Starting pitchers prepare for games in three-stage fashion. A few days after taking the mound, they throw a bullpen session under the watchful eye of the pitching coach, typically with a Trackman recording each throw. At the start of every series, there is a pitchers’ meeting with all arms present, as well as the catchers and pitching coaches. On the day of a start, the pitcher will go over that day’s game plan with the catchers and coaches.
And then there are the talks pitchers have among themselves. While informal, they can likewise play a meaningful role in preparedness. Every time a hurler takes the hill, he brings with him knowledge gleaned from his peers. That was a big part of what I was interested in when I approached three starters — Lucas Giolito, Kevin Gausman, and Ryan Pepiot — to learn how they get ready for an outing from an information perspective.
Here are excerpts from my conversations with the pitchers:
———
PRE-SERIES AND PRE-START MEETINGS
Giolito: “You go over a lot of things in the pre-series meeting. You go over guys who like to run — stealing bases and things like that — and you obviously go over the hitters. Considering that you have a bunch of dudes in the room that have wildly different stuff and attack plans, that’s more surface level. You’re not going down the line and saying, ‘This is how we’re going to attack this guy,’ because we’re all different. That’s for when you have your pre-start meeting.
“In the pre-start meeting — that’s with the coaching staff and the catchers — we go over each hitter, talking about strengths, weaknesses, and attack plans. The attack plans are based on the individual pitcher’s stuff.” Read the rest of this entry »
On last Monday’s episode of the Rates and Barrelspodcast, Derek VanRiper raised a curious contradiction. “[Riley Greene is] first percentile in squared-up percentage, but 97th percentile in barrel rate, which — I’m sure there’s an explanation, I don’t know what it is just yet.” In response, Eno Sarris asked, “How can he barrel it without squaring it up?” It was a great question. In colloquial use, a squared-up ball is synonymous with a barreled ball. So what’s going on here, exactly?
The first thing to know: A squared-up ball is not necessarily a well-hit ball, as Davy Andrews highlighted when these stats were first made public last June. To understand why, one must first become acquainted with the Statcast definition of squared up. The MLB glossary entry for squared-up rate defines it thusly: “A swing’s squared-up rate tells us how much of the highest possible exit velocity available (based on the physics related to the swing speed and pitch speed) a batter was able to obtain – it is, at its simplest, how much exit velocity did you get as a share of how much exit velocity was possible based on your swing speed and the speed of the pitch.” If a hitter generates 80% of their possible exit velocity on a given swing and the ball is put in play, the batted ball is considered squared up.
We might quibble over the simplicity of that definition. In any case, as Davy showed, squared-up balls can be hit at super low speeds — if all it means is that a hitter channelled 80% of the potential exit velocity, then 80% of a half-swing is not very much exit velocity.
It’s also possible to do damage without making frequent flush contact; Greene shows us how. As Ben Clemens wrote just a couple of weeks ago, Greene is posting yet another excellent offensive campaign despite one of the higher strikeout rates among qualified hitters. He’s doing it unconventionally, swinging a ton in early counts to maximize damage. He’s also unconventional in another sense: He barrels the ball a ton while hardly ever squaring it up.
Part of the explanation for how this works is tied to the nature of swinging hard. When the bat speed statistics first dropped, it immediately became clear that there is a strong negative relationship between bat speed and the ability to square the ball up, at least by the Statcast definition. Click over to the bat tracking leaderboard, and the first thing you’ll see is this image, which shows the negative correlation between these two variables:
That’s no surprise. By the Statcast definition of a squared-up ball, slow swingers will always come out on top, because swinging slower allows for greater barrel accuracy. But it’s not all bad news for hard swingers. They also tend to produce the most valuable type of batted ball: a barrel.
Naturally, bat speed is correlated — positively — with barrel rate. A barrel, by the Statcast definition, is any type of batted ball where the expected batting average is at least .500 and the expected slugging percentage is at least 1.500. Barrels tend to be clustered in a pretty narrow exit velocity/launch angle range, somewhere north of 100 mph in terms of exit velocity and between 15 and 40 degrees or so of launch angle:
As the scatterplot below shows, the relationship between bat speed and barrel rate is extremely tight:
Greene’s average bat speed — 75.2 mph — is in the 91st percentile, so on some level, a high barrel rate and a low squared-up rate is to be expected. Even so, the spread between these two metrics is striking. His barrel rate is higher than his squared-up rate! Only one other hitter has a lower squared-up-minus-barrel rate — Aaron Judge. And that gives a hint into how, exactly, Greene is pulling this off.
