On April 21, Grant Anderson inherited a hot mess. With the Brewers ahead 3-0 in the fourth inning, starter Kyle Harrison lost his feel. He walked Riley Greene and Spencer Torkelson in two uncompetitive plate appearances, then gave up a rifled line drive on one of his slowest fastballs of the day, a center-cut cookie to Hao-Yu Lee. Pat Murphy called Anderson in from the bullpen to face the bases loaded with no one out.

Anderson delivered nearly flawlessly. He got Javier Báez to ground into a first-pitch double play, then struck out pinch-hitter Kerry Carpenter to escape the inning with only a single run allowed. That run, of course, went on Harrison’s ledger. Anderson got credit for a scoreless inning, no more or less.

On May 16, Chase Silseth tried to pull off the same trick. José Soriano fought through five strong innings against the Dodgers, but he didn’t have it in the sixth. After an inning-opening groundout, he walked four of the next five batters and hit the fifth, driving in two runs and leaving the bases loaded. Silseth came in to put out the fire – but he might as well have poured kerosene on it. He hit the first batter he faced, then gave up a two-run single immediately after, pushing the score to 6-0. He finally got the last two batters of the inning – which meant that in the game’s official log, he pitched two-thirds of an inning and didn’t allow a run.

These two pitching performances went quite differently. Anderson had a tougher task and performed better. But the two of them each got credit for a clean sheet. This is far from the only problem with the way we calculate ERA, but it’s one that stands out to anyone following. Anderson and Silseth didn’t deserve the same counting statistics there. Likewise, Soriano got tagged for three runs, while Harrison got tagged with only one. But that didn’t reflect what happened to them – both of them lost it and had to be removed from the game because of all the runners they’d allowed. Read the rest of this entry »

On Wednesday night, Gerrit Cole took his first loss since coming back from Tommy John surgery. After two starts of at least six scoreless innings, Cole got tagged for three home runs against the Guardians. Even so, it’s a promising return for the Yankees’ ace, who’s still throwing in the mid-to-upper 90s. His curveball is still curving, and while his fastball mix has evolved over his career in response to some trend or other, I’m confident he’ll find something that works. He always has.

I got to thinking about Cole in the context of a question I posed earlier this week about Adley Rutschman: Who’s the best draft prospect of the 21st century? Who presented the best combination of high floor and elite upside? The answer to that question is probably not Cole; if you were going for a workhorse college starter, you’d pick Mark Prior, Stephen Strasburg, or Paul Skenes. Or maybe even Carlos Rodón. But Cole definitely fits the bill; there’s a reason he was the top pick in the best draft class of the past 15 years. Read the rest of this entry »

Reid Detmers has saved his career — again.

Detmers, if you weren’t aware, is a top 10 starting pitcher to this point in 2026. He has accrued 2.0 WAR, which is slightly more than Chris Sale, Max Fried, and Jesús Luzardo. If it weren’t for Cristopher Sánchez, Detmers might have a case as the best lefty starter in baseball right now. He’s also been the Angels’ best pitcher, even a step ahead of José Soriano, who burst onto the national stage with a red-hot April before cooling in recent weeks. Detmers has kept plugging away, quietly — surprisingly — excelling in the background.

If you’d told me in 2022 that Detmers would be a top 10 starter in baseball by 2026, I would have said, “Sure, that sounds reasonable.” That was his first “full” season in the majors, and he posted a 3.79 FIP with fine peripherals. Yes, he got sent down for about a month in the summer to work on some things, but it was a solid rookie season overall. He even showcased his ceiling with a no hitter that May.

It’s what happened in the seasons that followed that makes this one of the most unexpected early performances of the year. Detmers didn’t improve in 2023. He struck out more batters, which is good, but he developed a pesky command issue that resulted in more walks and home runs. And things got worse in 2024. He again boosted his strikeout rate, and he again gave up more walks and home runs than he had the year before. By June, the Angels had seen enough and sent him down to Triple-A. They recalled him in September for five final starts, and when he returned? Even more strikeouts, even more walks, and even more homers. 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. This is the second installment of that series. You can read all of the entries here.

April 17

Like any new parents, my wife and I spend a lot of time staring at our baby and talking about how beautiful she is. Of course we do. Evolution has programmed us to be completely overwhelmed by the baby’s beauty so that we don’t leave her on the doorstep of the nearest convent when we get fed up with the wailing and the sleepless nights and the relentless, unceasing, never-ending pooping. It has worked. We are ensorcelled. Derek Jr.’s future is wimple-free. But I’m starting to think it has hit my wife harder.

