Every story written about the Mets this offseason starts with Juan Soto, but pretty much all of them immediately introduce a caveat: “They’ll also need to sign more pitching.” And it’s true! The Mets, as constituted after signing Soto, had a fearsome top of the lineup and a mystery box of a pitching staff. But they also had money, which can be exchanged for goods and services, and now they’ve given that money to Sean Manaea, who signed a three-year, $75 million deal to return to Queens last week.

Manaea was comfortably the team’s best starter in 2024. He signed a one-year prove-it deal that valued him somewhere between a swingman and a fourth starter, and he delivered the goods, to the tune of a 3.47 ERA over 181 innings of work. He got even better in the second half, adopting a new cross-fire delivery and changing the shape of his fastball for the better. A down postseason hardly put a damper on his year; the 2024 version of Manaea fulfilled the promise he’d shown since breaking into the majors in 2016.

The question, then, is whether he can do it again. There’s plenty of reason to believe he can. Manaea’s fastball plays much better from a low slot, and he misses enough bats to run an above-average strikeout rate even without a true wipeout pitch. He also got his walk rate under control in the second half of the year, which has long been a sticking point in his game. It’s not so much that Manaea’s wild, but at his best, he was running walk rates around 5%, and that number had ballooned into the 8-9% region in recent years. After changing his delivery in late July, he walked only 6.2% of opposing batters. He’s never going to strike out a gaudy number of guys, but if he isn’t issuing free passes, his stuff keeps hitters off balance and results in a lot of easy innings even without strikeouts.

Last offseason, the Diamondbacks were in search of a marquee starter to pair with Zac Gallen atop their rotation. The market was thin at the top – Yoshinobu Yamamoto and Shohei Ohtani were probably never available to them, so their best options were Sonny Gray, Blake Snell, Eduardo Rodriguez, Shota Imanaga, and Jordan Montgomery. They signed two of those guys, and neither delivered the rotation-stabilizing performance they had expected. But instead of waving their hands in the air and raving at the injustice of variance, the Diamondbacks got right back on the horse:

BREAKING: Corbin Burnes to Diamondbacks, $210M, 6 years. opt out after 2 years

— Jon Heyman (@jonheyman.bsky.social) 2024-12-28T06:32:12.313Z

Corbin Burnes was the best free agent pitcher available. In each of the last five seasons, he’s been one of the top pitchers in the game, racking up a 2.88 ERA, 3.01 FIP, and 816 innings pitched. He’s second in WAR (21.7) over that time frame, second in RA9-WAR (23.2), second in strikeouts (946), and third in innings pitched. In other words, he’s been a capital-A Ace, a set-it-and-forget-it choice at the top of the starting rotation. He’ll receive $35 million a year for six seasons, with an opt-out after the second year of the deal, which also includes a $10 million signing bonus.

With Gallen also on their dance card, the Diamondbacks have one of the best one-two combinations in the majors. That doesn’t even include Merrill Kelly, a borderline All-Star when healthy, or Brandon Pfaadt, who looked like he was finally breaking out before a rough final two months of the season. Add in Montgomery and Rodriguez, and Arizona goes six deep with plausible playoff starters. That’s how you injury-proof a rotation – sheer depth.

Hi, I’m Ben Clemens. You might know me from such articles as “C’mon, Orioles, Do Something”, “Why Are the Orioles’ Playoff Odds So Low?”, and “Wait, FanGraphs Is Too Low on the Orioles Again?!”. In my spare time, I also write about the rest of the league, but today I’m focusing on Baltimore yet again given their latest signing: The O’s and right-hander Tomoyuki Sugano have agreed to a one-year, $13 million contract.

Sugano has been one of the best pitchers in NPB for more than a decade. The 35-year-old won the Central League MVP in 2014, and he’s added two more MVP awards since then. He also won two Sawamura Awards – think the Cy Young, only for the entire league and with minimum criteria – neither in any of his three MVP seasons. In other words, he’s been racking up hardware like no one else for his entire career.

Reading a scouting report on Sugano is like chicken soup for my command-obsessed soul. If pitching was entirely about hitting a tiny target, Sugano might be the best pitcher in the world. Saying that he has the ball on a string would be offensive to Sugano; I can’t control a yo-yo as well as he can spot his five-pitch arsenal. He walked 16 of the 608 batters he faced last year, a 2.6% rate that would make George Kirby jealous.

It’s not just walk avoidance that sets Sugano apart from the crowd, though. He works the corners and tunnels his pitches off of each other to great effect. He can add or subtract from everything he throws, so his five-pitch mix can feel even deeper when a hitter is trying to figure out what’s coming next. He might not inspire the physical discomfort batters experience when facing triple-digit heat that could come right at their ribcage if the pitcher misses his location, but facing Sugano is like solving a Saturday crossword puzzle, if crossword puzzles threw splitters.

