FanGraphs Baseball

Saberseminar is a leading baseball and sports analytics conference — and it’s all for a good cause. The conference will take place August 29-30 at Illinois Tech in Chicago. Saberseminar brings together academics, data scientists, and MLB front office employees for a two-day showcase of the latest developments in baseball analytics, and it’s a great chance for researchers to show off their work in front of an audience of teams and vendors that are looking to hire. It’s also a place to network and build community across the industry, whether it’s with fans, reporters covering the game, scientists studying it, or front office personnel. FanGraphs has been a supporter of Saberseminar for over 10 years, and several members of our staff will be in attendance. Proceeds from the conference support the Alliance to Cure Cavernous Malformation and the Young Center for Immigrant Children’s Rights.

We hope you’ll consider attending. Tickets are on sale now, with a large discount for students. For more information, please visit the conference website. We hope to see you there!

Three interviews — two with pitchers, another with a hitter — were published here at FanGraphs over the past week. All were the result of lengthy conversations, and in each case, worthwhile snippets landed on the cutting-room floor. This week’s column will lead with those leftovers, which come courtesy of Drew Rasmussen, Cole Sulser, and Pete Alonso.

We’ll start with Rasmussen, who addressed his ability to command his offerings, particularly his four-seam/two-seam/cutter combination.

“Command is kind of a sliding scale,” said the Tampa Bay Rays right-hander, whose 4.3% walked rate ranks lowest among qualified hurlers. “Some days it’s really good and some days it’s not so good. The job is to figure out what you have as quickly as possible. On days when my command is really good… I would say that is situation-driven. If I need a ball on the ground, I can throw it with a little more tail and a little less carry. If I’m just trying to steal strike one, maybe I don’t want the [movement] profile to be as big; that way it has a better chance of staying in the zone.

“Conversely, on days that I’m not overly confident with my command, I simplify to the absolute max,” he continued. “We’re going to try to just throw the same one over and over again. Then, hopefully at some point over the course of the outing, something clicks and I start to get more and more confident, and comfortable, with the command I have that day.” Read the rest of this entry »

Ben Lindbergh and Meg Rowley banter about a Donald Trump claim about Shohei Ohtani, José Caballero’s battle with MLB about his pre-pitch routine, Yandy Díaz spurning ABS, James Wood’s impressive results with a seemingly suboptimal approach, whether the Nats would be better off if they hadn’t traded pitching prior to the season, David Rubenstein’s Orioles optimism, and Corbin Carroll’s triples pace. Then (1:04:45) they talk to EW listener Jacob Redmon, who found himself at the center of a viral video this week when he was slapped by a man who objected to his staying seated during the National Anthem, about how the incident developed, what the video didn’t show, and what he took from the experience. Finally (1:57:33), Ben talks to Kenny Lofton about his exclusion from the Hall of Fame, his Cooperstown-caliber career, and his outlook for induction.

Controversy surrounding José Caballero’s pre-pitch routine struck twice in the Bronx this week, with the first time prompting the benches to clear and the second causing unnecessary confusion. In the eighth inning of the Yankees’ 8-5 win over the Pirates on Monday night, Caballero did what he usually does — he dug into the batter’s box and didn’t look up at the pitcher until there were eight seconds left on the pitch timer. The idea is to disrupt the pitcher’s rhythm. Pittsburgh reliever Dennis Santana took exception to Caballero’s tactic — which, again, he has done many, many times for the last four seasons — and yelled at him after getting him to ground into a double play. The benches emptied, and the Pirates complained to MLB about it.

Turns out, the griping worked. After the game, the league told the umpires to more strictly enforce the rules requiring batters to engage with the pitcher with no fewer than eight seconds left on the clock. Instead of warning the batter, and then calling an automatic strike for a repeat violation, the umpires were directed to assess a strike to Caballero for attempting to deceive the pitcher, no matter how much time was left on the pitch timer. Both Caballero and the Yankees claim the league did not notify them about the change. As crew chief Adrian Johnson told a pool reporter after, “He’s been warned all season. We were instructed not to warn him. We were instructed to violate him. That’s what it is. It’s a violation.” Along with Johnson’s poor phrasing, the sudden change in enforcement is quite jarring and, in my opinion, inappropriate. If what the Yankees said is true — that the league didn’t tell them about the change — then I think this is an overstep by MLB to single out a player. Caballero accused the umpires and the league of “picking on” him. But even if MLB did give the Yankees and Caballero the heads up, I think the escalated enforcement is an incorrect interpretation of the rule. I love that Caballero uses the pitch clock to his advantage; pitchers can hold the ball and run down the clock to zero, so why shouldn’t batters be allowed to wait their full allotted time before engaging with the pitcher? Moreover, I also don’t know how Caballero is deceiving the pitcher by doing something he does so frequently. He’s certainly trying to annoy the opposing pitcher, but that’s not deception — that’s good gamesmanship.

