Konnor Griffin Will Be a Pirate For a Very Long Time

Charles LeClaire-Imagn Images

I’m a fan of gallows humor, and I think that fans of the Pirates need to be as well. The Pirates have developed their share of stars over the years, but for fans, there’s always the slight bit of dread that once their young talent starts getting paid commensurate with their production, they’ll be swapping the black-and-gold for Dodger blue or pinstripes. So it’s a good time for Yinzers and the Allegheny-adjacent community, as shortstop Konnor Griffin and the team agreed to a nine-year, $140 million contract that would keep him in town until after the 2034 season.

As contracts go, this is a rather straightforward one. While MVP incentives can bring up the deal by a modest $10 million, to $150 million, that’s just about the only complexity present. There is no deferred money to eat away at the present value of the contract, no option years for the Pirates to lock in at the end, and no opt-out provision that could get Griffin to free agency a year or two early. The deal includes a $12 million signing bonus, which will be doled out over the next three years, certainly helpful to Griffin in that he’ll still get a nice chunk of cash even if the seemingly inevitable lockout drags into the 2027 season.

The Pirates have a real up-and-down history with contracts, so it’s always nice to see them spend on franchise talent rather than spread things around on third-tier free agents. They managed to keep Andrew McCutchen a few years past his free agent eligibility, but for the last 50 years, most of the stars who started out in Pittsburgh became better associated with other teams. Players ranging from Barry Bonds and Bobby Bonilla to Aramis Ramirez and Gerrit Cole, a group that could include Paul Skenes in a few years. Some of the deals the Pirates did sign haunt the dreams of Gen X and millennial Pirates fans (Pat Meares! Kevin Young! Derek Bell!). The Pirates signed Andy Van Slyke and paid him more than the Giants paid Bonds during the latter’s first years in San Francisco.

Griffin was basically everyone’s top-ranked prospect coming into this season, and it’s not hard to see why. He has more tools than can be found at a Florida spring break kegger, and in his first professional season, he terrorized minor league pitchers to the tune of a .333/.415/.527, 165 wRC+ line across three levels, including a 175 wRC+ in his month at Double-A. That would be a drool-worthy performance if he were a 23-year-old first baseman, but he did all of that as a teenage shortstop. He still doesn’t hit the big two-oh for a couple of weeks. Griffin’s one of the few prospects you can plausibly compare to A-Rod at a similar stage in his career without the listener rolling their eyes and saying, “Who, Aurelio?”

A few weeks ago, I did my annual look at contracts I’d like to will into existence, and ZiPS suggested an eight-year, $142 million contract for Griffin. So getting a ninth year is even better!

2034 .270 .349 .446 596 118 161 29 2 24 111 50 139 25 119 5.8

That ninth year is pretty darn valuable, and ZiPS would be quite happy to give Griffin $40 million more in order to secure the 2034 projection. ZiPS, like most projection systems, does not generally have fits of irrational exuberance, for the simple fact that it’s well aware about how risky players are. Griffin is not a 5-WAR player yet, so there is risk involved, but that’s true of all players, whether they’re elite prospects or superstars in the middle of their careers. Albert Pujols and Miguel Cabrera were obviously far more “proven” when they signed their biggest deals than Griffin is now, but the Angels and Tigers paid handsomely for that so-called proof, and as should be clear now, there was a lot of downside involved there, too.

A $140 million contract isn’t a mega-deal in the typical baseball sense, but for the Pirates, Griffin’s contract represents the biggest financial commitment they’ve ever made to a player. They’re all-in when it comes to the Konnor Griffin business. Both team and player are now spared things like years of speculation about future trades or service-time games should Griffin struggle in April. Remember the time the Pirates offered Gerrit Cole $538,000, and when he turned it down, they apparently wouldn’t budge past $541,000, and threatened to pay him the league minimum if he refused? Cheap-bush league shenanigans are now out of the question with Griffin, and the focus can be on the actual baseball.

