Kyle Stowers used to be part of that Baltimore Orioles position player prospect fire hose, but it’s OK if you forgot about him. Said fire hose has turned to a dribble as the Orioles’ fortunes have reversed. You also might have gotten him confused with Colton Cowser, which might be why the Orioles felt like they could trade him to Miami last summer for Trevor Rogers. (The other prospect in that trade, Connor Norby, has the same similar-name-mixup thing going with Coby Mayo. This town ain’t big enough for the two of us, etc.)

And if you still had your eye on Stowers after all that, you were probably put off when he hit .186/.262/.295 in 50 games for the Marlins after the trade. A better team, with a deeper talent pool, might’ve removed a 27-year-old outfielder with that batting line from its major league roster. But in Miami it’s more like a talent splash pad, so Stowers remains.

So much the better, because after 52 games, the former Stanford slugger is hitting .291/.362/.508. He has the same wRC+ as the much-celebrated Pete Crow-Armstrong, a higher wRC+ than Fernando Tatis Jr., Vladimir Guerrero Jr., and Bobby Witt Jr., three second-generation big leaguers with more than $1 billion in contracts among them.

As one-half of the majors’ most productive catching tandem, Carson Kelly doesn’t have enough plate appearances to qualify for the batting title, but like the Dodgers’ Will Smith, he’s been incredibly productive so far, particularly with runners in scoring position. Unlike Smith, he doesn’t have a lengthy track record of success; in parts of 10 major league seasons with five teams, Kelly has not only never made an All-Star team, he’s only played 100 games in a season twice, and finished with a 100 wRC+ or better just twice. But thanks to some changes to his swing mechanics over the past couple of seasons, he’s in the midst of a breakout campaign for the NL Central-leading Cubs.

The 30-year-old Kelly is hitting .290/.412/.589 with nine homers and a 179 wRC+ in 131 plate appearances. He’s started 28 of the Cubs’ 56 games behind the plate, while Miguel Amaya started 25 before landing on the injured list this past weekend due to an oblique strain, an injury that interrupted a promising start to the 26-year-old backstop’s season. Though Kelly homered after replacing Amaya in Saturday’s loss to the Reds, he was limited to a single late-inning cameo over the next three days due to an unspecified illness before returning to the lineup on Wednesday night. Instead of recalling 21-year-old prospect Moisés Ballesteros, who spent five games DHing for the Cubs earlier this month but whose defense needs more refinement, the Cubs brought up Reese McGuire from Triple-A Iowa to replace Amaya on the roster; he started all three games while Kelly was ailing, homering twice in his season debut against the Reds. All told, the trio of Cubs catchers has been great offensively:

No team has been caught stealing more than the Royals this year. As hard as it might be to believe, their 20 thwarted stolen base attempts are the most in the league. Their 70.1% stolen base success rate ranks 27th, as do their -2.1 weighted stolen base runs (wSB). This stands in stark contrast to what many think of as the Royals’ brand of baseball. After all, you’d have to go back to 2017 to find a full season in which the Royals didn’t rank among the top five AL teams in wSB, and all the way back to 2010 to find the last time their wSB was below league average. Thanks to players like Whit Merrifield, Jarrod Dyson, Adalberto Mondesi, Alcides Escobar and, most recently, Bobby Witt Jr., the Royals of the 2010s and 2020s developed a reputation as the most larcenous team in the league. From 2011-24, no team stole more bases, and no team racked up more wSB.

Kansas City’s stolen base supremacy hasn’t been limited to one side of the ball, either. From 2011-24, only two teams allowed fewer stolen bases than the Royals, and none caught would-be basestealers at a higher rate. According to the stolen base component of DRS (rSB), their catchers were twice as productive as any other team’s backstops in that period, while their pitchers were 12 runs better than the next-best team (the Diamondbacks) and more than three times as valuable as the next-best AL club (the Orioles). The Statcast numbers tell a similar story, although they only go back to 2016. From 2016-24, Kansas City catchers ranked second in both catcher and pitcher stealing runs. No other team placed within the top five in both metrics. So, you could make a pretty convincing case that preventing stolen bases is even more essential to the Royals’ brand of baseball than stealing bases, especially with the way things have gone in 2025. Their baserunners might be struggling to swipe bags like they did in the past, but their defense has taken control of the running game like never before. Read the rest of this entry »

You can’t keep Pete Crow-Armstrong away from the baseball field. I mean that in the sense that he’s a passionate young star who loves the game and plays with his hair on fire all the time. But I also mean that in a more literal sense. The Cubs might need to devise a system for keeping Crow-Armstrong away from the baseball field. He has a problem.

The Cubs walked off the Rockies on Monday night. The score was 3-3. With one out and two on in the bottom of the 11th inning, rookie Matt Shaw stayed back and punched a Tyler Kinley slider into right field, scoring Jon Berti from second base. It was thrilling. (For the Cubs, anyway; for the Rockies, it was probably akin to the feeling you have when you go to bed with a tickle in your throat and you just know that it’s a really bad cold coming on even though there’s no tangible basis for that certainty, and then you do in fact wake up in the middle of the night with a terrible cold.) As you’d expect after a thrilling(-slash-miserable) walk-off hit, Shaw got mobbed by his teammates.

