The St. Louis Cardinals, or what’s left of them, have traded third baseman Nolan Arenado and cash to the Arizona Diamondbacks for right-handed pitcher Jack Martinez.

Arenado was one of the best players of the 2010s, a three-time National League home run champ and an elite defensive third baseman. In eight seasons with the Rockies, Arenado made five All-Star teams and finished in the top eight in MVP voting five times. He made the All-Star team and pulled off the Gold Glove-Silver Slugger double every season from 2015 to 2018.

On the strength of those performances, the Rockies signed Arenado to one of the richest contracts in baseball history — nine years, $275 million. After two years, they shipped him to St. Louis, where the Cardinals lived out the bargain of the quarter-billion-dollar extension: A couple great seasons, followed by gradual decline and now decrepitude, all before the deal runs out.

Steven Kwan looks like the kind of guy who gets underestimated. He’s undersized. He doesn’t hit the ball particularly hard. He plays for a franchise that’s most famous for refusing to spend money. Still, I don’t think many people are underestimating Kwan these days. He’s the undisputed second-best player on the Guardians, behind only future Hall of Famer José Ramírez. He’s a two-time All-Star. He’s never put up fewer than 3.0 WAR in a season. He’s never not won a Gold Glove. Everybody knows that he’s a great player, but I’d like to highlight a couple specific parts of his game that we tend to take for granted.

Kwan’s defense certainly receives plenty of appreciation. In two of his four major league seasons (2023 and 2025), he has swept the three advanced defensive metrics, finishing first among all left fielders in Defensive Runs Saved, Deserved Runs Prevented, and Fielding Run Value. In 2022, he finished first in both DRS and FRV, but didn’t lead in DRP. In 2024, he finished in second in FRV and fourth in DRS (but because of the arguably arcane innings minimum of 900, he did lead all Gold Glove-eligible left fielders in both metrics). The point of this complicated litany is that all of the major defensive metrics love Kwan, and that’s important because they use very different methods, methods don’t always line up. DRS detests Oneil Cruz, but FRV thinks he’s great. DRP loves Randy Arozarena even though the other two systems hate his guts. All the systems can agree on Kwan. Whether you’re breaking down video with human eyes or analyzing catch probability through the lens of a high-speed Statcast camera, when you look at Kwan, you’ll see the best left fielder in the game.

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:

The baseball industry loves its pitching prospects — and sometimes seems to love dreaming on them by using them as trade chips almost as much as it does actually letting them pitch. Considered to have one of the best curveballs in the game from the outset of his professional career, Gio Gonzalez was traded three times before he’d thrown a major league pitch, and five times during a career that ended just after he turned 35. Along the way, the undersized southpaw made two All-Star teams, received Cy Young votes twice, and helped his teams reach the playoffs five times. While he wasn’t always easy to watch given his high walk rates, his ability to miss bats was a testament to the quality of his stuff.

…

Giovany Aramis Gonzalez was born on September 19, 1985 in Hialeah, Florida, a city in Miami-Dade County where roughly three-quarters of the population is of Cuban ancestry. He’s the oldest of six children of Max and Yolanda (Yoly) Gonzalez. Max, a first-generation Cuban-American, installed billboards and owned a scooter shop, while Yoly, an immigrant from Cuba, worked at various jobs to help the family make ends meet.

Gio was just four years old when his parents introduced him to baseball. Growing up, he played sandlot baseball with neighborhood kids in a narrow, rocky strip of land behind the family’s townhouse. “We broke so many windows that I found a guy who would replace them for 15 bucks apiece,” Yoly recalled in 2011.

“Max grew up tough, never got to play as much ball as he wanted and, when it rained on too-rare Sundays when he had a game as a child, he broke down in frustration and cried. But he never stopped studying the sport,” wrote the Washington Post’s Thomas Boswell in 2012. When his eldest son showed an aptitude for the game, Max taught him the curveball that would become his signature. Read the rest of this entry »

Over the weekend, the Chicago Cubs made the splashiest headlines of the new year by signing Alex Bregman — three-time All-Star, two-time top-five MVP finisher, and 2017 World Series champion — to a five-year, $175 million contract. It’s the second-richest contract signed this offseason in terms of total sticker price, and even after accounting for significant deferrals, it’s the second-highest AAV of any contract signed so far this winter.

I don’t want to rehash too much of what Davy Andrews covered in his writeup, but it’s an interesting move to be sure. The Cubs weren’t exactly hard-up for infield help, with Matt Shaw, Dansby Swanson, and Nico Hoerner (from left to right) occupying the three positions Bregman might conceivably occupy. Hoerner’s in his last year of team control, and you might argue that Shaw — my preseason pick for NL Rookie of the Year — disappointed a little in 2025. (I think a 93 wRC+ and 1.5 WAR in 126 games is perfectly OK for a rookie third baseman, though Bregman would likely represent a significant upgrade.)

But for the time being, both incumbents remain in the Cubs organization, leaving a bit of a logjam for manager Craig Counsell to sort out. Nevertheless, I know what the Cubs’ next move should be: Signing Brendan Rodgers. Read the rest of this entry »

For the 22nd consecutive season, the ZiPS projection system is unleashing a full set of prognostications. For more information on the ZiPS projections, please consult this year’s introduction, as well as MLB’s glossary entry. The team order is selected by lot, and the next team up is the Toronto Blue Jays.