I say this because she has started to insist that Derek Jr. is “an objectively beautiful baby.” Objectively beautiful. You’re familiar with beauty, right? The thing that is, famously, in the eye of the beholder? Apparently one beholder knows better. It’s not enough that she thinks the baby is beautiful, and that everyone tells her all day long how beautiful the baby is. She now needs it to be proven empirically.

I used the word “insist” earlier because I have been pushing back ever so slightly on this one. I spend a whole lot of time analyzing players or trends, and it requires rooting out biases and confounding variables. Call me crazy, but I’m picking up on a possible conflict of interest here. I’m not prepared to get in a fight over this, but I have gently pointed out that the fact that my wife is throwing around the word “objectively” here is — objectively — hilarious.

Erik Tolman has a remarkable backstory. Currently playing for the Triple-A Rochester Red Wings, the 26-year-old left-hander threw to one of baseball’s most prolific pitchers as a prep, and that is a comparatively insignificant part of his past. His level of perseverance is nothing short of remarkable. Tolman has overcome debilitating injuries on his journey to the doorstep of the big leagues.

His travails began in 2021, the year the Washington Nationals drafted him in the 14th round out of Arizona State University. He had the first of two Tommy John surgeries, costing him all but three games in his final collegiate campaign — and his bad fortune was only just beginning.

“I tore my UCL again at the end of my rehab,” Tolman explained. “Fourteen months after having surgery, in my last live ABs, I felt my elbow go again. It was a sad moment, honestly. But I talked to my family, and I believed in myself — I thought I could still be a big-leaguer — so I kept at it. Unfortunately, on my fifth start back, in August 2023, I dislocated my knee. That made for a whole new mountain that I’ve had to climb.

“The injuries have driven me to have a work ethic, and a mental fortitude, of just going balls to the wall,” he added. “I figured I could either struggle coming back from the injuries, playing baseball, or struggle out in the real world. At the end of the day, we’re the ones responsible for our lives and careers. If you get hurt, are you going to cave, or are you going to overcome?”

Tolman did far more than simply dislocate a knee after returning from the second TJ. What happened was not only catastrophic: it was hard to fathom. Read the rest of this entry »

The best team in baseball will be without its biggest star for a few weeks.

The Braves placed Ronald Acuña Jr. on the injured list Sunday with a strained left hamstring. Acuña exited Saturday’s game after pulling up in considerable pain while running out a groundout. Manager Walt Weiss told reporters that imaging revealed a Grade 1 strain, the least severe grade. According to MLB.com, Weiss said:

“It’s not going to be just a couple days. It’s gonna be more than that, so we need to put him on the IL, and hopefully it’ll be sooner than later. No idea with these soft tissue injuries how long they’re gonna take, but I think the silver lining is that the MRI showed it wasn’t too serious.”

While many players return from Grade 1 hamstring strains in just a couple weeks, or even following the 10-day minimum, this is an injury that can linger and delay a return.

This is, obviously, less than ideal for the Braves. Acuña is their best player and was projected in the preseason as the ninth-best position player in baseball with 5.4 WAR, according to our Depth Charts. Though his performance hasn’t been spectacular thus far, with a 111 wRC+ in 152 plate appearances, his .381 xwOBA and 12.2% barrel rate — along with strong strikeout and walk rates — suggest he hasn’t missed a beat this year, coming off his bounce-back 2025 season.

Of course, last year was a comeback campaign because Acuña missed most 2024 (and the early part of 2025) after tearing his ACL. He also missed chunks of 2021 and 2022 with a torn ACL in his other knee. In 2018, he missed about a month with a mild ACL sprain. That means Acuña’s hamstring strain is his fourth lower body injury requiring IL time in his career. Read the rest of this entry »

A question popped into my head as I edited Ryan Blake’s column on the Nationals Friday morning. In the piece, shortly after noting that James Wood ranked third in the majors with a 170 wRC+, Ryan mentioned that Wood’s teammate, CJ Abrams, was sixth with a mark of 168. Upon reading this, I pulled up our leaderboards to see if the Nationals were the only team to have two players in the top 10. Turns out that, yes, they are. I thought about that for all of two seconds before something else caught my eye. Just below Abrams on the list was Mike Trout, who also had a 168 wRC+. This prompted me to wonder: Can Trout return to form? Can he both stay healthy and produce this year?

