In baseball betting, “-1.5” refers to the run line, meaning the favored team must win by at least 2 runs to win the bet.
For example, DraftKings lists:
- Braves -1.5 (+120) vs. Marlins +1.5 (-140)
If you bet on Braves -1.5, Atlanta must win by at least two runs (e.g., 6-4) for your bet to pay off. If they win by exactly one run (4-3), your bet loses.
The run line adds excitement, especially when betting on heavy favorites for better odds and betting deals.
