Let’s start with a thought experiment, then we’ll get to the guy in the picture up there. Say you’ve got an unhittable fastball. Every time an opposing batter swings at it, they miss. With such a pitch, you’d want to hit the strike zone every time. Only good things can happen in the strike zone. Either the batter takes and you earn a called strike, or they swing and you earn a swinging strike. Outside the zone, you’d run the risk of throwing a ball because the batter lays off it.

Now, say you’ve got an extremely hittable fastball. Not only does it never generate a whiff, but every time the batter swings at it, they also hit a home run. You’d never want to throw that pitch in the zone. You wouldn’t want to throw it much at all. Maybe you’d use it as a waste pitch to change the batter’s eye level, just every once in a while, and so far outside the zone that they wouldn’t even think about swinging at it. But that’s it.

Those are extreme examples, but my point is to introduce the concept of an ideal zone rate. Every pitcher (and every pitch) in baseball lives somewhere between those two extremes. Some pitchers should live in the zone and some should avoid it. All sorts of factors inform that ideal zone rate: how likely the pitch is to earn a whiff, how likely it is to earn a chase, how hard it tends to gets hit, whether it tends to gets hit in the air or on the ground, how it interacts with the rest of your repertoire, how it performs in different locations, how well you’re able to locate it, how confident you feel in it, the count, batter, situation, and so on, and so on.

Lately, the calculus has shifted somewhat. The zone rate has been rising because pitchers have been instructed to aim down the middle and trust in their stuff. In 2024, 49.6% of all pitches were in the strike zone and 26.5% were specifically in the heart zone (the area at least one baseball’s width from the edge of the zone). Both of those numbers were the highest rates we’d seen since the start of the pitch tracking era in 2008, and both of those numbers were surpassed in 2025, when for the first time ever, more pitches hit the strike zone than missed it. Across baseball, the ideal zone rate has increased.

Below is an analysis of the prospects in the farm system of the Philadelphia Phillies. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the sixth 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.

The San Francisco Giants, with their unique front office leadership and unconventional manager, have gone the traditional route. “Acquire Harrison Bader” is a tried-and-true team-building strategy for a would-be contender; the former Florida Gator is on his way to his seventh organization in the past four-and-a-half years.

The Giants, unlike Bader’s previous employers, seem interested in keeping him around long enough to unpack all his furniture: Bader’s new contract is for two years and $20.5 million.

Regardless of any analysis to follow, this move makes the Giants stronger in 2026. Bader is a legitimate center fielder who’ll relieve the defensive pressure on the freshly emancipated Jung Hoo Lee (who’s stretched in center) and Heliot Ramos (who’s stretched at any position that requires him to wield a glove). Guys who can play center field comfortably and have a clue at the plate are harder to find than you’d think — especially in free agency — and the Giants got one. Read the rest of this entry »

One day, José Ramírez will get old. One day, he’ll dodder out to the grass in front of the pitcher’s mound on the arm of an adorable grandchild and lollipop the ball into the dirt in front of home plate to the warm cheers of the Cleveland faithful. That’s sure to happen at some indeterminate point in the future. This weekend, however, the Guardians expressed their belief that Ramírez’s inevitable decline is a long way off, inking the 33-year-old future Hall of Famer to a seven-year contract extension that will keep him in the fold through the 2032 season. When the extension expires, Ramírez will be 40.

We’ll break down all the numbers and the dollars, but the biggest story here is the most obvious one. This is great news for anybody who loves Ramírez, the Guardians, or baseball. Ramírez has full no-trade rights, and there’s every reason to expect him to stay for the rest of his career. It’s time to talk about statues and plaques and how nice it is that we’ll never have to know just how wrong it would feel to see him in a jersey that doesn’t say Cleveland on it. This is the third extension Ramírez has signed. The first came in 2016, and it bought out his arbitration years plus two option years. The second came in 2022, and, like this one, it bought out the final three years of the previous extension. Ramírez wanted to stay in Cleveland, and with those first two extensions, he forfeited tens of millions of dollars on the open market to do so.

This extension is slightly more complicated, and the details matter quite a bit. Ramírez was already signed though the 2028 season as part of the previous seven-year extension, so it’s not as if there was a pressing need to get this done. He was owed $69 million over the next three years. This deal reworks his compensation over that period and adds four more years. Over the next seven seasons, Ramírez will earn $25 million per year, with $10 million per year deferred. (Each of those deferrals lasts 10 years, and then pays out $1 million per year for 10 years. So he’ll get $1 million in 2036, $2 million in 2037, and so on until he gets his final $1 million payment in 2051.) The deal also came with perks like increased bonuses for awards and high finishes in the MVP voting, an extra hotel room on road trips, and use of a private jet to and from the All-Star Game plus one extra time per year.

