What a Tennis Moneyline Actually Tells You
A negative number — say -180 — means that player is the favorite; you'd need to wager $180 to return $100 in profit. A positive number — say +150 — marks the underdog; a $100 wager returns $150 in profit if they win. The line shifts as money moves in on either side, so the number you see at open can look
very different by match time. Checking line movement before locking in your wager is one of the most practical habits in tennis betting. Our sportsbook displays both current and opening lines so you can see where the sharp money has landed. Availability depends on state law and eligible states.
