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.

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 »

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.

When Ozzie Albies signed his current contract, I decried it in such terms that, well, “decried” was an accurate description. This 22-year-old middle infielder, coming off a season of 24 home runs and 4.0 WAR, had signed away his prime earning years to the Braves for seven years at an average of $5 million per. Two option years could keep him in Atlanta through 2027 without increasing the contract’s AAV. It was an all-time swindle, I wrote. Esau got a better deal when he sold his inheritance for a bowl of stew.

Six years later, I sit here contemplating a question that once would’ve seemed unfathomable: Should the Braves pick up those option years?

Through his first 83 games, Albies is hitting .223/.297/.321, which is a wRC+ of 74. He has never before hit under .259, nor slugged under .450, nor posted a wRC+ under 100 in any previous healthy season. There’s probably a little bad batted ball luck in there, and some malaise from Atlanta’s comprehensively frustrating, injury-riddled season to date. Read the rest of this entry »

Last December, 33 years after he last played, Dave Parker was finally elected to the National Baseball Hall of Fame. The lefty-swinging, righty-throwing “Cobra” had once been regarded as the game’s best all-around player, a 6-foot-5, 230-pound slugger who could hit for power and average, had plenty of speed as well as a strong and accurate throwing arm, and exuded as much charisma and swagger as any player of his era. But injuries, cocaine use, and poor conditioning curtailed his prime, and while he rebounded to complete a lengthy and successful career, in 15 years on the writers’ ballots, he’d never drawn even one-third of the support needed for election. He hadn’t come close in three tries on Era Committee ballots, either, but buoyed by the positive attention he had generated while waging a very public battle with Parkinson’s Disease, and backed by a favorable mix of familiar faces on the Contemporary Baseball Era Committee, he finally gained entry to the Hall, alongside the late Dick Allen.

Unfortunately, Parker did not live to deliver the speech he said he’d been holding for 15 years. Just shy of one month from the day he was to be inducted into the Hall of Fame, he passed away at age 74 due to complications from Parkinson’s Disease, which he was diagnosed with in 2012.

Parker is the third Hall of Famer to die between election and induction. Eppa Rixey, a lefty who pitched in the National League from 1912 to ’33, was elected by the Veterans Committee on January 27, 1963. He died one month and one day later, at the age of 71. Leon Day, a righty who starred in the Negro Leagues from 1934 to ’46, and later played in Mexico and in the affiliated minor leagues, was elected by the Veterans Committee on March 7, 1995. He died six days later, at the age of 78. Read the rest of this entry »

Cam Schlittler has emerged as the top pitching prospect in the New York Yankees organization. His ability to overpower hitters is a big reason why. In four starts since being promoted to Triple-A Scranton/Wilkes-Barre on June 3, the 6-foot-6, 225-pound right-hander has logged a 1.69 ERA and a 40.2% strikeout rate over 21-and-a-third innings. Counting his 53 frames at Double-A Somerset, Schlittler has a 2.18 ERA and a 33.0% strikeout rate on the season.

The 2022 seventh-rounder out of Northeastern University is averaging 96.5 mph with his heater, but more than velocity plays into the offering’s effectiveness. As Eric Longenhagen wrote back in January, Schlittler’s “size and arm angle create downhill plane on his mid-90s fastball akin to a runaway truck ramp, while the backspinning nature of the pitch also creates riding life.”

I asked the 24-year-old Walpole, Massachusetts native about the characteristics our lead prospect analyst described in his report.

“Arm slot-wise it’s nothing crazy,” Schlittler said in our spring training conversation. “I’m more of a high-three-quarters kind of guy, but what I didn’t realize until looking at video a couple months ago is that I have really quick arm speed. My mechanics are kind of slow, and then my arm path is really fast, so the ball kind of shoots out a little bit. With my height, release point— I get good extension — and how fast my arm is moving, the ball gets on guys quicker than they might expect.” Read the rest of this entry »

On Wednesday afternoon, Paul Skenes and Jacob Misiorowski met in one of the most exciting pitching matchups of the season so far. Skenes is the best pitcher in baseball, while Misiorowski is the hardest-throwing starter. It was must-see TV. Michael Baumann covered the event in the most Baumann way possible, focusing on its hugeness — literally. “As impressed as I was with this display of firepower, awe at the future of pitching was not my primary takeaway. No, watching Skenes and Misiorowski do battle made me feel uneasy,” Baumann wrote. “See, these guys are huge.” He followed those words up with one of my favorite paragraphs in the illustrious annals of baseball writing:

This is too big. Both of them. The modern baseball field was designed for Scots-Irish immigrants with bad childhood nutrition and kidney disease. When 5-foot-11 Honus Wagner was the biggest, strongest player in the league. If you told the founding fathers of baseball that one day ballplayers would get so big they couldn’t borrow pants from Dave Bautista… well first of all, I guess you’d have to explain Dave Bautista to Abner Doubleday and Alexander Cartwright. You get my point.

I’m not going to write about the Skenes-Misiorowski matchup. What more could I possibly add? Instead, I will begin this week’s mailbag by answering a question about Misiorowski’s earth-shattering velocity. Before I do, though, I’d like to remind all of you that while anyone can submit a question, this mailbag is exclusive to FanGraphs Members.
