“Could be, like, where I’m at on the ball too, but…”

With that fragment, Nolan McLean kicked off the baseball season. Ask a dozen baseball fans when they think the season starts, and you’re likely to get five or six different answers. Maybe you think the season starts on Opening Day, or with the first showcase series before Opening Day, or when spring training games start, or when your local broadcast starts actually airing spring training games, or on the first day of spring training, or when pitchers and catchers report, or on truck day. Or maybe you just think that all of these milestones deserve to be celebrated in their own right as we creep out of the cold toward actual, meaningful baseball. Nobody’s wrong, but some of us believe that baseball begins when grainy cellphone footage of players performing baseball-related activities on the backfields in Florida and Arizona starts trickling into our social media feeds. If you count yourself among that cohort, then congratulations. Baseball season has started.

McLean was on the mound at Clover Park, the Mets’ spring training facility in Port St. Lucie, Florida to throw some sort of bullpen session alongside fellow prospect Jonah Tong. Someone on staff captured footage of the two young players pitching, and both videos went up on social media in the early afternoon on Monday. The videos were taken vertically, then cropped down to an awkward 672×768 pixel ratio, but they featured the loud pop of ball meeting glove, and that’s enough. By virtue of being posted first, McLean’s kicked off the season. Read the rest of this entry »

Jay Jaffe: Good afternoon, folks! Greetings from Brooklyn, where it’s almost freezing — which seems genuinely balmy after temperatures in the teens all last week. We’re apparently in the midst of the longest stretch of sub-freezing days in NYC in the past 65 years. Hoping my new space heater arrives today, but wish it had been around last week (I have a lower-powered but less energy-efficient one).

Jay Jaffe: After taking a few days off last week to recuperate from te Hall of Fame election cycle crunch, yesterday I wrote about the Giants signing Luis Arraez to a one-year deal https://blogs.fangraphs.com/on-second-thought-giants-sign-free-agent-l…

Jay Jaffe: Today I have the first of a two-piece series covering the still-available free agents. This one rounds up the position players and will probably go up while I’m mid-chat; apologies if I have to duck out here and there to answer an editorial query.

Jay Jaffe: Two things to note before we get started, both of which went by on Bluesky. First, today is the day that the BBWAA has published the ballots of all Hall of Fame voters who granted permission; apparently it includes about 100 which aren’t in Ryan Thibodaux’s Tracker. He and his team will be adding those. https://bbwaa.com/26-hof-ballots/

One of my favorite sports movie tropes is the Scrappy Underdogs Who Discover the Power of Friendship. While there are myriad variations on the theme, the basic template involves a group of lovable losers facing off against some big baddie and initially being humiliated. As the movie goes on, the various underdogs unite against their common foe, and through determination, grit, moxie, and typically some shenanigans, they meet their antagonists again, only on more even footing. Ideally, our ragtag band emerges victorious, but even if they don’t, they’ve at least learned something about themselves and friendship, often earning the grudging respect of their rivals along the way.

The Yankees were once baseball’s Evil Empire, but these days, the Dodgers reign supreme. They’re rich, they’re smart, they play in a ritzy city, and they would definitely look down on the kids at the ramshackle summer camp across the lake. As it has in most recent seasons, ZiPS projects the Dodgers to be the best team in baseball, and the newly-released FanGraphs Playoff Odds agree. But baseball needn’t accept its projected fate. It’s time to fight back! It’s time to unite some scrappy underdogs — at least on a spreadsheet. And so, with a tip of the hat to Tom Tango, whose theoretical inspired me to put together this piece, to the computer!

To construct our ragtag squad, we’ll start with the worst projected team in baseball, the Rockies, and ask ZiPS to build the best 26-man roster it can to square off against the Dodgers in a fictional seven-game World Series. I’m looking for two probability thresholds here: A Fighting Chance (a one-in-three shot of winning the series) and the Hunter Becomes the Hunted (the underdogs pass the 50% mark). If a roster made entirely of Rockies fails to meet these thresholds, then the players from the next-worst projected team will join the pool. We’ll keep repeating the process until our heroes emerge victorious. Read the rest of this entry »

I’m not going to pretend that you should care about, or even have heard of, Carmen Mlodzinski before now. He’s a spot starter and medium-leverage reliever on a bad team that gets 90% of its national attention when a specific other pitcher is on the mound. And if you’re not watching the Pirates for Paul Skenes, you’re probably watching them for Bubba Chandler or Mitch Keller or (before he got hurt) Jared Jones, and changing the channel when the bullpen comes in.

It’s fine. Life, unlike Skenes, is short. There are many more important players out there than Mlodzinski.

Nevertheless, he’s doing some fun stuff and I’d like to tell you about it. Read the rest of this entry »

The first thing Chaim Bloom did after taking over baseball operations in St. Louis was trade away everything that wasn’t nailed down. Sonny Gray? Thanks for your contributions, now go try to win a ring in Boston. Willson Contreras? Gone, and to the same team. Nolan Arenado? Thanks for the memories, enjoy the desert. With those trades sorted, he’s moved on to step two: prying up some of those aforementioned nails to make more deals. The most recent shoe to drop in the Cardinals retooling might be the biggest one, though. Brendan Donovan is now a Seattle Mariner, the key piece in a three-team trade that sends Ben Williamson to Tampa Bay and a heaping helping of prospects and draft picks to the Cardinals.

Donovan isn’t a household name like many of the best Cardinals of recent years, but that has far more to do with the team’s middling success of late than any lack of talent. His combination of versatility and offensive firepower calls to mind Ben Zobrist, and unlike almost every other flexible defender who gets compared to Zobrist, this one actually makes sense. Zobrist ran a 121 wRC+ during his seven-year peak. Donovan’s career mark is 119, the same as his 2025 total. He’s under team control for two more years at a reasonable rate, too: $5.8 million this year, with his last trip through arbitration set for 2027.

