The A’s have been a bummer of a team to follow for a few years now. They’re moving to Vegas. The fans are protesting, but probably fighting a losing battle. They’re going to play in Sacramento, in withering heat, at a (really nice!) minor league stadium. The owner’s a walking punchline. They lost 112 games last year and then made almost no moves over the winter.

Something’s been brewing in the East Bay, though. Not in terms of a surprise playoff contender – they’re 47-68 on the year, and their playoff odds hit 0.0% on June 10. But nonetheless, this is a much better team than last year’s edition, and it’s mostly happened thanks to internal improvements. This version of the A’s looks downright frisky. Last year, playing them was basically a bye series; this year, they’ve almost matched their win total from ’23 and we’re in early August. How’d they do it? In one word, variance. In many words, well, read on and find out.

This probably isn’t a problem for most people, but I’m plagued constantly by the memory of frustrating baseball arguments from days past. I probably get into these arguments more than most people, partially because of my (and I hope it doesn’t sound immodest to say this) vast knowledge of the sport, but mostly because I’ve lived most of my life in New Jersey, which his home to the most stubborn, tendentious people you’d ever have the misfortune of meeting.

One such argument took place probably close to 15 years ago, when I ruined what was supposed to be a relaxing Friday evening down the shore by getting into a shouting match over the issue of Alex Rodriguez vs. Derek Jeter. I preferred A-Rod, who would go on to finish his career with a slugging percentage more than 100 points higher than that of his Yankees teammate. I was arguing against someone whose case rested on Jeter being “more clutch.”

If you’re old enough to remember what “analytics bloggers” like me thought about that argument in the 2010s, you can understand my quickness to anger and probably imagine the colors my face turned. When the dust settled, Jeter — who, it turns out, was actually an exceptional hitter all along — did finish with a better career postseason wRC+ than A-Rod. But it was close: 121 to Jeter, 116 for Rodriguez. Read the rest of this entry »

With Spencer Strider and Ronald Acuña Jr. both out for the season, the Braves haven’t been anywhere close to full strength for awhile, and the injury bug has continued to bite, with Michael Harris II and Ozzie Albies sidelined for extended periods as well. In a dispiriting sequence involving the rotation, Max Fried returned from the injured list on Sunday (and was roughed up), then Reynaldo López landed on the IL. With so many absences, the cracks are beginning to show. Where the Braves occupied the top National League Wild Card spot for a good long time, they entered Tuesday having fallen into a three-way tie with the Diamondbacks and Padres.

The not-so-well-kept secret about the Braves is that since finishing April with a 19-9 record, they’ve gone just 41-42, and haven’t been more than a game over .500 in any calendar month. They went 13-14 in May, 14-13 in June, and 12-13 in July; so far, they’re 2-2 in August. Here’s how they now sit via the standings and our Playoff Odds:

The 2024 season started absolutely terribly for the White Sox. After 25 games, the team’s record stood at 3-22, thanks in large part to an anemic offense that barely scored two runs per game. At the time – the Sox were 3-21 when I wrote the piece – I posed the question of whether the White Sox had a real shot at losing 120 games. I concluded that it was possible, with ZiPS projecting an 8.1% chance that Chicago would lose 120 games, better odds than even the Oakland A’s during their brutal 2023 season. That appeared to be the end of the story, at least until July.

After the awful start, things got slightly sunnier for the Sox for awhile. They swept the Tampa Bay Rays, a team expected to be a contender, and over the next not-so-nice 69 games, they went 24-45. While a .348 winning percentage isn’t in the same zip code as competence, that’s a 56-win pace, a level of lousiness that is fairly commonplace for the worst teams in the league, not the stuff of legend. But as the trade deadline approached, things again turned grim.

The White Sox won the first game of a doubleheader against the Twins on July 10, improving their record to 27-67. That date, almost a month ago, was the last time the White Sox won a game. The team’s 21 straight losses ties them with the 1988 Orioles for the second-most consecutive losses in modern baseball history (since 1901), just two losses behind the biggest loser, the 1961 Philadelphia Phillies. In some sense, the current one might be the most impressive losing streak, simply because the differences between the best and worst teams in baseball has shrunk over the years, making streaks like this more challenging to achieve.

And no, the White Sox haven’t been unlucky. Using a modified Pythagorean winning percentage (I use 1.83 for the exponent rather than two, as it’s been slightly more accurate historically), the White Sox have been the fourth-worst team since 1901.

If the season ended today, the White Sox would have the worst modified Pythagorean win percentage in more than 80 years, since the Philadelphia Phils in 1942. No, that’s not a typo; the Phillies officially shortened their team name for a season in 1942, apparently because they decided they didn’t want to have the same name as the line of cigars.

Problem is, the season doesn’t end today, so the Sox haven’t closed the deal yet. Regression toward the mean is a real thing, and one of the primary reasons why people overrate teams when things are going very well, and vice-versa. At the end of the day, a .235 winning percentage or the .272 in modified Pythag are likely – though not guaranteed – to go up over the remaining games. Projections represent a more stable description of a team’s ability, as well as one that’s generally more predictive of the future, and even with the diminished post-deadline roster, ZiPS sees the White Sox as “only” a .355 team, a 58-104 pace that represents merely a ho-hum level of awfulness.

