Hello. While on paternity leave, I kept a journal about baseball and my daughter, who is not named Derek Jr., but who will henceforth be referred to as Derek Jr. You can read all of the entries here.

Derek Jr. and I will be on our own for much of the day. My wife is planning on meeting up with a friend for a walk in the park, taking an hour-long call, and then spending a couple hours editing her novel. Things go beautifully at first. Derek Jr. naps for nearly three hours in the morning, during which time I do a little writing myself. I feed and change her when she wakes up, but the effort of having someone else feed and clothe her seems like it’s already tuckered her out. Such is the life of a baby.

I put her right back down to sleep and try to nap in the room with her, but I can’t sleep. My brain is still whirring from the writing I did earlier. So I grab the monitor and take a crack at mixing a children’s song I’ve been working on. It’s the last thing I recorded before Derek Jr. was born. Fittingly, it’s called “I’m Sleepy.” Read the rest of this entry »

The concept of trade likely predates written history. If one person has a thing, and another person has a different thing, you better believe that they’re both thinking about whether they’d be better off by swapping those things. That means that the concept of value is almost as old; if things can be swapped, then it’s important to rank them so that you don’t make a bad deal and end up with something worse than what you started with. In other words, trade value lists are one of the things we humans have done the longest. Or at least, that’s what I like to tell myself to feel better when it’s 11:47 PM and I’m wondering whether I’d rather have four years of a shortstop or three years of a mid-rotation starter.

Welcome to the 2026 FanGraphs Trade Value Series. Starting today and continuing through the end of the week, we’re releasing our list of the 50 most valuable players in baseball, taking player performance, age, and contract details into account. Dave Cameron, Kiley McDaniel, Craig Edwards, and Kevin Goldstein have all headlined this list before; this is my fifth year doing it on my own.

Of course, I really ought to put “on my own” in quotation marks. I start building this list by gathering every input I can think of. Age, contract status, current statistics, projected future performance, Statcast data, pitch- and arsenal-level modeling, scouting reports – if it can be written down, I try to consider it in my first pass. I use all of those inputs to come up with an initial set of rankings, then refine those rankings by diving deeper into individual player comparisons. After I have things in relatively good order, I consult with the FanGraphs staff to clarify my thinking further and get new opinions on tough decisions. Everyone is a big help, but special thanks are due to Dan Szymborski for supplying the ZiPS projections, Sean Dolinar for his technical assistance, and Meg Rowley for patiently shepherding the project from a spreadsheet to the final product. Next, I reach out to sources on the team side. Here, I try to gather perspectives from organizations with different methodological leanings, budgets, goals, and places in the competitive cycle; basically, as many differing viewpoints as possible.

Ben Lindbergh and Meg Rowley banter about Ben’s jury duty and his reaction to Meg and Craig’s pillow talk on the preceding episode. Then they discuss why All-Star Game pitching is overpowering, whether the Home Run Derby balls were juiced (and whether it matters), another earliest-ever Opening Day, MLB’s crackdown on teams’ boundary-pushing use of dugout iPads, Shohei Ohtani’s pitching pause, MLB app complaints, extensions for Chase Burns and Kyle Bradish, Luis Arraez as a prize of the trade deadline, and the funniest tech startups the Dodgers have seeded.

Troy Melton has excelled since returning to the mound in late May. Over nine starts comprising 55 innings, the 25-year-old Detroit Tigers right-hander has won five of six decisions while logging a 1.80 ERA and a 3.86 FIP. Sidelined for the initial two months of the season due to elbow inflammation, he is back to being one of baseball’s most-promising young pitchers.

What most stands out about Melton’s campaign to date? From an arsenal perspective, the answer has to be his cutter. Last season, he threw the pitch at a 10.8% clip to the tune of a .368 BAA and a 12.8% whiff rate. This year, the offering has elicited a .083 BAA and a 26.0% whiff rate while being thrown at a nearly-double 20.5% clip.

Why the increased reliance on his cutter, and why has it been so effective?

“I didn’t really change anything, which is the weirdest part,” Melton told me in the days leading up to the All-Star break. “I’ve just been throwing it way, way harder and getting a lot of swing-and-miss. I’ve been throwing my slider harder, too. I got one up to 91 [mph] in my last start, which is well above what I’d been doing previously.

