How MLB Moneyline Odds Actually Work
A negative moneyline number — say -150 — tells you how much you need to wager to return $100 in profit. A positive number like +130 shows how much profit a $100 wager returns if your team wins. The gap between the favorite and underdog lines is where the sportsbook's margin sits. On avvabet, moneyline odds update as starting pitchers are confirmed
and injury reports drop, so the number you see at lineup-lock can look very different from the opener posted Sunday night. Tracking that movement is one of the sharper habits you can build around MLB wagering.
