Now that the lower minor leagues’ regular seasons are over, teams have commenced with instructional league activity in a traditional sense, with a select group of players from several of their affiliates working out and scrimmaging at their spring training complexes. While “Bridge League” (the unofficial period of scrimmage activity that occurs after the late-July conclusion of the Complex Level schedule) frequently includes some newly drafted players, most of the rosters are made up of the guys who have been on the complex all year. But once “instructs” begin, the talent and quality of play of these games ascends to a different level as teams test their most interesting young players or get an intimate look at prospects who might be up for a 40-man roster spot during the winter. The snowbirds haven’t returned in full because the weather here in Arizona is still pretty gross, so driving across the metro is easier now than it will be in a few weeks (and during next year’s spring training). For that reason, I decided to focus my early looks on teams based in the western half of the Phoenix metro, farther from the house. Read the rest of this entry »

This is the second post in a series I’m working on in which I not only do a deep dive analyzing shortstop prospects’ defense, but also cut together a video package so that you can too. The first installment can be found in the navigation widget above. Today, I’m tackling Red Sox prospect Franklin Arias, Yankees prospect George Lombard Jr., Cardinals prospect JJ Wetherholt, and Reds prospect Edwin Arroyo. Let’s get started.

Wei-En Lin is establishing himself as a prospect to watch in the Athletics system. The reason is largely two-fold. Signed by the AL West club out of Taiwan last summer, the 19-year-old southpaw has been opening eyes with an impressive combination of strike-throwing and an ability to miss bats. Over 77 1/3 innings between Low-A Stockton and High-A Lansing, Lin has logged a 33.8% strikeout rate and a 5.5% walk rate. Recently added to The Board with a 40+ FV, he currently ranks 14th in the A’s system.

His arsenal comprises a four-seam fastball, a slider, a curveball, and a changeup, the last of which Lugnuts pitching coach Dave Burba considers the best of the bunch. The erstwhile big league hurler described the pitch as “dirty,” adding that Lin not only gets good action with it, he delivers it with good arm speed. Eric Longenhagen likes it as well. Asked for his assessment, our lead prospect analyst shared the following:

His changeup is good. It has big parachute action, and it really dies as it reaches the plate. It’s slow, like 76 mph on average, and that’s weird enough to create some uncertainty as to how it will play against big leaguers. It definitely has bat-missing movement, though.

The pitch in question is gripped in an atypical manner. When I talked to Lin last week, I learned that he stopped throwing a splitter at the end of May and now attacks hitters with a Vulcan. Read the rest of this entry »

I’m not telling our readers anything they don’t already know, but defense is a very important part of baseball, especially at the up-the-middle positions. You probably watch enough baseball to list the best and worst couple of defenders at each position with a fair amount of accuracy; I bet you’d nail most of them off the top of your head (aside from Trea Turner, I think the 2025 FRV list is damn good), and that you have a proper appreciation for the importance of defense at the premium positions, even if it comes with some amount of sacrifice on offense.

In the prospect realm, though, things are trickier. Prospect hit data from TrackMan and Hawkeye has become common in public-facing analysis and discourse, but defense remains something of a black box. There aren’t many publicly available minor league defensive stats, and so much of evaluating defense is still best done visually, at least in my opinion. I wrote a version of today’s piece a few years ago, wherein I performed the same sort of video deep dive that I use to evaluate top shortstop prospects’ defense, and ripped and edited together key plays from that deep dive to share with you.

This year, I’m turning that exercise into a series. I’m going to batch together a few players at a time until I’ve gone through all of the 50 FV shortstops, as well as a few key prospects with lesser grades. That will include all of the players linked here, plus a few more. Read the rest of this entry »

Beginning last Thursday and continuing through the weekend, several key rehabbers made appearances in the upper levels of the minor leagues. A few might have a meaningful impact on playoff races, while others are scuffling. I dish on eight pitchers below. Read the rest of this entry »

We’re in the phase of the minor league calendar where the domestic complex league seasons have ended, in order to accommodate the incoming draft classes, while the rest of the minor leagues continue with their regular seasons for a few more weeks. There are some recent draftees who have already been sent out to affiliates, but the majority have gotten going at their respective facilities during unofficial “Bridge League” or “Continuation Camp” activity with loose, flexible schedules and start times. There’s a big group chat in which scouts and development personnel (plus a handful of media folks, and probably a clandestine autograph hound or two) exchange lineups and pitching probables to keep everyone abreast of the goings on. Ceasing official play in Arizona and Florida allows teams to onboard their draft classes in an unofficial setting and avoids the traffic jam of minor roster spots, which would exceed the allowed amount if the draft classes were just assigned to affiliates right away.

This is also a fruitful place for rehabbers to see their first real game action since injury because teams can just “roll” innings whenever they feel like it. If you’re on a 25-pitch limit and you’ve hit your count without getting three outs, the inning will just turn over regardless of how many guys are on base. This setting is about development and is not an actual game, so it’s a safe place to shake off rust and work up a sweat. On Tuesday, when the Padres officially caught the Dodgers in the NL West race, I saw their Bridge League teams square off with two rehabbing members of their 40-man rosters getting an inning of work at the start of the game. In this piece, I’ll pass along how Kyle Hurt (Dodgers) and Bradgley Rodriguez (Padres) looked and examine whether either team has a postseason pitching weapon lurking in the minors.

Kyle Karros has quietly emerged as one of the most promising prospects in the Colorado Rockies system. Since being drafted in the fifth round two years ago out of UCLA, the 23-year-old third baseman has slashed .303/.393/.455 with a 134 wRC+ over 1,000 plate appearances. His numbers this season are in that same ballpark. Over 305 plate appearances, the bulk of them with the Double-A Hartford Yard Goats — he was promoted to the Triple-A Albuquerque Isotopes on July 18 — Karros is slashing .297/.398/.463 with a 142 wRC+.

As our lead prospect analyst Eric Longenhagen wrote back in January, the son of former Los Angeles Dodgers slugger Eric Karros “needs to develop power.” The progeny’s right-handed stroke produced 15 home runs a year ago, and this season he has left the yard six times. Given his 6-foot-5, 220-pound frame, there is a pretty good chance that he will tap into his power with more experience. Longenhagen recently updated Karros to a 40 FV prospect while ranking him 14th in the Rockies system.

On the eve of his becoming an Isotope, Karros discussed his approach to hitting, as well as his baseball relationship with his father.

David Laurila: How would you define yourself as a hitter?

Kyle Karros: “I’ve really bought into being a complete hitter first, and allowing power to just come naturally. I’ve kind of always put an emphasis on not chasing homers. Doubles are my game. I also feel like you grow into home runs. You learn what counts you can take advantage of. You get more efficient with your swing. But right now — this year, especially — I’ve bought into really controlling the zone. I think what allows me to do that is having a right-center type of approach. That allows me to let the ball travel a little deeper. If I’m on a fastball to right-center, that puts me on offspeed where I’m able to pull and elevate.”
