SEATTLE — Every year, pitchers and catchers report for spring training, and just as spring represents a reawakening in the natural world, spring training provides a reawakening for every team, a fresh start, full of renewed optimism. No matter the team, fans across the league allow themselves to dream a little, to believe that this year might be the one.

You could be my silver springs
Blue-green colors flashin’
I would be your only dream
Your shining autumn, ocean crashing.

But for 29 teams, the season will end in heartbreak. For some teams that heartbreak might come as early as June or July, for others in August or September, and a few will experience the agony of October sorrow. Over the last several years, the Seattle Mariners have unwittingly built a tradition of remaining very much in the playoff hunt until the final week of the regular season, only to miss the cut by a harrowingly thin margin. They did make the playoffs in 2022, ending a 20-year postseason drought, but they struggled to cross that threshold again. Instead, they fell into a familiar rhythm, playing hard until the very end, but then their season was over. Their time was up.

Time cast its spell on you, but you won’t forget me
I know I could have loved you, but you would not let me.

This season is different. The Mariners not only secured a place in the postseason, but they also won the AL West for the first time since 2001. In doing so, they eschewed the Wild Card Series and advanced directly to the best-of-five Division Series, which begins on Saturday against the Tigers in Seattle. And all it took was a little witchcraft. Read the rest of this entry »

They say that in order to thrive in stressful and uncertain times, the key is to focus on the things you control. And who are “they” exactly? Mostly people who traffic in self-help cliches on the internet. But cliches are cliches for a reason. They’re rooted in some measure of truth. And in a decisive Game 3 on Thursday, the NL Wild Card Series between the Cubs and Padres was ultimately decided by control — in nearly every sense of the word. The type of control that refers to whether a pitcher can find the strike zone, the type of control a manager exercises over bullpen usage, and the type of control exerted over batted ball outcomes when lockdown defense becomes a critical component of a team’s identity.

In a 3-1 Cubs victory over the Padres, neither team looked dominant, but Chicago dominated the variables within its control, while San Diego seemed to be pulling blocks from a Jenga tower on an inning-by-inning basis and hoping to stay upright until its offense could break through with a few runs.

On July 8, the Tigers had 59 wins, while the Guardians had just 42. With one week remaining in the regular season, the Tigers have 85 wins and the Guardians have 84. A single game separates the two teams in the race for the AL Central title, a division that seemed all but sewn up for the Tigers as recently as September 13, when Detroit’s odds to win the Central sat at 98.2%, putting Cleveland’s odds at 1.8%. As of this writing, the Tigers are still favorites to win it, at 62.7%, but given that three of Detroit’s last six games are against Cleveland, the error bars on those odds are huge.

That wild swing in divisional odds happened over the course of the last week, but such a dramatic swing could only occur because in the two months leading up to it, two teams that had been heading in opposite directions both gradually rerouted and wound up on a collision course. Through April 25, both teams were winning games at roughly a .600 clip, but their fates diverged from there. By July 8, the gap in winning percentage had widened to 167 points, which translated to an additional 17 wins for the Tigers compared to the Guardians. Ever since July 8, that divide has slowly evaporated, and now the two teams own nearly identical records. Read the rest of this entry »

In the eighth inning of Wednesday’s 7-5 loss to the Orioles, Padres reliever Mason Miller threw an immaculate inning — nine pitches, three strikeouts. Immaculate innings are rare, but not that rare. Since 2005, we’ve seen 63 immaculate innings in the majors, so around two or three per season. Miller’s is the fourth of 2025, after Cal Quantrill on May 18, Brandon Young on July 8, and Andrew Kittredge on August 6. Immaculate innings are a special treat we get to enjoy from time to time. They happen infrequently enough that they do genuinely feel special, but not so infrequently that every single one demands an article memorializing the event.

