When the market is hot, it seems like it’ll never cool down. Forget the fact that we’re late into free agency and yet too early in the year for contract extensions. The last few marquee free agents to sign are starting to do so – hi, Cody – and that seems to have opened the floodgates for a series of trades. You’ve heard about all the noise the Mets have gotten up to, no doubt. They aren’t the only ones. The Rangers have jumped in on the action in a big way. On Thursday, they acquired MacKenzie Gore from the Nationals in exchange for prospects Gavin Fien, Devin Fitz-Gerald, Alejandro Rosario, Abimelec Ortiz, and Yeremy Cabrera, as Jon Heyman of the New York Post first reported.

In some ways, this trade has been a long time coming. Gore has been on the trade block for most of his major league career. First, he got sent from San Diego to Washington in the first Juan Soto trade. Almost immediately upon his arrival in the nation’s capital, however, he turned into a trade chip. The Nats were pretty obviously far away from competing, and Gore is the kind of arm that lots of teams dream about placing at the top of their rotation.

By 2024, Gore’s third year in the big leagues, the trade rumors were at full volume. Gore exploded out of the gate, with 98 strikeouts over 80 innings in his first 15 starts. He was a deadline target for many teams – but he slumped hard down the stretch, with a 4.48 ERA and 4.16 FIP the rest of the way, and no trade ever came to fruition. The Nats looked around that winter, didn’t move him, and then again held on after Gore came out of the gates hot, making his first All-Star appearance on the back of a 3.02 ERA (2.96 FIP) in the first half. He stayed put at the deadline – and once again slumped hard down the stretch.

That brings us to the present. Trading Gore always made sense, and the new Nationals front office finally did it. He still has two years of team control remaining, and the price for controllable starters has never been higher. His service time status lines up very well with the situation in Arlington. The Rangers have a roster that is built to contend now. Their lineup has five different hitters in their 30s (baseball-age wise, Jake Burger doesn’t celebrate his 30th until April), and only two who are 25 or younger. The rotation is led by Jacob deGrom and Nathan Eovaldi, two heroes of the 2010s who are in the twilight of their respective careers. Read the rest of this entry »

Our long national nightmare is over. After weeks of back and forth between Cody Bellinger and the New York Yankees, it’s official: He’s staying in the Bronx. The two sides have agreed to a five-year, $162.5 million deal with opt outs after the second and third seasons, a $20 million signing bonus, and a full no-trade clause, as first reported by Jeff Passan.

This fit was so obvious that it almost had to happen. The Yankees need offense, and they’d prefer it to come in the form of a left-handed outfielder who can cover center field in a pinch. They’re already familiar with Bellinger, who just put up a 5-WAR season in pinstripes. No other teams needed this exact type of player as much, at this current moment, as they did. Likewise, Bellinger was probably going to have to sign with the Yankees to get the deal he wanted. Now that that foregone conclusion has been reached, let’s unpack how this all fits together.

This contract is the culmination of a long, decorated career that was conspicuously lacking in free agency appeal. Bellinger burst onto the scene in 2017 with 39 homers for the Dodgers, taking Rookie of the Year honors in the process. He then went fully supersonic in the homer-happy 2019 season, with the rocket ball propelling him to 47 homers, a 161 wRC+, and NL MVP honors. Disaster struck in the 2020 World Series, however. Bellinger dislocated his shoulder celebrating a home run, and his performance fell off a cliff immediately after. Read the rest of this entry »

With most of the top free agents having found new homes – 12 of our top 15 have signed – the baseball transaction news figured to be light this week. Maybe the Yankees and Cody Bellinger would keep making lovey-dovey eyes at each other across the negotiating table to give us some headlines, but that felt like the only game in town for at least a few days. But just because no one is left to sign doesn’t mean nothing can happen. Out in Queens, the Mets weren’t content to sit pat after signing Bo Bichette. They continued their offseason splurge by acquiring Luis Robert Jr. from the White Sox in exchange for Luisangel Acuña and pitching prospect Truman Pauley, as ESPN’s Jeff Passan first reported.

I’ve grappled with evaluating Robert innumerable times over the past few years. For a while, he was a yearly feature in our Trade Value series, an electric talent in his early 20s. Then he became an interesting litmus test when talking to team evaluators, as his production dipped but his prodigious tools remained as loud as ever. Finally, as his contract hit the expensive team option phase, I considered him for a list of top free agents, as I have to predict what option decisions teams will make. At every turn, I came away equally impressed and frustrated by Robert’s ludicrous ceiling and subbasement-level floor.

You want a tooled-up center fielder? Robert is your guy. If you click on the “Prospects Report” tab on his player page, you’ll see this short blurb by Eric Longenhagen: “Graduation TLDR: The Vitruvian Outfield Prospect in all facets save for his approach, Robert graduated from prospectdom as one of baseball’s most exciting players.” That Vitruvian Outfield Prospect phrase has stuck with me.

