What a Tennis Moneyline Actually Tells You
A tennis moneyline shows two numbers — one for the favorite, one for the underdog — both expressed in American odds format. A negative number like -180 means you'd need to wager $180 to return $100 in profit. A positive number like +155 means a $100 wager returns $155 profit. Neither side carries a point spread; the only condition is that your
pick wins the match outright. Seeding, surface, and head-to-head records all move the line, so line movement itself tells a story before a ball is struck. We display current lines alongside recent head-to-head data right inside the match card.