Another special treat that I’ve enjoyed recently is attending a concert with my best friend. We don’t live within driving distance of one another, so due to logistical barriers, we’ve only done this four times in the last 10 or so years. So like an immaculate inning, it’s a cool thing that doesn’t happen very often. What makes our concert history extra special is that twice now touring artists have scheduled shows on my birthday — Tame Impala’s Currents Tour in 2016 and Weird Al’s Bigger and Weirder Tour this year. And what makes Miller’s immaculate inning extra special is that he threw nothing but sliders. Trust me, you’ll see how these two things are connected in a minute, but first more about all those sliders.

If you know anything about Mason Miller, it’s probably that he fires fastballs past hitters at roughly 2,700 giga-miles per hour, which means you know that his primary pitch is not a slider — it’s his fire-breathing fastball. This season Miller is throwing his slider around 45% of the time and his fastball the other 55% of the time, with the very occasional changeup sprinkled in. In his major league career, Miller has appeared in 146 innings in which he has faced at least three batters. He had not gone Oops! All Sliders in any of them prior to Wednesday. And he only topped 65% sliders in four of those innings. His next-highest single-inning slider ratio is 85%, thrown in the final inning of a start against the Mariners in May of 2023. His slider-heavy final frame was the capper on a seven-inning no-hit outing. Read the rest of this entry »

On August 20, Paige Bueckers, rookie for the WNBA’s Dallas Wings, dropped 44 points against the Los Angeles Sparks, the most ever scored by a rookie in a single game. When Bueckers passed the previous single-game rookie scoring record (40 points, set by Candace Parker, who won MVP that year), one of the broadcasters remarked that her performance in the game effectively guaranteed her Rookie of the Year honors. Heading into the season, Bueckers was favored to win the award, but strong play from Washington Mystics rookie Sonia Citron forced WNBA analysts to reconsider what once had felt like a foregone conclusion. Bueckers needed the 44-point game to reclaim her place as the sport’s top rookie.

In the WNBA’s 40-game season, one game can legitimately swing an awards race, especially in the context of a sport where a star player can dominate a game and a point guard like Bueckers touches the ball on every possession. To find an analog in a 162-game baseball season, one might have to look for a hot streak spanning several games or a particularly close race that features a game with enough narrative heft to sway the sensibilities of the writers voting on the award. Looking back at recent rookie seasons reveals a few possible examples. Read the rest of this entry »

Though many predicted heading into the 2025 season that the Orioles’ weak starting rotation and general inactivity over the offseason would come back to haunt them, even Baltimore’s biggest skeptics weren’t prognosticating that the team would sit well under .500 and 7.5 games out of playoff position at the end of July. Such as it is, the Orioles spent this year’s trade deadline turning over roughly a third of their roster. Over the last week or so, the O’s have traded relievers Gregory Soto, Seranthony Domínguez, and Andrew Kittredge, along with infielders Ryan O’Hearn and Ramón Urías. Then on Thursday afternoon, Anthony DiComo reported that Cedric Mullins was on his way to the Mets; a few hours later, Jeff Passan broke the news that Charlie Morton would be joining the Tigers. The only healthy pending free agent who wasn’t traded out of Baltimore is Tomoyuki Sugano, and with Zach Eflin hitting the IL mere hours before the deadline, Sugano is now a load-bearing member of the rotation.

The Cubs sit just one game back of the Brewers in the NL Central, but the two division rivals exist as almost perfect inverses of one another when it comes to on-field performance. Chicago ranks second in wRC+ at 117 and 15th in ERA- at 98, while Milwaukee ranks 13th in wRC+ at 102 and fifth in ERA- at 89. Their common ground is on defense, where both teams are top three in defensive value.

Coming off a series loss against the Brewers and with the trade deadline bearing down, the Cubs added some depth to their weaker side of the ball on Wednesday by acquiring pitcher Michael Soroka from the Nationals. Soroka will be a free agent at the end of this year, after signing a one-year $9 million dollar deal with the Nats last December. In return, Washington received Triple-A outfielder Christian Franklin, Chicago’s fourth-round pick in 2021, and 18 year-old shortstop Ronny Cruz, whom the Cubs selected in the third round of the 2024 draft.

