MLB Run Line Picks Today — When to Lay -1.5 Runs
Run-line picks for today's slate. The standard MLB spread is -1.5 for the favorite; we flag matchups where laying the line beats the moneyline price.
The run line is worth playing when a heavy favorite's moneyline price is so short that laying -1.5 runs still returns acceptable value — we flag those spots daily and skip the ones where the margin is too thin to justify the extra risk.
What is the MLB run line and why does it matter today?
The standard MLB run line sets the favorite at -1.5 runs and the underdog at +1.5 runs. The favorite must win by two or more runs to cover; the underdog can lose by one and still cash the ticket. For a full breakdown of how the math works on both sides, see our guide on what the MLB run line is and how -1.5 and +1.5 work in baseball betting.
The practical appeal is straightforward: when a moneyline sits at -200 or shorter, the run line on that same favorite typically prices out near -130 to -150, improving the return on a winning wager. That gap is where run-line value lives.
When should you lay -1.5 runs instead of the moneyline?
We apply a simple filter: if the moneyline favorite is priced at -180 or shorter, the moneyline usually offers better risk-adjusted value because one-run wins happen often enough in baseball to punish the run line regularly. At -200 or worse, the run line becomes worth examining. At -250 or beyond, laying -1.5 is almost always the sharper play on price alone.
Pitching matchup depth matters too. A game featuring an ace against a weak rotation spot, backed by a strong bullpen, raises the probability of a multi-run win. Conversely, a bullpen-heavy, late-game slugfest is exactly where favorites squander leads by a single run. For how to read those pricing signals, our guide to reading MLB odds in American format walks through the arithmetic clearly.

Run line vs. moneyline — a quick comparison
| Scenario | Moneyline bet | Run line (-1.5) bet |
|---|---|---|
| Favorite wins by 1 run | Win | Loss |
| Favorite wins by 2+ runs | Win | Win |
| Favorite loses outright | Loss | Loss |
The table makes the tradeoff concrete: the run line sacrifices one-run victories in exchange for longer odds. On a -240 favorite, that trade frequently makes sense; on a -140 favorite, it usually doesn't.
How the vig shapes run-line value
A standard -110 / -110 market carries a house edge of roughly 4.55%. Run-line markets are often priced closer to -115 / -105, which drops the edge to approximately 3.2% — a meaningful difference over a full season of wagers. Understanding that embedded cost is essential; our breakdown of juice and vig in MLB betting explains exactly how the house edge is baked into every line you see.
Sportsbook selection also affects the number you get. DraftKings, FanDuel, BetMGM, and the other licensed books price run lines slightly differently from game to game; shopping for the best number is a discipline worth building. Compare options on our MLB sportsbook comparison page.