Judge racks up an obscene number of barrels. Already, he’s mashed 60 this year, good for a 25.9% barrel rate. Like Greene, his squared-up rate is low — not as low, but comfortably a standard deviation below the mean. But also like Greene, Judge is amazing at converting his squared-up balls into barrels.
Nobody comes particularly close to Judge in this metric. Nearly 40% of his squared-up balls are converted into barrels, by far the highest rate in the league. (The league average is 13.6%.) As you might have guessed, Greene also excels here, ranking fifth among all hitters with at least 150 plate appearances:
So that’s the first part of this equation. Greene might not square the ball up that often, but when he does, it’s frequently crushed. The other part of the equation? Greene hits a ton of foul balls.
Greene’s 315 foul balls rank fifth among all hitters. When Greene makes contact with the ball, it goes foul 56% of the time. That mark ranks 11th out of all hitters with at least 150 plate appearances; besides Cal Raleigh, nobody else in Greene’s squared-up-to-barrel cohort fouls off nearly as many balls:
Minimum 150 plate appearances. Foul balls divided by pitches that end with contact.
All of those foul balls — in addition to his seventh percentile whiff rate — contribute to the squared-up percentage denominator, sinking Greene’s squared-up rate to the very bottom of qualified hitters. Importantly, foul balls are not part of the barrel rate denominator. The barrel rate that shows up on the Savant player page popsicles is a measure of barrels per batted ball event. A bunch of foul balls do nothing to affect a hitter’s barrel rate, but they’ll go a long way toward tanking a squared-up rate.
It isn’t necessarily intuitive to think that a hitter could be so good at barreling the ball and so bad at squaring it up. But breaking it down in this fashion, I think it starts to clarify this ostensible conundrum. Barrels are hard to come by. Even Judge, the barrel GOAT, hits one just over a quarter of the time he puts a ball in play. To be a barrel king like Judge or Greene, you don’t need to crush that many baseballs, at least on an absolute basis. But you better make sure that when the ball is in play, it gets smushed.
More than anything, I think these two data points paint a compelling picture of the modern hitter. Greene, perhaps more than any other hitter, goes for broke, almost like the anti-Luis Arraez. His swing tilt is the steepest in the sport. He mishits a bunch of pitches. He whiffs a ton. But when he connects, he does damage. And even though those damage events are relatively infrequent, they’re valuable enough to make him one of the better hitters in baseball.
Last night, exactly one week before they’re slated to make the first overall pick in the 2025 draft, the Nationals fired president of baseball operations Mike Rizzo and manager Dave Martinez. After ESPN’s Jeff Passan broke the news, the team announced assistant general manager Mike DeBartolo will serve as interim GM. Bench coach Miguel Cairo was named interim manager this afternoon.
Rumors that Rizzo and Martinez might finally be on the hot seat had made the rounds over the past several weeks, but the timing is less than ideal. According to Ken Rosenthal of The Athletic, the last time a team fired its GM before the trade deadline was when the Twins got rid of Terry Ryan on July 18, 2016. USA Today’s Bob Nightengale provided an explanation, reporting that both Rizzo and Martinez had contract options for 2026, with mid-July deadlines for those decisions. Even for a franchise that just fired its POBO and manager, it’s a bad look to let money dictate the timing of the decision when so much is at stake. Read the rest of this entry »
There’s never a good time to lose a starting pitcher, but doing so when you’ve lost six of your last seven games and have relinquished first place in your division is an especially unwelcome happenstance. This is what the New York Yankees are currently experiencing, as Clarke Schmidt, who was placed on the injured list due to forearm tightness after an early exit from his Thursday start, will likely undergo Tommy John surgery. With a 3.32 ERA, 3.90 FIP, and 1.2 WAR in 14 starts, Schmidt appeared to be headed towards his best season in the majors, but short of a miracle, he’ll now be out until well into the 2026 season at least. Coming just as the offense appeared to be recovering from its June swoon, the Yankees’ trade deadline to-do list may have just gotten a bit longer.