The Winter Meetings always feature trades, but two stood above the fray last week. First, the Guardians traded Andrés Giménez to the Blue Jays in a two-part transaction that briefly left Cleveland with three lefty-hitting first basemen. Then the White Sox traded Garrett Crochet to the Red Sox for four prospects. The best of that group, Kyle Teel, happens to play catcher, the same position as Chicago’s top prospect Edgar Quero. They even have the same future value grade of 50, which is the cutoff for top 100 prospects.

The Guardians made an extra trade to avoid doubling up on similar archetypes, sending Spencer Horwitz to the Pirates for three young pitchers, but the White Sox just kept both catchers. I heard a lot of murmured questioning of that decision as I walked around the Dallas hotel that briefly hosted the center of the baseball universe. But I think both teams were acting rationally, and that worrying about Teel and Quero overlapping is silly. I can’t prove it for you – but I did come up with some data that will hopefully sway your opinion.

Cleveland’s case was straightforward. Steamer projects Horwitz as a 2.5 WAR/600 PA player. It projects Kyle Manzardo as a 1.8 WAR/600 PA player. Josh Naylor? Steamer has him down for 2.4 WAR/600 PA. Three players for two positions — first and DH. (Yes, Horwitz has played second base, too, but he really shouldn’t be a second baseman, and I don’t think the Guardians would’ve used him there.) One of them would ride the bench despite being an above-average contributor, a poor decision for a team that’s trying to maximize its resources. Something had to give.

On the other hand, there are the White Sox. They, too, traded a young star, and the best player they got back plays a position where they already had a similar option. Teel was our 42th-ranked prospect on our updated Top 100 list in 2024, a polished all-around catcher who we expect to reach the majors at some point in the next two years. Quero was our 40th-ranked prospect, and you’re never going to believe this, but he’s a polished all-around catcher who we expect to reach the majors at some point in the next two years.

It’s a ritual as old as time. The Brewers develop an intriguing young player into an All-Star, and a fun one at that. Next, that player approaches free agency – that’s how time works. The Brewers then trade that player to a contending team, getting back a few players with multiple years of team control. Finally, the Brewers develop those players into stars, spin the wheel again, and the band plays on. Today’s edition: Milwaukee traded Devin Williams to the Yankees in exchange for Nestor Cortes and infield prospect Caleb Durbin, as Jeff Passan first reported.

Williams is the rare pitcher who isn’t even as famous as his best pitch. His screwball/changeup hybrid is nicknamed The Airbender, and it’s been making major leaguers look like overmatched kids for years. On the back of that pitch and a plus fastball, he’s compiled a career ERA of 1.83 over five-plus seasons of dominance. His 39.4% career strikeout rate reads like a typo. He rose to prominence during the 2020 season, and he’s been the second-best reliever in baseball since then, trailing only Emmanuel Clase.

It doesn’t matter what you call the pitch; Williams’ results speak for themselves. “Changeup-first dominant closer” only sounds fluky until you look at the raw data. He misses more bats than Josh Hader. He might even be better than his run-prevention numbers would suggest, because the runs he gives up come in bunches. In 2023, for example, he gave up 10 earned runs all year, and four were in a single game. The upshot: He’s first among relievers in win probability added by a ton, because a truly outrageous number of his games end in scoreless innings. He’s not Mariano Rivera, but he might be the closest thing in today’s game: an automatic ninth inning.

“Hey, they won’t have to say ‘we tried’ this time.” I can’t attribute that quote to anyone in particular, but the Winter Meetings were abuzz with variations on a theme. After missing out on Juan Soto and Max Fried earlier in the week, the Boston Red Sox switched gears from free agency to the trade market and found their star. In a blockbuster deal, they’re acquiring Garrett Crochet from the Chicago White Sox in exchange for Kyle Teel, Braden Montgomery, Chase Meidroth, and Wikelman Gonzalez, as Julian McWilliams of the Boston Globe first reported.

This is the biggest trade of the offseason, and it’ll almost surely still occupy that position when next season rolls around. Pitchers like Crochet don’t hit the market very often. He blew the doors off the league in his first year of starting, pairing premium velocity with two excellent secondaries. He threw 146 innings, struck out more than 200 batters, and barely walked anyone while doing so. His strikeout stuff, exploding fastball, and lanky lefty frame call to mind Chris Sale, another Sox-to-Sox trade piece, and with the White Sox in the middle of a gut-renovation rebuild, he was always likely to get traded. The only questions were who for, and which team was most interested in adding him to their rotation.

We’ll cover the ins and outs of the prospects included in the deal in a separate post. Broadly speaking, though, the White Sox got a little bit of everything in their return. Teel is a Top 100 catching prospect approaching major league readiness with impressive speed. Montgomery is a high-risk, high-reward outfield prospect, the 12th pick of the 2024 draft. Gonzalez has mouth watering stuff that took a step back this year, and a sky-high walk rate to match. Meidroth is an on-base genius with questionable power and an uncertain defensive future. The White Sox have so many needs that they don’t have to be choosy about filling particular holes or looking for particular profiles. They just need talent. This return fits well with that best player available mentality. Read the rest of this entry »

The Blue Jays came into the offseason at a crossroads. With Vladimir Guerrero Jr. and Bo Bichette headed for free agency after the 2025 season, the pressure is on: Make the playoffs or go the entirety of their team control years without a single playoff win. (They’re 0-6 in three Wild Card series.) It’s no surprise they were in on Juan Soto, and after coming up short there, they pivoted to the trade market, acquiring Andrés Giménez (and Nick Sandlin) from the Cleveland Guardians in exchange for Spencer Horwitz and Nick Mitchell. The Guardians then sent Horwitz on to the Pirates in exchange for Luis L. Ortiz, Michael Kennedy, and Josh Hartle, all of whom we’ll break down in a forthcoming post.

