How the split works
01
Convert both prices to decimal odds so the moneyline and runline are on the same scale.
02
Allocate the stake so the moneyline leg returns your risk on a one-run win, leaving the runline as the profit leg.
03
Read the effective odds — the true price of the combined position versus the moneyline alone.
Runline questions
- What is a runline calculator?
- A runline calculator sizes a paired moneyline and −1.5 runline bet so the two positions share a defined risk. You enter the moneyline price, the runline price, and your total stake; it returns how much to put on each side and the effective odds of the combined play.
- Why bet the runline instead of the moneyline?
- The runline (−1.5 for the favorite) pays more than the moneyline because it demands a win by two or more runs. Pairing the two lets you take the better runline price while the moneyline leg cushions a one-run win. The calculator shows the trade-off in exact dollars.
- How do I convert a moneyline to a runline?
- There is no fixed price map — the fair runline number depends on how often a team wins by multiple runs, which varies by matchup. Start from the moneyline’s implied win probability, then use the calculator to size a combined ML and RL play at the prices your book is actually offering.
- Is the runline calculator free?
- Yes. The calculator is free and requires no account. Tracking your graded results and closing-line value is part of RunLC Pro.
