The MLB Contract That Paid for the Past and Billed the Future

Vladimir Guerrero Jr. said something most economists would sign off on, and it still cost him a public apology. Shohei Ohtani slumped just as publicly a few weeks later, and the conversation about him was entirely different.

Every long contract makes two promises: that a player will keep producing, and that the team will keep paying. When production falls, those promises come apart.

In late September, as the Toronto Blue Jays played out the end of a lost season, Guerrero said in a Spanish-language interview that his contract was not payment for future production. In the AP’s translation, he said, “They didn’t pay me because I’m going to hit 40 every year.” They paid him, he added, for what he had already accomplished. After the elimination he said he did not regret the comments. Two days later he apologized, saying his fans and teammates needed to hear it from him.

The deal is a 14-year, $500 million extension, and 2026 was its first season. By the time Toronto was eliminated, Guerrero had hit nine home runs, the fewest of his eight-year career outside the shortened 2020 season.

Three weeks later, the biggest contract story moved to Los Angeles. The Milwaukee Brewers swept the two-time defending champion Dodgers in the NLCS, ending a bid to become the first team since the 1998–2000 Yankees to win three straight titles. Ohtani, in the third year of his $700 million, 10-year deal, hit .192 in eight playoff games, with 10 strikeouts. His only home run came in the final game, his first since August. Manager Dave Roberts batted him sixth in Game 3, the lowest in the order since he joined the Dodgers.

The symmetry is hard to miss. A year earlier, in Game 4 of the 2025 NLCS, Ohtani hit three home runs and threw six scoreless innings to sweep these same Brewers, a game ESPN described as widely considered the greatest ever played. Milwaukee became the first team in MLB history to sweep the team that had swept it the previous postseason.

The explanation was different too. Ohtani missed two weeks in September with left knee and right biceps problems, and he said before the Division Series that he was not fully healthy. The Dodgers’ decision-makers believed his struggles had more to do with mechanics that had been altered by compensating for those injuries. Roberts said Ohtani was “all on board” with the lineup change.

Two of the three largest contracts in baseball history, two public slumps, two entirely different stories. The difference was the explanation each player made available.

Kyle Tucker signed a four-year, $240 million deal with the Dodgers, the highest annual salary in baseball history. Through 117 games he was hitting .232 with 11 home runs. He was booed at Dodger Stadium in August, where his OPS was nearly 300 points lower than on the road. But his slump did not begin with the contract. It traces to early July of 2025, including a 37-game stretch with the Cubs in which he hit .180, after four seasons as one of the most productive hitters in baseball. ESPN reported that he had been staying late for postgame batting practice, something that was foreign to him before this year, and by late September he was hitting well again.

Juan Soto holds baseball’s largest contract at $765 million over 15 years. He started his first Mets season in 2025 slowly, hitting .257 with a .788 OPS through April and drawing sharp criticism. He finished with a career-high 43 home runs and led the majors in walks. The Mets missed the postseason on the final day.

Framber Valdez signed for three years and $115 million with the Tigers in February. His first season was widely called a disappointment: 10-12 with a 4.03 ERA, and a back injury along the way. Then he allowed six runs over his last four starts while striking out 19.

Same contract structure, three different outcomes. That is the first clue that the contract itself is not the main cause.

The research says maybe, a little, sometimes, and it depends on how you measure.

Krautmann and Solow studied 527 free-agent hitters who signed multi-year deals between 1997 and 2007 and found a first-year drop-off, except among players near the end of their careers. They described the effect as small and concentrated at the start of the longest deals. Krautmann and Donley found no shirking in raw performance, though a value-based test suggested multi-year signers produced less than expected. Maxcy, Fort, and Krautmann rejected the idea that players strategically turn it up before negotiations. A University of Michigan study estimated a shortfall of about $1.6 million a year for each additional guaranteed year, and a Missouri study of more than 230 NBA and MLB players found a post-signing slump below the pre-contract baseline, which the authors explained through motivation theory.

That is a first-year effect on very long deals, which fits Guerrero, Tucker, and Valdez. It does not fit Ohtani, who is in year three, or Soto, who rebounded. And the central problem in this literature is that researchers must estimate how well a player should have performed, while players who have big seasons are the ones who sign big deals.

Start with the statistics, because they make Guerrero’s sentence accurate.

Regression to the mean: When a measurement is unusually high, the next one is likely to be closer to the average, because part of the extreme result was luck. Players are signed on their best seasons, so some decline after signing is a statistical expectation, not evidence of lower effort.