“It’s definitely interesting,” the second-year big-leaguer continued. “It’s not even something I consciously changed, it’s just that I’ve had a little bit more intent. I realized that my intent wasn’t high enough, so I literally started trying to throw harder, and that didn’t sacrifice any execution. I’ve been executing just as good, if not better. My cutter has been kind of been the leading beneficiary of that.”

In terms of velocity, Melton’s cutter is averaging 92.2 mph, up from 90.9 mph in his rookie campaign. Locating the pitch better has likewise been a factor in its success, as has its role in his attack plan. Read the rest of this entry »

I’ve been thinking a lot about the baseball calendar in recent days, specifically how we use it to both mark the passage of time and look ahead to the possibility of what’s yet to come. As fans, we slice up the season to make it easier for us to discuss noteworthy performances, evaluate trends, and justify our irrational faith that our team just might turn things around. As analysts, we know that we shouldn’t draw grand conclusions from these individual slivers — the sample sizes are just too small — but we also recognize the benefits of using these otherwise arbitrary segments to understand the season as it unfolds.

I mention all of this because this weekend is start of the second half of the season. Of course, we all know that the All-Star break hasn’t been the season’s true midpoint for some time now, as Opening Day is scheduled earlier in the year than it used to be while the All-Star Game continues to be played on the second Tuesday of July. Even so, there are three reasons that I continue to find value in splitting up the season in mid-July. First, pausing the regular season for a few days provides a natural demarcation point. Second, with playoff field now expanded to 12 teams, the postseason lasts longer than ever before. Because the team that wins the World Series could play up to 22 additional games, the All-Star break ends up being much closer to the halfway point on the journey from Opening Day to the decisive game of the Fall Classic. Finally, the three-week stretch after the All-Star Game is a frenetic rush to the trade deadline that then rolls right into the Dog Days of August and the strenuous sprint of September. The games after the All-Star break are much more demanding than the ones before it, thus making the few days of respite in July feel like a more representative dividing line than Game 81 in late June.

Anyway, in this first mailbag of the second half, we’re answering your questions on what it would be like if MLB had a loan mechanism like professional soccer, Kyle Karros’ breakout, the longest time a team has spent within a half-game of .500, and what Anthony Rendon’s career might have been. But first, I’d like to remind you that this mailbag is exclusive to FanGraphs Members. If you aren’t yet a Member and would like to keep reading, you can sign up for a Membership here. It’s the best way to both experience the site and support our staff, and it comes with a bunch of other great benefits.

In years past, I’ve generally addressed the teams receiving less-than-acceptable production in one corner outfield spot or the other within the same post, but this year’s batch of right fielders is disproportionately large, mandating a separate entry that led me to combine the left and center field lists instead. There’s still some crossover between most teams’ pools of right fielders and the positions I covered in the previous post, with a couple teams from this group landing on both lists. As they look to upgrade, there’s some fluidity as well, with teams willing to test the defensive limitations of their outfielders in order to shoehorn better bats into the lineup.

While still focusing on clubs that meet the loose definition of contenders (a .500 record or Playoff Odds of at least 10%), and that have gotten about 0.6 WAR or less out of a position thus far (which prorates to 1.0 WAR over a full season), I’ve also incorporated our Depth Charts’ rest-of-season WAR projections into the equation for an additional perspective. Sometimes that may suggest that the team will clear the bar by a significant margin, but even so, I’ve included the club here because its performance is worth a look.

As noted previously, some of these situations are more dire than others, particularly within the context of the rest of a team’s roster. As always, I don’t expect every team here to go out and track down upgrades before the August 3 trade deadline, but these are ones to keep an eye on. Read the rest of this entry »

Hello. While on paternity leave, I kept a journal about baseball and my daughter, who is not named Derek Jr., but who will henceforth be referred to as Derek Jr. You can read all of the entries here.