Even if Griffin isn’t immediately a megastar, he makes the Pirates meaningfully better, and they know it. He really did look raw at times in the spring, to the level that sending him down was excusable, even understandable, unlike when the Chicago Cubs in 2015 decided they needed precisely 20 days some additional time to figure out if Kris Bryant was a better option at third base than Mike Olt. Griffin did get five games with the Triple-A Indianapolis Indians, and it certainly looked like, in a small sample size, that he wasn’t really anything new against minor league pitching. But that’s not the point. The Pirates are true NL Central or Wild Card contenders, and they are much better off with Griffin as their starting shortstop, even if it takes him some time to adjust to the majors, than a decent role player like Jared Triolo. (Triolo has since been placed on the injured list with a patellar tendon injury in his right knee.)

With the long-bubbling Griffin contract negotiations finally complete, now the Bucs can worry about the rest of the team, and making the Cubs and Brewers feel uncomfortable for the rest of 2026.

It would border on being grotesquely premature to talk in too-concrete terms about a 19-year-old Griffin and the possibility of him one day having a Hall of Fame plaque in Cooperstown. But at least if such an object should ever come into existence, there’s now a realistic chance that it could have a “P” on the cap. That’s enough to make this a good week for Pirates fans.


Trio of Playoff Contenders Each Loses Superstar to Injury

Robert Edwards, Rick Scuteri, Thomas Shea-Imagn Images

Until this weekend, baseball’s injured list was noticeably bare to start the 2026 season. Then, beginning with Blue Jays catcher Alejandro Kirk on Friday, the stars went down in rapid succession. The Cubs lost two of their top starting pitchers, Cade Horton and Matthew Boyd, in consecutive days. Joining them on the IL are two of the top players in the National League, Mets left fielder Juan Soto and Dodgers shortstop Mookie Betts, and one of the best pitchers in the American League, Astros ace Hunter Brown. Each of those three teams has a share of first place at the moment, making these especially high-leverage injuries. Read the rest of this entry »


Yes, Pennants Can Be Lost in April

Katie Stratman-Imagn Images

When looking at most April stats, especially the basic ones, I spend a lot of time issuing disclaimers about small sample sizes. After all, any player can do just about anything in 25 or 50 or 100 plate appearances. I’m pretty confident that Joey Wiemer is not going to end the season as the NL MVP, and that Hunter Barco won’t finish the season with the worst WAR in major league history. But conversely, when we’re talking about standings, even if bad/good starts shouldn’t necessarily overconcern us about a player’s future, when it comes to teams, playoffs are determined by wins, which are cumulative numbers with razor-sharp margins. It’s not the end of the world if Cal Raleigh, because of his slow start, finishes with 38 homers instead of his projected 41 (ZiPS DC), but it may doom the Mariners if they underperform their projections by three wins.

The season is just a week old, but there are already sizable impacts in playoff probabilities around the league. To demonstrate this, I ran ZiPS overnight to get the updated playoff odds, so I could compare them to the preseason projections. Six teams have seen their playoff odds change by at least five percentage points. Here’s the full table, as things stand on Friday morning.

Mariners, Top Prospect Colt Emerson Agree on $95 Million Contract

Mark J. Rebilas-Imagn Images

Apparently not wanting to be left out of the flurry of contract extensions handed out over the last two weeks, the Seattle Mariners signed a big one of their own, locking up infield prospect Colt Emerson to an eight-year contract that guarantees him $95 million over the next eight years. This includes a $1 million salary for 2026, meaning that the contract goes through the end of the 2033 season, with the Mariners holding a 2034 club option that could staple another $25 million onto the back of the contract. Emerson’s deal also includes a no-trade clause and bonuses for All-Star selections and Silver Slugger and MVP awards, de rigueur in deals such as this.

Emerson, who doesn’t turn 21 until July, is widely considered Seattle’s top prospect by most sources, whether you prefer our prospect team, Keith Law over at The Athletic, old friend Kiley McDaniel at ESPN, Baseball Prospectus, Baseball America, or mean ol’ ZiPS. That’s no small feat to pull off when you’re in the same organization that has high-end pitching arms like Ryan Sloan and Kade Anderson.

