Comparing Tigers' return for Tarik Skubal to Mets' haul after Freddy Peralta trade

There's a number floating around this weekend that Tigers fans probably don't want to look at too closely, but here it is anyway. Baseball Trade Values, the site that assigns every player in the sport a "surplus value" beyond his salary, ran the math on the Skubal deal within minutes of it breaking.

As expected, the deal was deemed a Dodgers "underpay", which has been the consensus. The Dodgers paid the largest price for a rental trade acquisition ever, but it came out of their surplus of talent. The Tigers seemingly got the spare parts instead of the main attractions.

The Baseball Trade Values model starts with projected WAR (about $9 million a win, more for starters), docks for injury and roster risk, and leans on public scouting from Baseball America, FanGraphs, and MLB Pipeline for prospects. Real front offices reportedly use it as, in BTV's words, "a sanity check, or a benchmark." By their math, Detroit's return checked in about $6.2 million light of what Skubal was actually worth.

That gap reads differently once you set it next to the other big rental-arm swap of the weekend, so far. The Mets picked up Freddy Peralta from Milwaukee back in January, giving up two then-Top-100 names in Brandon Sproat and Jett Williams. Peralta never got going in Queens, cratering to a 4.99 ERA, and New York flipped him to Tampa Bay on Sunday.

That's $13.4 million going out for a player valued at $5.6 million — a near-$8 million premium for a pitcher BTV itself flagged as regressing, particularly on his off-speed stuff. The Rays are typically the least likely team in baseball to overpay for anything. They're usually the front office that turns the expiring value into controllable young pieces and has built a franchise out of squeezing every drop of surplus value out of a trade chip. If even Tampa Bay was willing to go nearly $8 million over model value for a diminished, walk-year Peralta, pitching was in serious demand this weekend — full price, or more, was the going rate.

What that means for Tigers fans

None of this means Scott Harris got fleeced the way some media outlets are framing it. Skubal was a true rental, and rentals sell at a discount to their theoretical peak value — that's built into BTV's model, not a knock on the return. But the Rays' number shows what a disciplined buyer was actually willing to pay this weekend for a pitcher trending the wrong way. Naturally, that makes it fair to ask why the Dodgers only had to come in light for a healthy, in-his-prime, back-to-back Cy Young winner.

The fix wasn't necessarily more players — it was better ones. Swapping Hope for Mike Sirota or Eduardo Quintero, both ahead on most outfield boards, or landing a controllable arm like Logan Henderson or Ben Brown instead of an often injured, still-developing River Ryan, would have closed a real chunk of that $6.2 million gap.

And in those cases, you're still not even barking up the wrong tree and asking for "untouchable" prospects, like Josue de Paula or Jesus Made. Nobody robbed the Tigers this weekend. But somewhere between the number Skubal was worth and the number Detroit actually got, a little more patience — or a little more nerve — was sitting right there for the taking.
