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.

Love ’em or hate ’em, the class of “expected” stats has utility when we’re talking about predicting the future. The data certainly inspire mixed feelings among fans, but they perform an important task of linking the things that Statcast and similar non-traditional metrics say to performance on the field. A hard-hit rate of X% or a launch angle of Y degrees doesn’t really mean anything by itself, without the context of what’s happens in baseball games.

I’ve been doing projections now for nearly half (!) my life, so outside of my normal curiosity, I have a vested interest in using this kind of information productively in projections. Like the Statcast estimates (preceded with an “x,” as in xBA, xSLG, etc.), ZiPS has its own version, very creatively using a “z” instead.

It’s important to remember these aren’t predictions in themselves. ZiPS certainly doesn’t just look at a pitcher’s zSO from the last year and say, “Cool, brah, we’ll just go with that.” But the data contextualize how events come to pass, and are more stable than the actual stats are for individual players. That allows the model to shade the projections in one direction or the other. Sometimes that’s extremely important, as in the case of home runs allowed for pitchers. Of the fielding-neutral stats, home runs are easily the most volatile, and home run estimators for pitchers are much more predictive of future home runs allowed than are actual home runs allowed are. Also, the longer a pitcher “underachieves” or “overachieves” in a specific stat, the more ZiPS believes in the actual performance rather than the expected one. More information on accuracy and construction can be found here. Read the rest of this entry »

With the caveat that his last outing was his worst of the 2025 campaign — seven earned runs over three innings against the Syracuse Mets — Cade Cavalli appears ready to return to the big leagues. Once he does, Washington Nationals fans will see a somewhat different pitcher than the one who made his last (and only) appearance in the majors on August 28, 2022. Going under the knife has a lot to do with that. After initially landing on the shelf with shoulder inflammation, Cavalli blew out and had Tommy John surgery in March 2023. At the time, the right-hander was his team’s top prospect and no. 63 on our Top 100 as a 50 FV. (Cavalli will be assigned a 45 FV on our forthcoming Nationals list.)

His return to full health was both long and arduous. After missing all of 2023, Cavalli made just a smattering of appearances a year ago, none above High-A, and he went through a dead arm phase this spring and didn’t take the mound until mid-April. Since then, he has been solid more often than not. While his ERA over 10 starts with Triple-A Rochester is 5.27, the now-26-year-old has gone five or more innings while allowing two or fewer runs on four occasions.

When we got reacquainted last month — I first interviewed him in July of 2021 when he was in Double-A — Cavalli explained how he has deviated from his pre-surgery days. Read the rest of this entry »

Coming into 2025, you might not have expected Alejandro Kirk and Ernie Clement to play central roles on a playoff contender. Neither player was an above-average hitter last season; in fact, each hit for a 93 wRC+ while playing regularly for a team that won just 74 games. Yet the pair rank first and second in position player WAR on the Blue Jays, thanks not only to improved offense but exceptional glovework, with Kirk battling the Giants’ Patrick Bailey for the top spot in two catching metrics, and Clement ranking among the best third basemen while also posting strong metrics in limited duty at the three other infield positions. The pair have not only helped the Blue Jays to a 47-38 record and the top AL Wild Card position, but also the top ranking in my annual midseason defensive breakdown.

Kirk and Clement aren’t Toronto’s only defensive stalwarts. Second baseman Andrés Giménez and center fielder Myles Straw, a pair of light-hitting glove whizzes acquired from the Guardians in separate trades this past winter, have been strong at their respective positions, with the latter helping to cover for the absences of Daulton Varsho. A Gold Glove winner last year, Varsho missed the first month of this season recovering from right rotator cuff surgery, and returned to the injured list on June 1 due to a strained left hamstring. Even in limited duty, Straw, Varsho, and Giménez — who missed about four weeks due to a quad strain, with Clement filling in at second for most of that time — have all rated as three to five runs above average according to Statcast’s Fielding Runs Value (FRV), and five to eight above average according to Defensive Runs Saved (DRS). Clement has totaled 12 DRS and 10 FRV at the four infield spots; in 359.2 innings at third, he’s second in the majors in both DRS (7) and FRV (5).

