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!

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.

Last week, I did a radio hit in Baltimore to talk about the Orioles’ five-year extension for right-handed starter Shane Baz. As you might expect, I got asked for my general impressions of the Orioles’ rotation, and I gave an answer I did not expect to be controversial: I like Baltimore’s rotation, and I’m quite fond of Trevor Rogers and Kyle Bradish, the top two starting pitchers. That said, the Orioles don’t have a clear no. 1-quality starter, which could end up as a weakness in a playoff series.

“Ace” and its synonyms are fuzzy in meaning, so I’ll define my terms as clearly as I can: I meant that the Orioles don’t have a starting pitcher who can be expected to go up against one of the top pitchers in the league and fight him to a draw for six innings. I’ll give an example from last year’s World Series: I think Yoshinobu Yamamoto is a better pitcher than Kevin Gausman — and sure enough, Yamamoto beat Gausman twice in as many attempts — but the difference isn’t so great that you’d be able to tell over one start.

I got some pushback on social media — some of it quite intense — from Orioles fans who like their chances with Rogers against Tarik Skubal. Every sports fan thinks they’re the center of the universe these days, and accordingly that everything about their team is better than the biased national media will give them credit for. (Except White Sox and Twins fans, who think everything about their team is even worse than the biased national media realizes.) Even if that weren’t true, I would ordinarily never admit to treating randos on X, the Everything App, like an assignment editor. That way lies madness. Read the rest of this entry »

We’ve released a new tool in the FanGraphs Lab. The Paired Pitches tool is a visualizer that shows how the different pitches that a pitcher throws interact with each other. It measures how much gravity, speed, and movement make each pitch diverge from a common center point. It’s probably easiest to start with a picture. This is Yoshinobu Yamamoto’s pitch mix as shown in the Paired Pitches tool:

To use the tool, you pick a pitcher, pick a pitch, and then click anywhere on or around the strike zone to locate that pitch. The tool then locates every other pitch the pitcher throws in relation to that pitch. You can drag any pitch in the resulting graphic to move the locations around, and they’ll remain paired with each other, with the same relative movement distribution:

If you’re wondering why a hitter might swing over a Yamamoto slider in the dirt, it’s because its initial trajectory looks a lot like a middle-middle fastball. If you’re wondering why they might take a cutter on the corner, well, it’s because it looks a lot like a slider in the dirt.

Now for a quick math interlude: The way this tool works is by assuming that each pitch is released from a distinct release point, but aimed so that they would intersect at the same point on the two-dimensional plane of the strike zone if they continued traveling from their release point to home plate with no effects from spin or gravity. Think of it as where a pitch would “go” if you just drew a straight line in the direction the ball is moving immediately upon leaving the pitcher’s hand.

Conveniently enough, that idea of measuring movement in comparison to an imaginary, no-acceleration world and plotting intersect points at home plate is exactly how the math of pitch movement already works. The Paired Pitches tool just does the math for every pitch as though they were “aimed” at a point that puts the anchor pitch wherever you want it.

In practice, that’s sometimes but not always how pitchers use their pitches. Pitchers pair some of their pitches, some of the time, and in different combinations. Take Garrett Crochet. He can pair an in-zone fastball with a diving changeup against righties:

Against lefties, he works off of his sinker, turning the zone into a horizontal nightmare for batters. His sinker lives inside, his sweeper dives away, and he can even use the cutter/sinker pairing to get called strikes on the inner half. The same pitches, paired in different locations, have different effects, which is why you can drag them around in the tool and change anchors:

Now that I’ve shown you how much fun it is to pair pitches and think along with pitchers and catchers, it’s time for a few caveats. This shorthand way of explaining how pitches diverge on their path home isn’t going to explain everything about pitching overnight. Curveballs, in particular, don’t fit into this paradigm well. Pitchers don’t “aim” them, in terms of initial trajectory, at the same spot as their fastballs. Curveballs are so slow that they’d just fall too far on the way home. Instead, pitchers aim at a higher point, which helps explain the distinctive “hump” out of the hand that sometimes helps batters pick them up.

We don’t claim that this tool captures everything about pitch interaction. Pitchers can and do select pitches for how they look compared to one another, but they also employ plenty of other tactics. They might want to throw a pitch on a completely different trajectory than the previous one to change the batter’s eye level. They might want to throw a slider that doesn’t tunnel with anything to take advantage of a batter who doesn’t swing at spin early. But frequently, they want to pair a fastball in with a sweeper away and get batters to swing at both of them:

Below, I’ve compiled a list of tips, tricks, and frequently asked questions from some early testing of this tool:

• Bubble sizes are proportional to the movement variation of each pitch. Pitches with variable movement profiles like splitters and changeups have larger bubbles because their movement is less certain from one pitch to the next. Fastballs tend to have smaller variations in their movement. You can change the bubbles to be baseball-sized in the settings.
• If a pitch isn’t showing up, it’s probably because that pitcher hasn’t thrown enough of them in the filter/time frame you’re looking at. You can lower the minimums in the dropdown.
• This tool, and all Lab tools, now have copy and download options. If you want to share a picture of it, we want you to be able to.
• I think the separation lines look pretty sharp, but they can be toggled off in settings.
• If you’re using this to think like a pitcher, remember that fastballs pair best with different pitches depending on where they’re located.
• Since we’re calculating a lot of pitch metrics and also location, we dynamically calculate vertical approach angle in the Pitch Metrics tab. It’s a great interactive lesson in how much plate location influences approach angle.
• Go look at Nolan McLean’s arsenal. It’s so fun – and this tool explains why he has a hell of a time commanding his curveball.