Anyway, that’s the last you’ll read about Caballero in this week’s mailbag. Instead, we’ll be answering your questions about Esmerlyn Valdez’s heater, Gunnar Henderson’s woes against fastballs, how to fix the Angels, and whether anyone will break Jesse Orosco’s record for games pitched.

They might still play in a minor league ballpark, but things were looking up for the Sacramento-ish Athletics coming into the 2026 season. The franchise hadn’t had a winning record (and typically hasn’t even been close) since 2021, with their last stretch of playoff relevance ending after the COVID-shortened 2020 season. The 2025 A’s only went 76-86, but an offensive core of Nick Kurtz, Shea Langeliers, Brent Rooker, Tyler Soderstrom, and Jacob Wilson seemed to give the club a good chance to score runs this year. The A’s entered the season with 21.4% playoff odds, their best in some time.

The team’s most plausible breakout scenario involved leaning on a good offense while cobbling together just enough pitching to keep from being on the short end of a bunch of slugfests. The A’s were even confident enough to be on the other side of a salary dump for once, picking up Jeff McNeil over the winter. Unfortunately, things haven’t gone exactly to plan. The A’s are 43-59 entering play on Friday. The offense has been middling, and though they’ve gotten a few promising pitching performances from J.T. Ginn, Hogan Harris, and Gage Jump, the staff has more holes than a wheel of Emmentaler after a run-in with a shotgun. Read the rest of this entry »

Fifty-one weeks ago, the San Diego Padres traded a king’s ransom in prospects to the Athletics in exchange for depth starter JP Sears and hard-throwing relief ace Mason Miller.

Ordinarily, I would’ve abhorred such a move. The top prospect who went the other way, Leo De Vries, came in at no. 6 overall in the Preseason Top 100 Prospects list, and in my mind there’s no more overrated commodity in baseball than team control for a reliever. What the Phillies gave up for two and a half years of Jhoan Duran, immense a haul as it seemed at the time, was a fraction of what four and a half years of Miller cost.

Still, I kind of got it. Read the rest of this entry »

As we approach August, now is a good time to take a fresh look at the farm systems of some of the clubs we expect to be buyers at the trade deadline. These teams are both contending for a playoff berth and in clear need of a significant upgrade, the kind that will likely require parting with a top farmhand or two. We’ll begin today with the Atlanta Braves. In tandem with an evaluation of the team’s needs and deadline posture, we’ve updated Atlanta’s Top Prospect list to account for the graduations of Didier Fuentes and JR Ritchie, incorporate the new draftees, and reflect a number of promising developments on the farm. If you were solely to evaluate a farm system by its performance relative to expectations, the Braves have a case for the top spot in the league, and that newfound depth looms as a key factor in the club’s playoff push.

The Situation
For a while, the Braves seemed poised to boat race the NL East. The club went 40-20 over the first two months of the season and built a 10-game lead over the Phillies. The Mets, also projected to be strong contenders in the division, languished even less threateningly in dead last. 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 21
So Jose Siri made the coolest play I’ve seen in a while. He’s on the Angels now, a fact I had missed entirely, even though I now realize I saw him pinch-running against the A’s just two nights ago. When you think about Jose Siri, you think of great center field defense (and one million strikeouts), but that great center field defense usually comes in the form of great jumps and fantastic athletic catches. Tonight, however, he racked up an out with a combination of savvy and a perfect, powerful throw. A’s right fielder Carlos Cortes hit a routine single back up the middle. There was nothing notable about that whatsoever, but the Angels must have a scouting report that says Cortes likes to take aggressive turns when he singles. Whoever wrote it deserves a raise.

Siri played the ball normally right up until the moment when he didn’t. He intercepted it at a slow jog. It looked like he wasn’t taking the threat of Cortes going for a double seriously, but what he was actually doing was baiting Cortes, while also allowing the slow route to let him field the ball with his momentum still pushing him to his left, toward first base. That way, when he came up firing behind Cortes, he was able to got everything he had behind the throw. First baseman Nolan Schanuel was clearly in on it too. He lurked in foul territory, out of view of both Cortes and the first base coach so as to avoid arousing any suspicion, then popped back onto the field in time to catch the throw and apply the tag.