But it’s also likely that given more games, these other terrible teams likely would have played better ball as well, for similar reasons. (Remember, Major League Baseball didn’t implement the current 162-game schedule until 1961.) While ZiPS projections date back to 2005, I have a quick little estimator for a team’s underlying ability that correlates fairly well with projections; it’s a mix of actual record, a team’s “wRC Pythagorean” — which uses wRC rather than runs score and allowed — and a model of regression toward .500. So I calculated the worst teams by this method and compared them to Chicago’s .356 estimate.

Whew, the White Sox once again fall to satisfyingly hurlicious levels as the worst team since the 1952 Pirates. And the thing is that for the Sox, a .355 record is lousy enough that they stand an excellent chance at losing 120 games anyway with the number of losses they already have banked. With 47 games to play, a .355 record would net them only 16.7 wins, leaving them at just under a 44-118 record, tantalizingly close to the 1962 Mets standard. And since we know that projections aren’t perfect, or at least maybe reality isn’t, that gives the White Sox ample room to continue to underperform and take the grand prize. Luckily, ZiPS can take care of that estimate.

Even with things projected not to go quite as badly, ZiPS gives the White Sox a slightly better than one-in-three chance (34%) to lose 120 games. And it could get even worse, with a 1% projected shot of finishing with a 35-127 record (or worse). That is championship brutality right there. The amusing thing is that this probability could’ve been even higher, but the White Sox didn’t trade Garrett Crochet or Luis Robert Jr. at the deadline, leaving the team encumbered with an additional 2-3 wins. If I remove Crochet and Robert Jr. in favor of their likely sub-replacement replacements, ZiPS projects the Pale Hose to have a 66% chance of losing at least 120 games!

I’m not sure I’d go so far as to call it a silver lining, but hope remains even for the most woeful teams in baseball. The last team to make a serious late run at 120 losses, the 2003 Tigers, improved quickly in the following seasons and made it to the World Series just three years later. Those 1952 Pirates were in the middle of a full rebuild helmed by legendary general manager Branch Rickey, hired in ’51, and though health problems forced him to step down in ’55, the organization assembled many of the key players who were on the World Series-winning team in ’60. And let’s not forget that seven years after losing 120 games, the Mets won the 1969 World Series. White Sox owner Jerry Reinsdorf isn’t one to embrace change, but a disaster of epic proportions could, in theory, be the one thing that would prompt him to overhaul the organization. I wouldn’t say I’m terribly optimistic about this actually happening, but with an improved farm system – we now rank Chicago’s farm as the third best in baseball – and maybe a better front office assembled, the Sox could turn things around.

Whether the White Sox have a brighter future is something we’ll have to wait to find out. For now, enjoy these Sox as they reach new levels of ineptitude, because they may be the worst major league team you’ll ever see.

The smooth, lefty stroke has aged like fine wine through baseball history. Ben Rice is one of the latest examples of a left-handed hitter whose swing alone makes him fun to watch. Moving through the Yankees’ system as a bat-first catcher, Rice’s explosive minor league performance the last year forced his name into the big league conversation when first baseman Anthony Rizzo landed on the injured list with a fractured arm.

Even before Rizzo went down, Rice was mixing in more time at first base at Triple-A this season. That’s where the organizational need was, and his skills were not quite suited long-term at catcher anyway. As you’d expect, his defense at his new position has been a work in progress, and the same is true for the rest of his game. At the plate, Rice is experiencing the same ups and downs that most rookies do: Pitchers are figuring out how best to attack him, and he is learning how to make adjustments at the big league level.

With a 102 wRC+ over 142 plate appearances, Rice has been formidable thus far, but much of that is due to his hot streak that came along with his call-up. Across his first 19 games, he slashed .267/.348/.567 with five home runs, including the three against the Red Sox on July 6, and a 154 wRC+ over 69 plate appearances. During his 18 games (73 PA) since then, he’s batting .143/.247/.283 with two homers and a 53 wRC+. Despite that recent skid, ZiPS still believes in Rice, giving him a projected 110 wRC+ for the rest of the season. No projections come without uncertainty, of course, but there is a reason why ZiPS – and other projection systems – are confident the under-the-radar prospect can continue to be above average at the plate. Let’s get into it. Read the rest of this entry »

The Arizona Diamondbacks came through this weekend having won eight of their past 10 games, and after a bumpy start to the season, the Snakes are suddenly one of the most dangerous teams in the National League bracket. They hold a playoff spot even though their franchise player, Corbin Carroll, has hit like Eric Bruntlett this season, and despite having gotten nothing from the 2-3-4 slots in a rotation that was supposed to be a strength. Literally nothing in the case of Eduardo Rodriguez, who makes his season debut today.

