Every week, we run the numbers across leagues and continents looking for teams whose results don't match their underlying performance. Sometimes the list is a global affair. This week, it belongs almost entirely to one sport. The Detroit Tigers, San Francisco Giants, and New York Mets are the three unluckiest teams in world sport right now, and all of them play in Major League Baseball. The shared humiliation is simple: the underlying numbers suggest they deserve better. In some cases, significantly better.
We track what we call a Luck Index, a composite measure of how far a team's actual results have drifted from what their run differential, expected metrics, and close-game performance would predict. A negative score means the baseball gods owe you wins. Right now, nobody is owed more than Detroit.
1. Detroit Tigers - MLB
The Tigers sit at 61-69, a record that looks like a team treading water on the way to a quiet September. Their Pythagorean projection tells a different story entirely: roughly 73 wins based on runs scored and allowed. That 12-win gap is the largest in the major leagues and one of the widest we've tracked in any sport this summer. Their Luck Index sits at -60.
Twelve wins is not a rounding error. It is the difference between a team shopping relievers at the deadline and a team buying them. Detroit has been competitive in far more games than their record reflects, losing a disproportionate share of one- and two-run contests while winning their blowouts. The pattern is textbook finishing variance, and it's been grinding away at them since May.
Regression, if it comes, would put them squarely in the wild card conversation. Whether it arrives in time is another question.
2. San Francisco Giants - MLB
San Francisco's 52-78 record is the worst of the three teams on this list, and no luck score is going to turn that into a playoff roster. But the Giants' Pythagorean projection of approximately 57 wins means they're five wins worse than even a generous reading of their talent level would suggest. Their Luck Index of -56 reflects a team that has found creative new ways to lose close games all season.
The Giants rank near the bottom of the American League in one-run game winning percentage despite posting a run differential that belongs to a merely mediocre team, not an actively terrible one. They are bad. They are not, by the numbers, this bad.
Sometimes the cursed luck score just confirms what the eye test suspects: a team that can't catch a break in the late innings, night after night, until the losses calcify into something that looks like who they are.
3. New York Mets - MLB
The Mets are 59-72 with a Pythagorean expectation of around 61 wins, a modest gap that still registers a Luck Index of -42. Two or three wins might not sound dramatic, but New York's underlying metrics paint a team that has been slightly better than its record in nearly every phase of the game.
Their bullpen ERA in high-leverage situations is notably worse than their overall relief numbers, a classic indicator of sequencing luck running cold. The Mets haven't collapsed. They've just had their worst moments at the worst times, consistently enough to shave a few wins off a season that was already on the margins.
In a different timeline, with the same pitching and the same lineup, they're 61-70 and telling themselves September is possible. In this one, they're five games further from the wild card than they probably should be.
The Common Thread
All three teams share the same basic affliction: finishing variance in close games. None of them are being undone by a flawed expected goals luck model or a schedule quirk. They are losing the games that could go either way, at a rate their run production doesn't support. In baseball, this tends to correct itself over time, but "over time" can mean next April, which is no comfort in August. The Luck Index doesn't care about your feelings. It also, unfortunately, doesn't care about your playoff odds.