While Emerson doesn’t have one mind-blowing tool that absolutely obliterates the cognitive pathways of watchers, he’s very accomplished at basically everything he does. He’s not going to regularly blast Stantonian shots, but he’ll hit his fair share of home runs, ZiPS thinks 15-20 a year if he played home games at a neutral site rather than T-Mobile Park. Emerson is willing to draw walks, but he still retains a fundamental aggression at the plate; that’s a good thing, as being too passive is a frequent pitfall for prospects who take a good amount of free passes. There’s no whiff problem hiding in his advanced stats, either. He’s not a burner on the basepaths like Trea Turner or Bobby Witt Jr., but at the same time, he’s not me with a belly full of Cool Ranch Doritos, a 32-ounce deli container of beer, and a hamstring that hasn’t gotten a whole lot of use since the Clinton administration. It doesn’t seem like there are any serious concerns about his sticking at shortstop, and the coordinate-based method that ZiPS uses for minor leaguers sees him as a solid B+ defender at the position. Let’s crank out those projections. Read the rest of this entry »


The Official (And Hopefully Not Too Erroneous) 2026 ZiPS Projected Standings

Kiyoshi Mio-Imagn Images

And just like that, the end of winter has been heralded, not by a groundhog or the vernal equinox, but by 6 1/3 shutout innings by Max Fried last night at Oracle Park. Today is the official Opening Day in MLB, and as such, it’s time for the ZiPS projections to spit out its final preseason projections. Hopefully, its numbers are graceful and kind, just in case it has to eat them in six months. This is the 22nd such exercise I’ve done with the ZiPS projections, and as with the other 21 times, there’s not much to do but sit back and wait for reality to destroy the expectations. Most of you already know the methodology by now, but for those who don’t, I’ll do a quick rundown. The rest of you can skip straight to the reason you’re here: the standings!

The ZiPS projected standings are the results of a million simulations of the 2026 season, using the ZiPS projections and the actual team schedules. The methodology isn’t identical to the one we use for our playoff odds. So how does ZiPS calculate the season? Stored within ZiPS are the first- through 99th-percentile projections for each player. I start by making a generalized depth chart, using our Depth Charts as a jumping off point. Since these are my curated projections, I make changes based on arbitrary whimsy my logic and reasoning. ZiPS then generates a million versions of each team in Monte Carlo fashion. These projections do reflect the updated post-spring training projections, which were added to the FanGraphs database on Wednesday afternoon. Read the rest of this entry »


Szymborski’s 2026 Booms and Busts: Pitchers

Vincent Carchietta and Brad Penner-Imagn Images

When you run a lot of projections, one thing you have to get used to is being very wrong, very often. The ZiPS projections generally run about 4,000 players every year, meaning you should expect around 800 players to either achieve their 90th-percentile projection or fall short of their 10th-percentile projection. Those hundreds of results will invariably be quite a distance away from the standard midpoint projections that you see.

As is my ritual, it’s time to run my two articles discussing my favorite booms and busts of the upcoming season. After looking at the hitters last week, today we turn our attention to the pitchers. But just to keep the ritual of humiliation fully transparent, we’ll start by looking at the pitchers I selected for last year’s booms and busts.

Szymborski’s 2025 Boom Pitchers
Player ERA FIP ERA- WAR
Jack Leiter 3.86 4.15 95 2.3
Spencer Schwellenbach 3.09 3.56 73 2.4
Brandon Pfaadt 5.25 4.22 123 1.7
Zebby Matthews 5.56 3.79 135 1.4
James McArthur NA NA NA 0.0
Graham Ashcraft 3.99 2.72 90 1.6
Caden Dana 6.40 6.48 154 -0.4
Ian Hamilton 4.28 4.39 106 0.0

Szymborski’s 2025 Bust Pitchers
Player ERA FIP ERA- WAR
Jacob deGrom 2.97 3.64 74 3.4
Javier Assad 3.65 4.24 88 0.3
Luis Castillo 3.54 3.88 92 2.6
Jackson Jobe 4.22 5.18 103 0.1
Alexis Díaz 8.15 8.51 189 0.6

Thank goodness I was wrong about Jacob deGrom, as he managed to have his first essentially healthy season in forever! I think it’s finally time for me to get off the Brandon Pfaadt train, meaning he’ll probably have his breakout this year. A real mixed bag, but it was overall a less bleak result than I had with the hitters! Read the rest of this entry »

When you run a lot of projections, one thing you have to get used to is being very wrong, very often. The ZiPS projections generally run about 4,000 players every year, meaning you should expect around 800 players to either achieve their 90th-percentile projection or fall short of their 10th-percentile projection.