So I was a little surprised when I went on Ketel Marte’s page and saw that we hadn’t written a standalone article about him on the main FanGraphs site this season. That’s our bad. Let me make up for it. Read the rest of this entry »

Last Friday, Davy Andrews put Aaron Judge into context. That’s fun for the usual reasons – “Wow, look how dominant Aaron Judge is!” never gets old. But his final conclusion – Judge hits like most batters do when opponents hang a bad slider middle-middle – got me thinking. We have a pitch-level model that estimates the worst pitches. Can we use it to get an idea of what it looks like to throw a pitch so bad it turns your opponents into Judge-esque offensive producers?

There’s an easy way to sort this out. When you look at a pitcher’s player page here at FanGraphs, you can see how we model each pitch. There are a ton of scores, but I’m going to be focusing on PitchingBot today, for reasons I’ll explain shortly. The player pages break each pitch down by command and stuff. In our internal database, it’s even better: You can look at any individual pitch and get a grade on it. I set out to find the worst pitches on the year to see whether they made hitters look invincible.

Ironically, the worst pitch thrown this year made the batter look extremely vincible. Here it is in all its glory:

On June 17, I wrote about the Mariners’ consistent success in overperforming their run differential and winning close games. The day after, they won their fourth game in a row, raising their record to 44-31 and their division win probability to 86.3%. Sitting 10 games above the second-place Astros, it seemed like a foregone conclusion that Seattle would claim the division crown. But six weeks later, the landscape looks far different. The Mariners blew that 10-game lead in just 24 games, the quickest that any team has ever surrendered such a large divisional lead, and the Astros even pulled ahead for a bit. The Mariners are now back in first, but just one game separates the two clubs.

The Mariners have gone 15-23 since their June 18 win that brought their division odds to an apex (12-23 if you take out a sweep of the White Sox, who are currently riding a 20-game losing streak). Some of this regression was to be expected – specifically, an offense that seemed to always find the timely hits stopped doing so. Seattle’s .388 BABIP in high-leverage situations fell to .225 over the past six weeks, and as small-sample good luck turned to small-sample bad luck, the team’s run scoring cratered. The Mariners have seen small improvements in low- and medium-leverage situations thanks to a recent offensive outburst — they’ve scored 6.3 runs per game over their nine games since they acquired outfielder Randy Arozarena — but it hasn’t been enough to fully right the ship. Their 94 wRC+ over their cold stretch and 95 wRC+ overall rank last among playoff hopefuls. Read the rest of this entry »

With the trade deadline behind us, we’ve entered the dog days of summer as the contending teams vie for position in the playoff races ahead of the September stretch run.

This season, we’ve revamped our power rankings. The old model wasn’t very reactive to the ups and downs of any given team’s performance throughout the season, and by September, it was giving far too much weight to a team’s full body of work without taking into account how the club had changed, improved, or declined since March. That’s why we’ve decided to build our power rankings model using a modified Elo rating system. If you’re familiar with chess rankings or FiveThirtyEight’s defunct sports section, you’ll know that Elo is an elegant solution that measures teams’ relative strength and is very reactive to recent performance.

To avoid overweighting recent results during the season, we weigh each team’s raw Elo rank using our coin flip playoff odds (specifically, we regress the playoff odds by 50% and weigh those against the raw Elo ranking, increasing in weight as the season progresses to a maximum of 25%). As the best and worst teams sort themselves out throughout the season, they’ll filter to the top and bottom of the rankings, while the exercise will remain reactive to hot streaks or cold snaps.

Mike Trout will not play baseball again this year. Last Thursday, Angels general manager Perry Minasian told reporters that the three-time MVP, who underwent surgery to repair the torn meniscus in his left knee on May 3 and who had recently begun a rehab assignment, had suffered another tear of the same meniscus. The 32-year-old slugger will need a second surgery, and once again, he’s finished for the season at far too early a point. Where we once anticipated speaking of Trout’s place in history alongside the likes of Willie Mays or Barry Bonds, his difficulties staying on the field during his 30s bring another superstar to mind: Ken Griffey Jr.

Trout played in just 29 games this season, the fewest in his career even including his 2011 cup of coffee. He was off to a flying start, albeit something of an uneven one, hitting 10 homers and stealing six bases. His home run total up to the point of his injury put him on a 55-homer pace, at the very least giving him a shot at topping his career high of 45 homers, set in 2019. Thanks to a more aggressive mindset, his stolen base total not only matched what he did from 2020–23 combined, it put him on pace for his first second 30/30 season; he hit 30 homers and stole 49 bases in his 2012 rookie season, then narrowly missed repeating in ’13 (27 HR, 33 SB) and ’16 (29 HR, 30 SB).

Despite those gaudy counting stats and the milestones they might portend, Trout was hitting an out-of-character .220/.325/.541, driven by an absurdly low .194 BABIP, 104 points lower than any of his seasons besides 2011, and 141 points lower than last year, when he played 82 games and totaled 362 plate appearances. His batting average and on-base percentage were respectively 43 and 42 points lower than the post-2011 career lows he set last year, but his .321 ISO was comparable to the marks he put up in 2017, ’18, and ’20 (he had 241 PA that year). Though he wasn’t hitting the ball as hard as usual, his .273 xBA and .599 xSLG suggest that he would have wound up in more familiar territory, slash line-wise. Read the rest of this entry »
