Bryan Balzer is arguably the most intriguing prospect in the San Diego Padres system. Currently ranked eighth with a 40 FV, the 21-year-old right-hander had virtually no pitching experience when he entered pro ball in 2023. Moreover, he blew out his elbow and had Tommy John surgery following his lone turn on the mound. That was at Joso Gakuin High School, roughly an hour northeast of Tokyo.

His current season has been somewhat of a mixed bag. Between Low-A Lake Elsinore (60 1/3 innings) and High-A Fort Wayne (32), he has a record of 6-2 to go with a 4.58 ERA, a 5.17 FIP, and a 23.4% strikeout rate. But while at times he’s been all too hittable, he has also shown flashes of high-ceiling potential. When I saw him toe the rubber for Fort Wayne in mid-July, Balzer fanned eight batters — including Tigers top prospect Bryce Rainer with two out and the bases juiced — while holding West Michigan to one run over five frames. A day prior, I asked him about his decision to sign with the Padres rather than joining another MLB organization or staying home to pitch in NPB.

“My goal was to be a professional baseball player; I didn’t care if was Japan or America,” replied the Yokosuka native. “But I grew up watching Yu Darvish and wanted to be on his team.”

Balzer, who was mostly raised in Nippon but spent a few years stateside while in grade school, went on to say that his decision was also influenced by his Tommy John surgery; the Padres expressed less concerned than other MLB teams about his having gone under the knife. As for the NPB teams he might have landed with — this via the league’s draft process — the Hanshin Tigers were the first to have a scout approach him after his lone pitching appearance. In terms of overall interest, he recalls the Tokyo Yomiuri Giants having been “the main ones.” Read the rest of this entry »

Sunday afternoon, the Astros gave up seven unanswered runs to lose to the A’s 7-6. That loss, against the team with the worst record in the American League, dropped Houston below .500 for the first time this month, and into a tie with the Texas Rangers for the AL West division lead. That was the last game of a 3-9 homestand. The capper to this bummer of a fortnight in Houston followed promptly; the team and GM Dana Brown mutually agreed to part ways Sunday evening, which is team-and-manager speak for firing him.

Boy, am I bummed that I’ve already made an Apollo 13 reference about the Astros this year. Two in the same season would just be too many. So allow me to use some Shakespeare instead: Something is rotten in the state of Texas. While a 12-game stretch of poor play is a strange reason to change GMs, this move wasn’t about a couple of poor weeks of play. Instead, it’s about the last couple of years of poor play; the once-dominant Astros missed the playoffs in 2025, and this year they’re on track for their worst record since 2014 (excluding the pandemic-shortened 2020 season, when they went 29-31 but still made the playoffs). The farm system is one of the worst in baseball – 29th in our farm system rankings. The big league team has been outscored by 44 runs this year, and BaseRuns suggests Houston has played even a bit worse than that. Things really have deteriorated in Space City.

What’s meaningfully less clear is how much of that blame should be apportioned to Brown. He joined the Astros immediately after their 2022 World Series victory, replacing the departing James Click. Not many incoming GMs inherit a roster that just won the whole ball of yarn, but that cuts both ways. Brown inherited a great roster as well as the kind of dysfunction that leads a team and its GM to split up while simultaneously reaching the peak of the sport. Read the rest of this entry »

The Phillies won their ninth straight game on Sunday. Cristopher Sánchez started and Kyle Schwarber hit a game-winning home run.

There are home runs and then there are home runs, and even by Schwarber’s standards, this one was a tank: straight out to dead center, over the batter’s eye. Read the rest of this entry »

It was a wild week across baseball, with walk-offs, blowouts, and a playoff picture in the American League that’s still incredibly crowded. With one week left in August, there’s not much time left for those teams on the fringe of the AL Wild Card race to make a move.

Our power rankings use a modified Elo rating system. If you’re familiar with chess rankings, you’ll know that Elo is an elegant ranking format 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%). The weighted Elo ranks are then displayed as “Power Score” in the tables below. As the best and worst teams sort themselves out between now and October, they’ll filter to the top and bottom of the rankings, while the exercise remains reactive to hot streaks and cold snaps. If you’re looking for a visual representation of the ups and downs of your team throughout the season, look no further than the brand new Power Rankings Board in the FanGraphs Lab.