As is my ritual, it’s time to run my two articles discussing my favorite booms and busts of the upcoming season, starting with the hitters today and concluding with the pitchers next week. But just to keep the ritual of humiliation fully transparent, we’ll start by looking at last year’s booms and busts.

Oof, ritual humiliation indeed! The booms did not pan out well in 2025, even if you give me generous credit and mark my picks of Joe Mack and Gage Workman as incomplete. The busts worked out much better — from my point of view, at least — but it’s a lot less fun to be right about the bad stuff.

2026 Positional Power Rankings: Shortstop

Jerome Miron-Imagn Images

I’m somehow nearing 50 years of age — I’m a little concerned this number seems to be going up by one every 365 days or so — and the position of shortstop has changed a lot since I got into baseball as a small child. Back then, the attitude was defense is what mattered from shortstops, and anything else a team got from the position was gravy. In 1978, the year I was born, only four primary position shortstops with 300 plate appearances had a wRC+ of at least 100: Roy Smalley III, Dave Concepcion, Robin Yount, and the eternally underrated Toby Harrah. Only Smalley and Harrah even hit the double digits in home runs. In 2025, 25 primary position shortstops had double-digit home run totals and 19 finished with a wRC+ in the triple digits. An average player at the position in 1978 slashed .258/.309/.335, a line that would cause teams of today to look for an upgrade unless their shortstop were Ozzie Smith with the glove.

While there were always scattered shortstops who excelled at the plate, they were generally seen as outliers. But that changed as teams became more and more willing in the 1980s and 90s to let their best athletes stay at shortstop until they conclusively proved they shouldn’t be at the position, and larger players like Cal Ripken Jr. and Alex Rodriguez weren’t simply moved to traditional “big dude” positions. Defense remained important, but offense became a really big deal, as many talented hitters demonstrated that previous generations were too quick to move young sluggers down the defensive spectrum. Shortstops are like quarterbacks now; you either have a star shortstop or you’re biding your time until you find one. Read the rest of this entry »


The Doomsday Scenarios

Eric Hartline and Thomas Shea-Imagn Images

I’ve now spent nearly a quarter of a century working with baseball projections, and in that time, I’ve always been struck by the certainty with which so many people view them. People are far more certain than they should be that great teams will be great, star players will be stars, and so on. However, one of the things that comes from working with projections for a big chunk of your life is that you develop a painful awareness of how much of the future cannot be known until it actually happens.

As in most seasons, we enter without a general conception of which teams will be the best. We may pretend everyone starts off with a clean slate, but absolutely nobody expects the Rockies to be better than the Dodgers. But even if that particular scenario is extremely unlikely, every one of the top teams has a scenario in which things fall apart. These clubs have a vested interest in protecting against that potential downside, as much as possible, so I thought it would be interesting to look at the doomsday scenario for some of the best teams in baseball.

To get an idea, I did a full seasonal simulation of the ZiPS projected standings, and instead of looking at the standings overall, I looked at the bottom 20% of outcomes to see what we could glean from the results. According to ZiPS, every team except the Dodgers misses the playoffs when it performs no better than its 20th-percentile win total.

Philadelphia Phillies: Rotation Depth

This almost seems counterintuitive given just how good the rotation projections are for the Phillies, but the projections are not enthusiastic about their depth here. And what makes that especially worrisome is that with so much uncertainty around the health of Zack Wheeler and the performance of Aaron Nola, Philadelphia is probably going to need that depth more than it did last year. This time around, the Phillies are missing Ranger Suarez, who signed with the Red Sox during the offseason. Andrew Painter was healthy in 2025, but one cannot ignore that he was rather middling against Triple-A hitting. The outfield looks like a problem, as well, but it generally has been, and ZiPS is a fan of Justin Crawford.