“A plus bat who can play defense everywhere” generally isn’t a good title to have applied to you. That’s because most of the hitters who receive that label either aren’t plus bats, don’t play good defense, or both. But as I mentioned, that’s not Donovan, and we might as well examine each of those two skills, as he’s the entire reason this trade happened, the best player going to any of the three clubs by a mile.

It took all the way until February, but the last few free agency dominos are starting to fall. The Reds were one of the first teams to dip their toes into the market this winter, signing Emilio Pagán to a two-year deal at the start of December. Now they’ve made it a bookend set – over the weekend, they signed Eugenio Suárez to a one-year, $15 million deal, as first reported by Jeff Passan.

I missed high on my contract estimate for Suárez. I had him down for two years at $25 million a year, while our crowdsourced projections thought he’d get three years at $20 million each. The lowest public-facing projection I found for him was two years at $22.5 million per. In other words, Suárez settled for less than predicted, and he signed late as a result. It’s a classic example of the fact that free agents who sign later sign for less.

At a top-line level, seeing Suárez sign for this little is surprising. He isn’t some flash in the pan seeking a 10-year deal. He’s been one of the best power hitters in baseball for quite a while now. The 2025 season was the fourth out of the last five where he’s topped 30 homers. He socked 49 while spending half the year in a home run graveyard in Seattle, though he did most of his damage before the trade; he posted a 91 wRC+ as a Mariner. Teams pay for projection, not performance, but Suárez’s wRC+ over the last three years is better than his career mark. But that power didn’t overwhelm a host of other question marks.

After getting what amounted to replacement level production at second base last season, the Giants have a new man for the keystone. The good news is that he’s a three-time batting champion, and he’s not outrageously expensive. The bad news is that lately he hasn’t been an incredibly productive hitter despite his high batting averages, and what’s more, second base could be a stretch. However it shakes out, on Saturday the Giants agreed to terms with free agent Luis Arraez on a one-year, $12 million deal.

Arraez, who will turn 29 on April 9, spent last season and most of the previous one with the Padres after being acquired from the Marlins in a May 4, 2024 trade. While he won his third straight batting title in 2024 and made his third consecutive All-Star team, his time with San Diego was one of diminishing returns on both sides of the ball. Last year again he led the NL with 181 hits, but his .292/.327/.392 slash line only amounted to a 104 wRC+, the lowest mark of his career and down from a 109 wRC+ (on .314/.346/.392 hitting) in 2024. By comparison, he hit for a 130 wRC+ (.316/.375/.420) when he won the AL batting title with the Twins in 2022 and a 131 wRC+ (.354/.393/.469) when he won the NL batting title in ’23. He slipped from being more or less a three-win player (6.1 WAR in 2022–23) to a one-win player (2.0 WAR in 2024–25).

Arraez is an odd duck, an anachronism in that the things he’s best at don’t fit this historical moment particularly well. At a time when home run and strikeout rates are near their all-time highs and batting averages closer to an all-time low, he’s the game’s most contact-oriented hitter, as well as the active leader in batting average (.317). That makes him a fun player to theorize about, as colleague Davy Andrews did when he recently pondered the possibility of Arraez signing with the Rockies, whose spacious ballpark would’ve provided him with the most room to run up his batting average on balls in play by dumping single after single in front of outfielders playing deep.

Life is moving fast for Jacob Wilson. The 23-year-old shortstop got married in December, and on Friday, he agreed to a seven-year, $70 million contract extension to stay in West Sacramento. (Well, he’ll be in West Sacramento for two seasons, anyway, and then after that it’s a bit unclear where he’ll be staying, but wherever it is, it’ll be with the Athletics.) Wilson was under team control for five more seasons, but the deal, first reported by ESPN’s Jeff Passan, adds two more years to that total, with a team option for an eighth. If the A’s exercise that option, Wilson will reach free agency for the first time after the 2033 season, when he’ll be 31.

Wilson is coming off an eye-opening rookie campaign. Despite missing a month during the summer after a pitch fractured his forearm, he put up 3.5 WAR, a 121 wRC+ and a .311 batting average. He earned an All-Star nod and picked up an MVP vote, and had he given in to what must have eventually been very strong temptation to poison teammate Nick Kurtz, he could have even taken first place in the Rookie of the Year voting. However, that doesn’t mean he’s a four-win player going forward.

It’s not impossible that Wilson could keep running a batting line that’s 20% better than the league average, but it would be foolish to go into the 2026 season with that expectation. He’s cut from the same cloth as Luis Arraez and Steven Kwan, a pure contact hitter who swings slow and squares the ball up, eschewing both power and patience. Like many hitters who can hit anything, he tends to swing at everything. As a result, he never walks or strikes out, which means he really needs the ball to find grass. In 2025, it did just that. Wilson’s .311 batting average was 34 points above his expected mark, which tied him for the biggest gap among all qualified players. Read the rest of this entry »

Not every team shows up for spring training with a reasonable hope of winning the World Series, but there is a grand, overarching narrative to follow in every camp. For the Chicago White Sox, it’s whether they can achieve an all-Sean-and-Shane starting rotation — they’re currently 60% of the way there.

That might sound like a modest goal, but it’s a lot more ambitious than what they set out to achieve just last year: Avoid losing 120 games. Again. The White Sox will sink or swim (or at least sink more slowly) based on how their young homegrown players perform, but Chicago’s supporting cast is looking relatively OK.

All the more so after this weekend, when the White Sox made two moves: signing free agent outfielder Austin Hays to a one-year contract, and trading for Red Sox pitchers Jordan Hicks and David Sandlin. Read the rest of this entry »