First up are the full rankings, presented in a sortable table. Below that, I’ve grouped the teams into tiers with comments on a handful of clubs. You’ll notice that the official ordinal rankings don’t always match the tiers — there are times where I take editorial liberties when grouping teams together — but generally, the ordering is consistent. One thing to note: The playoff odds listed in the tables below are our standard Depth Charts odds, not the coin flip odds that are used in the ranking formula. Read the rest of this entry »

Last year, though he missed the first two and a half months of this season due to bilateral epicondylitis, Giancarlo Stanton bashed 24 homers in 77 games while hitting for a 158 wRC+ and 1.8 bWAR. Despite its half-season nature, the campaign was his strongest since 2021, and it appeared as though he had enough momentum to reach 500 home runs and, quite likely, secure a spot in the Hall of Fame. Unfortunately, Stanton has once again been unable to stay on the field. After straining his right calf in late April and then reinjuring it while rehabbing in mid-June, he suffered a moderate-grade left calf strain last week, one that may very well prevent him from playing again this season.

Manager Aaron Boone said on Saturday that Stanton strained his left calf while running the bases earlier in the week. He didn’t offer a timetable for the slugger’s return, but conceded, “We’re at a point in the calendar where it gets challenging… You all know how bad he wants to be on that field and contributing to a championship… Hopefully we just continue working to get him right and healthy.”

The 36-year-old Stanton has played in just 24 games this season, batting .256/.302/.422 (103 wRC+) with just three homers in 96 plate appearances. Those three homers boosted his career total to 456, the most of any active player, but they’ve run critical time off of his clock, so to speak. By colleague Dan Szymborski’s ZiPS-driven estimate, Stanton had a 71% chance of reaching 500 homers coming into the season, but per Dan’s hot-off-the-presses estimate, those odds are down to 51%, and to these eyes that still feels high. Stanton’s MVP award, two home run titles, five All-Star appearances, postseason performance (.254/.322/.605 with 18 homers) and otherworldly Statcast numbers might be enough to overcome a slight shortage in JAWS, but with just 47.0 career WAR (the Baseball Reference version, which is true for all of the figures cited here unless otherwise indicated), 35.4 peak WAR, and 41.2 JAWS, he’s just 37th among right fielders, 14.8 points below the standard. I don’t think that’s going to cut it. Read the rest of this entry »

The hottest pitching prospect in baseball joined the coldest pitching staff in baseball over the weekend.

Mariners left-hander Kade Anderson was solid in his major league debut on Saturday. The Cubs weren’t the softest landing, entering the day as the best lineup in the majors with a 111 wRC+. But the top prospect kept the Chicago batters off balance for five innings, striking out five with minimal resistance. Manager Dan Wilson left Anderson in to face the top of the order for a third time to begin the sixth — a controversial decision, but perhaps a necessary one given Seattle’s pitching implosion over the last two months — and he was quickly slugged out of the game. It was a sour note to end an otherwise strong debut, although dogpiling with his new teammates following a walk-off home run by Randy Arozarena certainly improved the mood.

The Mariners took Anderson third overall out of LSU last year. He got his first taste of pro ball this spring and blew through the competition in Double-A, posting a 1.06 ERA, a 1.78 FIP, a 40.5% strikeout rate, and a 3.9% walk rate over 93 1/3 innings. He made it as high as third overall on our Top 100 Prospects list, definitively the best pitching prospect in baseball at the time of his debut. He might have been called up sooner, but, well, I’ll get to Seattle’s pitching mess soon enough. Read the rest of this entry »

Jacob deGrom tallied his 2,000th strikeout last week, providing another late-career achievement that might be engraved on a Cooperstown plaque sometime in the 2030s. That deGrom would reach 2,000 strikeouts seemed almost certain back at the end of the 2020 season, when he was 641 away. At that time, he’d struck out at least 200 batters in four of his six non-pandemic seasons. The first of those two other seasons was his 2014 NL Rookie of the Year campaign, when he didn’t debut until May 15, and in 2016, injuries limited him to just 24 starts. But since 2020, deGrom has been an example of Zeno’s paradox, seeming perpetually stuck in medias res. Achilles did eventually catch the tortoise, and deGrom and calculus won the day.

deGrom’s journey to 2,000 is a good reminder of why I like to occasionally harass ZiPS for milestone probabilities rather than simply dividing a player’s remaining distance by his most recent seasonal number and calling it a day. Whether or not there are infinite universes where every possibility happens, in this one, tendons tear and players age. A player can be on pace to finish with 500 home runs for a decade and never come particularly close, while another can sneak in the back door to a milestone that nobody saw coming, as Nick Markakis threatened to do late in his career.