Six weeks ago, the Yankees were in a strong, though not insurmountable, position at the top of the AL East. No fan should start making travel plans based on a seven-game divisional lead in late May, but it’s about as strong a position as a team can hope to have in a good division. In his May 28 start, Schmidt threw six shutout innings en route to a 1-0 victory over the Angels, giving the Yankees that a seven-game lead (their seasonal high-water mark) and a 35-20 overall record. Since then, the Yankees have gone 14-21, losing 11 games in the standings relative to the current first-place team, the Blue Jays.
The disappearance of the offense was a big part of the Yankees’ slump, at least until the last week or so. On the whole, the offense dropped to a .718 OPS in June after posting an .812 OPS through the end of May, a mark that was second only to the Dodgers. Half of the team’s plate appearances in June were made by players with a wRC+ under 90 for the month, including key early-season performers Paul Goldschmidt and Ben Rice, as well as a returning Giancarlo Stanton. The pitching remained solid despite the team’s 13-14 month, with the rotation combining for a 3.19 ERA and a slightly less exciting 3.79 FIP. Read the rest of this entry »
Below is an analysis of the prospects in the farm system of the Washington Nationals. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the fifth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.
A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.
All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Since 2021, Ke’Bryan Hayes is the leader in OAA among all infielders. As one of the best defenders in the sport, his floor is very high. Even with his career 87 wRC+, he has still been worth about 3 WAR per 162 games. If he could be a consistently average offensive player, he’d be one of the most valuable players at his position. This is a story we all know. With his name swirling in trade rumors, you have to imagine other teams are thinking about the possibility more so now than in the past. His issues stem from his suboptimal swing path, and if he’s traded, that will be what his new hitting coach tries to fix.
In the last calendar year (459 plate appearances), Hayes has a 60 wRC+. That is bad! But despite those struggles, it’s not like he is completely lacking offensive ability. His bat speed is only a little below average. His strikeout and whiff rates are better than league average over the past three seasons. He hits the ball hard more often than not, and he chases at about an average rate. Those are all things you could work with if you’re trying to manufacture a league average hitter. But if you’re doing all this and your path is rarely working in an ideal direction, you’ll always have limitations on what you do when you actually make contact. Read the rest of this entry »
“If you’re taking follow up questions, I’d like to hear how he differentiates intention and conviction from physical effort. How difficult is it to mentally commit to the pitch but only give it 90% so you keep some gas in the tank? Is it even possible to do so?”
Fortuitously, an opportunity to circle back with the future Hall of Famer came just a few days later when the Blue Jays visited Fenway Park for a weekend series. As expected — Scherzer likes talking ball — he was amenable to addressing said followup.
“Effort level and conviction are different,” Scherzer answered. “You can throw a pitch at 100% effort and still be mentally indecisive about it. You can also put out less than 100% effort and be mentally convicted in what you’re doing. Can things go hand-in-hand? Yes, but it’s not ‘more effort means more conviction.’ You can just be more mentally convicted.”
Scherzer had opined in our earlier conversation that you’re more likely to miss your spot when not fully convicted. What about throwing with full conviction at a 90% effort level? Does that make it easier to pinpoint your command? Read the rest of this entry »
Ben Lindbergh and Meg Rowley banter about Paul Skenes’s new interest, Clayton Kershaw and the evolution of 3,000-strikeout celebrations, and the deepening deadball era in Japan. After that (24:37), frequent Stat Blast Correspondent Ryan Nelson joins to discuss why there have been so many team shutouts this season and then deliver several Stat Blasts, followed (1:02:56) by postscript updates.
Hello FanGraphs Members and readers. I hope all of you here in the U.S. are enjoying your holiday weekend. I’ve spent much of this week on vacation, so I didn’t get to watch as many games as I usually do. Still, I followed some of the action from afar, enough to see Clayton Kershaw record his 3,000th strikeout, the Yankees fall out of first place, and the All-Star Game’s starters be named.
Before we get to all that, I’d like to remind all of you that while anyone can submit a question, this mailbag is exclusive to FanGraphs Members. If you aren’t yet a Member and would like to keep reading, you can sign up for a Membership here.

Ben Lindbergh and Meg Rowley banter about how many members of the All-Star Celebrity Softball Game roster they have heard of, honorary all-stars, and velocity spikes preceding arm injuries, then discuss an investigation concerning possible pitch-fixing by Luis L. Ortiz, a federal civil rights complaint about the Dodgers’ DEI policies, and Rob Manfred’s pitch to players in advance of CBA discussions.