May 18
The summer after my wife and I moved in together, we had a mouse in our apartment. We set traps everywhere we could think to put them, but no matter what kind of traps or bait I used, the mouse wanted nothing to do with them. After a couple days, I got desperate. I wanted to figure out exactly where the mouse was getting in so that I could close up the gap to keep it out. Failing that, I wanted to figure out where it was going so that I could set traps in the right places. So I propped up an iPad against the arm of the couch with its camera pointed at the kitchen, called it on FaceTime from my laptop, and brought the laptop into the bedroom and closed the door. Then I sat quietly, stared at my kitchen from the other room, and waited for the mouse to show up. Even as I was setting everything up, I recognized it as an act of madness. But it worked.

I didn’t glean much that first day. If I recall correctly, the mouse did eventually show up, but it turned out that the iPad didn’t have a good angle on its movements. I couldn’t tell where it was coming from or where it was going, only that it crossed the kitchen a time or two. Convinced that the concept was sound and the execution could be improved upon, I tried it again the next day. My wife was off work, so I explained that I needed her to hole up in the bedroom with me. She recognized it as an act of madness too, but she found it hilarious. She dubbed it Mouse TV, and she understandably shrieked when the mouse finally showed up. We watched and stifled our laughter as it nosed around the kitchen. It took a couple more days of Mouse TV to figure out where the mouse was coming from, plug the hole, and make sure that the mouse wasn’t coming back. My wife was tickled the whole time. Whereas I felt embarrassed and vaguely unclean about having a rodent in my home, she’d tell the story of Mouse TV to anyone who could listen. It has, somehow, become a fond memory.

Welcome to Because You Asked, a series in which I’ll dive deeper on some of the players who readers inquire about in my weekly chats. These tend to be guys who were absent or only briefly mentioned on our last list cycle, or players with production that’s out of step with their reputation or scouting reports. Also, Jonah Tong. Hopefully this exercise allows me to just tap a sign every week instead of writing the same sentence or two; we’ll see how it goes. First up: Manuel Pena.

Pena is a 22-year-old utility prospect in the Diamondbacks system. We’ve written about him before — Eric and I ranked him 15th in Arizona’s system in 2022 as a projectable power hitter — but he quickly fell out of the main section of lists and was absent entirely during our last three cycles. This year, Pena has started games at first, third, and second base, as well as in left field, and while he has a little shortstop experience on his CV, he’s primarily a four-corner guy at this point. Nobody’s asking about the glove, though. Pena has drawn attention for one reason: Out of nowhere, he’s among the minor league leaders in home runs with 29. This comes after he’d hit 31 in the previous five seasons combined, so fans and readers understandably want an update here. Read the rest of this entry »

Something significant happens to Chase Burns around this time every year. In 2024, the Reds made him the no. 2 overall pick in the draft. A little less than 12 months later, the former Wake Forest flamethrower made his big league debut. This summer, Burns was named to his first All-Star team, paving the way for a seven-year, $105 million contract extension.

Burns’ new contract kicks in next year and runs through the 2033 season; and in a rare occasion for a pre-arbitration extension like this, there are no opt-outs, options, or escalators. Thank God — you need a degree in discrete mathematics to know how long Julio Rodríguez is under team control, so a simple contract structure is a refreshing change. Read the rest of this entry »

The All-Star break affords a good opportunity to run a full update of the ZiPS projections, since the lack of action allows me, the system’s flesh-and-blood creator, the time to refresh every speck of data that ZiPS uses before new games push over my tower of dominoes.

The ZiPS projected standings are the product of a million seasonal simulations; there’s a lot of PC power and a unfortunate amount of linear algebra involved. In order to get a better estimate of the upside and downside of a team, ZiPS takes the important additional step of simulating the roster itself before it ever considers a single game on the schedule. To illustrate, in most of the million simulations, Yordan Alvarez continues to treat opposing pitchers in a rather rude fashion, and sometimes, he even wins the Triple Crown. But in some simulations, he’s merely OK, while in others, he misses time due to injury. In a small percentage of those runs, the injury proves significant and prematurely ends his season. When a player is injured in a ZiPS simulation, the computer fills in the depth charts based on who is left standing. While this isn’t a perfect approach, the overall effect is to give us a range of expectations for the Astros, allowing us to peek as far as as we can into the future until the future actually arrives.