If Philadelphia adds one of the innings-eaters still available in free agency, ZiPS sees the team’s outlook improve, much more than I expected. Just having someone like Lucas Giolito, Tyler Anderson, or even Patrick Corbin around did a lot to alleviate the rotational downside. It may come down to which of these pitchers is open to a swing role or a minor league deal with an opt-out date. And yes, I do think it feels weird to suggest Corbin as an upgrade for a team in 2026.

New York Mets: Right Field

The Mets certainly don’t dominate in either the rotation or bullpen projections, but ZiPS is fairly confident that both of these units will hold up over the course of the season. Despite a solid projection for Carson Benge in right field, the range of outcomes is quite high, and in the simulations where Benge struggles, ZiPS has trouble competently filling in right field. Tyrone Taylor is an underwhelming option, and ZiPS thinks Brett Baty would have a tough time defensively in the outfield. With no particularly interesting outfielders available in free agency, the best solution might simply be making sure Jacob Reimer gets some time in the outfield. New York’s roster just isn’t really set up to get him time at third base, where he probably is most valuable. But he also represents the most tantalizing 2026 upside of any player the Mets have in the minors, so they ought to try and be open to promoting him aggressively, and getting a little weird with it, if need be.

New York Yankees: Injuries

The Yankees’ outcomes are weird, in that their bad seasons were mostly ones in which Aaron Judge, for whatever reason, ended up with fewer than 300 plate appearances, and only occasionally something else. Getting limited innings from Gerrit Cole and Carlos Rodón was already baked into the cake, and ZiPS thinks there are enough fourth-starter types to patch up any rotation holes that might pop up. The problem is, just how do you replace Judge? I’m not sure there’s a scenario where the Yankees can do much to mitigate any risk there, for the simple reality that in a tightly projected division, suddenly losing six wins is likely to drop them out of the AL East divisional race. At the very least, the Yankees should hold off on shopping Spencer Jones for help elsewhere, but it wouldn’t fix a Judge loss.

Baltimore Orioles: Rotation Quality

Baltimore has potential aces in both Trevor Rogers and Kyle Bradish, but that word potential is an unpleasant adjective. Adding Pete Alonso and Taylor Ward really stabilizes the offense, which was a concern last year, but the rotation is an issue. The Orioles finished with a bottom five rotation in the ZiPS simulations more often than all other AL East teams combined. There’s nothing on the farm that helps this, and I think that with the Orioles increasingly pushing their chips in, they ought to be aggressive at taking the opportunity to loot struggling teams of their top pitching, even if the prospect hit would be tremendous. I think there are even scenarios, though not many, in which it might make sense for the O’s to trade either Adley Rutschman, assuming he has a bounce-back season, or Samuel Basallo.

Boston Red Sox: First Base

The good news is that ZiPS sees the Red Sox as the most stable of AL contenders, with the lowest percentage of sub-.500 seasons of any AL team. The rotation isn’t the best in baseball, but it may be the most bulletproof one, and that isn’t even counting on getting lots of innings from pitchers like Payton Tolle and Connelly Early, who would be Plan As in most rotations in baseball. In fact, when the Red Sox had their worst performance, it was almost entirely the offense that fell short, and not necessarily from the position you might expect.

Most people have focused on third base because of the loss of Alex Bregman, but Caleb Durbin is actually a decent option. Plus, if Durbin struggles, Marcelo Mayer could very likely provide what the former isn’t. Where there is real downside risk is at first base. I liked the Willson Contreras acquisition, too, and he’s probably going to be at least solidly average in 2026, but he’s also going to be 34 in May. It’s an age where you look at the long left tails of the outcome distribution for non-elite first basemen, and there’s always a real risk of a very sudden plummet off a cliff. Triston Casas hasn’t played in a game since last May — and won’t even play in any spring training games this year — and he has a real mixed history.

