes to line drives, which might be because of his middling power – a weak liner is usually an automatic out. Despite this, he’s making up for lost production via grounders and… fly balls? That’s odd. Somehow, Frazier’s fly balls aren’t leaving the ballpark or being caught by outfielders. Instead, they’re landing for hits. Read the rest of this entry »

If you’re a baseball nerd like me, you’ve likely seen this graph (or a variation of it) before:

wOBA by Launch Angle

The focus should be on launch angles between 0 and 36, or better at 8-32 degrees.

Once you get below 0 or above 36, it's hard to be productive. Again, we don't care about "average" launch angle, but the frequency you can get into the "sweet spot". pic.twitter.com/7JYOPGAd4c

— Tangotiger ? (@tangotiger) October 14, 2018

Yep, it’s an illustration of how launch angle affects wOBA. And Tango’s iteration, like many others, is told through the hitter’s perspective. That makes sense – we seldom think about launch angle with respect to pitchers, since it’s trickier for them to control the contact they allow. We do know in a broad sense that there are groundball pitchers and fly ball ones, hence why metrics like xFIP and SIERA remain relevant.

But specific launch angles can also be useful in assessing pitchers. About a week ago, I shared this graph with my Twitter followers:

Here, I should clarify that what’s being measured is the year-to-year correlation of the percentage of batted balls within select launch angle ranges. What can we take away from this? It turns out that pitchers are much better at controlling the amount of extreme contact they allow. Going down the list, line drives are a capricious bunch. What we regard as standard groundballs and fly balls are a bit more manageable. When it comes to slap hits or pop-ups, though, pitchers surprisingly account for about half the variance. Go pitchers!

“We gave Pham up for Renfroe and a damn slapdick prospect?” Blake Snell bemoaned live on Twitch. He was reacting to a trade between the Rays and the Padres that took place during the 2019-20 offseason. Snell’s annoyance caused a bit of controversy – he ended up reaching out to said prospect, Xavier Edwards, to smooth things over – but it also popularized the term, to the point that it’s now part of our baseball lexicon.

What does it mean exactly, though? Urban Dictionary informs us that a “slapdick” is more or less an incompetent person (to put it nicely), but that doesn’t feel quite right in a baseball context. For me and presumably others, a slapdick hitter is someone who doesn’t hit for power and earns his keep by spraying the ball around – someone like Nick Madrigal. Although the Rays currently do not roster Madrigal, they do have this: As of this writing, their hitters collectively have the highest BABIP (.264) and wRC+ (57) on groundballs. A slapdick hitting team.

If your sabermetric senses are tingling, I understand. Due to the fickle nature of BABIP, continued success on grounders is a tenuous endeavor. It’s entirely possible the Rays have gotten lucky over the past few months. But in the spirit of FanGraphs, I began to wonder if there’s an extra dimension to this. The numbers, in fact, do posit an interesting idea – that the Rays have set themselves up for success on grounders, more so than most teams this season. Read the rest of this entry »
