What a Tennis Moneyline Actually Tells You
A moneyline price on a tennis match is expressed as a positive or negative American number. A negative number — say -160 — means you'd wager that amount to return $100 in profit. A positive number — say +130 — means a $100 stake returns $130 in profit if your pick wins. The stronger the favorite, the larger the negative number. Tennis
suits this format well because every match ends with a single winner, so there's no tie to account for. Straight sets, tiebreaks, or a retirement — the outcome is always clear.