The uncertainty is what makes baseball (and life) interesting. I can tell you that Aaron Judge needs 115 homers to make it to number 500; I have a calculator for that, and even if I didn’t, I was once a third-grader. But the road is hard to map, and the aging curve, performance models, and injury models in ZiPS give us a better idea as to the probability that Judge will hit 500 or 600 in this particular universe. It’s no fun to have such a tool and not deploy it, so it’s a good time to do an update on baseball’s search for pretty, round numbers. Read the rest of this entry »

Jonah Cox had never set foot in Wrigley Field prior to June 5th of this season. It turned out to be a day he won’t soon forget. Six games into his MLB career, the 25-year-old San Francisco Giants outfielder went 3-for-3 and left the yard for the first time at baseball’s highest level. In front of an announced crowd of 39,060, the visitors ran roughshod over the Chicago Cubs by a count of 18-3.

His initial impression of the Friendly Confines?

“It’s one of those stadiums you see in movies, like Rookie of the Year, so when you walk out there it’s like ‘Oh my gosh,’” the Colorado native told me earlier this week. “Knowing the history and the fanbase, it’s just a really cool place to play.”

“Oh man, the ball was flying,” Cox went on to say of the contest, which featured eight home runs, seven of them by the Giants, “It was a ton of fun watching guys swing and have so much success. Then I got the call to come in and face Hoby Milner, the lefty [in the sixth inning with the Giants leading 9-0]. I was excited to get in there, and one thing led to another.”

Did it ever. The rookie recorded his second hit of the game — and just his third in the majors — in that same inning, which ended with the Giants on top 16-0. Then came the top of the ninth. With Cubs catcher Carson Kelly toeing the rubber, Cox cleared the ivy. Read the rest of this entry »

As you all probably know, at the start of every season, the FanGraphs staff puts together our bold predictions for the coming year. Each is, to varying degrees, plausible but unlikely, which is what makes it such a fun exercise. Anyway, entering the 2025 season, my bold prediction was: Corbin Carroll will become the fifth-ever 20/20/20/20 player — 20 doubles, 20 triples, 20 home runs, and 20 stolen bases in a single season — joining Frank Schulte in 1911, Willie Mays in 1957, and Curtis Granderson and Jimmy Rollins, who both did it in 2007. Carroll ultimately fell just three triples short of the threshold, while tallying 32 doubles, 31 homers, and 32 steals.

I decided not to run it back this year, figuring that wouldn’t be as fun, though I am very much still rooting for it to happen. The 20/20/20/20 Club is one of the most exclusive baseball has to offer. Pulling it off requires a precise combination of power, speed and instincts, and it has to happen at the exact right moment in a player’s career. As I wrote in my bold prediction: “A player needs to have enough pop to hit 20 homers, but not so much that the majority of his extra-base hits land in the seats. He also needs the speed to steal bases and stretch singles into doubles and doubles into triples. His instincts must be sharp, so he can know when to attempt the extra base without running into outs.”

Last Saturday, when I saw that Carroll had doubled and tripled in a 10-3 Diamondbacks win over the Braves, I pulled up his player page to check on his progress. He was up to 26 doubles, 15 triples, 18 homers, and 16 steals. He stole a base the next day, and after going without an extra-base hit in Arizona’s three-game series against the Red Sox, Carroll entered play Friday at 26 doubles, 15 triples, 18 homers, and 17 steals with 34 games left to play. This prompted my own question for this week’s mailbag, which I will get to momentarily. We’ll also answer your questions on the worst player to ever hit three home runs in a game, the biggest drop-off for a player in the season after finishing second in the MVP voting, and teams missing the playoffs despite leading the league in run differential.