If you made an outfielder in a lab, he’d look a lot like this. Power? Robert has 90th-percentile bat speed and clobbered 38 home runs in his last full season of playing time. He gets the ball in the air, too, all the better to maximize his best contact. Speed? You guessed it, 90th-percentile sprint speed. He’s also among the best defensive outfielders in the game when he’s healthy. He even has a strong throwing arm, though it’s inaccurate at times. If you’re looking for a Gold Glove defender who can hit 40 homers at the hardest outfield spot and swipe 30 bags, he’s one of maybe three players in the entire majors who fits the bill.

Over the weekend, Ha-Seong Kim’s whirlwind offseason took a jarring tumble. After opting out of his contract with the Braves (really his contract with the Rays, which the Braves assumed after they claimed him off waivers), he turned around and signed a one-year, $20 million deal to remain in Atlanta. But disaster struck when he slipped on a sheet of ice and tore a tendon in his right middle finger. That injury required surgery that will sideline Kim for four to five months, including roughly the first two months of the regular season.

This will be the second straight season where Kim misses significant time due to injury. In late 2024, he tore his labrum on a pickoff throw, then injured his hamstring and later his calf while rehabbing, costing him the first half of 2025. He then hit the IL twice with back injuries last year. In all, he managed just 191 plate appearances and looked understandably rusty.

That star-crossed sequence has to raise questions about the future course of Kim’s career. How could it not? It’s not so much that any of these injuries are devastating on their own, but this much missed playing time over two-plus years of his prime is no laughing matter. Last year, he never hit his stride after a late start. This year, it’s fair to expect more of the same. Even without knowing how Kim’s injured finger might affect him upon his return, our projection systems have him down for a below-average offensive line. Read the rest of this entry »

Last week was one of the busiest of the offseason so far, with Kyle Tucker taking his talents to Chavez Ravine and Bo Bichette heading to the Mets. Given those glitzy headlines, it was easy to miss an annual rite of winter: a weird, zero-sum-feeling trade that didn’t need to be a three-teamer but was anyway because the Rays got involved. The particulars: The Rays sent Josh Lowe to the Angels, the Angels sent Brock Burke to the Reds, and Tampa Bay got Gavin Lux from Cincinnati and prospect Chris Clark from the Halos.

The first thing that drew my eye in this trade is that the two hitters are at least superficially similar: lefties with enormous platoon splits and no real defensive home. Lux has a career 99 wRC+; Lowe 101. They get to those marks in extremely different ways, though, and I think that’s as good of an entry point into analyzing this swap as any.

Lowe is an archetypical lefty power bat, and the Angels simply don’t have anyone like that. Last year was easily Lowe’s worst as a pro on a rate basis, and he also spent a month and a half on the IL. But his 11 homers would have been the second-most by an Angels lefty, behind Nolan Schanuel’s 12 in 150-ish more plate appearances (Yoán Moncada also hit 12 lefty homers, but he left in free agency). Overall, the Angels were 29th in baseball in home runs hit by lefties, with 34 for the entire team put together. Read the rest of this entry »

Our annual preview of free agency doesn’t include projected destinations for free agents. I don’t know if that has always been a site-wide editorial decision, but it’s one I wholeheartedly agree with. Predicting how much money someone will get is hard enough. Predicting which team out of many similar teams will give that money to them is essentially guesswork; sure, matching names to teams has entertainment value, but it’s hard to actually be good at it. Except, if you made me predict where Willi Castro would have signed before this offseason started, I absolutely would have picked the Rockies, and voila: Castro agreed to a two-year, $12.8 million deal with Colorado on Thursday.

The Rockies haven’t been players in free agency for a number of years, though that appears to be changing. Earlier this month, they signed Michael Lorenzen to a $8 million contract, the largest deal they’ve given to a pitcher in the 2020s. Castro’s deal is the biggest guarantee they’ve handed out to a free agent since Charlie Blackmon, and that hardly counts, what with him being a long-time Rockie signing the last deal of his career and all. Really, Castro is the team’s biggest signing since Kris Bryant, which says a lot about how the past few years have gone in Colorado.

What compelled the team to wade into the free agent position player pool – the shallow end, to be sure – for the first time in years? Signing a good major league player, that’s what. Castro is a versatile defender who won’t embarrass you offensively. In 2025 alone, he logged 100 innings at four different positions, plus cameos at shortstop and in center field. He’s not a standout at any of those spots, but the sheer flexibility is inarguably useful. Roster Castro, and you have a nice backup plan nearly everywhere. He’s a switch-hitter, too, so he can shore up any of the positions where you’d really prefer a platoon, regardless of who his platoon partner might be. Read the rest of this entry »

Yesterday, the Royals made a big announcement. Kauffman Stadium, long one of the most cavernous venues in the majors, is going to be a little less warehouse-like this year. The walls are moving in nine or 10 feet more or less across the board, and getting shorter by a foot and a half to boot. That’s a meaningful change for a stadium where home runs generally go to die. How massive? Time to crank up the old computer and find out.

I plugged the new dimensions from Kansas City’s press release into an equation describing a rough arc. I fit those points to a cubic spline so that it could more closely resemble the actual stadium, with its pinched-in corners. I made a few approximations as well; for instance, the wall is moving to a height of eight and a half feet “in most places,” so I just applied that across the board. I also modeled the old dimensions the same way. That way, I had two different virtual walls built to compare some batted ball data against.