This is the third year in a row I’ve taken a midseason dip into the alphabet soup of defensive metrics, including Defensive Runs Saved (DRS), Statcast’s Fielding Run Value (FRV), and our own catcher framing metric (hereafter abbreviated as FRM, as it is on our stat pages). One longtime standby, Ultimate Zone Rating (UZR), has been retired, which required me to adjust my methodology. Read the rest of this entry »

Junior Caminero has, as of this writing, grounded into 22 double plays in 333 plate appearances this year. The first year both the AL and NL counted double plays was 1939; since then, there have been some 9,295 individual player seasons of 300 or more plate appearances. Caminero’s current campaign is already in the top 300 in double plays.

Two months ago, Leo Morgenstern wrote an article titled “Carlos Correa Is Keeping the GIDP Alive,” which conceded, right in the lede, that even though Correa had grounded into an appalling six double plays in April alone, Caminero was leading the league. The Rays third baseman has only expanded that gap; Jacob Wilson is second with 15 double plays. Read the rest of this entry »

On Sunday, the Angels made 22-year-old James Wood the first player to receive four intentional walks in a single game since Barry Bonds in 2004. You could argue the plan worked, too, as Wood came up with at least one runner in scoring position all four times, and the only one of those runners to score did so on a bizarre, inning-ending double play. If the Angels’ goal was to avoid the big inning, then they nailed it. If their goal was to win the game, well, hope springs eternal; the Nationals won, 7-4, in 11 innings. The obvious takeaway is the 6’7” Wood is a terrifying talent, but just as obvious is how out of step with current baseball thinking – or really any baseball thinking – this move was.

Wood is having an incredible season, launching 22 home runs, walking 14.5% of the time, and batting .283. His 156 wRC+ makes him the eighth-best hitter in the game this season and a genuine contender for the National League MVP. However, it’s impossible to argue that he’s in Bonds territory. Bonds earned four IBBs four different times that year. He was in the midst of his fifth straight 45-homer season and 13th straight 30-homer campaign. He held the single-season home run record and was closing in on the all-time one. He put up a 233 wRC+ en route to an absurd 11.9 WAR in 2004. He was in his own league. Moreover, the game has progressed in its thinking since 2004, and it’s now widely understood that an intentional walk is rarely the smart move.

Stathead, which uses Retrosheet data from back before intentional walks were an official stat, lists 12 instances in which a player received at least four intentional walks in a game. This John Schwartz article from the 1980 Baseball Research Journal can teach you even more about the earlier history of the IBB, including the contention that Mel Ott received five intentional passes during the second game of a doubleheader on October 5, 1929 (though Retrosheet only lists three of Ott’s five walks that day as intentional). So this is an extraordinarily rare feat, and fully a third of the times it has happened in baseball history, it was specifically happening to Bonds in 2004. Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the St. Louis Cardinals. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the fifth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Jay Jaffe: Good afternoon, folk! Greetings from Wellfleet, where I’m on my annual family (semi) vacation

12:02

Jay Jaffe: This is my working week up here, which kicked off with my tribute to the late Dave Parker, who sadly passed away less than a month before his Hall of Fame induction https://blogs.fangraphs.com/remembering-the-cobra-dave-parker-1951-202…

12:04

Jay Jaffe: I don’t think you have to be a strong proponent of Parker’s HOF case to feel the sadness that comes with the timing of his death. I’m glad he experienced the outpouring of joy, appreciation and love that came with the news of his election.

12:04

Jay Jaffe: I’m working on my annual midseason look at the best team defenses, and will have something on Clayton Kershaw’s run for 3,000 strikeouts later this week as well.

12:05

Jay Jaffe: Planning to take in a Cape Cod League game sometime after the 4th

Jay Jaffe: anyway, on with the show
