Andy Pages Is a Perfect Fit

Jason Parkhurst-Imagn Images

You know Shohei and Clayton and Freddie and Mookie. Teo and Will Smith and Blake Snell and Roki. But do you recall the least heralded Dodger of all? Well, that’s not exactly fair, and I didn’t even name all the famous Dodgers, but here’s the point: I’m writing about a Dodger who isn’t one of the guys who seem to steal every headline.

Meet Andy Pages, the Dodgers’ everyday center fielder. A year ago, Pages was just another hopeful, the latest in a line of plus-bat, where-can-he-play-defense-though options cycling through the corners in Chavez Ravine. Pages’ prospect reports paint a clear picture: a swing built for lift, plenty of swing-and-miss, and sneaky athleticism that exploded after Pages returned from shoulder surgery. In 116 games of big league play, he took over center field (mostly out of necessity — he looked stretched there at times) and posted a league average batting line, though without the home run power that evaluators expected from him.

If you could freeze time there and give the Dodgers the option of having exactly that Pages for the next five years, I think they would have begrudgingly accepted it. Teams as full of stars as Los Angeles’ current squad need role players to fill the cracks in the roster, and outfielders who can handle center and hit at least okay are always in high demand. That isn’t to say that there weren’t encouraging signs – Pages’ athleticism was better than advertised and he showed plus bat speed – but a bird in the hand is worth two in the bush, and he was already an excellent cog in the machine even without fully unlocking his power.

Flash-forward to this season. Pages started the year playing center and batting ninth. That’s the lineup spot for a complementary piece, a defensive specialist or fourth outfielder. He started slow, with a 70 wRC+ over his first month of play. The Dodgers didn’t have better options defensively, and in fact, Pages looked downright smooth out there, both to my eyes and to defensive model grades. When your team posts a collective 126 wRC+ for the months of March and April (for the months of May and June so far, too — this team is pretty good!), you can live with a below-average hitter playing a tough defensive position, so the Dodgers kept running Pages out there, slow start and all. And that brings us to April 22, when Pages got hot and didn’t stop. Read the rest of this entry »

Carlos Santana’s Encore Features New Material

Brad Penner-Imagn Images

Author’s note: Five Things will return next week. In the meantime, enjoy an article about one of my favorite players.

Do you want to know how much Carlos Santana loves playing baseball? From 2020 through 2023, he played for five teams, got traded midseason twice, and compiled a 94 wRC+. He was 37, had earned more than $100 million in his career, and didn’t have an obvious everyday starting job lined up. He could have hung up his spikes right then – but he took a one-year, $5.5 million deal with the Twins and turned back the clock with a 114 wRC+. Then he signed another one-year deal, this one for $12 million with the Guardians, and kept the train rolling. Through the first third of the season, he’s on pace for his best year in more than half a decade.

What’s his secret? As a fellow 39-year-old, I wanted to find out – for, you know, mostly professional reasons, but also because sometimes my knees hurt after going on a particularly brisk walk. Bad news for me, though. I’ve found out one thing that Santana has done in 2025 to rejuvenate himself, and I’m not sure that I can replicate it in my personal life.

Let me explain. If you look at Santana’s Baseball Savant percentile rankings, you won’t come away impressed:

Yes, we get it, the man has an elite sense of the strike zone, and he’s still great at defense — no big surprise — but it’s a bit of a bummer if we look only at the bar graphs above Chase%; there’s not a ton of loud contact, not a ton of squared-up contact, and he’s rarely hitting the ball on the sweet spot. That’s a lot of blue for a guy running a 123 wRC+ and getting an article written about his late-career resurgence. Read the rest of this entry »


The Ongoing Battle for the Top of the Strike Zone

There’s a war going on across major league baseball. It’s been waged over decades, in fact, between two opposing factions of the game. Pitchers, at times aided by their catchers, want to own the top of the strike zone, the place where their fastballs have the easiest time missing bats. Hitters want to hit home runs, and the top of the zone is an ideal launching pad. But while both sides would dearly love to own the territory, they can’t both win at once. What follows are some dispatches from the front, the latest moves and counter-moves by some of the game’s best in this contested space.

Chad Patrick lives at the top of the zone. No pitcher in baseball throws upstairs fastballs more frequently. He might not seem like the type. He’s a soft tosser in the context of the modern major leagues, sitting in the low 90s with his four-seamer and sinker, and the high 80s with his cutter. But for Patrick, shape is more important than velocity.