Notably, my approximation isn’t a perfect replica of the stadium. I don’t have a millimeter-scale, or even a yard-scale, map of the place. I can’t account for outfielders robbing home runs, which is definitely going to be more common with the lowered walls, though still quite rare overall. But by running it through both the old and new wall dimensions, I think that this unavoidable error can be minimized. It’s pretty clear that no balls that were home runs with the old outfield parameters will suddenly not be home runs with the new ones, so the thing we’re looking for is the difference, assuming that my approximation is close enough to reality. And it is: My modeling says that over the last three years respectively, 205, 162, and 159 batted balls hit in Kansas City should have turned into homers. In reality, it’s been 186, 147, and 151.

Here’s a weird chart:

If you’re like me, you’re struggling to make sense of it. The value of a barrel? But aren’t barrels a measure of value themselves? That’s like asking how many dollars a ten dollar bill is worth, or how you’d rate The Lion King on a scale of one to The Lion King. But that’s not actually how it works. Barrels are defined based on exit velocity and launch angle pairs that, according to the dataset MLB used in their creation, were extremely likely to result in extra-base hits. Those cutoffs have remained the same. The results on barrels haven’t.

What gives? Well, some of it is the ball, of course. I’m not breaking new news in the long-running ball aerodynamics debate; you can read some good recent entries into tracking drag coefficients and the like here and here. Indeed, if you’re measuring barrels that way, you can see a pretty straightforward decline. Here are home runs per barrel over the years:

Earlier this week, I looked into the curious case of Benjamin Button. Er, no, that’s not right. I looked into the fact that the average age of big league hitters keeps declining, like Button, while pitchers haven’t followed suit. There are any number of possible explanations for that pattern, and if the mystery appeals to you, I highly suggest reading the comments of that article, where our excellent readers have advanced a number of solid theories. I think there’s plenty of meat left on the bone in figuring out what’s causing this trend, but I won’t be delving into that (much) today. Instead, I made like Woodward and Bernstein and followed the money.

Age is a decent proxy for service time; older players have generally, though not alway, been in the league longer than younger players. Similarly, service time is a decent proxy for salary; players who have been in the league longer generally make more money than newcomers, for a variety of reasons. So is our data really just saying pitcher salaries are going up? Well, kind of.

I took salaries for all major league players starting in 2019, discarding the abbreviated 2020 season. I split them up by type – pitchers in one bucket, hitters in another, and Shohei Ohtani in both. Total pitcher and hitter salaries have both gone up – passage of time, inflation, and so on. But after a huge increase heading into 2022, when seven different hitters signed nine-figure contracts, the total outlay to hitters has leveled off. Meanwhile, pitching salaries are catching up:

As an aside, I only pulled data through 2019 because it’s outrageously difficult to get complete salary data. If you’re looking for Opening Day annualized salaries, sure, those are reported. If you’re looking for free agency contracts, again, pretty easy to find. There are no disputes about what Freddie Freeman’s salary was in 2025; it’s public record. But what about Freeman’s former teammate Justin Dean, who racked up 52 days of service time in his debut season? What about split contracts? Late debuts? Up-and-down types? I worked out a method for what I consider a very good approximation of those salaries, but I don’t feel confident going back before the start of RosterResource’s database, which begins in 2019. Even then, this is approximate, though as I mentioned, I’m confident that it’s a good approximation. Read the rest of this entry »

I have a confession to make. I started this article with a conclusion in mind, only to find that that conclusion was spectacularly untrue. But then I pivoted, and found something else I think is quite interesting. Is it obvious, in retrospect? I kind of think so. But I had fun doing it and learned something in the process, so I decided to write about it anyway.

I had a theory that the average catcher age, along with the average age for all the hardest defensive positions, had plummeted over the past decade, with the average DH age increasing as a counterbalance. My theory was that the universal DH allowed teams to massively alter their behavior. National League teams that had been playing older sluggers in the field could shift them down the defensive spectrum, either directly to DH or by displacing other old players to DH via a chain reaction of moving to easier defensive spots.

It’s beautiful logic, with just one problem: It’s untrue. Here’s the average seasonal age (as of July 1 each year) of catchers, shortstops, and DHs since 2002, the first year we have positional splits that allowed me to run this analysis:

The data is pretty noisy, which makes sense to me. It’s not like teams are targeting a given age; they’re just making baseball decisions about cost, team control, and production. Average age is a downstream result of a lot of decisions that are made for other reasons. But in the aggregate, the pattern I hoped to see just wasn’t there:

In fact, DH has experienced the greatest decline in average age across all positions. That’s very much not what I expected. I do think that some of that is overstated. First base has had the smallest decline among positions, and I’d expect many of the displaced older hitters I mentioned in my hypothesis to end up there too. But if you average the age changes of first base and DH, they’re almost exactly the league average for position players. Clearly, the data do not support my claim. Read the rest of this entry »
