The Detroit Tigers, San Francisco Giants, Los Angeles Angels, Valencia, and Coventry City play in different leagues, in different countries, in different sports. What they share this week is a single, specific humiliation: the underlying numbers say they should be winning more, and in some cases a lot more. Our cross-sport luck index, which synthesizes run differentials, expected goals, and schedule-adjusted finishing variance into a single score, has all five deep in the red. These are not necessarily good teams. But they are, by measurable standards, better teams than their records will ever show.
1. Detroit Tigers - MLB
The Tigers sit at 70-79. Their Pythagorean projection, based on runs scored and runs allowed, says they should be around 82 wins. That 12-win gap is the largest negative discrepancy in Major League Baseball right now, translating to a cursed luck score of -62 on our index.
A gap that wide almost always points to one thing: close games. Detroit has been losing the coin flips, the one-run games, the late-inning collapses that turn a decent team into a below-.500 one. Their run differential says they belong in the wild card conversation. Their actual record says they belong on the couch in October.
Twelve phantom wins is not a rounding error. It is a full month of baseball that the Tigers earned and never received.
2. San Francisco Giants - MLB
San Francisco's 62-88 record is grim. Their Pythagorean projection of roughly 67 wins is also grim, just meaningfully less so. The mlb luck index has them at -57, second only to Detroit among all 30 clubs.
Five wins may not sound like a canyon, but for a team already struggling, it is the difference between a rebuilding year and a historically bad one. The Giants' run differential suggests a team that loses plenty of games on merit but also loses a conspicuous number it had no business losing. Their record in games decided by two runs or fewer has been brutal, a pattern that tends to self-correct, usually after the damage is already done to the standings.
3. Los Angeles Angels - MLB
The Angels are 56-93. Pythagorean expectation pegs them closer to 66 wins, a 10-win gap that produces a luck index of -53. Three consecutive seasons of bottom-tier records have made it easy to dismiss this roster entirely, but the run differential tells a slightly more complicated story.
Los Angeles has scored enough runs and allowed few enough, relatively speaking, to have avoided the 90-loss threshold altogether. Instead they have blown past it with five weeks still to play. Regression to their true talent level would not save this season. It would merely make it less embarrassing.
4. Valencia - La Liga
Four matches into the La Liga season, Valencia have zero wins, one draw, and four defeats, good for a single point. Their expected points total, derived from expected goals luck models that measure shot quality created and conceded, sits at 5.4. That gives them a luck index of -30.
Small samples are volatile, and five matches is a small sample. But Valencia have been consistently unlucky in a way that the xG data captures clearly: they are creating chances, conceding relatively few high-quality ones, and losing anyway. The finishing variance on both ends, their own forwards underperforming and opposing attackers overperforming, has been stark. In a relegation fight where every early point matters, 1 instead of 5 is not a quirk. It is a crisis.
5. Coventry City - Premier League
Coventry, newly promoted and still finding their footing in the top flight, have zero points from four matches. Expected points models say they should have 4.1, which would represent a perfectly respectable start for a promoted side. Instead they have nothing.
Their luckscore of -22 is modest by MLB standards but significant in a league where the margins are razor-thin and the sample is only 38 games long. Coventry have been competitive in matches their points total does not reflect. The question is whether regression arrives before confidence erodes.
The Common Thread
Across five teams, two sports, and three leagues, the pattern is the same: finishing variance. These clubs are not being outplayed as thoroughly as their records suggest. They are losing the margins, the tight games, the sequences where a shot hits the post instead of the net or a bullpen arm leaves a fastball two inches too high. None of them are world-beaters. But all of them, according to the numbers, are better than this.