As Alex Chamberlain has extensively explained, the plane of a pitch when it reaches home plate is a key determinant of its success. That’s most true at the top of the zone for four-seamers. Pitches that come in high and flat act like optical illusions – the average fastball thrown to that area falls more, because it’s falling at a steeper angle. Read the rest of this entry »


Luis Torrens Has Arrived, Just a Few Years Late

Brad Mills-Imagn Images

If, like me, you’re a weird baseball transactions sicko, you probably first heard of Luis Torrens at the tail end of 2016. That’s when the Padres, in the midst of an A.J. Preller-led teardown, shocked baseball by taking three low-minors players in the Rule 5 Draft and putting them all on the major league roster for 2017. It was a bold, unheard of tactic. The three players – Allen Córdoba, Miguel Díaz, and Torrens – were clearly not ready for the majors. Torrens, the most advanced of the trio, was 21 and had around 200 plate appearances of full-season minor league ball under his belt, and he was still learning his new position of catcher.

That trio was famously overmatched in 2017. Torrens racked up -1.3 WAR in 139 plate appearances, Córdoba -1.0 WAR in 227 of his own, and Diaz -0.7 WAR in 41 2/3 innings pitched. The whole experiment was an embarrassment for the league, and no one has since tried similar chicanery. The Padres sent them down after the season, as soon as they were eligible to do so without having to return them to their previous organizations; Torrens and Córdoba spent all of 2018 in the minors, and both struggled in A Ball. Torrens did finally return to the majors as a backup in 2019, but Preller flipped him to Seattle a year later and he slid into journeyman status. From 2019 through 2023, he bounced around, rarely getting consistent playing time, ending up with 668 plate appearances, a 92 wRC+, and -0.4 WAR thanks to iffy defense.

I’ve used what San Diego did in this particular Rule 5 Draft as a cautionary tale when people ask me about the risks of rushing low-level minor leaguers to The Show. I firmly believe that this Rule 5 manipulation interrupted each of their career arcs – they just weren’t ready for the challenge, which is hardly unexpected given where they’d been playing. Each was a promising prospect, but in the six years after the Padres selected them, the amount of time you’d expect them to be under team control, they combined for -3.2 WAR.

Can the Diamondbacks Survive Their Rotation Troubles?

Mark J. Rebilas-Imagn Images

The Diamondbacks did things the “right way,” to the extent that the right way means anything. After making the World Series unexpectedly in 2023, they went into the offseason with an exciting group of hitters and an unsettled rotation, so they opened the vault and signed two of the top-10 free agents that year — Eduardo Rodriguez and Jordan Montgomery — both starting pitchers. When those two flamed out in 2024 but the hitters kept producing, they went back to the well and signed Corbin Burnes, another marquee option. They refused to include top starting prospects in trades. They already had Zac Gallen and Merrill Kelly in the fold. This is how you build a top rotation.

Er, well, this is a way that you can build a top rotation, but this particular iteration hasn’t panned out. In Phoenix, things are falling apart on the mound. Let’s look through Arizona’s problem rotation spots (read: everyone other than Kelly) and see if we can find a solution for each before it’s too late for the team’s 2025 season.

Corbin Burnes

The Problem: Injury
Burnes got off to a slow start in the desert, but like the weather in his new place of work, he was heating up as the year wore on. His cutter isn’t quite the devastating weapon it was during his 2021 Cy Young season, but it’s still a menace. He’s still one of the best in the business when it comes to spinning breaking balls. A well-located Burnes curveball is an absolute masterpiece, a pitch that will make you question the very basics of physics and reality.

In Burnes’ most recent four starts, he’s gone nuclear: 31% strikeout rate, 2.19 ERA, 2.67 FIP. He’d also been stacking up volume: Three of his past five starts lasted seven innings. But the most recent start ended prematurely in the fifth inning, when Burnes felt sharp tightness in his elbow, saw his velocity drop, and left the game. Burnes said after the game that he didn’t know the severity of the injury, telling reporters, “I’ve never had anything like it before, so I really have nothing to compare it to.”

Five Things I Liked (Or Didn’t Like) This Week, May 30

Tim Heitman-Imagn Images

Hello, and welcome to another edition of Five Things I Liked (Or Didn’t Like) This Week. Memorial Day marks the point at which we’re a third of the way through the season, a great time to take stock of how preseason story lines have fared in the light of the regular season day. The Orioles might be bad. The Phillies and Tigers might be great. The Rockies might be the worst team of all time. Aaron Judge might be an alien. We’ve learned a lot so far – but none of those things affect the day-to-day experience of watching baseball. That’s what I like about it so much – you can turn on a random game, completely ignore any of those overarching narratives, and still see something delightful. So this week, let’s celebrate the little things that don’t necessarily win games but do consistently bring a smile to my face. With my customary nod to Zach Lowe of The Ringer for his basketball column that inspired this one, let’s dive in.