Every time I hear the name Robbie Ray, I think about the bar scene from 2002’s Sweet Home Alabama, where Reese Witherspoon’s character Melanie drunkenly stumbles up to an old friend as he’s about to attempt a pool shot. Through a fit of giggles she says, “Bobby Ray! Don’t blow this one, OK?”

Most recently, this happened when I read that Robbie Ray had been named to the National League All-Star team. Because Robbie Ray has not been blowing it this season. In fact, he’s been posting numbers not far off the pace from his 2021 Cy Young season. But despite the Cy Young on his résumé, I probably think about Bobby Ray more often than Robbie Ray, because Robbie followed up his award-winning performance with a merely average 2022, and then spent much of 2023 and 2024 on the IL. Overall, Ray’s career has been a bit of an up-and-down journey, and if we’re comparing career arcs to character arcs, Ray’s is more akin to Melanie’s than Bobby Ray’s, despite the similar name.

Dropping in on Ray’s 2021 season is roughly equivalent to where we drop in on Melanie Carmichael at the beginning of Sweet Home Alabama. Melanie (whose real last name is Smooter, but she chose to adopt a more sophisticated persona after leaving Alabama for the big city) is a fashion designer fresh off a successful debut at New York Fashion Week and newly engaged to the mayor’s son (Patrick Dempsey). Melanie has accumulated career accolades and social status, just as Ray spent his 2021 season reeling in award votes and leveling up his status as a starting pitcher. Read the rest of this entry »

Last week, I began a series of pieces about team win-loss totals as estimated by BaseRuns, first by taking a broad look at the methodology and its limitations, then by zooming in on the offenses that deviate most notably from their BaseRuns assessment in the run scoring department. Let’s wrap up with a look at the defenses that sit furthest from their runs allowed approximation.

In the offense edition, I used a game show format to evaluate whether the perspective offered by BaseRuns has a point, or if there’s something its methodology is overlooking. We’ll keep that framework going for the defenses as well. Here’s a reminder of how it works:

To determine whether or not BaseRuns knows what it’s talking about with respect to each team, imagine yourself sitting in the audience on a game show set. The person on your left is dressed as Little Bo Peep, while the person on your right has gone to great lengths to look like Beetlejuice. That or Michael Keaton is really hard up for money. On stage there are a series of doors, each labeled with a team name. Behind each door is a flashing neon sign that reads either “Skill Issue!” or “Built Different!” Both can be either complimentary or derogatory depending on whether BaseRuns is more or less optimistic about a team relative to its actual record. For teams that BaseRuns suggests are better than the numbers indicate, the skill issue identified is a good thing — a latent ability not yet apparent in the on-field results. But if BaseRuns thinks a team is worse than the numbers currently imply, then skill issue is used more colloquially to suggest a lack thereof. The teams that are built different buck the norms laid out by BaseRuns and find a way that BaseRuns doesn’t consider to either excel or struggle.

In a post yesterday, I wrote about the BaseRuns approach to estimating team winning percentages and how it attempts to strip away context that doesn’t pertain to a team’s actual ability, so as to reveal what would have happened if baseball were played in a world not governed by the whims of seemingly random variation. In this world, a win-loss record truly represents how good a team actually is. Try as it might, the BaseRuns methodology fails to actually create such a world, sometimes stripping away too much context, ignoring factors that do speak to a team’s quality, or both.

I delayed for a separate post (this one!) a deeper discussion of specific offensive and defensive units that BaseRuns represents quite differently compared to the actual numbers posted by these teams. To determine whether or not BaseRuns knows what it’s talking about with respect to each team, imagine yourself sitting in the audience on a game show set.