Batters

The Toronto Blue Jays were just two runs away from winning the World Series, so suffice it to say, 2025 was a pretty successful season. Even with a disappointing first year from Anthony Santander, the Jays were second in the American League in runs scored. The lineup wasn’t just potent at the plate, either, with the team’s position players leading baseball at 44 runs above average in FRV. The pitching, both the rotation and the bullpen, was fairly middling, but given what Toronto got out of its bats, the arms didn’t need to do that much to propel the team deep into the playoffs. Now the Jays seek to finish 2025’s job in a division that won’t make it an easy task. Not that they’re sitting around and waiting; less than a year after extending Vladito for a half billion dollars, they’ve shelled out another $336 million in guaranteed money this winter. Just for context, that’s nearly $100 million more than the rest of the AL East has spent in free agency combined ($249.6 million). Crashing past the final luxury tax threshold certainly fulfills any reasonable definition of going “all in” on winning.

Neither Andrés Giménez nor Ernie Clement has the offensive upside that the recently departed Bo Bichette does, but both are fine defensive players. ZiPS isn’t banking on Kazuma Okamoto being a star or anything, but he should hit for power and be a plus at third if his defense holds up. Completing the infield is Vladimir Guerrero Jr., and while his offensive output was well below his 2024 level, he was still a star-level first baseman last year. With both Davis Schneider and Addison Barger projected as basically league average starters at second and third respectively, there’s impressive infield depth here as well.

Even though he missed half the season, first recovering from offseason shoulder surgery and then a hamstring malady, Daulton Varsho still managed 2.2 WAR in 2025. Varsho is never going to put up impressive batting averages, but he has very good power for the position and plays good defense, and I think most of the remaining locals who were upset that he’s on the roster instead of Gabriel Moreno have quieted down by this point. The corner outfield positions are both in flux, with the exact mix of Santander and George Springer at DH undetermined, but between those two, Schneider, Barger, and Nathan Lukes, who is more than capable of taking the larger piece of a platoon, they ought to get at least average production in the corners and at DH. The Jays have been endlessly linked to Kyle Tucker, and he’d undoubtedly improve the team, but I’m not sure that they wouldn’t get a lot more bang for the buck by signing one of the top pitchers remaining.

Pitchers

Dylan Cease was a solid addition, and forms a quality 1-2 punch with Kevin Gausman. There’s also a lot of upside in Trey Yesavage — you saw how he pitched in the postseason — and a healthy Shane Bieber could be a big plus. But a pitcher with just a single year of professional experience, or one who comes with Bieber’s injury history, carries real risks as well. Cody Ponce is interesting, and a good risk given the upside, but you can’t completely ignore that before his huge season in the KBO, he really wasn’t very good at all in Japan. If José Berríos gets back on track, well, having too much pitching has never actually been a real problem; the Dodgers over the last five years could tell you about that. I can’t help but think that for as good as the Cease signing was, adding Framber Valdez or Ranger Suárez is still a good idea, as it would lower the rotation’s downside considerably and make the Jays the AL East favorite by a win or two.

Despite the middle-of-the-pack results last year, ZiPS is actually rather enamored with Toronto’s relief corps. While it doesn’t see the team as having a Jhoan Duran or Mason Miller at the top of the ‘pen, with the exception of Yimi García, the computer projects every pitcher with 30 relief innings on our depth chart to have an ERA under 4.00 as a reliever. That even holds true if you stretch things out further, to Chase Lee and Lazaro Estrada. The soft-tossing Tyler Rogers was the big bullpen addition, practically a unicorn in that he’s an exceedingly unusual submariner who doesn’t have significant platoon splits. I don’t think the Jays really need to do much else here, and their deep store of talent might even justify them trading a reliever or two if one of the contenders with bullpen issues fails to shore things up over the next two months.

All told, the Blue Jays look to be neck-and-neck with the Red Sox, and slightly better than the Yankees, in the AL East. As for the Orioles, you’ll have to wait for that ZiPS post later this week.

Ballpark graphic courtesy Eephus League. Depth charts constructed by way of those listed here. Size of player names is very roughly proportional to Depth Chart playing time. The final team projections may differ considerably from our Depth Chart playing time.

Players are listed with their most recent teams wherever possible. This includes players who are unsigned or have retired, players who will miss 2026 due to injury, and players who were released in 2025. So yes, if you see Joe Schmoe, who quit baseball back in August to form a Ambient Math-Rock Trip-Hop Yacht Metal band that only performs in abandoned malls, he’s still listed here intentionally. ZiPS is assuming a league with an ERA of 4.16.

Hitters are ranked by zWAR, which is to say, WAR values as calculated by me, Dan Szymborski, whose surname is spelled with a z. WAR values might differ slightly from those that appear in the full release of ZiPS. Finally, I will advise anyone against — and might karate chop anyone guilty of — merely adding up WAR totals on a depth chart to produce projected team WAR. It is important to remember that ZiPS is agnostic about playing time, and has no information about, for example, how quickly a team will call up a prospect or what veteran has fallen into disfavor.

As always, incorrect projections are either caused by misinformation, a non-pragmatic reality, or by the skillful sabotage of our friend and former editor. You can, however, still get mad at me on Twitter or on BlueSky. This last is, however, not an actual requirement.

Batters

For the first time since 2016, the Houston Astros missed the playoffs. Now, it would be a mistake to call the 2025 season a disaster, as they were just barely squeezed out of October baseball by virtue of an awful idea that I hate with every fiber of my being: the tiebreaker. Still, it’s an unhappy milestone for this era’s Astros, especially coming after the departure of two of the team’s key players, Kyle Tucker and Alex Bregman, before Opening Day. The prospect of losing Framber Valdez after the season makes the early elimination feel even worse.

One of the main reasons Houston missed the playoffs is simply that it’s really hard to make up for shedding Tucker and Bregman in a single winter. Add in Yordan Alvarez’s season being ruined due to hand problems, and you’re talking quite a few wins that suddenly went poof! into the aether. As a result, the Astros fell to 12th in position player WAR, the first time they’ve been that low over a full season since 2014. Read the rest of this entry »
