That shit says River Ryan 0.1 million 😂 Great model guys
Baseball Trade Values@BaseballValues

Today the #Dodgers reportedly acquired LHP Tarik Skubal ($30.2M surplus trade value) from the #Tigers in exchange for OF Zyhir Hope ($22.4M) and RHPs Brady Smith ($1.5M) and River Ryan ($0.1M) ($24.0M ttl). The deal is accepted by our model as a moderate underpay by Los Angeles.

@FutureDodgers You’d think people like this would understand that even the 10th ranked prospect in baseball historically will probably turn out to be a replacement level to decent everyday player, not a star - the vast majority fizzle out

Oh no, as it turns out, some prospects don’t pan out. This is news to me, a person who has an account specifically for prospect content.

@FutureDodgers Yes, they are all overrated

@FutureDodgers Our model certainly agrees with you, Ryan is a mature pitcher and perhaps never will be elite but even a consistent 3-5th starter holds more value than zero x.com/rosternomics/s…

Perhaps the second most important player in the deal being quite literally zeroed out might be a flaw in the model
Baseball Trade Values@BaseballValues

@AdamMcCalvy Our model, at least, sees that package as significantly more valuable than what the Dodgers gave up:

You’re proposing there’s some kind of collusion between baseball media and MLB to inflate Dodgers’ prospect values, such that front offices will blindly trade for bad players Because they’ve been tricked into thinking they’re good? Yeah that’s not how the real world works or how orgs make decisions

@JeffPassan An incredible return for Detroit and a trade that could age very poorly if the Dodgers don't figure out an extension x.com/rosternomics/s…

The Sox win the trade in terms of both net WAR and surplus value. The Castillo contract (although bad in a vaccum) is better than Dominguez’s. Plus you get a veteran who can hopefully improve you a young and developing pitching staff. Never thought I’d be a cheerleader for Luis Castillo but here we are

Gonna be honest. I do not get it. I’ve been wrong before, but I don’t. This is trying up more 2027 payroll in a below-average player and doesn’t seem to do anything to raise confidence in the 2026 postseason rotation. Didn’t give up a lot, but how does this make us better?

BREAKING: The Chicago White Sox are acquiring right-hander Luis Castillo in a trade with the Seattle Mariners for reliever Seranthony Dominguez, outfielder Nolan Jones and catching prospect Boston Smith, sources tell ESPN.

Granted they do get Jones on a minor league deal, although it's been a while since he's been a productive major league player

Of the two, Castillo's contract is the better one to have on the books (assuming he doesn't hit his vesting option in '28). He'll give you more volume and less volatility. Why did the Mariners want a relief arm this bad? Seemingly they were desperate to get rid of Castillo, but why didn't they target a bat in return? Presumably the market for Castillo was thin.
Bob Nightengale@BNightengale

The Seattle Mariners free up about $30 million in the Luis Castillo trade with the White Sox, making ownership happy, but they still desperately need a bat.

@UnderdogMLB @JeffPassan x.com/rosternomics/s… Despite offloading Castillo, Domiguez' high salary is the thing that flips this trade negative for Seattle - ultimately the model doesn't like paying a relief pitcher $10M AAV for production that flirts with replacement level

We're currently fixing a data problem with Luis Castillo's contract - a naming collision has resulted in him being shown as making a lot less than he should be. A fix will be deployed shortly with the full grade - thank you for your patience and stay tuned.