I’m hardly the only one who spent the bulk of the 2020s dreaming on a fully healthy season from Trout, just as I’m not alone in having abandoned that hope as the injuries piled up. But after watching him blast home run after home run last week from the Yankee Stadium pressbox, I felt the pull of the past encroach upon the present, and perhaps against my better judgment, I started dreaming again. He sure looked as healthy as ever as his broad body barreled up baseballs and roamed center field. The best way to describe the way Trout moves — really, the way he has always moved — is that he lumbers and boulders; for all of his natural athleticism and breathtaking blend of speed and strength, he does not glide gracefully. I put that dream of a Trout renaissance on ice when the Angels left town, only for it to come back a week later. This time, though, I considered whether, at 34, he still has one more MVP season in him. He entered this weekend slashing .239/.417/.557 with eight home runs, and has posted 1.2 WAR in 25 games. He’s walking more than he’s striking out, and he’s already stolen four bases. His BABIP is a mere .228, 111 points below his career mark, so we should expect his batting average to see some positive regression. (Even if we know batting average isn’t all that indicative of player performance, it still matters for MVP voters.) His .483 xwOBA is second in the majors and 62 points above his wOBA. His defense has been below average so far, but if Trout keeps hitting like this, his glove won’t matter much for his MVP case. The narrative would certainly be in his favor.

I just answered two of my own questions from Friday in this mailbag, so I guess it’s time to get to yours. What if the Astros blow it all up? How might the Pirates benefit from a Houston fire sale? Why don’t teams develop bench players to be knuckleballers? What the heck was Austin Warren doing in the game with the bases loaded in the Mets’ 12th straight loss? We answer all these questions and more in this week’s mailbag. Plus, Jay Jaffe remembers Garret Anderson. But first, I’d like to remind you that this mailbag is exclusive to FanGraphs Members.

George Klassen’s initial big league outings were clunky. He allowed seven runs in just 4 2/3 innings over a pair of April starts, which, combined with an index fingernail contusion, has him back at Triple-A Salt Lake for more seasoning. That doesn’t mean his future isn’t promising. The 24-year-old right-hander ranks second on our Los Angeles Angels Top Prospects list, and 57th on our Top 100. Moreover, he was described by Brendan Gawlowski as having “some of the best stuff in the [Angels] system.”

An inability to consistently land his plus stuff in the strike zone is currently Klassen’s bugaboo. He issued free passes to 10 of the 32 batters he faced in his two starts in the majors — one against the Reds, another against the Mariners — and while big league jitters were certainly a factor, George Kirby he’s not. As Gawlowski wrote in his scouting report, “Klassen’s command remains below average… [and] there are markers in his delivery that suggest his feel for location will likely remain crude.”

A few years ago, Klassen was Mitch Williams-wild. As Eric Longenhagen pointed out in November 2024, the West Bend, Wisconsin native walked nearly a batter per inning in his 2023 draft year at the University of Minnesota. But as our lead prospect analyst also noted, “his feel for the strike zone improved right away in pro ball.” That was in the Phillies system. The Angels later acquired the erstwhile sixth-round pick from Philadelphia in the July 2024 Carlos Estévez deal. Read the rest of this entry »

I made it out to Everett a couple of times last week, drawn by the chance to watch three of our Top 100 prospects and a couple of other notable farmhands. My thoughts on seven of the standouts are below.

Tyler Bremner, RHP, Angels
Bremner was as advertised. He’s a loose athlete with, odd front leg swing as he starts his motion aside, a clean and easy delivery. He ticked every number on the gun from 93-98 mph, flashed an above-average slider, and most importantly, missed a half dozen bats with his 70-FV changeup. On the night, he struck out four, walked three, allowed one hit, and only one or two hard-hit balls. It’s what an early first-round pick should do against a decent High-A lineup.

If we’re going to pick nits, I wouldn’t focus on the walks too much, as Bremner was battling a muddy mound on a cold night. He nibbles a bit and likes to entice hitters off the plate. He does this on the changeup especially, and it’s fair to wonder if big leaguers will bite to the same degree college and low minors hitters have thus far. Despite the velo, he only missed two bats with the fastball and none with the slider, which raises questions about where he’ll turn on days when hitters aren’t chasing the cambio. Ultimately, I don’t have long-term concerns. He still projects as a no. 3 or 4 starter, but the night underscored the importance of continuing to develop his slider and fastball command. Whether that’s a job best done at this level or a rung up is above my pay grade.

Jonny Farmelo, CF, Mariners
Farmelo put together two solid at-bats against Bremner. He didn’t reach base, but managed to turn around an upper-90s fastball up and in and line it to right in his first trip up, and then hit a hard line drive to left in his second plate appearance. He got out in front of fastballs a couple times this week and showed enough barrel manipulation to stay competitive on pitches up, even with his fairly long bat path. Perhaps most encouragingly for a player who has battled a lot of injuries as a pro, he still looks like a 70 runner, and he also made a nice read and leaping catch at the wall in center.

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.
