The GetCloseline.io MLB betting model
The GetCloseline.io MLB betting model prices every game on the schedule — moneyline, run line and total — and surfaces only the bets where its number beats the vig-free market price. Baseball is arguably the best sport for a systematic model: 2,430 regular-season games, mature markets, and outcomes driven by measurable inputs like starting pitching, bullpen strength, park factors and lineup construction. That combination gives a disciplined pricing edge both the signal to work with and the sample size to prove itself.
The model's job in baseball is patience. It does not manufacture an opinion on every game; most of the time it agrees with the market and passes. When a starter is mispriced, a total has not caught up to a weather or park shift, or a run line offers value the moneyline does not, it flags a +EV bet, attaches a confidence, and sizes it with fractional Kelly. Over a full season those small, repeated edges are where the record comes from — no single game is meant to carry the record.
As with every league we cover, the MLB record is public and graded automatically from official final scores, reported as win rate and record with losses shown next to wins. Closing-line value matters especially in baseball, where markets are sharp and beating the final number is a stronger signal of skill than any short-run win rate. If the model is genuinely pricing games better than the market, that is where it shows up first — which is why we watch it internally.
What the model prices in baseball
Starting pitcher quality and matchup, bullpen strength and recent workload, lineup and platoon splits, park factors, and weather for totals. Those inputs feed a true probability and a true total, which the model compares to the vig-free market. Moneyline, run line and total are each priced separately, because value in one does not imply value in another.
How MLB performance is tracked
Every MLB pick is timestamped before first pitch and graded automatically from official final scores. The record reports win rate and W-L, broken out so you can see moneyline versus run line versus totals. Underperforming combinations are pulled back and re-tested rather than quietly buried — the same self-correcting loop we run across every league.