This trade improves the Blue Jays’ outlook for 2025, and it does so in a way that fits their recent team-building to a T. Two years ago, they added Daulton Varsho and Kevin Kiermaier, perhaps the two best defensive outfielders in baseball, and frequently played them together. They gave Santiago Espinal regular playing time when his defense graded out well, then phased him out in favor of new defensive wunderkind Ernie Clement when Espinal faltered defensively. They used Isiah Kiner-Falefa to patch defensive holes across the diamond until they traded him this past summer. Now they’re adding Giménez, one of the best infield defenders in all of baseball, to the mix.

Last season marked Giménez’s third straight Gold Glove and second straight Fielding Bible award. The voters (full disclosure: I am one of them) didn’t give it to him on reputation. He’s not just a shortstop playing second base; he’s a very good shortstop playing second base. He has the strongest throwing arm of any second baseman and uses it to his advantage, ranging up the middle to make outrageous plays. He has soft hands and quick reflexes. Statcast credits him with 37 runs above average over the past three years, tops in the majors. DRS thinks Statcast is being too modest – it credits him with 59 runs saved, 22 ahead of second place.

I don’t know the name for this phenomenon, but I’m guessing everyone has experienced it at some point. You hear something enough times, and you start to repeat it without really thinking critically about it. My example: the breakeven stolen base rate. I’ve heard that term so many times over the years, often in connection with whether teams were stealing too much or not enough, that I incorporated it into my thought processes like it was my own.

But then someone asked me why the optimal stolen base success rate was around 70%, and I realized that I’d been wrong. It was a bolt-of-inspiration kind of moment – you only need to hear the counter-argument once to re-assess your old, uncritically assumed thought. Why should teams keep stealing so long as they’re successful more than 70% (ish) of the time? I couldn’t explain it to myself using math.

The other side of the coin, the notion that teams should be successful at far better than the breakeven rate in the aggregate, is incredibly easy to understand. There’s a difference between marginal return and total return. Consider a business where you’re making investments. Your first investment makes $10. Your next one makes $8, and then $6, and so on. You could keep investing until your business breaks even – until you make a negative $10 investment to offset that first one, more or less ($10+$8+$6+$4+$2+$0-$2-$4-$6-$8-$10). But that’s a clearly bad decision. You should stop when your marginal return stops being positive – when an investment returns you $0, you can just stop going and pocket the $30 ($10+$8+$6+$4+$2+$0).

For a month or so every year it seems, Danny Jansen looks like Babe Ruth. The only season out of the past four in which he hasn’t put up a 20-game stretch with a wRC+ over 200 was 2023, and he was pretty awesome in 2023 anyway; he posted a 115 wRC+ overall that year, while playing the most offensively-challenged position in the sport, no less. So in some ways, the Rays might have just signed the best offensive catcher in baseball:

@JeffPassan tweetedCatcher Danny Jansen and the Tampa Bay Rays are in agreement on a one-year, $8.5 million contract that includes a mutual option for a second season, sources tell ESPN. Jansen, who has played in Toronto and Boston, remains in the AL East. On it: @ByRobertMurray and @TBTimes_Rays.

— Passanthallich (@passanthalbot.bsky.social) 2024-12-06T18:18:18.487825+00:00

Of course, when it comes to overall production, they absolutely didn’t. Jansen was white hot to start the year in 2024 – and then ended the season with an 89 wRC+, going from target deadline acquisition to backup in the process. And while he has indeed hit well when healthy, he gets hurt a lot. Across those aforementioned four seasons, he’s accumulated only 1,078 plate appearances. He hit the IL twice in 2021, twice again in ’22, twice yet again in ’23, and then missed the start of the ’24 season rehabbing from the last ’23 injury.

So maybe Jansen is secretly an amazing hitter – or maybe it’s a miracle that he can even still play baseball. Either of those could be true, and of course the truth is likely somewhere in between. The Rays are famously good at discerning where in the “somewhere in the middle” players lie, and as such, they feel like a natural home for Jansen.

Finding catchers who can both hit and field is nearly impossible. The Rays haven’t particularly prioritized them in the draft, and they certainly haven’t gone out of their way to trade for or sign marquee catchers. That’s how they ended up with Ben Rortvedt (career wRC+: 70) as their primary catcher in 2024. In 2023, that role went to Christian Bethancourt (career wRC+: 71). In 2022, Bethancourt backed up Francisco Mejía (career wRC+: a scintillating 86, though with poor defense).