What to do? That’s a lot trickier. Boston obviously isn’t going to replace Contreras before he has that downside year. But this team should be ready for that possibility, and if the surplus of pitching turns out to be real, the Sox will have a position of depth from which to trade.

Chicago Cubs: Rotation Quality

The outlook improved with the addition of Edward Cabrera, but ZiPS still has the Cubs with the weakest rotation of the 10 teams listed here. In the ZiPS simulations, the rotation was largely the source of the Cubs’ worst seasons. There aren’t really any exciting starters left out there in free agency, but I think I’d do what I suspect the Cubs are already thinking of doing: giving Ben Brown’s upside as a starting pitcher more serious consideration. He allowed too many home runs and had a high BABIP on a really good defensive team, but it’s guys like that who tend to come out of nowhere quickly (see Corbin Burnes in 2019). Brown has swing-and-miss stuff, and I think given the potential, I’d rather see him starting at Triple-A than pitching in relief in the majors.

Houston Astros: Outfield Corners

Not counting 2020, for obvious reasons, the 686 runs the Astros scored in 2025 represented their fewest since 2014. A full, healthy season of Yordan Alvarez would be incredibly helpful, but the team’s also not likely to wring another 135 wRC+ out of Jeremy Peña. Not helping matters is that Joey Loperfido and Cam Smith project as one of the weakest corner outfield tandems in the majors in 2026. Smith surprised many, including me, in the early months last year, but an OPS that fell shy of .500 in the second half is highly concerning. There’s a chance that the Astros get little from their outfield corners, which is a problem for a team with a middling offense that just lost ace Framber Valdez in free agency. In some 30% of simulations, the Astros got a sub-90 wRC+ out of their corner outfielders, and in those runs, they had a .475 winning percentage. If there’s a team that should aggressively go after either Jarren Duran or Wilyer Abreu, it’s Houston.

Toronto Blue Jays: Rotation Depth

Even with the loss of Anthony Santander to shoulder surgery, ZiPS still sees the Blue Jays’ rotation as their biggest pain point. There are simply a lot of question marks once you get past Dylan Cease and Kevin Gausman, something I mentioned a bit in Toronto’s ZiPS rundown in January. In a lot of the sims, the team got next to nothing out of any of Cody Ponce, José Berríos, Shane Bieber, and Max Scherzer, whether because of injury, decline, or general performance issues. If Sandy Alcantara looks anywhere near his old self with the Marlins in the early months, I think the Jays ought to be one of his suitors. At the very least, Alcantara would do well with an infield that has Andrés Giménez and Ernie Clement.

Seattle Mariners: Outfield Corners

As with the Astros, ZiPS sees Seattle’s corner outfield spots as having the most downside. Unlike the Astros, ZiPS doesn’t view it as truly a doomsday scenario. After the Red Sox and Dodgers, ZiPS considers the Mariners to be the contender with the least downside. Randy Arozarena’s projection distribution is pretty interesting, with the bottom falling out of him once you get under the 15th-percentile projection or so; while his 20th-percentile OPS+ is a non-disastrous 94, it drops to 70 for the 10th-percentile level. As for Victor Robles, he’s been all over the place in his career, and the Plan Bs in the organization are unimpressive. I think Seattle’s strong enough that it doesn’t necessarily have the same need to be aggressive as Houston does, but this is still a potential point of weakness that could pose an issue.

Los Angeles Dodgers: Black Swans

It’s really hard to kill the Dodgers. I argued after the 2024-2025 offseason, a very busy one, that the Dodgers weren’t really improving their average outcome so much as drastically raising their floor. I stand by it; they’ve added Kyle Tucker and Edwin Díaz while losing nobody who was crucial to the 2025 team. That doesn’t mean they’re going to be projected to win 105 games or anything, but it does mean that in most of their worst projected outcomes, they’re still a playoff contender. Their 10th-percentile projection, for example, is 86 wins. Their 2% chance of finishing below .500 is the smallest percentage I’ve ever projected, a record that now goes back more than 20 years. Doomsday for the Dodgers may require an actual doomsday scenario like societal collapse, nuclear war, or a vacuum metastability event. Since I do not know how to prevent any of those, there’s nothing more I can add.