Sean and I expect to make feature updates to the Paired Pitches tool in the coming weeks and months. This version was good enough to release, but we’re still making improvements of our own. We also want to hear what improvements you’d make, so please give us feedback via the menu that pops up on every Lab page.

Batters swing slower in the cold, but I’m not sure that it matters.

Bat speed goes down when it’s cold, and it goes up when it’s hot. This is something that’s both literally true and curiously linear. We can see in the plot below that bat speed climbs bit by bit as temperature rises from chilly to toasty:

My first thought is this makes sense. It’s reasonable to assume batters don’t swing as fast when their muscles are stiff and their hands are numb. I’ve been cold before, and yeah, it’s difficult to perform tasks requiring fine motor skills.

My second thought is I’m skeptical. Notice the scale of the plot. All that movement amounts to about 0.6 mph from the coldest games to the warmest games. Lots of things other than temperature could be driving this relationship. Bat speed goes down with velocity. Velocity goes up with relievers. Relievers enter games late. Temperature goes down at night. You can see how this could get tricky.

Let’s build a model. Read the rest of this entry »

Mostly, we treat the Los Angeles Angels like the friend whose life is a wreck but there’s nothing you can do about it because they’ll never ask for help and won’t take advice. So you just check in on the AL West standings every so often and feel a combination of pity and helplessness.

Well, you can take your pity and shove it, because as I write this the Angels are in first place in the division. Tied for first place, at one game over .500, but it still counts. Much as Jo Adell’s three-robbery night on Saturday won fawning headlines, and much as Zach Neto’s four home runs are leading the offense, there is one man driving this train: José Soriano.

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 »

This isn’t how they drew it up on the North Side this winter. The Cubs won 92 games in 2025, and then they made some additions in the winter. The Brewers, meanwhile, subtracted. Chicago had the best playoff odds of any team in the NL Central, whether you’re talking about our odds, PECOTA’s odds, or pretty much any projection system you can name. The Cubs had exciting rookies, battle-tested veterans, and fun vibes. Surely, they’d sail through 2026.

Nearly two weeks into the season, it’s fair to say that things haven’t gone according to plan. There’s the standings, for one thing: They’re in last place in the NL Central. But this early in the year, only four games separate first and last in the division, so that’s not the biggest problem in Wrigleyville. A bigger concern is that Cade Horton and Matthew Boyd, two of Chicago’s top starting pitchers, hit the IL on consecutive days. Seiya Suzuki hasn’t appeared yet this year, though he’s expected back on Friday.

Horton’s injury looks to be the worst of the two. He left last Friday’s start after feeling forearm discomfort, and after getting some scans over the weekend, he’s seeking a second opinion from Dr. Keith Meister. That ominous turn of phrase doesn’t guarantee a long-term injury, of course, but it’s definitely not a good sign. Pitchers don’t generally seek second opinions from famous surgeons unless there’s a decent chance of surgery.

Boyd was supposed to be the safe option in the Cubs rotation. We had him down for the most innings and the most WAR, the staff ace. His bicep strain might not be all that bad; he noted that he could have pitched through the injury if it weren’t so early in the year. But that’s not really the nature of pitcher injuries, in my experience. Sure, sometimes they’re short. But a guaranteed minimum stay doesn’t exist. I think it’s reasonable to be worried about Boyd’s prognosis until he’s back on a major league mound, even though he seems likely to return far sooner than Horton. Read the rest of this entry »

Mark Grant is one of the game’s most entertaining color analysts. Teamed with play-by-play announcer Don Orsillo, the man affectionately known as “Mud” is a big part of why the San Diego Padres TV booth polled as baseball’s best in Awful Announcing’s 2025 local broadcaster rankings. Now in his 11th season alongside Orsillo, Grant first began working Padres games in 1996. His previous partners in the booth include the legendary Dick Enberg.

Grant was a pitcher prior to becoming a broadcaster, toeing the rubber for six teams across the 1984-1993 seasons, including the Padres, with whom he made 126 of his 233 appearances. All told, he went 22-32 with eight saves and a 4.31 ERA over 638 2/3 innings.

How well does he remember his matchups against certain batters he faced? As I’ve done previously with David Cone, Mark Gubicza, and Jeff Montgomery — those pieces can be found here, here, and here — I decided to find out by challenging him to a career quiz. Not only did he oblige, he supplied fun anecdotes along the way.

I began by asking the pitcher-turned-broadcaster which batter he faced the most times. Read the rest of this entry »