Well, he got mobbed by one teammate, anyway. There’s Shaw, moments after his big hit, engaged in an intimate leaping chest bump with Crow-Armstrong. I mean “intimate” in the sense that it seemed like a special moment, but I also mean it in the sense that it’s just the two of them all alone on the grass under the romantic Chicago skies, smiling at each other like there’s nobody else in the whole wide world. The rest of the Cubs are just out of frame, celebrating too. Read the rest of this entry »

Count me among the multitudes who have been borderline obsessed with the emergence of Pete Crow-Armstrong as a superstar this season. I’m sure he’ll reach a saturation point eventually where hardcore fans get tired of him — it happened to superhero movies, and bacon, and Patrick Mahomes — but we’re not there yet.

Every time I write about PCA, I revisit the central thesis: This is a player who’s good enough to get by on his glove even if he doesn’t hit a lick. But out of nowhere, he’s turned into a legitimate offensive threat. Great athletes who play with a little flair, a little panache, a little pizzaz, tend to be popular in general. The elite defensive center fielder who finds a way to contribute offensively is probably my favorite position player archetype; the more I compared PCA to Lorenzo Cain, Jackie Bradley Jr., Enrique Bradfield Jr., Carlos Gómez… the more I understood why I’d come to like him so much.

In fact, let’s take a moment to talk about Gómez, and his offensive breakout in the early 2010s. Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the Kansas City Royals. 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.

Will Aaron Judge win the Triple Crown? If you were hanging around on FanGraphs three years ago, this question might sound familiar. If you don’t want to click the link, back at the end of 2022, both Judge and Paul Goldschmidt were within earshot of a Triple Crown in the final weeks of the season. The projected probabilities were firmly against either of them winning it (about 4% for Judge and 3% for Goldschmidt), the bank won as it tends to do, and Miguel Cabrera remained the only Triple Crown winner of the last half-century. There’s a lot of 2025 left to go, but the man sometimes known as Arson Judge is once again setting fire to the league. And this time, some of the factors weighing against his potentially performing the feat are no longer present.

Triple Crown stats have lost their luster as tools for evaluating overall performance, especially batting average and runs batted in, but not everything has to be an optimized evaluative tool to be cool. Bo Jackson was not even close to the best baseball players of the late 1980s, but I dare someone to say he wasn’t one of the [insert superlative used by kids today that Dan totally doesn’t know because he’s old] players of his time. Triple Crowns are fun in a way that some sabermetric Triple Crown, perhaps wRC+/sprint speed/FRV, is not. Judge is, of course, also having an insanely good season by our more nerdy numbers, but today, we’re old school. And what could possibly be more old school and sepia toned than projection algorithms?

Ryan O’Hearn has been the best hitter on an underachieving Baltimore Orioles team so far this season. Moreover, he’s been one of the best hitters in the game. The 31-year-old first baseman/outfielder boasts a 185 wRC+, a mark currently topped by only Aaron Judge, and Freddie Freeman. Over 180 plate appearances, O’Hearn has left the yard nine times while slashing .340/.428/.558.

He began to bash after leaving Kansas City, where he posted a .683 OPS over parts of five nondescript seasons with the Royals. He was designated for assignment and subsequently dealt to the Orioles in exchange for cash consideration in January 2023. Baltimore then dodged a bullet. The O’s also DFA’d him, only to see him go unclaimed, allowing them to assign him to their Triple-A roster. Called up to the majors two weeks into the 2023 campaign, O’Hearn proceeded to do what he hadn’t done with his old team: square up baseballs on a consistent basis.

Since the start of the 2023 season, the left-handed-hitting O’Hearn has the highest batting average (.286) and on-base percentage (.346), and the second-highest wRC+ (130) among Orioles who have come to the plate at least 250 times. Playing primarily against opposite-handed hurlers, O’Hearn has logged 1,042 plate appearances over that span.

How did he go from the waiver wire to laying waste to big league pitching? Read the rest of this entry »

Way, way, way back in December 2023, the Rangers signed Tyler Mahle to a two-year contract. Absolutely nobody cared at the time, mostly because the news dropped the same day as Shohei Ohtani’s first press conference with the Dodgers. But also because Mahle, then recovering from Tommy John surgery, was expected to play a trivial part, at best, in the 2024 season.

Mahle had been a bit of a hipster favorite as an upper-mid-rotation starter in Cincinnati and then briefly in Minnesota — far from a household name, but from 2020 to 2022, he’d been quite good, and in high volume. Over those three seasons, he’d averaged 27 starts, 146 innings, and 3.0 WAR per 162 team games, with an ERA- of 90. For two years and $22 million, the Rangers were conceding that he’d rehab on their dime for most of 2024. But he would’ve been available for the 2024 playoffs if they’d made it that far, and if everything worked according to plan, they’d have a workhorse no. 3 starter under contract for 2025 at a fraction of what that kind of production usually goes for.

At least in 2025, everything has been working according to plan. Mahle has made 11 starts so far this season, with the past 10 lasting at least 80 pitches and five innings. Until his most recent outing, he hadn’t allowed more than two runs in any start. Even then, he allowed only three runs in his season-worst outlier. His 1.80 ERA is fifth best among all qualified starters. Read the rest of this entry »