Joe Boyle is emerging as a late-bloomer success story. Now 26 years old, the Tampa Bay Rays right-hander is coming off a campaign during which he not only continued to display a power arsenal, but began to rein in his command as well. Over 86 innings with Triple-A Durham, Boyle paired a 32.9% strikeout rate with an 11.8% walk rate; across 52 innings with the big league club, those numbers were 25.7% and 12.4%. While admittedly far from George Kirby-esque, those free-pass percentages were nonetheless a meaningful step in the right direction.

Boyle’s relationship with the strike zone has long been tenuous. In May 2024, Eric Longenhagen wrote that while “Boyle has had huge stuff for his entire life as a prospect, [he has] also been very wild.” Fast forward to December of that same year, and our lead prospect analyst again cited the nastiness of the 6-foot-8, 250-pound hurler’s offerings, adding a caveat that he has “zero feel for location.”

Something else that Longenhagen wrote 13 months ago bears noting:

“It’s possible that the Rays will attempt to do with Boyle what they successfully accomplished with Tyler Glasnow: Simplify his delivery to make it more consistent and hope it’s enough for him to be a five-inning starter.”

Currently projected as the Rays’ fifth starter by RosterResource, Boyle is now with his third organization. Selected in the fifth round of the 2020 draft by the Cincinnati Reds out of the University of Notre Dame, he was subsequently swapped to the Oakland Athletics in 2023, and then to Tampa Bay the following winter. It is understandable that the pitching-savvy Rays were, and remain, enamored with his potential. While Boyle’s success at the major league level has been spotty — his ERA last season was 4.67 — his comps stick out like a sore thumb. Baseball Savant’s list of the pitchers most similar to Boyle based on velocity and movement comprises Chase Burns, Jacob deGrom, Dylan Cease, Hunter Greene, and Bubba Chandler.

You already know how it works: January is for signings, trades, and articles that grade those signings and trades. Everything gets a letter, every transaction has a winner and loser, and positive thinkers like me hand out thumbs up left and right. I’ve rarely seen a signing I didn’t like. I think that most trades help out both sides. What about the aggregate effect of all the signings and trades, though? Which teams play the offseason game the best or the worst? Looking at the Mets this winter got me thinking.

How should we evaluate a front office, particularly in the offseason when we don’t have games to look at? I’ve never been able to arrive at a single framework. That’s only logical. If there were one simple tool we could use to evaluate the sport, baseball wouldn’t be as interesting to us as it is. The metrics we use to evaluate teams, and even players, are mere abstractions. The goal of baseball – winning games, or winning the World Series in a broad sense – can be achieved in a ton of different ways. We measure a select few of those in most of our attempts at estimating value, or at figuring out who “won” or “lost” a given transaction. So today, I thought I’d try something a little bit different.

Instead of a single number, I’m going to evaluate the decisions that David Stearns and the Mets made this winter on three axes. The first is what I’m calling Coherence of Strategy. If you make a win-now trade but then head into the season with a gaping hole in your roster, that’s not coherent. If you trade a star for teenage prospects and then extend a 33-year-old, that’s not coherent. Real-world examples are never that simple, but you get the idea. Some spread in decisions is inevitable, but good teams don’t work against themselves more than they have to.

Next, Liquidity and Optionality. One thing we know for sure about baseball is that the future rarely looks the way we expect it to in the present. Preserving an ability to change directions based on new information is important. Why do teams treat players with no options remaining so callously? It’s because that lack of optionality really stings. Why do teams prefer high-dollar, short-term contracts over lengthy pacts in general? It’s because you don’t know how good that guy is going to be in year six, and you certainly don’t know how good your team will be or whether you’ll have another player for the same position. All else equal, decisions that reduce future optionality are bad because they limit a team’s ability to make the right move in the future.

Finally, maximizing the Championship Probability Distribution. We like to talk about teams as chasing wins, but that’s not exactly what’s going on. Teams are chasing the likelihood of winning a World Series, or some close proxy of that. That’s often correlated to wins, but it’s not exactly the same. Building a team that outperforms opponents on the strength of its 15th-26th best players being far superior to their counterparts might help in the dog days of August, when everyone’s playing their depth pieces and cobbling together a rotation, but that won’t fly in October. Likewise, high-variance players with decent backup options don’t show up as overly valuable in a point estimate of WAR, but they absolutely matter. Teams are both trying to get to the playoffs as often as possible and perform as well as they can after arriving there. That’s not an easy thing to quantify, but we can at least give it a shot.

Let’s begin with a look at the transactions that reshaped the lineup. The biggest of these has to be the infield turnover, with Pete Alonso out and Bo Bichette, Jorge Polanco, and Marcus Semien in. Since we’re including Semien, we’ll have to include the departure of outfielder Brandon Nimmo as well. These decisions are clearly coherent; Alonso’s leaving meant space in the infield and an offensive deficit, and the Mets signed multiple free agents to account for that. I’ll analyze the Coherence of Strategy axis at the end of this write-up, but for each individual deal, I’ll focus on the other two axes of analysis.

