The Data Dynamo

The recent blockbuster trade that sent two-time Cy Young winner Tarik Skubal to the Los Angeles Dodgers has left many baseball fans wondering: Why won’t the MLB implement a salary cap?

On paper, it seems like the perfect solution to prevent superteams like the Dodgers from forming. But of course, it’s always a little more complicated than just adding a consistent salary floor and cap.

Almost every big professional sports league in North America has employed a version of a salary floor and cap. Leagues like the NFL, NBA, and NHL have all capped a team’s payroll at a certain limit. The main reason the MLB has never had a cap like these leagues is one main reason: the Union.

The MLB Players Association is one of the most powerful players’ organizations in sports. The association doesn’t want to implement a cap because it acts as a ceiling and limits what players can earn on contending teams.

In Fact, the last time team owners tried to push hard for a salary cap, the players simply walked out, and the 1994 World Series was canceled.

So, the simple answer for why the MLB won’t implement a salary cap is that the players have successfully refused one for over 30 years, with no signs of change. However, the owners are actually putting an extensive salary floor and cap plan together aimed at the 2027 MLB season

The plan goes as follows:

• 171.2 million salary floor league-wide
• 245.3 million salary cap league-wide
• 50-50 Revenue splits between the players and the owners

So, what does the plan actually mean, and what are the pros and cons of this plan?

The pros:

• Competitive Balance: A salary floor and cap inherently balance out the competitiveness of the league. A cap compresses the top of the league, and the floor raises the bottom of the barrel
• A floor forces spending: Right now, nothing stops an owner from slashing payroll, collecting revenue sharing checks, and pocketing the difference. A hard floor makes tanking for profit illegal. For fans of perennial bottom-feeders, this is the single biggest upside.
• Cost certainty and franchise value. Capped leagues give owners predictable expenses, which props up franchise valuations — part of why ownership wants this. It also, in theory, lets smaller markets plan without an arms race they can’t win.
• It keeps stars distributed. In a capped world, the Dodgers can’t simply stack every elite free agent, because the cap forces trade-offs. Talent spreads out.

The case against

• It caps players, not owners. A cap is fundamentally a limit on labor’s share of revenue. Players see it as owners using “competitive balance” as cover to take a bigger cut of a growing pie. That’s why the union treats it as non-negotiable.
• Spending isn’t the whole story. The Rays, Guardians, and Brewers routinely out-compete payrolls three times their size. The A’s and, at times, the Pirates prove a floor doesn’t guarantee a smart front office. Money buys probability, not results — and MLB already has more variance than the NFL.
• A cap can protect bad owners. Meyer’s point has teeth: a ceiling gives an owner a permanent excuse. “I’d love to add that star, but the cap won’t let me” is a much cleaner story than “I don’t want to spend.”
• The luxury tax already exists. MLB has a competitive balance tax that functions as a soft cap, taxing big spenders to fund revenue sharing. Supporters of the status quo argue you can dial that up without the nuclear option of a hard cap.
• The nuance the Skubal trade actually shows. Remember: Detroit was over the proposed cap this year. They didn’t lose Skubal because they couldn’t spend — they moved him because they were out of the race and he was leaving anyway. A cap wouldn’t have kept him in Detroit. It might even have made it harder for a contender to take on his salary as a rental. The clean “cap would fix this” narrative is messier than it looks.

So where does that leave us?

The Skubal trade is going to get used as a talking point by both sides, and both will be a little bit right. Cap proponents will say: look, the best pitcher in baseball just funneled to the richest team, again. Cap skeptics will say: he was a two-month rental leaving in free agency, the small-market team got a real prospect haul instead of nothing, and the team that “lost” him was over the cap line to begin with.

What’s not in dispute is that this is the last normal trade deadline for a while. Come December, the sport very likely goes dark: no free agency, no trades, no winter meetings, while owners and players fight over the one structural question MLB has spent its entire modern history avoiding.

Skubal in Dodger blue is the appetizer. The real fight is the offseason.