1. Determination
I’ve always been fascinated by Nick Allen, who blends elite shortstop defense with a completely powerless approach to offense. That combination got him traded to the Braves this winter to play a utility infielder role, but he outplayed Orlando Arcia in spring training to claim the starting job, and he’s been running with it. Not on offense – his 68 wRC+ is both mortifying and a career high – but on defense, he’s never been better.

Allen’s defense is many things, but most importantly to me, it’s kinetic. He doesn’t give up on plays. He’s always moving. He’ll throw from any platform, any arm angle, jump or twist or slide to get more force behind it. He’s graceful around second base, but it’s a nervous kind of grace, a ballet dancer after four shots of espresso. And if something gets in his way, he’ll just run through it:

The Run Expectancy Matrix, Reloaded for the 2020s

Gary A. Vasquez-Imagn Images

This is a public service post of sorts. If you’re like me, when you type “Run Ex” into Google, it will auto-complete to “Run Expectancy Matrix.” It knows what I want – a mathematical description of how likely teams are to score in a given situation, in aggregate. I use this extensively in analysis, and I also use it in my head when I’m watching a game. First and third, down a run? That’s pretty good with no outs, but isn’t amazing with two.

There’s just one problem with that Google search: It’s all old data. Oh, you can find tables from The Book. You can find charts that are current through 2019. There’s a Pitcher List article that I use a lot — shout out to Dylan Drummey, great work — but that’s only current through 2022. And baseball is changing so dang much. Rather than keep using old information, I thought I’d update it for 2025 and give you some charts from past years while I’m at it, so that you can understand the changing run environment and use them for your own purposes if you so desire.

First things first: Let’s talk methodology. I downloaded play-by-play logs for all regular season games played between 2021 and 2025. For each play, I noted the runners on base, the number of outs, and then how many runs scored between that moment and the end of the inning. I did this for the first eight innings of each game, excluding the ninth and extras, because those innings don’t offer unbiased estimates of how many runs might score. Teams sometimes play to the score, and the home team stops scoring after the winning run. If you have the bases loaded and no one out in the bottom of the ninth, one run will usually end it, and that provides an inaccurate picture of run scoring. That’s also why I skipped 2020; the seven-inning doubleheaders and new extra innings rules produced a pile of crazy results, and the season was quite short anyway. No point in trying to wade through that maze. Read the rest of this entry »


The Math Behind the Extra Innings Home Field Disadvantage

Joe Nicholson-USA TODAY Sports

Home teams don’t win enough in extra innings. It’s one of the most persistent mysteries of the last five years of baseball. Before the 2020 season, MLB changed the extra innings rules to start each half of each extra frame with a runner on second base. (This only occurs during the regular season, which means the 18-inning ALDS tilt between the Mariners and the Astros in the picture above didn’t actually feature zombie runners, but the shot was too good to pass up.) They did so to lessen the wear and tear on pitchers, and keep games to a manageable length. Almost certainly, though, they weren’t planning on diminishing home field advantage while they were at it.

In recent years, Rob Mains of Baseball Prospectus has extensively documented the plight of the home team. Connelly Doan measured the incidence of bunts in extra innings and compared the observed rate to a theoretical optimum. Earlier this month, Jay Jaffe dove into the details and noted that strikeouts and walks are a key point of difference between regulation frames and bonus baseball. These all explain the differing dynamics present in extras. But there’s one question I haven’t seen answered: How exactly does this work in practice? Are home teams scoring too little? Are away teams scoring too much? Do home teams play the situations improperly? I set out to answer these questions empirically, using all the data we have on extra innings, to get a sense of where theory and practice diverge.

The theory of extra inning scoring is relatively simple. I laid it out in 2020, and the math still works. You can take a run expectancy chart, start with a runner on second and no one out, and figure out how many runs teams score in that situation in general. If you want to get fancy, you can even find a distribution: how often they score one run, two runs, no runs, and so on. For example, I can tell you that from 2020 to 2025, excluding the ninth inning and extra innings, teams that put a runner on second base with no one out went on to score 0.99 runs per inning.
