Miss distance measures how far the bat was from the ball. Home runs require the barrel. Here's how to use baseball's newest metric on home run props — and exactly where the logic breaks down.

Umpire strike zones move totals, strikeout props, and NRFI markets in ways most bettors never check. But the edge is shrinking in real time — and 2026 might be the year it dies.

Argentina came back from two goals down in the 79th minute to beat Egypt 3-2. The prediction market had them all but dead. Here's what that whipsaw actually teaches you.

The USA got knocked out 4-1 by Belgium. "No" cashed. But if you think that's because a 5% team lost, you've learned the wrong lesson — and it's the kind of wrong lesson that eventually blows up an acc

A team's win-loss record is the story. Pythagorean expectation is the truth — and the gap between them is one of the most durable edges in baseball betting.

The pros can't hide their hand as well as they used to. If you know how to read exchange liquidity, you can see where the smart money is going — and take the same side at a better price.

OddsJam's Sharp Money tool shows you where the pros are setting the trap — so you can stand on their side of the table instead of being the Joe who walks into it.

A hitter with a 20% chance to homer in a game is not a 5%-per-at-bat hitter. The difference is small, it compounds, and it's exactly the kind of edge that hides in a home run prop.

Right-handed batters hit lefties better — everyone knows that. Here's the actual size of the edge, where it's biggest, and how to turn it into a number you can compare against a price.

Baseball's summer power surge isn't only the hitters heating up. The air itself gets thinner — and the equations behind it are exact enough to compute.

Everyone on Kalshi wants the same thing: to buy a contract for less than it's actually worth. That's the entire game. The trouble is most people never define what "actually worth" means — they trade o

"Will this player hit a home run tonight?" is one of the most popular props in sports — and one of the most misread. Here's the data that actually moves the needle.

The research says Kalshi's prices are accurate — but they lag the sharp money by a measurable amount. That lag is the whole opportunity.

The best traders on Kalshi don't handicap baseball. They let the sportsbooks do that — and trade the lag.

A free tool at The Closing Line shows you exactly how much your trades might be costing you.

Yesterday I launched the scanner and showed you a 10-cent gap on Tigers–Astros. The game's been played. Here's how it resolved.

When the prediction market and the betting market price the same game differently, one of them is wrong. The scanner finds those gaps for you.

The numbers are real. Probably. But "real" is doing a lot of work, and nobody at Kalshi is rushing to explain the rest.

A new study looked at 72 million trades. The results are uglier than you'd think.

The YES side bleeds a little every day. The NO side collects rent. Here's the math nobody's running.