Last week, the White Sox admitted defeat in their handling of Luis Robert Jr.’s contract, shipping him out to the Mets for two lottery tickets and salary relief. That salary relief must have been burning a hole in their pocket, though. Or perhaps someone looked at their books, said “Guys, we play in Chicago but we’re projected for the lowest payroll in baseball and people are going to talk,” and handed GM Chris Getz a list of players who hadn’t yet signed. In any case, Seranthony Domínguez and the White Sox have agreed to terms on a two-year deal worth $20 million, as ESPN’s Jeff Passan first reported.

The right-handed Domínguez is no stranger to high-pressure relief work. In both the 2022 and 2023 postseasons, he appeared in mid- and high-leverage situations for the Phillies, and he handled them quite well (1.13 ERA, 0.78 FIP in 16 innings). In 2024, Philadelphia didn’t have much use for his services after his slow start, and so they sent him and Cristian Pache to the Orioles for platoon bat Austin Hays (whom they promptly non-tendered after the season). The O’s employed Domínguez for a year (he made two appearances for them in the playoffs), then dealt him and cash to the Blue Jays in exchange for Juaron Watts-Brown, a 40-FV relief prospect. He pitched for the Jays in October, and memorably had some ups and downs in their long run.

In other words, playoff teams have been employing Domínguez for years, but they haven’t been placing particularly high importance on his performance. He’s twice been traded to contenders in deadline deals, and at no point did his suitors offer much to get him. Those teams considered him a mid-leverage option; even the Blue Jays had him as a second-tier option out of their weak-link bullpen that flailed its way through October.

This year’s Hall of Fame ballot included three former Philadelphia Phillies position players, none of whom received the necessary 319 votes (out of 425 cast) to gain election. Chase Utley fared best with 251 votes (59.1%), while Bobby Abreu got 131 (30.8%), and Jimmy Rollins received 108 (25.4%). As did my colleagues Jay Jaffe and Dan Szymborski, I put checkmarks next to Abreu’s and Utley’s names, but not Rollins’s.

How did other BBWAA voters choose among the Phillies trio? A comprehensive answer isn’t possible — not everyone makes their ballots public — but we do know about the 260 voters whose selections were shared on Ryan Thibodaux’s Ballot Tracker. Here is the breakdown as of yesterday afternoon courtesy of the Tracker’s Anthony Calamis:

66 voted for none of the three.
25 had all three.
52 had only Utley.
9 had only Abreu.
3 had only Rollins.
63 had Utley and Abreu, but not Rollins.
42 had Utley and Rollins, but not Abreu.

As for the players’ relative merit, that is in the eye of the beholder. Reasonable arguments, both for and against, can be made for all three former Phillies by prioritizing specific statistics and accolades — or even reputations (none of Abreu, Rollins, or Utley have been tainted by scandal).

At this time last week, the Mets were celebrating their signing of Bo Bichette. Up until that point, though, their offseason was largely being viewed as a letdown as they assembled an oddly shaped roster. Earlier this winter, they watched as Edwin Díaz spurned them for the Dodgers, let Pete Alonso walk and then signed Jorge Polanco to play first base, and missed out on Kyle Tucker. Sure, they upgraded at second base with the Marcus Semien trade, but doing so required them to part with Brandon Nimmo, who was coming off a year in which he hit a career-high 25 home runs and posted 3.0 WAR. They decided to replace that production with 23-year-old Top 100 prospect Carson Benge, who had a 53 wRC+ in 103 Triple-A plate appearances last season, as the big spoon of a platoon in left field. They also reinforced their bullpen with two of the more inconsistent members of the 2025 Yankees’ relief corps, Devin Williams and Luke Weaver. These weren’t bad moves, to be clear. Williams especially is a strong bounce-back candidate; Polanco is a quality player, though his entire experience at first base consists of one defensive plate appearance; and Semien fulfills the team’s desire to get better defensively. But they were a bit puzzling given that the Mets’ greatest areas of need were another impact bat, a center fielder, and a frontline starting pitcher.

As it turns out, adding Bichette was just the first in a trio of acquisitions to address those major roster holes. Late Tuesday night, the Mets traded for center fielder Luis Robert Jr., who is coming off two straight seasons of injuries and poor performance but is still a tantalizing talent and just 28 years old. “If you made an outfielder in a lab, he’d look a lot like this,” wrote Ben Clemens about Robert after the trade. Then, on Wednesday, they swung a swap with the Brewers for All-Star right-hander Freddy Peralta to anchor their rotation. They had to give up two of their top prospects to get him, but as Davy Andrews noted in his column on the trade, “the Mets are trying to win this season, and now that he’s not in Milwaukee, David Stearns has the luxury of leaving tomorrow’s problems for tomorrow.”

We won’t be answering any questions about the Mets or any of the other big recent transactions, such as Cody Bellinger’s re-signing with the Yankees or the Rangers’ trade for MacKenzie Gore, but we will be talking about the other big baseball topic of the week: the Hall of Fame. We’ll also discuss the best left-on-left hitters of all time, the aesthetic potential of the Colorado Rockies, and what to expect from Foster Griffin with the Nationals.