Winner’s curse: In competitive bidding on uncertain value, the winner tends to be the bidder who most overestimated it, so the winning price systematically exceeds true value.

Tucker is the clean illustration. Teams bid on his 2021 to 2024 peak, and the contract arrived at the trough. Ohtani’s 2025 Game 4 is the extreme case: the most extraordinary single performance is the one least likely to be repeated. A $500 million price embeds the best version of a player, not the expected one, and Guerrero was telling the truth about that.

The problem is that a contract is two contracts.

Psychological contract: The unwritten expectations between an organization and the people in it about what each owes the other, separate from the formal terms. Violations tend to damage trust more than equivalent changes to written terms, because the person experiences a commitment being withdrawn.

The legal contract guarantees money and prices the past. The psychological contract held by fans, teammates, and the front office is forward-looking. By saying what he was not paid for, Guerrero disclaimed an obligation no document ever contained, and everyone who held it noticed.

That still does not explain why Ohtani’s slump and Guerrero’s comment landed so differently.

Attribution theory: The study of how people explain behavior, either by stable traits and intentions (dispositional) or by circumstances (situational). Observers tend to overweight dispositional explanations, a bias known as the fundamental attribution error, unless a credible situational cause is visible.

Ohtani put a situational cause on the table, and it was specific, visible, and endorsed by the team: a left knee, a right biceps, and mechanics distorted by compensating. Guerrero’s sentence supplied the opposite, a reason to believe he did not feel he owed anything. Tucker offered neither. He had no visible injury, and his extra work happened where the crowd could not see it, so the stands defaulted to character. That is the mechanism that sorted three similar slumps into three different narratives.

Guerrero’s first defense was that he was not lying. That answers a question about accuracy. His audience was asking a question about commitment.

Contrast the signals around Ohtani. The manager publicly kept faith in him and announced that he was on board with the lineup change. The injury explanation arrived before the slump became a verdict. For a record contract, observers are listening less for what the player says about the past than for whether he signals he still owes something going forward.

Any organization that pays for past results with guaranteed money faces this problem: tenure raises, retention packages, executive contracts, promotions. The fix is to design the narrative around the money as deliberately as the money.

• Say what the money is for going forward, at signing, and rehearse how to talk about it when things go badly. The paperwork encodes the past. The forward commitment lives in the psychological contract, so it has to be stated before the first bad stretch, not after.

• Anchor expectations at the expected value, not the peak. Benchmark against a regression-adjusted projection. Otherwise ordinary decline reads as betrayal and ordinary variance reads as shirking.

• Surface the situational explanation early. If a real cause exists, such as injury, role change, or a new system, say so before the audience supplies a dispositional one. Ohtani did this before the slump hardened into a story.

• Separate effort, health, and luck with leading indicators. Outcomes alone cannot distinguish them. Preparation, workload, and availability can, and Tucker’s extra batting practice is the kind of evidence that outcomes hide.

• Match structure to the behavior you want. Where forward effort matters and can be observed, tie part of the pay to it, and be explicit about what is guaranteed and why.

• These are a handful of stars in a single season, chosen because they made news. Injuries are live explanations in nearly every case, including Guerrero’s back and hamstring problems and concussion, Ohtani’s knee and biceps, and Valdez’s back. Soto’s strong first year and Valdez’s strong finish are reminders that stories about contracts overrepresent the failures.

• The research is mixed and the effects are small. Several studies reject shirking, one finding depends on the metric, and the strongest results cluster in the first year of the longest deals. Ohtani’s third-year slump and Tucker’s pre-contract decline point away from a contract effect.

• Guerrero’s statement is economically defensible, and guaranteed money has real value. Pay does generally price past performance, and his deal includes a record $325 million signing bonus that protects the money from a possible work stoppage. Shifting more pay to future outcomes moves risk onto the player and could make top talent harder to sign.

• Intent is contested, and the remarks were translated. Joey Votto argued translation should not provide cover, Vernon Wells felt the comments were not meant to be dismissive, and Pedro Martinez defended his intent. No framework here settles what he meant.

• A visible situational explanation does not always protect you. It works when the audience trusts the source. Where trust is already thin, an injury report can read as an excuse.

If someone you pay well for past results has a down stretch, what explanation have you made available to the people watching, and did anyone say out loud, before it happened, what the money is for going forward?
